Fine Offset/Ecowitt weather stations,
their clones* and pertaining sensors

(* Ambient, DNT, ELV, Froggit, GARNI, Huygens, Misol, PanTech, ProTech, Steinberg, Tycon, Waldbeck, Watson …)

the purpose of this WiKi is
- to give an overview of the FineOffset/Ecowitt Weather Stations aka the Ecowitt ecosystem
- to show compatibility and expandability of consoles and sensors
- to provide information which is sometimes not easy to find in the manuals
- to provide background information which you don't find in the manuals
- to provide information about firmware: how to upgrade, latest not documented features etc.
- to provide help you may not find in this quality and extent on the resellers' Facebook user groups (provided they exist)
- provide help with potential issues and problems you may encounter with your weather station

the Wiki is kept up-to-date whenever changes or new information become available and can claim to be the best source of Fine Offset/Ecowitt weather station related information in the internet in English language - the related forum is www.wxforum.net and the
Ambient Weather and Ecowitt and other Fine Offset clones subforum or board at
https://www.wxforum.net/index.php?board=111.0
It has grown from the thread/topic
MUST READ - Fine Offset Clone Models,sensor compatibility,firmware + other info
https://www.wxforum.net/index.php?topic=40730.0

As it had grown bigger and bigger over time and difficult to work through due to the limited features of the forum software, the composer of that MUST READ thread has decided to host it inside an open source WiKi software where the information can be accessed, paged through etc. more easily. Over time more information gained in the forum and elsewhere will find entry here.

Hints and information regarding the FineOffset/Ecowitt and reseller (clone) hardware and software (firmware) have been verified with the manufacturer (FO/Ecowitt) and can be considered reliable.

Some tweaks or “hacks” might be experimental only and may change over time as they might result from deep diving and digging into the Ecowitt console and sensor firmware and their reference may have changed as these insights were not officially published by the manufacturer. Those will be marked “experimental” to distinguish them from officially confirmed information.

There are several companies selling Fine Offset hardware. We informally call them Fine Offset clones.
Fine Offset (earlier: Fine Offset Electronics Co., Ltd.,FCC Wireless Applications, Hong Kong, China; registered 2006 - nowadays named: Shenzhen Fine Offset Electronics Co., Ltd.) doesn't directly sell any hardware to the end customer under their company name. Their retail branch (B2C)* runs under the brand name Ecowitt. There are reseller companies in all parts of the world which acquire bulk hardware from Fine Offset (B2B)* and usually put their branding on the hardware and often use different model numbers and even different part numbers for the same stuff. There can be several differences though to keep in mind. For example one reseller brand may only provide a certain frequency (RF) for their sensors and consoles, which means that mixing brands would not work when the frequencies are different. Even when the frequencies match, sometimes the parts can possibly not be compatible because of firmware differences by each company (see Ambient and Garni). The purpose of this WiKi is to explain these differences and help users to better customize their stations and provide more options. Do also keep in mind that some reseller companies sell Fine Offset hardware along with other hardware that comes from yet different manufacturers and consoles and sensors not listed here are most likely that and therefore not compatible with the Fine Offset hardware.
* B2C: business to customer - B2B: business to business

Only the consoles and sensors shown and mentioned here are compatible amongst each other, provided they transmit/receive at the same frequency (RF) and their firmware is fit for processing. The matrix below will show the compatibility. More details can be found in the respective console/sensor sections.

Shenzhen Fine Offset Electronics Co., Ltd. are the manufacturer of the weather stations described and discussed here. They are the factory (target group: resellers/business customers e.g. Ambient, Froggit, Misol, …) whereas Ecowitt are FineOffset's private customer outlet/front (target group: retail, private users) both being involved in research and product development. While the resellers sell usually only a (sometimes very small) portion of the FO portfolio, Ecowitt sells the whole range of weather stations and sensors manufactured by Fine Offset to the end customer. Selling certain models to certain countries may be restricted due to a special contract (e.g. the Ecowitt HP2553 station is not sold by Ecowitt to a USA address due to a special agreement with Ambient).

Ecowitt show their B2C portfolio of weather stations and sensors at https://www.ecowitt.com
Ecowitt sell their equipment via their own web shop https://shop.ecowitt.com and via other distribution channels like Amazon (DE, IT, UK, US, CA, AU) or AliExpress in a dedicated Ecowitt store.
(the Fine Offset website https://www.foshk.com is for demonstration and business customer information purposes only.)

BTW - you can have multiple consoles (with or without display) - with the same or with different sensors
The latest consoles, the GW1100/GW1200/GW2000 (matchbox size/11 cm soucer size), are low-cost but very powerful display-less consoles

Ecowitt weather stations and available add-on sensors show an amazing product bandwidth from a simple (1-3) thermometer only display console via 5,6,7-in-1 sensor arrays up to a host of different single or combo-sensors which can be added to the respective weather station kit. Some stations are not expandable and others expandable “to the brim”.
Recently intelligent sensors/IoT devices have been added.
All that (in spite of the usual low-cost/low-quality image of China-based hardware) in high quality with affordable pricing and excellent customer support. This is documented in many experience reports/posts in wxforum.net and not just cheap advertisement.

This WiKi describes the whole bandwidth including related topics

want to buy a new weather station from the Fine Offset/Ecowitt “universe” ?
looking for some decision help ?
see next chapter 1a what station to buy

A Personal Weather Station or Private Weather Station (PWS) - as opposite to an official weather station run by a governmental institution or agency under the rules of the World Meteorological Organisation (WMO) - is an appliance which collects weather data of your microclimate at the place where you install it.
you can try to set up your PWS close to the recommendations of the WMO, but there is no obligation, and there may be good reasons for you to know your microclimate data rather than standardised weather data.

The goals of official weather institutions for using their weather stations and those of private persons owning their PWS are mostly quite different. Still, both can benefit from each other's experience and data.

When you have a greenhouse, it is probably more important for you to know the actual data in there (temperature, humiditdy soil moisture …) rather than standardised values which do not reflect your local reality. Or, when you want to chill out on your balcony or in your garden, you may rather want to know the actual temperature there independent of whether this matches the WMO requirements or not.

When you have set up your outdoor sensors (a sensor array = many sensors-in-one-assembly or single sensors), you can see the actual values either on a console screen, in a Smartphone/tablet app or in a Webbrowser, locally or from a website where your console sends (posts) its data in regular intervals.

a weather station basically consists of two elements: sensors or sensor groups (sensor arrays) which read and transmit the weather data and consoles which receive and process the sensor data - a console can have a screen for display or can be displayless. In the latter case it is often called a gateway. Prerequisite is that sender and receiver work at the same radio frequency and that the firmware of the console allows for the processing of the sensors (not all consoles can process all sensors). (see also Compatibility Matrix)
Usually a modern console can be connected to a local network* (via WLAN [“WiFi”] or LAN) and send (post) its data there - and then via an internet router into the internet e.g. to a Weather Service website like ecowitt.net or Weather Underground or to a personal website.
(Almost) all Fine Offset / Ecowitt (clone) consoles use 2.4 GHz WLAN only** to connect to the local network or for the user to connect directly to the console independent of the local network via an access point (AP)/hotspot, inbuilt WLAN.
*) this process is also called “pairing” or “network provisioning” (see console->router pairing process)
** the GW2000/GW3000 consoles/gateways and the Ambient ObserverIP2/IP3 have also an Ethernet LAN port

Sensors and consoles can be compared to a radio station (sensor) and a radio receiver (console). Therefore, many consoles can receive the same sensor(s) in parallel.

The sensors transmit their data in a RF (radio frequency) band. The transmission of data at certain frequencies is regulated by national laws and international agreements.
Private Weather stations (PWS) are considered to be short range devices (SRD) and for them in different areas (continents, countries) certain frequency bands are allowed to be used as long as the range (transmission distance) is not too big. This is defined by the transmission energy of the device. The sometimes expressed wish by users to increase sensor transmission energy in order to increase their range finds its limits in these regulations.

Private Weather Stations (sensors –> console) transmit in the so-called ISM / SRD bands (ISM: industry, science and medicine) which are 433 MHz (worldwide), 868 MHz (Europe), 915 MHz (Americas, Oceania), 920 MHz (Japan, Korea)

With many PWS you find more than one sensor combined inside one physical housing unit - a so-called sensor array. Sensor arrays have advantages and disadvantages over single sensors. Their main advantage is their compactness and the ease in maintenance. The disadvantage is that having all sensors in one place is not optimal for the quality of the sensor reading results of certain observations (=weather data) and therefore a compromise.

Ideally, as per recommendation of the WMO (World Metereological Organization), the main readings of outdoor temperature and humidity, rainfall and wind should be taken at different heights:

• temperature 2 m / ~ 6.6 feet above ground
• rainfall 1 m (0-500 m a.s.l.) - 1.5 m (above 500 m a.s.l.*) / ~3.3 - 5 feet above ground
• wind 10 m - 15 m / ~33 - 49 feet above ground

in an obstacle-free environment.

*) above sea level

For a personal weather station (PWS) it may not be so highly important to abide by these recommendations. The use of single sensors will make you of course more flexible - also regarding your own micro climate.

in short:

Definition: station = console + sensors/sensor array (a gateway in the context of this WiKi is a displayless console)

*) this has changed meanwhile (mid-2022)

for the new hardware revision sensor array models (WH65/WS69/WS80/WS90) with exposition to salt particles in the air (e.g. near seaside or salt lakes) Ecowitt have developed a specially protected exchangeable outdoor T/RH sensor - this applies only to models with pluggable T/RH sensors (–> Sensors and Accessories)
beyond these sets/packages/kits Ecowitt also sell the single components (sensors, consoles) so you can compose your own console/sensor “fleet”

if you want to have solar data along with a WS85, you have two options:
1. get yourself a WS68 solar/wind array
(the WS68 wind data won't be shown together with a WS85, but can be viewed with a second console/gateway)
2. get yourself (or reuse if you already have one) a WS69
(only its solar and traditional rain data will be available when a WN32 outdoor is registered to the console/gateway)

some recent Fine Offset / Ecowitt stations see below (November 2024)

—————- WN1982 ———————————— WittField Combo

Froggit is a weather station reseller brand of HS Group GmbH & Co. KG based in Köln (Cologne), Germany, which sells 868 MHz frequency stations and sensors across continental Europe. They do not sell the full range of Ecowitt consoles (e.g. no WN1900, no WS3800) nor their IoT devices (status July 2024) and do not ship anymore into the UK after Brexit. However, they sell the widest range of Fine Offset models and sensors of any other reseller.

Froggit stations have a different naming system (see matrix) but are functionally the same as Ecowitt stations.
The only visible difference is the brand name “Froggit”.

Ambient stations
Ambient LLC, Chandler, Arizona is a USA based company (, part of the Nielsen-Kellerman Company, Boothwyn, PA) which sells Fine Offset manufactured weather stations and sensors inside the United States of America, Australia (via amazon.com.au) and South America - all with 915 MHz RF - and also maintain their own internet weather service https://www.ambientweather.net or AWN which every owner of an Ambient console can use. Separate licenses are also available on request.

They even sell stations to Europe, however, without warning/informing the customer about frequency incompatibility and legal impact of running a 915 MHz short range device (SRD) in Europe. - Also take note of our warning at the end of this Ambient section regarding console/sensor compatibility.

(* the WS-3000 is not a full-fledged weather station, it can only display up to 8 sensors of the WH31 temperature/humidity sensor family)

Not all weather stations sold by Ambient are FineOffset/Ecowitt clones !! - Only the above mentioned models and their sensors.
(to be kept in mind:
Ambient consoles only process and display Ambient branded sensors - Ecowitt consoles process and display sensors from all Fine Offset based brands*)

( *) the only exception so far is the proprietary [exclusively built for Ambient] WH48 or new Ambient CO₂ T/RH (air quality 3-in-1 combo) sensor which cannot be read by non-Ambient consoles)

There are two more important tables available:
1. how many sensors of the same type can be connected to one console (see max # sensors)
2. which sensor readings can be displayed on which console screen, which in the Ecowitt cloud (www.ecowitt.net) only, which ones in the Ecowitt app from the internet, and which ones inside the local network via the WS View Plus app and in a webbrowser user interface (WebUI) (see max # sensors, 2nd picture)

REMARKS:
General:
sensor frequencies used/allowed for Personal Weather Stations (PWS) in different areas of the globe:
Americas (North/South) - 915 MHz
Europe - 433 MHz or 868 MHz
Asia and Oceania (Australia/New Zealand) - 433 MHz (or 915 MHz)
Japan, Malaysia, Singapore & South Korea - 433 MHz or 920 MHz
(want more detail ? see https://www.analog.com/en/analog-dialogue/articles/wireless-short-range-devices.html)
a country specific list published by Ecowitt: https://osswww.ecowitt.net/support/recommended_frequency_V1.3.pdf

In general a console works (receives RF signals) at a (one !) dedicated frequency (433, 868, 915 or 920 MHz) - hence it can only receive the signals of sensors which transmit at the same frequency.

More than one console can receive the signal of a particular sensor in parallel, provided it operates at the same radio frequency and the firmware allows for the sensor reception. (e.g. a GW1000, a HP2550 and a WH2320E can all together in parallel receive the signals of one and the same WH65 sensor array. If it were the WH57 lightning sensor, a GW1000 and a HP2550 could both receive and process its signal, however, the WH2320E could not as its firmware doesn't allow for that).

Just keep in mind that sensors are (like) radio stations and consoles are (like) radio receivers.
Multiple receivers can receive the same radio station on the same frequency as long as they are in reception range.

Ambient consoles don't display nor process Ecowitt sensors, whereas Ecowitt consoles are compatible with Ambient sensors (provided they run on the same frequency [915 MHz] and are Fine Offset clones). Only Ambient consoles can post weather data to AmbientWeather.net and not to Ecowitt.net and vice versa.
Exception: the Ecowitt WH32 outdoor T/RH sensor (Ambient depreciated their WH32E version) can be received by the WS-2000/WS-4000/WS-5000 consoles.

Footnotes: (from the matrix)

a: Ecowitt (Shenzhen, China) sell 433, 868, 920 and 915 MHz sensors/consoles (www.ecowitt.com); Ecowitt don't sell all their sensors in/to the U.S. (restricted due to Ambient contract with Fine Offset§), Ecowitt sell some models/parts in the U.S. via Amazon and to the rest of the world directly or via Amazon in Canada, Australia, Germany, UK …
b: Froggit (Germany, Europe) sell only 868 MHz sensors/consoles directly (www.froggit.de), via Amazon (D, UK - no more after Brexit) or eBay; WeatherSpare (UK) offer sales and support for Ecowitt products (www.weatherspares.co.uk)
c: Ambient Weather (U.S.A.) sell 915 MHz sensors/consoles only (www.ambientweather.com). Ambient consoles are not compatible with Ecowitt sensors due to different console firmware; Ecowitt 915 MHz consoles can read Ambient sensors of the same frequency (915 MHz)
d: other brands (list may not be complete) are: ChiliTec, DNT, ELV, GARNI, Misol, PanTech, Renkforce, Sainlogic, Steinberg Systems, Ventus, Waldbeck, Watson …etc. - however not all of their weather stations offered are Fine Offset clones
1: HP3501/3500 looks like the Ambient WS-3000 console but is totally different. The Ambient WS-3000 is running different firmware and only works with Temp/hum sensors and is not intended to be a complete weather station. Needs firmware > 1.6.2 for extra sensors.
2: here is a non-WiFi version of this console sold by some resellers like Ambient, model WS-1900. It looks identical but costs less and makes for an excellent 2nd display.
3: functionality-wise same as GW1000, needs/comes with an extra T&H&P sensor and has a 5V barrel connector (the Renkforce WH2600 is the legacy LAN model, not the new WiFi model, see also footnote 6)
4: e.g. Meteobridge [Pro, RasPi], Weather-Display, CumulusMX, WeeWX, GW1000live app, PersonalWeatherTablet (PWT) app (Android), GW1100 Windows app …
5: new hardware revisions (T/RH sensor pluggable with bluish end) of the WS80 can be fully externally powered like a WS90
6: not the same as WH2600 LAN or Ambient ObserverIP (WS-1400IP, WS-1550-IP); the WH2650 is a Fine Offset model, not part of the Ecowitt portfolio - however you can get it as WH2600Pro WiFi from Froggit or e.g. under the Waldbeck Halley/Steinberg SBS-WS-600 brands from www.amazon.de or www.expondo.de (868 Mhz only) as a Weather station set ([displayless] console + T&H&P sensor + WH65 osprey 7-in-1 sensor array).
7: the predecessor model of the WH32 is the WH26 which is no longer built. The WH32 comes in two versions:WH32 and WH32-EP (extra precision). The WH32-EP has an external probe. see also Ch.13 sensor hierarchy Sensor hierarchy
The GW1000/WH2650/HP2550 consoles allow selective activation or deactivation of sensors. Per console there can be only one WH32 sensor active (either WH32 or WH2-EP). If it is active in the console, it overwrites all other outdoor temperature sensors which are active for the console. If you wanted e.g. to get the outdoor temperature sensor data of a WH65, a WS80 and a WH32 altogether, you would need to deploy three consoles (i.e. consoles from the GW1000/WH2650/HP2550 models).
A similar situation exists with the wind sensor data from WH65/WS69, WS68, WS80 and WS90 running in parallel - the consoles prefer WS90 over WS80 data over WS68 over WH65/WH69 sensor array data. You want both (all four), you need two (four) consoles with selective activation/deactivation of WH65, WS68, WS80 and WS90.
8: the whole number of indoor and outdoor PM2.5 sensors (WH41 and WH43) must not exceed four (4) devices (per console). You can have more than four such sensors, but they will then need to be distributed over more than one console. The same applies to the WH55 water leakage sensor.
9: the whole number of WH31 and WN30 extra sensors (WH31 and WH31-EP) must not exceed eight (8 ) devices (per console). WH31-EP sensors come sometimes labeled WN37xS (Ecowitt internal name) - they are still WH31-EP sensors. x=A,B,C (07-Jul-2021)
10: the WS6006 is a display-less console and a WH65/WH69E array with the possibility to add two extra sensors. Target area is agriculture. The current model uses mobile networks with 3G (UMTS), 4G (LTE) standards. The predecessor didn't have extra sensors and ran on 2G / GPRS. The still to-be-released WL6006 will run on LoRa (Long Range) technology. Number and type of extra sensors still to be determined. Since firmware 1.1.30 and PC software 1.6.9 one WN34 and one WN35 sensor can be processed additionally. Since firmware 1.1.32 and PC software 1.7.1 a WS80 ultrasonic sensor array and a WH40 rain gauge can be used instead of a WS69 outdoor array.
11: Weather Networks - WU=Weather Underground (www.wunderground.com), E=Ecowitt (www.ecowitt.net), WC=WeatherCloud (www.weathercloud.net), WOW=MetOffice WeatherObservationsWebsite (wow.metoffice.gov.uk), A=Ambient Weathernet (www.ambientweather.net), C=custom server [W= WU protocol, E= Ecowitt protocol, A=Ambient protocol] The rebranded models in the matrix (“others”) support the same Weather Networks and can use a custom server as the Ecowitt models
12: 433 MHz only
13: 915 MHz only
14: 868 MHz only
15: 868 MHz only; the Ventus W830 console displays digits only in white whereas the other brands have colored digits
16: consoles with screen - sizes (screen diagonal):
WS3800/WS39x0: 7.5“/19 cm,
HP25x0: 7”/17 cm,
HP3501: 4.3“/11 cm,
WH2910: 6”/15 cm,
WS2320: 7.1“/18 cm,
WN19x0: 4.9”/12.5 cm (portrait)
(the WS2320/WH2320E/WH4000SE console has a 4:3 LxW ratio, the other console screens have a 16:9 LxW ratio)
display-less console sizes (LengthxWidthxHeight):
GW1000/GW1100/GW1200: 2.3 x 1.2 x 0.4“ / 6 x 3 x 1 cm,
WH2650: 3 x 2.1 x 2.2” / 7.7 x 5.5 x 5.7 cm (height including antenna),
WS6006: ~4 x 2 x 0.6“ / ~10 x 5 x 1.5 cm
17: sold by Ambient ( 915 MHz) and Froggit (868 MHz), and since 30-Apr-2021 also by Ecowitt (433, 868, 915 MHz); this sensor is part of the WH31 multi-channel family (WH31x, WH31-EP and now also WN30). This means you can have maximum 8 sensors of WH31 multi-channel type (WH31, WH31B etc.) per console (see footnote 9); remember: Ambient consoles don't display Ecowitt sensors, whereas Ecowitt consoles are compatible with Ambient sensors (provided they run on the same frequency [915 MHz, 868 MHz] and are Fine Offset clones).
18: sensor data from non-Ambient Fine Offset clone consoles which have the custom server option in Ecowitt format available (WSView app –> Device list –> Weather services –> Customized) can be received and processed by Weewx with the so-called Interceptor driver. For the GW1x00/WH2650/GW2000/WN19x0 a dedicated API driver (Ecowitt gateway driver) is available. The proprietary Ambient format is not compatible with any so far existing weewx driver (as per August 2022).
19: The Tycon ProWeather TC3000WC has a console display with black letters/numbers on greenish-grayish background, similar to the Davis consoles. The other clone models have bright yellow letters/numbers on a dark blue background.
20: The 2910C console (and clones on latest device firmware (>= 2.1.9) and WiFi firmware) can receive extra sensor data from WH31 and WH41/43 sensors and publish them on Ecowitt.net. These readings CANNOT be displayed on the console.
21: the WN1900 (not to be confused with the Ambient WS1900 ) is a “low-cost console” together with a light-weight version of the WH65 sensor array (WN67) without solar panel, solar and UV sensors and longer sensor sending intervals. It can be connected to other outdoor arrays though. The console cannot display solar/UV values even if a WH65/WS80/WS68/WS90 is connected. The console itself has the same API as a GW1000/WH2650 but with a grey-green LED display and about palm-size (i.e. can be held in one hand). 8 WH31 multi channel temp/hum sensor recycle display on the console. Other extra sensors data (same as GW1100) is not displayed on the console (pass through to ecowitt.net only); sensor management/calibration via WS VIEW app only. It comes with a greyish/black display (WN1900) or a color display (WN1910) - it is meanwhile also sold for Ambient sensors under the name WS-1965. The successor model of the WN1910 is the WN1980 console. It has the same features as the WN1910, but no more bluetooth, now WiFi 802.11 b/g/n connectivity and a WebUI. The outdoor temperature/humidity is shown in a different color (red instead of orange) and the keys are no longer at the side but touch-sensitive areas on the display.
22: the WH32B has a no longer built predecessor model named WH25. A HP2550 or a WH2650 console should be able to get readings from it as T&H&P sensor. The WH32B indoor T/H/P sensor is not to be confused with the WH32 (without a B) outdoor T/H sensor. These are different devices and cannot replace each other.
23: the WN67 (N=no solar panel) is a light-weight WH65 with no solar radiation reading. It runs on batteries only and comes with the WN19x0 console. The sensor array which comes with FineOffset WN5300, WN5350, WN2080 is NOT a WN67. It is a WN14 and uses a different modulation method for transmitting the sensor readings. WN14 uses ASK=amplitude shift keying and the WN67 uses FSK=frequency shift keying. So they are not interchangeable and cannot be received by the consoles in our matrix. The sensor arrays of Aercus 2085 and Aercus 3085 also use ASK.
24: the WH65 comes as Y-shape and the newer WS69 arrays as I-shape arrays (as per Ecowitt engineering). The WS69 can use the BP0001 battery extension pack. Newer hardware revisions come with a “milky sticker”, a filter on the solar sensor (do not remove it !) - the predecessor of the WH65/WS69 is the WH24, the “boat” (because of its shape). It can be received by the newer consoles too, only some adjustment needs to be made in the device settings - otherwise the wind readings will be wrong as the way of measuring wind has changed in the WH65.
25: the GW1100/GW1200 can also be configured and connected to WiFi via a WebUI, not only via the WSView app - the GW1200 supports the new IoT devices
26: CumulusMX V13 (b3145) can use a console/server which posts in Ecowitt, Ambient or Wunderground protocol (e.g. custom server option) as a full or complementary station (adding sensors to main station)
27: the WS90 is an all-in-one outdoor array with a haptic rain counter and ultrasonic anemometer; it's not meant to be a replacement for the WS80 - It's part of a new station (Wittboy) with an all-in-one outdoor sensor array (WS90) and a new gateway/hub GW2000 which will become home automation etc. capable in the future. Its rain sensor can be calibrated on five tiers (https://www.wxforum.net/index.php?topic=43139.msg443726#msg443726). Its SHT40 based T/H sensor can be easily replaced by an extra precision SHT35 T/H sensor (https://shop.ecowitt.com/products/sht35-temp-hygr) - it can be fully externally powered Since February 2023 there is also a WN90LP with Modbus/RTU RS485 interface available - no solar panel, no batteries, heater powered via 5V data cable, inbuilt pressure sensor).
28: in Europe the WH31 comes also in a special edition with a DCF77 chip (radio controlled time signal) - this is not necessary for the normal consoles (GW1x00, HP2550 etc.); it works like anormal WH31 sensor (868 MHz) - it's sold by dnt - a WH31 can be converted into a WH32 (https://www.wxforum.net/index.php?topic=43206) - the so-called WH32F sensors (max 3) of a WH28x0 console are also WH31 family sensors with a radio time receiver. Their channels 1, 2, 3 correspond to WH31 1, 2, 7.
29: see chapter 12
30: The GW2000 console/gateway can display the rain data of both the haptic (“piezo”) rain sensor of the WS90 array and a WH40 in synoptic view (firmware 2.1.1) in its WebUI and on ecowitt.net if both are registered in the console. (https://www.wxforum.net/index.php?topic=43139.msg443769#msg443769). The GW2000 possesses a LAN and WLAN interface which can be used alternatively or in parallel.
31: the WN36 is a floating pool temperature sensor, 8 channels, the 8 channels will be shared with the WH31 family; also = Ambient WH31PF
32: via Ecowitt cloud with APP and API key
33: either via Ecowitt custom server or via WS2320E API
34: indoor T/H/P sensor already integrated in HP2561
35: the WH2682 or Ambient ObserverIP 2.0 module (Ambient Marketing name: “Weather Hub”) is a displayless console/gateway and functionally similar to an Ecowitt GW2000 console/gateway upgraded hardware which is able to receive all Ambient branded sensors (but no Ecowitt sensors due to Ambient proprietary company product policy - whereas an Ecowitt GW2000 can receive all Ecowittt (clone) sensors including Ambient sensors). The WH2682 has both an Ethernet (LAN) and WiFi (WLAN) interface and a WebUI for configuration via a web browser. If it can also be configured by an (to be updated) awnet app is not yet known. (21-Sep-2022). The old ObserverIP module (WH2600, WS-1900 - LAN only) could not receive the WS80/WS-5000 ARRAY and WH40/WS-5000-RAIN, PM2.5 and AQUIN sensors. It needs an extra indoor T/H/P sensor (WH32) like the WH2650-WiFi or the HP2551/WS-2000/WS-5000 consoles.
36: the WN1821 has an inbuilt CO2 sensor and displays WH/WN31,34,35 and WH51 - no solar, no wind, no rain no pressure
37: WS3900: 7”/19 cm display, all sensors including IoT supported, some only via ecowitt.net or WSV+/WebUI; WS3910: w/ inbuilt CO2 sensor.
*: WN34D: extended range -55 - +120°C
#: a WH46 has additional PM1 and PM4 sensors over a WH45
%: WN51 = soil moisture sensor with ceramics covered probe; under revision; no more sold
§: Fine Offset Electronics Ltd are the manufacturer, the factory (target group: resellers/business customers e.g. Ambient, Froggit, Misol, …) whereas Ecowitt are FineOffset's private customer outlet/front (target group: retail, private users) which is also involved in research and product development.

Beware that the whole number of WFC01/AC1100 devices is limited to 16. Any combination between 0/16 and 16/0 is possible.


The GW1000 and the WH2650 are no longer contained in the above matrix.
However, they can be considered the same as a HP25x0/HP350x console regarding the number and type of possible sensors which can be connected to them. In fact, on firmware 1.7.7, they both can register all Ecowitt sensors except the IoT sensors (WFC01, AC1100).
They can even display synoptically a traditional and a piezo rain gauge in the WS View Plus app while until now (February 2024) the HP25x0/HP350x consoles can only display on their screen one of the rain gauges. A cycling is not (yet ?)implemented.
The new WS85 Rain & Wind sensor cannot be registered by a GW1000/WH2650.
Their firmware will no longer be updated to support new sensors.

Now - how to read this table ? (some people seem to have difficulties to read this table properly)
you read the table per column ! Each column tells you how many sensors of which type you can maximally connect to one and the same console/gateway

a GW2000 can connect one WS90 and one WH40 and one WN32P and one WH32 and eight WH31 etc.
with the first five lines (these are the sensor arrays = many sensors in one housing), you usually choose only one, but in special cases it can make sense to have more than one

(for example: if you have a WS85 which doesn't have a solar sensor, but want also to see the solar values, you can add one more array which provides these data e.g. a WS68 which has solar and wind data. The wind data of a WS68 when combined with a WS85 will not be shown due to the sensor hierarchy, but the solar data will.)

the next table will give you a different view - what sensors can be seen on which console display/screen
on the ecowitt.net dashboards ALL registered sensors and their battery values can be seen

————————————————————————————————————————————————————————————————-

let us first come to grips with the multitude of terms used in the context of consoles. There are different words used in the manuals, forums etc. which cover a certain aspect of these devices:
(they are often used as synonyms emphasising on different functionalities which they all possess)
Basis Station, Console, Gateway, Hub.

• Basis station: the part of your weather station (console + sensor(s)) which is usually kept indoors and which processes the sensor data
• Console: a device which processes the data received from the sensors (can have a display or not)
• Gateway: a connector between networks - here between the RF (radio frequency) network of the sensors and
  the WLAN or LAN allowing the data to be sent/posted into this network (e.g. internet (WAN) via the LAN)
• Hub: a telecommunications device that (physically) connects network nodes in a star configuration
  (this refers to the RF network: console and sensors; in the local network ([W]LAN) the console is just a device and a network switch or router is the hub)

All Ecowitt consoles have all the above mentioned functionalities - therefore, the terms are interchangeable
*) exceptions are the single sensor consoles and consoles without [W]LAN connectivity like the WH28x0 consoles

Note:
All Ecowitt consoles (exceptions as mentioned before) have an inbuilt WLAN hotspot (also called access point [AP]) which can be reached via the SSID console-nameX-WIFIxxxx (e.g. GW3000A-WIFI23AC) or EasyWeather_WIFIxxxx or EasyWeatherPro-xxxxx. (the last four or five xxxxx are the last 4 rep. 5 characters of the console MAC address). The console has the IP address 192.168.4.1 in this WLAN. When you connect to this WLAN e.g. via a Laptop or a smartphone, you can reach the console WebUI by entering http://192.168.4.1 into a web browser. Of course the hotspot needs to be activatd beforehand. Procedure see manual of the respective console.

WN0290	WN0291	WN0295	WN0298

WH5360

Note regarding all Ecowitt consoles (almost all, except WS2320E and WH2910): the consoles have an optional switchable temperature compensation for the WH65/WS69/WS80/WS90 outdoor sensor arrays, whose temperature sensors are located in a relatively small solar radiation shield, which is generally exposed to full sunlight.
For those interested - the correction formula currently used, which is still being worked on, is

 
Outdoor_Temp = Outdoor_Temp - CorrectT
CorrectT = solar_rad/ (10*cp*k* sqrt(u/0.0009)
solar_rad: unit in W/m2.
cp: 29.3, k: 0.0984, u: gust (bigger value among 0.5m/s or gust ) 

Ambient consoles do not have the temperature compensation feature available
(because Ambient decided it would not be needed for their customers)

with device firmware upgrade 1.9.5 for the HP25x0 console, the algorithm was changed:
outdoor temperature compensation, changing from the average of the last eight gusts to the average wind speed over 10 minutes
it is expected that the compensation algorithm will also be changed in upcoming frimware upgrades for the other consoles which already have the temperature compensation option
————————————————————————————————————————————————————————————————-

Gateways in this context here are displayless consoles.
They usually have all the capabilities of consoles with display except for the display. Their data can still be viewed by other means like a webbrowser, apps or a special tablet/smartphone turning the tablet into a console display (e.g. PWT).
For details see the specific consoles.
(they are called gateway as they form the gate between the RF sensor-console network and the Ethernet or WiFi based [W]LAN) - in fact almost every console is also a gateway*
*) exceptions are the single sensor consoles and consoles without [W]LAN connectivity like the WH28x0 consoles

the recently (December 2024) known and available gateways *) end-of-life
————————————————————————————————————————————————————————————————-

The Ecowitt GW1000 is a matchbox-sized (small) device that has a USB 2.0 plug for power supply. In fact, this USB plug is used exclusively for power supply - there is no data interface.

In addition, a temperature/humidity sensor for recording these values in the area of the GW1000 is attached to a cable approx. 1 metre long. A pressure sensor is installed on the mainboard.

The GW1000 serves as a console (without a screen) - however, the data can be viewed in real time (!) using the WS View (Plus*) app. A popular display option for a GW1x00 is the use of an (old, new also works) Android tablet with the help of the Android app PWT (Personal Weather Tablet) see https://www.wxforum.net/index.php?topic=39453.0 (* in order to be able to connect and calibrate the WS90 outdoor sensor from firmware 1.7.4, you must use the WS View Plus app from version 2.0.32, the old WS View app can no longer do this)

The biggest advantage of this “console” is the API capability [API = application programming interface], which is also used by the WS View Plus APP for real-time data display (Live Data). Appropriately prepared software can therefore retrieve the data from the console. In July 2021, the API was finally made available to the general public.

A more detailed description can be found in the section the local Ecowitt Gateway API The GW1000, GW1100, GW1200, GW2000, WH2650 (Froggit WH2600Pro WiFi), WN1821, WN19x0 and the new WS3800/WS39x0 consoles have this local Ecowitt Gateway API aka GW1000 API.

Otherwise (with the exception of the IoT sensors, which can only be received/processed by a GW1200, GW2000, WN1980 and WS3800/WS39x0), all sensors that are currently (February 2024) available can be processed (from firmware 1.7.0 on including the WS90). With firmware 1.7.4, temperature compensation can be optionally switched on (Device Settings) to correct possible distortion of the measured values due to solar radiation. This applies to the WH65/WS69, WS80 and WS90 combined outdoor sensors. This option can only be used with WS View Plus App V.2.0.32 or higher.
The GW1000 is no longer sold by Ecowitt. Only the successor models GW1100 and GW1200. Resellers such as Misol (433 MHz) or ProTech (868 MHz) are still selling their (remaining) stocks of GW1000, Froggit as DP1500. (according to user feedback, the DP1500s sold by Froggit are now GW1100 clones (September 2022)). The functional differences between a GW1000 and a GW1100 are minimal, no WebUI, no support of new sensors like the WS85.

Froggit: DP1500

————————————————————————————————————————————————————————————————-

Ecowitt now sells the GW1100 instead of the GW1000. The GW1000 is no longer available from Ecowitt. However, other resellers are still selling their remaining stocks of GW1000s, e.g. Misol (433 MHz only), ProTech (in Sweden and Norway, 868 MHz or Hadex (www.hadex.cz) in the Czech Republic) or Froggit as DP1500 This is basically the same device (same design, same CPU - ESP8266, same functions, API support), but with more memory, in which Fine Offset has packed a web interface for configuring the GW1100. This means that it is now possible to make all settings not only via the WS View mobile phone app (which still works) but also via the device's web interface. As with WS View, there is also a live data page showing the current measured values.

All functions (as well as some points of criticism) of the GW1000 are included. The date and distance of the last lightning strike (if a WH57 sensor is present) are no longer lost after a reboot. However, the highest measured wind peak of the day is. However, I (@olicat) hope that the additional memory will also be used in future to rectify the known weak points.

A GW1000 can NOT be turned into a GW1100 by a software update - it simply lacks the necessary memory.

Since September 2022, Froggit has been supplying the device under the same name as the earlier GW1000, namely DP1500.

The functionality of the GW1100 and GW2000 (apart from the additional LAN interface of the GW2000) has been identical since firmware 2.1.2 (GW1100) and 2.1.1 (GW2000) (03 March 2022). Exceptions are, as described for the GW1000, the IoT sensors (WFC01 and AC1100) - these can only be received/processed by a GW2000, a WN1980/WN1821 and WS3800/WS3900.

The firmware itself in bytes is different in size, even though as of the end of April 2022 both have firmware version 2.1.4 (or 2.1.5 at the end of June). Since firmware 2.1.5, the GW1100 has the option of switching on solar radiation and wind-dependent temperature compensation for the WH65/WS69, WS80 and WS90 combined outdoor sensors.WS View Plus (version >= 2.0.32) must now be used as the app for live data view, configuration and calibration (WS View only works to a limited extent).Newer firmware of the GW1100 and GW2000 also allows the use of a remote indoor sensor for indoor T/RH and air pressure, the WH32B (Indoor).However, this requires hardware intervention.To do this, you have to disconnect the cable of the indoor T/RH sensor that is routed to the outside (note from Ecowitt), preferably at the soldering points on the circuit board, either using pliers or by desoldering.If the firmware does not recognise an internal T/RH sensor, it allows the registration of a WH32B (TH&P) sensor.
Since firmware 2.3.1 a separate TH&P sensor can be connected instead of the internal sensors.

This does NOT apply to a GW1000! Its firmware does not support this “switching when absent”. See also note on WH32B/WH32 indoor below.

Hardware upgrade of the GW1100, which also has sufficient computing power and memory to enable the MQTT protocol used for communication with the IoT devices/sensors (WFC001, AC1100) and the corresponding encryption. It has an Espressif ESP32 C3 SoC with a RISC-V primary processor, the successor of the ESP8266. In other words, a GW1100 with IoT capabilities. Visually, it looks like the GW1100, the colour is a dark grey. A comprehensive manual can be found at https://osswww.ecowitt.net/uploads/20231221/GW1200%20Manual.pdf

The price of the GW1200 is only marginally higher than the GW1100, which is still available However, the GW1100's years are probably numbered and it will most likely no longer be produced once stocks have been sold off. After all, there is no recognisable added value.

————————————————————————————————————————————————————————————————-

The displayless console/gateway available together with the WS90 since 1 April 2022, which has the same and in parts (when used with a WS90 7-in-1 outdoor combination sensor) extended range of functions as the GW1100 console. Like the GW1100, the GW2000 also has a browser interface (WebUI) for display and configuration. Like the GW1x00 consoles/gateways, a temperature/humidity sensor for indoor T/H measurement is led out on a cable.*) The pressure sensor is located on the mainboard. The corresponding station is called GW2001 (“Wittboy”) and consists of the GW2000 console and the WS90 7-in-1 outdoor sensor array with a haptic (“piezo”) rain gauge. This station also has a RJ45 interface to connect the device via network cable in addition to the existing WLAN interface. A fixed (static) IP address can also be assigned for the Ethernet interface. The GW2000 can also be operated exclusively via the LAN connection. However, experience to date has shown that both interfaces (Ethernet/WLAN) should not be used at the same time, as this can (so far) lead to the web interface being blocked. (Improved after firmware updates [2.1.5], but not yet fully stabilised) The GW2001/Wittboy Station has been available in the official Ecowitt catalogue and shop since 01 April 2022. The GW2000 console alone is also offered individually like the GW1100.

The GW2000 console (gateway) (firmware 2.1.1, 03 March 2022) can also display a classic rain sensor (WH65, WH40) synoptically when using a WS90 combo sensor array with haptic (piezoelectric) rain gauge. Both in the ecowitt.net dashboard and in its WebUI (web user interface). The haptic/piezoelectric rain gauge can also be calibrated in five rain rate levels depending on the rain rate in order to take into account the different behaviour of this rain gauge at different rainfall rates (mm/h). The levels are 1. 0.00 - 4.0 mm/h, 2. 4.01 - 10.0 mm/h, 3. 10.01 - 30.0 mm/h, 4. 30.01 - 60.0 mm/h, 5. 60.01 - …. mm/h

The GW1100 gateway also supports this function since firmware V.2.1.2 and the same functionality was introduced with firmware 1.7.2 for GW1000/WH2650 (May 2022).

With the HP25x0 console, since device firmware 1.6.8 it has been possible to select which of the two rain sensors is shown on the main display when the WS90 and WH40 (or WH65) are active/connected at the same time. An alternating (cycling) display, as with already implemented with extra sensors, would certainly be technically possible for the HP25x0 console, but is not yet available. Rain calibration of the WS90 via the HP25x0 console has also been possible since firmware 1.8.1.

As with the GW1x00 gateways/consoles, local data display is possible, e.g. via PWT (Personal Weather Tablet) on an Android tablet (even an old one) using the custom server function (see below).

Since firmware 2.1.5, the GW2000 has the option of switching on solar radiation and wind-dependent temperature compensation for the WH65/WS69, WS80 and WS90 combined outdoor sensors. The WS View Plus app (>= 2.0.32) must be used as the display (and configuration) app.

The GW2000 firmware has made a version jump from 2.2.5 to 3.0.4. The latter now also supports the WFC01 IoT sensor (see below)

An ESP32 CPU is installed in the GW2000.

*) the newer firmware (2.2.4) of the GW1100 and GW2000 also allows the use of a remote indoor sensor for indoor T/RH and air pressure, the WH32B (Indoor). However, this requires hardware intervention. To do this, you have to disconnect the cable of the indoor T/RH sensor that is routed to the outside (note from Ecowitt), preferably at the soldering points on the circuit board, either using pliers or by desoldering. If the firmware does not recognise an internal T/RH sensor, it allows the registration of a WH32B (TH&P) sensor. (see also the note on WH32B/WH32 indoor below).

Since GW2000 firmware 3.1.1, an alternative separate WH32B (indoor) T/H/P sensor can also be selected on the sensor IDs page of WS View Plus or the WebUI without the above hardware intervention.

Froggit have been selling the GW2000 as DP2000 since January 2023.

this gateway, the likely successor of the GW2000, has come out of the prototyping phase.
it's available for purchase since 05-Dec-2024

in addition to the GW2000 capabilities it will have a microSD slot where current data can be saved on.
The SD card will be accessible via its WebUI or via the http API and the saved data can be downloaded via the network.
Connectivity: WLAN 2.4 GHz and LAN (Ethernet) interface. All existing sensors and IoT devices supported.

it will also be wall mountable. The colour of the final product will be beige. Something between the colour on the right photo and the part description farther down.
the colours on the other pictures are from prototypes.

As per the latest news (September 2024) it will come with a detachable coax-type external RF antenna which can be replaced by the user with a different antenna model (longer cable for longer distance of antenna location, higher antenna gain etc.)

(the WebUI for the SD card looks exactly the same for the GW3000 as for the WS6210 - only the WS6210 YYYYMMZ.CSV file contains two extra battery related values)

The GW3000 comes with three LED lamps (left to right)

1. RF reception
2. network activity
3. SD card status and activity

on the backside there are four connectors/holes available
(from left to right)

1. LAN/Ethernet socket
2. power socket (USB-C)
3. SD card socket
4. reset button (above the SD card port)

the USB-C port is for power supply only - no data connection - it's compliant with the new EU regulations for a unified charging/power connectors for electronic devices.



























GW3000 manual

the structure, headers, data sequence and naming convention of the data storage CSV files (GW3000, WS6210) are:
(structure and name change logic is different from the SD card handling of the HP25x0 data)

there are two files with the naming YYYYMMZ.CSV and YYYYMMAllSensors_Z.CSV
YYYY=year e.g. 2024 MM=month e.g. 09 (September) and Z=A, B, C, ….
whenever a unit (like m/s –> km/h, °F –> °C etc.) is changed, a new set of files is created and the letter Z is added up - the same applies when fields and headers are added (or removed, the latter unlikely to happen) or their sequence changed
(A –> B –> C –> D …. etc.)
e.g. when a unit change has taken place two times, there will be 6 files (in number):
(unless they have been deleted by the user in between)
YYYYMMA.CSV, YYYYMMB.CSV, YYYYMMC.CSV and YYYYMMAllSensors_A.CSV, YYYYMMAllSensors_B.CSV, YYYYMMAllSensors_C.CSV
between unit changes the letter will be kept and only year and month change every month (the year only after month 12 [December])
e.g.

• 202404A.CSV
• 202404AllSensors_A.CSV
• 202404B.CSV
• 202404AllSensors_B.CSV
• 202404C.CSV

• 202405C.CSV
• 202406AllSensors_C.CSV
• 202406C.CSV
• 202406AllSensors_C.CSV

the YYYYMMZ.CSV files contain only the basic sensor data: outdoor/indoor T/RH, wind, pressure, solar, UV, rain
(a WS6210 has in addition the battery voltage and the external power supply voltage)

there is an entry for all possible sensors, registered or not
if a sensor doesn't exist or an existing one doesn't provide a value, “–” will be put.

The WH2600 or ObserverIP 1.0 was the first displayless console (“gateway”) manufactured by FineOffset and sold via many different resellers. The concept experienced a significant functional upgrade with the GW100 and the WH2650 WLAN version of the gateway.
The GW2000/3000 and the Ambient Observer IP2 and IP3 models now come with both LAN and WLAN interfaces
The evolution roadmap was LAN –> WLAN –> LAN + WLAN

The ObserverIP module is a small network device based on an ASIX microcontroller. The microcontroller contains the Ethernet PHY, flash, RAM and TCP/IP acceleration, and interfaces with the onboard radio receiver to obtain data from the indoor and outdoor sensors. It is compatible with the Ambient WS-1000/WS-1002 outdoor array (Ecowitt WH24 - the “boat”) used in the Ambient WS-1200, WS-1400, WS-1000-WiFi and WS-1001-WiFi packages as well as with the WH65 outdoor array. This array transmits in its Ambient version at 915 MHz (868 MHz versions also available under different brand names like Renkforce WH2600) with a 100 m maximum range via line of sight.

It comes with an Ethernet LAN interface.

It is not to be confused with the more modern WH2650 WiFi edition or even the WH2682 (Ambient ObserverIP 2.0) which at first glance look very much alike.

Still today (March 2024) some vendors try to sell this shelf-warmer “Middle-Age” piece to innocent weather station newbees.
—————————————————————————————————————————————————————————————————

The WH2650 is so-to-say a GW1000 in a different design. Instead of the wired T/H sensor, a wireless WH32B is supplied, which can be positioned anywhere and independently of the base. The device shares the identical firmware with the GW1000 - so it also behaves accordingly.

A display is also missing here. API capability and access to real-time data via the WS View or WS View Plus app (>= 2.0.30) for the WS90 are provided. This station can also work with all available sensors.

Interestingly, Ecowitt itself does not offer this Fine Offset device - so it is currently only available from resellers (such as Froggit or Steinberg) or directly from Fine Offset as WH2680 (enquire by email).

Basically, the WH2650-WiFi is an upgraded WH2600 (ObserverIP), which only enables a LAN connection [there are still remaining devices on offer, e.g. Renkforce 2600] and is (was) limited to receiving the basic sensors wind, rain, temperature/humidity/air pressure and solar. Now available for all currently available Ecowitt sensors and with WLAN (“WiFi”) interface instead of LAN (Ethernet).

Basically, the WH2650-WiFi is an upgraded WH2600 (ObserverIP), which only provided a LAN connection [there are still residual devices available, e.g. Renkforce 2600] and is (was) limited to receiving the basic sensors wind, rain, temperature/humidity/air pressure and solar. Now, as the WH2650, it is available for all currently available Ecowitt sensors and with WLAN (“WiFi”) interface instead of LAN (Ethernet) except for the IoT sensors.

In the USA, FineOffset/Ecowitt distributes via Ambient a successor to the ObserverIP “module” (console/gateway, 915 MHz), the ObserverIP 2.0 module or WH2682 console/gateway, which can receive all currently available Ambient sensors and has both a LAN and a WLAN interface as well as a WebUI (the same as a GW2000). Like all Ambient consoles, these are set via firmware so that they cannot process Ecowitt sensors (Ambient distribution policy), whereas Ecowitt (clone) consoles can also receive and process Ambient sensors. Basically, the WH2682 (ObserverIP 2.0) is a variant of a GW2000 reduced to ambient sensors and packed into the ObserverIP shell.

Froggit: WH2600Pro WIFI

————————————————————————————————————————————————————————————————-

The WH2682 (so far 915 MHz only) is so-to-say the Ambient version of the GW2000, however with all the general restrictions which apply to Ambient consoles (i.e. the cannot process signals from Ecowitt sensors - exception is the WH32 outdoor which Ambient has depreciated and likely (to-be-confirmed) an Ecowitt WH32B/WN32P TH&P indoor sensor).

the WH2882 has a WLAN and a LAN interface and can be configured via its WebUI (https://IP-address-WH2682).
if it can also be configured with the WS View Plus app or the awnet app (the Ambient version of the old WS View app) also has to be found out.

With version 2.0.48 of WS View Plus the WH2682/ObserverIP 2.0 Hub can (still) be configured and the live data can be viewed. However, as per Ecowitt, this is sort of a negligence from their part as this was not a feature request from Ambient. Hence this may get disabled in future WSV+ versions.

Like the WH2650 it has no inbuilt sensors. This means that it needs a separate T&HP sensor (WH32B/WN32P/WH32 indoor) to provide indoor Temp/Hum and air pressure data. For outdoor arrays it is limited to the three available arrays (Ambient versions of the WN67, WS69/WH65 and the WS80). All Ambient extra sensors can be received and processed.

While the Ethernet/LAN interface can be given a static IP address, this is not (yet ?) possible for the WLAN interface (“WiFi”) [firmware version 2.2.6]

WebUI of the WH2682 / ObserverIP 2.0

————————————————————————————————————————————————————————————————-

Since about May/June 2024 Ambient offers the new design Weather Hub 3.0 as the successor of the Observer IP 2.0 module/Weather Hub 2.0 - the black box in the legacy of the Observer IP 1.0 module.
Another name is Ambient Weather Network Hub IP3.

While Ecowitt in the redesign of its GW2000, the new GW3000, went back from the saucer design to a matchbox design, Ambient chose to make the saucer grow vertically and ended up with a cylindric shape. Like the Ecowitt GW3000 it also comes with a micro SD card slot - whose existence, functionality and use is completely omitted in the otherwise meticulous manual (September 2024).
When asking support@ambientweather.com, the following reply (excerpt) was provided:

“I do apologize for the inconvenience, we are working on updating our user manuals for this exciting new product! The SD slot can hold a memory card and write data directly from your weather station and additional compatible sensors.

This data can be collected at intervals between 1-240 minutes (4 hours), and is saved in a CSV format. The data writing intervals and other settings are accessible through the Weather Hub's web GUI.”

The SD card can be filled with the console data (observations and deduced calculations) in a freely selectable interval from 1 - 240 minutes in the WebUI as a CSV file. 0 = no data archiving. Also, the data can be downloaded via the WebUI.

The SD card type can be SDXC - therefore, also higher capacities are possible. Even though to fill a 32 GB SD card with sensor data (all possible sensors and their maximum number) will take about a decade.

The supported sensors are all Ambient branded sensors.

The structure and naming rules of the CSV files are the same as with the Ecowitt WS6210 and GW3000.

The WebUI looks the same as the WH2682/ObserverIP 2.0 module described above - plus a menu item for the SD card management.

For an example see below with the WS6210 WebUI. There the SD card management page is shown which is the same for the Ambient Weather Network Hub - only that the WS6210 and the GW3000 will save all available sensor data without the Ambient restrictions.

The WS6006 is the console of a 3G/4G weather station.
The use case scenario are locations where neither external power supply nor Wifi connectivity would be available and the only means for communication would be the mobile 3G/4G network. Therefore the console comes with rechargeable batteries and one or two solar panels for power supply.
A permanent power supply via USB is also possible.

The original setup was the console plus an inddor sensor plus the WS69 outdoor array - and one or two solar panels for power supply (charging the inbuilt rechargeable batteries for operation during the night and/or during periods of low solar exposition.


Meanwhile the console also supports a WS80 6-in-1 sensor array and a WH40 rain gauge instead of a WS69.
In both cases an additional WH32 outdoor T/RH sensor, one WH51 soil moisture sensor, one WN34 temperature sensor, one WN35 leaf wetness sensor and a WH41 PM2.5 air quality sensor can be added.
Pre-requisite: firmware >= 1.1.32 (see also max sensors per console matrix)


special features, restrictions and tips

• PC software (USB connection)
• Sends alarm messages via SMS
• data is saved as CSV file on the SD card
• transmission span time via WCDMA network is programmable by user from 10 minutes to 24 hours (or switched off)

Pushes sensor data to cloud weather services:

• https://www.ecowitt.net
• https://www.wunderground.com
• https://www.weathercloud.com/
• https://www.wow.com
• one custom site using Wunderground protocol only (Ecowitt protocol not supported !)

for the transmission into the mobile network to work, the SIM card must not have a PIN set


The general setup is depicted in the following picture

The WS6210 is the successor model of the WS6006 3G/4G console.
the gateway has been released in September 2024 and comes with a very comprehensive manual.

features

• 3G/4G but no 5G support
• Ecowitt protocol for custom server supported (WS6006 has WU protocol only)
• reduced posting interval restrictions: 0, 1, 2, 3, 4, 5, 10 minutes selectable
• all outdoor sensors and arrays supported
  (WS6006 has WS69 and WS80+WH40 only, + one WH34, WN35, WH41, WH51 each)
  (there is no restriction in numbers per sensor other than with e.g. a GW2000 gateway)
• all IoT sensors supported
• SD card > 32 GB supported (SDXC)

The console has the usual gateway (“AP” - access point) with the SSID WS6210x-WIFIxxxx and the IP address 192.168.4.1 inside its local WLAN - and it can also be connected to a local network router, where the location/use case allows.

The gateway will have three working modes:
1. 4G only
2. WLAN/WiFi only
3. WLAN/WiFi with 4G fall-back option

Gateway-sensor combinations (station models, station kits) will be sold under the model brand name WittField

Its WebUI looks like this:


for the structure and the naming rules of he CVS files follow this link

even with no local WiFi network available, data can be retrieved via the inbuilt WLAN/Access point when close to the console with a WiFi-enabled device (laptop, smartphone, …)

typical use cases would be remote station locations which are out of reach of WLAN access points (countryside, agriculatural areas, small airports [e.g. near runways], boats …)

as a station design proposal (agricultural use case) a model consisting of T/RH outdoor, rain, and solar/wind sensor (mounted on a provided tripod if ordered) are offered - example:

there are also configuration options with a WS80 or WS90 array including building your own station from the components as usual.

a peep into the SensorsID page of the WebUI doesn't indicate any sensor type or number restrictions compared to a GW1200 or GW2000.




WS6210 inside

the WS6210 comes with a 3-month-free (300 MB total data volume) SIM card of a provider in the ordering country (or as agreed with Ecowitt sales at the order process) and an 8 GB micro SD card. The SIM card can be extended or a personal SIM card with a provider of the customer's choice can be used.
The SD card can be exchanged with a piece of different storage capacity SDHC/SDXC type, FAT32 formatted.
For SD card > 32 GB Ecowitt recommends to use the public domain tool Rufus for FAT32 formatting (max size of a FAT32 partition is 2 TB): Rufus Tool
How many Megabytes does one post per minute generate per month ?
the post string of a GW2000 with rain and piezo, 7 WH31, 6 WH51, 2 WN34, 2 WH41, 1 WH55, 1 WN35, 1 WH45 and 1 WH57 has a size of about 2 kBytes (exactly 1,954 bytes) =⇒ 2 x 60 x 24 x 31 = 89,280 kbytes (~ 87 MB) - you can add about 30 bytes per additional sensor per post.
With the maximum number of sensors connected and a post every minute, a data usage of about 130 MBytes would be generated.

There are also eight (8) 2400 mAh rechargeable batteries included and a USB charging cable (70 cm / 2.3 ft long).
The connection cable for the solar panel is 50 cm/ 1.6 ft long.
No power supply is provided - a power supply (5 V / min 1 A) has to be provided by the customer.
We recommend using a stable (usually not the cheapest models) power supply as unstable power supplies are a known cause for console/gateway malfunctioning.
the latest firmware 1.0.5 puts the gateway into sleeping mode once the voltage goes below 4.5 V to protect the batteries from over-discharge and potential short circuit.


In a test on batteries only and WiFi on with a one minute posting interval to ecowitt.net and a local custom server post (but AP off), four 1200 mAh batteries hold for about hours. With sufficient solar exposure the solar panel can delay reaching the stand-by mode threshold. With the full install ( 8 x 2400 mAh batteries) the time before going into stand-by can be extended by 24 hours in such a setup. Running on 4G only with a 5 or 10-minute posting it would probably run for a month or longer depending on season and solar exposure during the day.

































typical scenarios - outdoor and indoor with 4G fall-back option





another hybrid (WLAN/4G) scenario would be the WS6210 gateway located outdoors but within the range of a 2.4 GHz WLAN access point.

for the time being - out of security concerns - connected IoT devices can only be configured and managed with the Ecowitt app (WSV+ to follow) but not via the WebUI

also known as Ambient WS-1000/1001/1002, Froggit 1000SE, Fine Offset HP1000/1001/1002/1003



The HP1000 series is the pre-decessor series of the HP25x0 series and is already WLAN enabled.
There are different versions of the HP1000 console.
One with 39 MB memory and one with 4 GB (3826 MB).
The latter runs on WindowsCE.
Some of the WH24 outdoor arrays (“boat”) have an inbuilt lightning detector (WH60) which can be switched on or off for console display. A lot of the configuration takes still place (or can also take place) via configuration files which are transferred with a firmware upgrade.
Some stations were sold with the more modern WH65 outdoor array.
As the identifier and transmission protocol for the WH24 and the WH65/WS69 are the same, they can be interchangeably used.

the last available firmware for the 4 GB model can be found here
the console management software here.

————————————————————————————————————————————————————————————————-

this is the predecessor model of the WS2320

the data retrieval and display software can be found here: weathersmart_setup1.9.4_0530_.zip

————————————————————————————————————————————————————————————————-

Probably the oldest WiFi-enabled console/weather station in the programme. Only the outdoor sensor group or unit (array) WH65 (Y-shape) / WS69 (I-shape) is supported as sensors.

However, the data can also be accessed remotely via WLAN using the Windows software WeatherSmart for WiFi or WeatherSmartIP. This saves the data locally in an MS Access database at the selected interval (16s, 30s, 1 min, 5 min, ….) and displays it in a window (PC interface).

The console itself can store approx. 3500 data records (one data record per selected interval) internally; if the memory is full, the oldest data record is overwritten, i.e. the software does not have to run 24/7 in order to store the data on the PC without gaps. The missing data is read from the console and transferred to the database when the programme is restarted. It should be noted that these 3500 data records with a storage interval of 30 seconds are only sufficient for just over a day. Even with a 3-minute interval, the 3500 data records are only sufficient for just over a week. And even with a storage interval of 300 seconds (5 minutes), the station can only record data for just over 12 days without the first measured values being overwritten. The console and PC interface are updated every 16 seconds. The data can be displayed as graphs or tables and exported as CSV files or JPEG files.

The console has a 5V power supply and a battery backup. It is the largest console in terms of screen size. The screen format is 4:3. This station no longer requires a USB interface (WiFi!) and therefore no longer has one.

A question sometimes asked - what does this little rain cloud icon mean and why is it sometimes blinking?

In the bottom left corner of the rain tile of the display a lttle cloud with rain drops appears when a rain event (definition –> WH40) is still going on. (Left of the period indicator: day, week, month … if you are in rain period view). In case of expected storm conditions, this cloud icon starts blinking.

Froggit: WH4000SE

————————————————————————————————————————————————————————————————-

This is probably the by far most sold Fine Offset manufactured console (and station) model, which can be found under a host of model names.

Unfortunately, this console/station does not support all current (2023) sensors and - unlike the HP2551C - does NOT have a slot for an SD card.

From device firmware V2.1.9 on (Attention! device firmware is not updateable!) up to 8 WH31 and 2 WH41/WH43 are accepted and also forwarded to external services, but these are not displayed on the console screen.

To clarify this again: For the WH2910 to be able to transmit the values of the additional 8 WH31 and 2 WH41/WH43, the device firmware must be >= v2.1.9. However, it is not possible to upgrade from an earlier (lower) firmware version to 2.1.9!

The current version of the device firmware is displayed at the top left when the console is started. In the example image, this is the device firmware v2.1.13, which supports the extended sensors.
Firmware version display of WH2910

In addition to the device firmware that cannot be updated (see above), there is also a WIFI firmware that can be updated via WS View. This app can also display the current WIFI version (EasyWeather vX.YY).

The Ambient WS-2902D console has already a new WiFi modem and firmware (AMBWeatherPro analogous to the Ecowitt EasyWeatherPro) with an inbuilt webserver page which can be reached either via 192.168.4.1 when connected to the local WLAN of the console (SSID: AMBWeatherPro-xxxxxx) or, once the pairing is established, via a web browser to the IP address of the console (http://IP-address-of-console). Posting to weather networks is via this WebUI. Posting to WU (wunderground) can only be made using the customized server functionality.

History of Ambient WS-2902 consoles and last letter meaning

Froggit: WH3000SE

————————————————————————————————————————————————————————————————-

Note:
the Ambient WS-2000, WS-4000, WS-5000 consoles are technically the same console. The only difference is the Ambient product name. They can all receive the same Ambient sensor arrays (WS-2000/4000/5000-ARRAY) and sensors. The difference comes from the Ambient sales policy only to sell console/sensor bundles and to force users with a wish to upgrade into buying also a new console.

there are still differences - see differences Ambient WS-2000/4000/5000 and Ecowitt HP25x0 consoles

The HP2551 station is sold by Ecowitt with the HP2551C console and the standard WH65/WS69 sensor array. The same console is offered with individual sensors WH40 (rain gauge) and the ultrasonic anemometer WS80 as a bundle as HP2553 station. Neither indoor temperature, humidity nor air pressure sensors are installed. Instead, the device is supplied with a 3-in-1 WH32B or WH32 indoor sensor (temperature, humidity, air pressure - also called T&HP), which can be positioned anywhere in the room without cables. The HP2551C console measures 19.5cm x 13.7cm and has a display area (TFT) of 15.5cm x 8.7cm. It can be read out via the PC weather station software Wswin using the wswin_x-csv_hp2550.

There are two different firmware updates for this console (as well as for the other consoles with a display screen), which must be installed in different ways. The device firmware user.bin or factory.bin must be imported via microSD card (SDHC, max. 32GB, FAT32). To do this, copy this file to the root directory of the microSD card using an SD card reader and insert the card back into the station. This automatically recognises a newer version and imports it from the SD card, deletes the file on the SD card (Attention! The factory.bin is NOT automatically deleted and must be deleted by the user if necessary) and restarts the device.

With v1.7.3 of this firmware from June 2021 there is - in addition to an adaptation of the translation into German - the possibility of naming all sensors yourself. Since the way to do this is not described in the original manual, here is a quick guide:

from the main view, press the button with the up/down arrow 4 times since firmware 1.7.8, the way to get there has been changed ; now it is Gear → More [Settings] → Sensor names & data - this takes you to the sensor overview then navigate to the individual sensors using the cursor keys The name can then be edited using the magnifying glass “-” [(-)].

The current device firmware can be found at Ecowitt under Manual & Software on the HP2551 and HP2553 pages. Froggit usually offers the firmware version for the HP1000SE Pro with a slight time delay. However, as both firmware versions are identical (Froggit uses the original firmware from Ecowitt), you can also install the firmware for the HP2551C and thus gain some time. The same applies for the Ambient versions of the HP2550 console, the Ambient WS-2000/WS-4000/WS-5000.

There is also a WIFI firmware that is automatically found and installed by the WS View app (Android, iOS). It is therefore worth starting this app from time to time to check whether an update is available.

Firmware updates enable new sensors to be processed and any errors to be rectified or functions to be extended. Firmware updates are therefore highly recommended (even if you don't necessarily have to be the first). However, Ecowitt is now considering the use of an (external) beta group to test new firmware versions.

A detailed description of the (possible) displays on the console main page can be found can be found below. firmware upgrade

In the meantime (April 2022) Ecowitt has released the successor model, HP2560. Apart from changes in the design (legs instead of fold-out support and fold-out internal sensor for temperature and humidity; air pressure sensor on the circuit board), which are certainly a matter of taste, there do not seem to be any other functional changes apart from the no longer existing possibility of separating the console location and the internal temperature/humidity/air pressure sensor, which some will certainly miss. Some speak ironically of an HP2550 on stilts and with a flagpole. Whilst the screen is the same size, the frame has been reduced in size. See comparison photo. See also note below at WH32B/WH32 indoor. The “stilts” are a holder from which the actual console body can be removed or into which it can be pushed. Like the HP2550, the HP2560 also has a “stilt” on the back.

With the latest firmware version, a separate, remote T&HP indoor sensor (temperature/humidity/air pressure), the WH32 indoor/WN32P sensor which also the HP2550 console uses, can also be used again with the HP2560 console (Froggit HP2000), but only with a hardware intervention. To do this, the four wires leading from the T/RH sensor (“antenna”) to the main board must be “clipped”, i.e. either cut off (pliers) or desoldered. When using pliers, it is advisable to cut the wires as close as possible to the main circuit board. If the firmware does not find an indoor T/RH sensor, it will allow a WH32B (indoor) sensor to be registered as an alternative. This has been confirmed by Ecowitt and also successfully carried out by a wxforum.net user. Such an intervention naturally leads to the loss of warranty claims in the first year, at least with Froggit. Ecowitt is not so rigid here, unless there was recognisable damage to the inner workings of the console during the intervention. With the necessary care, however, this should not happen.

Menwhile (August 2024) the separate T&HP sensor option is also available for the HP2560 console. With device firmware 1.9.5 the hardware intervention is no longer necessary and a separate T&HP sensor can be registered to a HP2560 console.

The HP2560 and also newer HP2551 models have a new, different WLAN/WiFi modem than the HP2551. Therefore, it also requires its own WiFi firmware (EasyWeatherPro - see firmware below). Together with the new firmware, the configuration of the weather services can also be accessed via a browser. A firmware update of the WIFI firmware can now also be carried out via the WebUI.
However, there is no display of the current measured values (live data) or access via http API as with other consoles (GW1100, GW2000, WN1980C). The newer HP2551 clone consoles supplied by Froggit (HP1000SE Pro) already have the new WiFi modem hardware and the new WiFi firmware as well as a WebUI. In the long term, there should be a standardised WiFi firmware again, which will then be called EasyWeatherPro for all consoles that have separate WiFi firmware. We will certainly know more soon and will be able to update this section.

Data access/retrieval
The HP2551C unfortunately lacks a mechanism to access the stored data remotely. Other stations offer a USB interface for this (such as the HP3501) or allow access via the network (such as the WH2320). The HP2551C does not support this! The HP2551C also has a USB interface. However, this is probably only intended for internal use with Fine Offset. And of course this console is accessible via network. However, it does not support data retrieval, but only the setting of data transmission to weather networks and a self-selected (customized) server.

By inserting a microSD card (SDHC, max. 32GB, Fat32) and configuring the station accordingly, the HP2551C can save all data as a CSV on the SD card at a configurable interval. According to current calculations with the CSV files available from a HP2551C and several sensors at a storage interval of 60 seconds, one gets approx. 20 MByte of CSV data per month. That's 240 MBytes per year; so 8 GB should be enough for at least 30 years.

Here too, however, there is no way to access this data remotely. So you have to remove the SD card from the station and only THEN can you access the data stored on the SD card, for example using an SD card reader.

However, you can define a destination to which the station console automatically sends the current data at configurable intervals. (see Custom Server below) This destination can also be local - but requires a remote server that receives and processes this data 24/7. Technically, the station sends the current data record in ASCII via http/POST. The destination can be a webhost server with a specially created PHP script.
However, there are also more comprehensive software solutions that have a much wider range of functions in addition to CSV generation, such as weewx, CumulusMX, Meteobridge or FOSHKplugin.

You cannot query the data. But you can retrieve the data via SD card or have it posted to a choosen target address (customized server) at intervals.

In case of a defective console display, see also HP2550 console display repair

Remember: Ambient consoles can only receive Ambient branded sensors - Ecowitt (and clone) consoles can receive sensors of all brands.

permanent automatic sea level pressure adjustment

from device firmware 2.0.0 on the normalized sea level pressure (REL) will be calculated by the console and updated whenever either the outdoor temperature, humidity or the local station pressure (ABS) change.
you will have to enter your barometer altitude for this
(Altitude = ground elevation plus height of the barometric sensor above ground)

the automatic SLP update feature with device firmware 2.0.0 has also been tested on Ambient WS-2000/4000/5000 consoles and works there also - the REL pressure field is repurposed to an altitude field

the main display/interface of the HP2550/2551 console and the 2nd generation HP2560 console
(also Ambient WS-2000, WS-4000, WS-5000 consoles - for sensors see translation table)
13. A red (!) symbol indicates that a set alarm was triggered for the respective sensor
14. For each sensor there is a red battery symbol, which is invisible in normal operation and appears to the left of the reception display of the relevant sensor when the battery is lowap pears to the left of the reception display of the relevant sensor.

since device firmware 1.9.5 when the rainfall priority is set to piezo, the text “Piezo” appears under the “Daily Rain” text.

In addition to (1): the WU and Ecowitt icons are shown in the picture as examples - two more weather service icons are possible: WeatherCloud and WOW - (shown will be the one(s) that have been set up in the console and where successful data posting is going on)
In addition to (5): for the definition of a rain event, see the WH40 Rain gauge
(3) with console firmware 1.7.6 the time stamp of the last strike is now maintained over a reboot or restart
(before it would disappear after a reboot/restart of the console)
(5) the console does not show 24h rain [yet] (=rainfall during the previous 24 h - not to be confused with 24 h/daily total rainfall)
Next (left) to the reception quality symbol of each sensor is a low-battery warning symbol, which is invisible during normal operation. It will appear only when the battery power has dropped too much.

the colour coding of the temperature display
(outdoor big circle left - indoor and extra temperatures smaller circle right)

temperature °F	temperature °C	colour	temperature °F	temperature °C	colour
< 10	< -23.3		50 - 60	10.1 - 15.6
-10 to 0	-23.3 to -17.8		60 - 70	15.7 - 21.1
0 to 10	-17.7 to -12.3		70 - 80	21.2 - 26.7
10-20	-12.2 to -6.6		80 - 90	26.8 - 32.2
20-30	-6.7 to -1.1		90 - 100	32.3 - 37.8

40-50	4.5 - 10.0		> 110	> 43.3

There are three different colours for the alarm symbol:
- red if a maximum value has been activated,
- blue if a minimum value has been activated and
- yellow if maximum and minimum values have been activated.
If the maximum value is exceeded or the minimum value is undershot, the symbol flashes and a beep sounds, which stops when any button is pressed. The alarm symbol continues to flash until the threshold values are reached again. However, the alarm is also displayed for sensors in the right-hand temperature circle if a temperature sensor other than the indoor temperature sensor is displayed (in the cycling mode display).
No alarm can be set for the WH31 and WH45.

the general time alarm symbol (!) is shown between the year of the actual date and the time

10-minute average wind speed display
the HP25x0 console is the only Ecowitt console to display the 10-minute average wind speed. (see picture above, display description, section 8).
with device firmware 1.9.9 the algorithm has been changed to comply with WMO recommendations:
sum over the wind speed values per transmission / number of transmissions in the past 10 minutes
v_average = (x₁ + x₂ + x₃ + x₄ + …. + x_n)/n
(the transmission interval for a WS68/69 is 16 seconds, for a WS85/90 8.8 seconds and for a WS80 4.75 seconds)

saving/archiving historic data (memory, SD card)
the HP25x0 consoles saves every x minutes the basic weather data (wind, rain, outdoor and indoor temperature/humidity, solar, UV, pressure) to its memory. Extra sensor data are not stored in the memory. Once the 16 MB memory is full, the oldest record will be overwritten. The archiving interval is by default every five minutes and cn be changed on the Setup page (interval) to values between 1 and 240 minutes (4 hours).
When a SD card is inserted, the basic data plus all sensor data will be written to the SD card in the archiving interval.
When a factory reset is performed, all data in the console memory will be deleted. The data on the SD card will remain untouched.
For more details see SD card management

Console power consumption
According to our own measurements, the HP2551C (old revision - without WebUI) requires approx. 500mA in operation with display and approx. 200mA when the display is switched off.


Improving the reception quality

There are sometimes complaints that certain sensors are not or only sporadically displayed in the HP25x0 console, depending on the distance and obstacles. Changing the location of the console and bringing it into the line-of-sight with the sensors often helps. However, especially with the WH51/WH31SM sensors this may not suffice.
The lack of reception often has to do not only with the console location alone but also with the built-in antenna. This is laid horizontally (a “simple” red wire 1/2 the length of the wavelength (433, 868, 915 MHz depending on the region model)). Vertical alignment usually brings a significant improvement. This does not require soldering, but simply laying the antenna in existing brackets on the inside edge of the housing. An example can be found at http://www.wetterstationsforum.info/viewtopic.php?t=1539 (in German language, use https://www.deepl.com for accurate translation).

However, this only works with an HP2550 or WS2910 console.

The HP2560 has a different interior and the antenna is installed in an elongated plastic block.

If this is not sufficient, the wire can also be routed to the outside at the top left (display view) (drill hole) and terminated with a tiltable LTE antenna. In this case, however, minimal soldering is required. Example (English): https://www.wxforum.net/index.php?topic=40585.0 With an HP2560, the LTE antenna would have to be connected to the ANT1 contacts on the mainboard (see image below right).

The CR2032 button cell is not for backup but to keep the real-time clock (RTC) alive. When it expires, the date/time is reset to 01-Jan-1070.

Reseller name: Froggit: HP1000SE Pro, DP2000 (=EW HP2560)
Froggit ships since January 2023 the second hardware revision of the HP2551 (Froggit HP1000Pro SE) console with device firmware 1.7.8 and WiFi firmware EasyWeatherPro 5.0.2;
GARNI has the HP2550 console as part of their Arcus 3055 (HP2553) station (with old and new WiFi modem)

———————————————————————————————————————————————————————————-

As the console firmware update to V1.7.3 in quite a few cases purged the name of the indoor temperature/humidity sensor shown on the main display and replaced it with the text “WH32”, the question arose how to fix this. Below the answer which is somewhat tricky and not clearly documented in the HP2551/2553 manual. On the main setup pages (pressing the wheel/gear button 1-4 times - the position changes on the 1st setup page !! - or “More [setup]” on the 1st setup page) you only find the possibility to change the display names of your WH31 extra sensors (1st setup page).

Ecowitt somehow considers the WH32B sensor, the indoor temperature/humidity/pressure not as a basic sensor (what common sense would expect as the sensor comes with the HP2551/2553 packages) but as an OPTIONAL sensor. Hence you have to look somewhere else: on the “Optional Sensor Display Mode” page ( press 4 x ▼▲ from the main display). There you suddenly find your WH32B T/H/P sensor under the name it shows on the main display. However the example in the manual does NOT show this sensor …. On this page the display names of all sensors shown (all optional sensors including the WH32B) can be edited. Select the sensor with the ▼▲ key and press the (-) key to enter the editing dialogue.
From firmware 1.7.8 on this page was moved into the “settings” area: Settings (gear wheel) –> More [Setup] –> Sensors Name&Data
(but you can still reach it via pressing 4 x ▼▲ from the main display )

The sensors ID submenu is not properly described in the HP2551 manual (October 2021) and people trying to install a WH32B (e.g. for the HP251 or the WH2650) or the WH32(-EP) - the WH32 manual only shows how to get a WH32 installed for a GW1000/WH2650 but not for a HP2550 console where WS View only works for weather network configuration - are confronted with obstacles, I have decided to explain the SensorsID submenu below.
How to get to the sensor ID sub-menu page
Setup (gear wheel) –> More [setup] –> SensorsID

By the way - there are two submenu pages for the Sensor IDs. The 2nd one is found by pressing the arrow-right.on-a-page key (4th key from the left) when you are on the 1st SensorIDs page. The 2nd is for the WN34 and WN35 sensors, whereas the rest of possible sensors shows on sensorIDs page #1.

It's a table with three main columns, each of which has three resp. four sub-columns.
the below pictures represents device firmware 1.9.6

the little USB-A icon means that the AQIN sensor (WH45/46/46D) is powered via a DC adapter



GARNI in Europe have given own sensor names also inside the HP2550 console (their name: Aercus 3055) and do not show the WS68 and WS90 sensors

below the SensorsID page of an Ambient WS-2000/WS-4000/WS-5000 console on device firmware 1.9.6


comparative table of sensor acronyms on the HP25x0 sensorID page across resellers

Ambient has only two PM2.5 AQ sensors (WH41/43) where #1 is predefined as outdoor (WH41) and #2 as indoor (WH43). The number of Water Leak (WH55), extra T&H (WH31/WH31E), and Soil Moisture (WH51/WH31SM) are the same: 4, 8, 8.
With Ambient it is either a PM2.5 indoor or a 5-in-1 AQUIN (WH45/46) combo sensor. Both can be registered separately in either the AQIN or IN PM2.5 sensor ID field, but only one will work - as they share the same channel.
So, you either register an PM2.5 sensor as indoor sensor (IN PM25) or an AQIN combo as AQIN.

the table is quite self-explanatory, except for the 1st main column where you find the “T&HP” and “T&H” entries. T&HP is the WH32B sensor - the indoor temperature/humidity/air pressure sensor T&H is the WH32 sensor - the single temp/hum outdoor sensor (all other outdoor T/H sensors are integrated in one of the three outdoor arrays, WH65, WS68, WS80, WS90 and are reported via them) - if you use an outdoor array and a WH32(-EP) outdoor T/H sensor in parallel, you will to register it here - and its readings will override the outdoor T/H readings of all the other arrays (–> Sensor Hierarchy).

The WH57 lightning detector and the WH45/WH46 indoor 5-in-1/7-in-1 air quality combo sensor also show in the first column.
The same with the WH65/WS69, WS68, WS80 and WS80 outdoor arrays.

In order to either register or deactivate a sensor, you will have to select its ID field with the up/down arrow keys and then press the (-) key.
A little pop-up window appears where you have five options:
1. Register (the console will automatically look for the sensor);
2. enter its ID and register it actively (this is useful if you have sensors of the same type and are not happy with the console's choice - or want to assign a particular sensor to a channel (see WH41/43, WH51, WH55, WH31/WN30));
3. select “disable” to deactivate the sensor
4. save (always needed except for 5.)
5. cancel

It is generally GOOD PRACTICE to actively DISABLE all sensors you do not use with your console (HP2550, GW1x00, WH2650) in the sensorsID section of your console or WS View Plus app in order to avoid wrong registrations. Do not leave the sensor ID entry in “learning” mode.
Battery exchange - Battery replacement
If you change/replace the batteries of your sensor(s), the sensor(s) might need to be re-registered in the console(s) it was (they were) registered to before !!

The 2nd main column houses the WH41/43 PM2.5 sensors (4 channels) and the WH31/WN30 Extra Temperature/Humidity sensors (8 channels)
The 3rd main column houses the WH51 soil moisture sensors (8channels) and the WH55 water detectors (4 channels)

HP2550 and HP2560 consoles with recent WiFi firmware EasyWeatherPro only !!
(also applies to Ambient WS-2000/WS-5000 consoles with AMBWeatherPro WiFi firmware)
The WiFi firmware for the newer HP25x0 console models with the new WiFi modem (EasyWeatherPro) could already be updated over-the-air (OTA: here via WiFi) earlier EasyWeatherPro versions. With device firmware 1.9.5 this is now also possible for the device firmware. This means that no firmware upgrade via SD card is necessary anymore for the newer models.

———————————————————————————————————————————————————————————-

beyond their Proprietary foreclosure policy regarding their sensors, Ambient seems to go for the cheapest solution rather than for fully fledged functionality - see also firmware differences below

1. Ambient consoles only process and display Ambient branded sensors (exception WN32 as Ambient WH32E was decommissioned)
2. the WS-2000/4000/5000 consoles are HP2550 clones - functionalities of the HP2560 are not taken nor the HP2560 hardware used/offered
3. the temperature compensation functionality is not used (“not needed”)
4. the choice between Feels like and Apparent temperature is not offered (on the MORE page) (“not needed”)
5. the WS85 and WS58 do not appears on the Ambient SensorsID page (no related Ambient product exists)
6. no WN34 calibration (obvious, because Ambient doesn't offer homologue WN34 sensors in their variations (S/L/D)

other facts also indicate this procurement saving and selling price maximization policy. e.g. their WS-4000-ARRAY (a diet version of the WS90 without heater and external power supply)

Also their policy trying to force users to post data to Weather Underground (WU) via AWN rather than having a preset option. This preset option for WU including WeatherCloud and WOW formerly existed and was removed from the Weather Service options of an Ambient WS-2000/4000/5000 console. If one still wants to avoid the capricious behaviour of AWN regarding WU postings, one can still post to AWN via the Customized Server.

It can only be speculated that there is a profit maximization approach behind the less functional hardware choices and the reduced firmware functionality. Possibly the reduced firmware functionality was a criterion for a lower procurement price. Why would one otherwise reject an added value coming for free and making the product more attractive …

The very fact that Ambient seems to lag behind device firmware upgrades probably results from the situation that the newer firmware versions, even though compatible with the WS-2000/4000/5000 consoles, do only provide functional upgrades to Ecowitt consoles and are “not needed” by Ambient.

Closely looking there isn't any advantage visible why someone (an end user) should buy an Ambient Weather Station manufactured by FineOffset rather than an Ecowitt Weather Station. Unless one has fallen into the trap of the Ambient/Fine Offset contractual agreement granting Ambient the exclusive right to sell their WS-5000 station in the USA and disallowing Ecowitt to sell their HP2553 station or even a single WS80 into the USA.

There are of course always workarounds via neighbouring countries or via K-Town in Germany if one has the proper connections which allow for a WS80 to reach the USA without the breach of the above mentioned contract. The HP2553 or GWx003 stations are still the best (ultrasonic + traditional rain) stations Ecowitt has to offer.

If someone likes the Ambient Weather Network dashboard more than the Ecowitt dashboard, they can buy a license from Ambient and have their console MAC address connected to it. And then post to AWN using the Customized Server. Still significantly cheaper than what an Ambient station costs more than the Ecowitt version with more functionality.

———————————————————————————————————————————————————————————-

the old WH24 (Ambient WS-1001) uses a different wind measurement method and has a different funnel surface for rain readings.

While the consoles with the Ecowitt Gateway API (GW1x00, GW2000, WN19x0) have a compensation switch for a WH24 in their device settings, the HP25x0 and HP350x consoles don't.
Here one has to use different gain factors for WH24:
wind gain: 2.17, rain gain 1.18

If you want to use the new WH65/WS69 with an old WH1080 (Ambient WS-1000) console,
the gain factors are: wind gain 0.46, rain gain 0.85

————————————————————————————————————————————————————————————————-

This console a much smaller display (4.3“ - just 9.5 cm by 5.5 cm) than the other consoles. However, the advantage of this station is the USB interface, which can be used to access the stored measured values with suitable software (such as EasyWeather2). Access via USB may also be possible using software under Linux such as weewx, pywws or wfrog.

On the main screen you can see the current time and date, values of the WH57 lightning sensor, the WIFI strength, a graph of the time course of a selectable sensor, wind rose with direction, wind force and gusts, 4 water leak detectors, a soil moisture sensor (presumably channel 1) and - alternating/cycling - all values of the WH45. It also displays air pressure, UVI, solar radiation, rain rate, indoor temperature/humidity and - alternatively - outdoor temperature/humidity, dew point, Feels Like temperature and the values of the 8 possible WH31/WN30.
Except for the HP25x0 consoles, the HP350x console is the only other console to display the WH57 lightning sensor information in the top right of its display above the wind segment.

With firmware > 1.7.2 a SD card symbol with status colour appears in the top right corner of the graphical history of a chosen sensor pair when a SD card is inserted (green = normal, red = error).

An external WH32B T/H/P sensor is supplied.

The station is powered by a small plug-in power supply with a very small hollow plug (2.5×0.7mm) and 5V. If you prefer to use your own power supply, you can ensure this via a USB cable that ends in the corresponding barrel connector (e.g. AK-DC-02). There is also a USB micro socket and a microSD slot (SDHC, max. 32GB, FAT32). The station can be calibrated like a “large” one. The rain values can also be edited.

In custom server mode, the station behaves like the HP2551C - however, the 10-minute average wind speed is not calculated. The values of the WH41, WH57, WH45 etc. are all available. The only display language that can be set is English.


The console also offers the option of exporting the data via CSV using an optional microSD card, although not all sensor data is currently included in the CSVs - for example, the values for the WH57, WH45, WH55, WN34 and WN35 are missing. The CSV data format also differs from that of the HP2551C.

This console also contains two different firmware versions. To check the current firmware, proceed as follows:

Press the right button 7 times until the “Factory” overview appears then press the left button 4 times to go down to “About” Press the second button from the left (”+“) to go to the display.

There you will find the WIFI version in the 5th line and the version number of the device firmware in the 7th line. After approx. 45 seconds, the display automatically switches back to the main screen.

The WIFI firmware is updated as usual via the WSView Plus app. The device firmware is also transferred to this station via a microSD card.

The WN1900 is a low-cost station for beginners. It consists of the bundle of WN1900C - the actual console and a special sensor array, the WN67, which is powered exclusively by batteries instead of the usual solar panel and supercapacitor. A battery storage unit with a 10 metre cable is available as an accessory, which can be used to store and replace the batteries indoors if necessary (depending on the distance between the outdoor supply group and the home). It could also be used with a WS69 (I-shape), but not with a WH65 (Y-shape). At shop.ecowitt.com the array power supply extension can be found under “Accessories for WS69”.

The outdoor sensor array of this “light-weight” WH65, the WN67 (which looks like a WS69 at first glance), also has no solar sensors.
The WN1900C console has a few interesting features, such as battery buffering and support for the GW1000 API - so there is also the option of viewing live data here. Apart from that, it supports all known sensors that the GW1000 also supports. In principle, it is apparently something like a GW1000 with a display - but not all sensors are shown on the display (which is understandable due to the screen size). Nevertheless, the WN1900C could be interesting as an additional console.

The console is available (also individually, without outdoor sensor) in two versions, grey-black display [WN1900-C] or coloured-black display [WN1910-C / WN1920-C].
The WN19x0 consoles can also receive the data from a WH65 outdoor sensor group, but cannot display the solar data. However, it can receive all solar data.

The WN19x0 consoles have the local Ecowitt Gateway API, which means that
a) they can be configured with WS View Plus app and
b) live data can be displayed in the WS View Plus app.

However, it can pass all received data (even those that it cannot display) to ecowitt.net and display them there. Basically, the WN19x0 console is functionally a GW1x00 with limited display options. The fold-out “stick” is by no means the WiFi or sensor antenna, but only houses the indoor temperature and humidity sensors.

However, there are still a few “ambiguities”: Apparently, the WN1900C uses a different chip (Opulinks) from the GW1000, GW1100, GW1200 and WH2650. At least that is what the MAC address should indicate.

Despite rumours to the contrary circulating in certain forums, a WH32 can indeed be received. However, a WH32B cannot, which is not necessary as the console has built-in T/H and air pressure sensors.

Pairing with the router requires an activated 802.11 b protocol for the WLAN component of the router. With some routers this must be activated manually! An up-to-date WS View Plus app is also required so that you can select the correct console (image) to be connected to the WLAN router. For the WN1900/WN1910, this is the image with a green screen and a blue Bluetooth symbol at the top left.

The WN1900C console has a very clear, easy to read and very tidy display with a width of 8 cm and a height of 9.5 cm. The external dimensions of the console are 10.5cm wide and 11cm high. The backlight has 4 dimming levels.

Froggit offers the WN1910 (together with light-weight outdoor sensor, WN67, without solar panel and solar data) as WH3900 - the WN1900 is not offered and the WN1980 so far not yet.

Meanwhile (March 2024) the WN1910 console has been upgraded with a WebUI and the WiFI protocols 802.11 b/g/n under the name WN1920. No more Bluetooth needed for the initial pairing. The WiFi transmission distance (2.4 GHz) is 50 m /0.55 yards.

Ambient sells the WN1920 as WS-1965 with the usual Ambient console restrictions and an Ambient version of the WN67 5-in-1 outdoor sensor array (no solar panel, no light sensor): WS-1965-ARRAY. Also, the Ambient PM25IN (~ Ecowitt WH43) cannot be registered together with an Ambient AQIN sensor (~ Ecowitt WH45) - strangely it's either or and Ambient claims that their PM25IN uses the same channel as their AQIN (CO₂, PM2.5, PM10, T/RH) sensor.

During a firmware upgrade the top right tile segment which usually shows the date shows “OTA.xx” where “xx”” stands for percentage of completion. OTA stands for over-the-air and means WLAN/“WiFi” in our context.

The WN1910 console now has also got a more powerful companion, the WN1980. The display is also in colour, but shows different colours for the respective sensor values than the WN1910. In addition, it no longer uses Bluetooth for configuration but “normal” WiFI (802.11 b/g/n protocols). It also has a WebUI and the option of querying via http-API. It also no longer has buttons on the side but touch-sensitive surfaces on the display. Otherwise, the functionality is identical to the WN1900/WN1910 console.

————————————————————————————————————————————————————————————————-

The WN1980 is apparently a slightly improved WN1910. Power is supplied via a USB3-C socket. The buttons for operation have been omitted - instead, the operating elements have been designed as touch sensors in the lower area of the display.

Finally, modern WLAN standards are also supported - this was not the case with the WN1900C resp. WN1910C where the 802.11b mode had to be activated explicitly on the router/AP, the WN1980C can also handle 802.11g/n thanks to ESP32-C3. It doesn't need Bluetooth for the initial pairing with the router either.

With firmware 1.2.3, it also supports the intelligent water valve WFC01 and the intelligent (IoT) switch AC1100 (see there).

Like the WN1900/WN1910 the WN1980 has the local Ecowitt API by which live data can be display via the WS View Plus app. In addition has the WN1980 a WebUI where configuration can be made and live data can be viewed.

The raindrops on the weather forecast display flash when storm is expected to happen. This flashing does NOT indicate that it is raining. However, in the event of prolonged rain and corresponding air pressure conditions*, the two may overlap and the drops may flash when it is raining. However, this is only due to the particular situation.

Ecowitt has recently released a new console, the WN1821. Strictly speaking, it belongs to the WN19x0 series, but with a different sensor selection for the display and is more focussed on indoor climate. The WN1821 also has an inbuilt CO₂ sensor. The WN1820 does not have this, but is otherwise identical.
In the CO₂ display field at the top right of a WN1820, only the date is displayed; with a WN1821, you can change the date with the display of CO₂ readings.

Ambient sells the WN1821 with a WH31E (WH31 multi-channel) as a stand-alone weather station (WS-1938).

It displays indoor temperature/humidity as well as all sensors belonging to the WH31 family, the WN34, WN35 and WH51 sensors (automatic alternating display or manual switching). See the image on the right for what is displayed where. It does not display: Outdoor temperature and humidity*, solar/UV, wind, rain and air pressure.
(since firmware version 1.2.3 for WN1980/WN182x, outdoor temperature and humidity can be shown on the display)

Since firmware v1.2.7 (February 2024), a WH32B is also supported instead of the internal T/H/P sensor (Attention! the WH32B is activated by default and thus overrides the internal sensors if a WH32B is present).

During a firmware upgrade the top right tile segment which usually shows the date shows “OTA.xx” where “xx”” stands for percentage of completion. OTA stands for over-the-air and means WLAN/“WiFi” in our context.

Reseller models: Ambient WS-1938 (=EW WN1821)

————————————————————————————————————————————————————————————————-

The WS3800/3820/3900/3910 consoles with a relatively large LCD screen (diagonal 7.5 inches/19 cm) are available with a blue and white (WS3800), a three-colour tile display (WS3820) and a colour display: colours on black background (WS3900/WS3910). They also support the WFC01 and AC1100 IoT sensors.
The consoles both have the local Ecowitt Gateway API, i.e. the data can also be displayed in real time in the WS View Plus app or in the WebUI.
The consoles have built-in T&HP sensors, but can also use a separate WH32B/WN32P T&HP sensor as an alternative.
The display update time is specified as one minute. However, in practice, the tiles update when new data is received.
The consoles both have a battery backup with three AA batteries, which protects them against short-term power failure (provided the batteries are inserted ). Continuous operation with batteries only was tested for one hour.
With firmware upgrade 1.2.9 the WiFi is switched off when running on batteries to save energy.
Also from firmware 1.2.9 on the backlight of the display can be programmed to switch off and on at a certain time. WebUI –> Device Settings.

Another interesting observation:
the display was originally updated every eight seconds only (therefore every second transmission of a WS80 would get lost) - meanwhile it can be updated every second provided a sensor update arrives.

WS3800 (down) / WS3820 (up)




The only visible hardware difference between a WS3800 and WS3820 are the 3-colour background tiles on the display and the text on the buttons.
(white is not a colour but the sum of the spectral colours )

The WS3800 has eight buttons by which the multifunctional tiles (display areas) can be switched between the to-be-displayed values (e.g. pressure or rain, min/max values, different outdoor values like dewpoint, feels like, wind or gust, and extra temperature/humidity sensors: single or cycling). Also the background light can be dimmed in two levels or completely switched off.

(Also the configuration can be done via the SET button. In setting mode the + and - keys are used to change/toggle between values)
more details see WS3800 manual
the configuration can also be done - as usual with consoles having the local Ecowitt API, via the WS View Plus app and their WebUI. The Ecowitt app can also be used when accessing the local network for its internet access)

WS3900 / WS3910

The WS3910 differs from the WS3900 in that it also has a built-in CO₂ sensor. While the WS3800/WS3900/WS3910 can all display the CO₂ values of a WH45/WH46(D) sensor, a WS3910 console can display two CO₂ values: those from the inbuilt CO₂ sensor and the CO₂ values of a WH45/46 sensor that is e.g.located in another room. In the display, which changes at the touch of a button, the two CO₂ values can be distinguished as follows: the values originating from a WH45/46 have a small reception quality symbol in the display field, the internal values do not have this symbol.
The PM 2.5/10/1 values from a connected WH45/WH46 (D) can be displayed in the bottom left CO₂ display tile.

Note that the PM4 readings of a WH46(D) sensor and the T/RH readings of a WH45/WH46(D) sensor CANNOT be displayed on the WS3800/WS39x0 console display. All this their readings together can only be seen on a HP25x0 console or in the WS View Plus app, the ecowitt.net dashboard or in the Ecowitt app. Real-time data only on a HP25x0 console and the WS View Plus app.

The eight buttons on the top panel are used to switch between multiple display locations - There is also an auto-scroll (alternating display) mode for the outdoor temperature/humidity and WH31 Extra temperature/humidity sensors.
The WH41/43, WH51, WH55, WH57, WN34 and WN35 sensors can only be sent to the Ecowitt cloud (or via custom server) but cannot be shown on the display.
If you also want to display these values, you need either an HP25x0 console (on which the display is rather minute for these sensors) or a WN1820/1821 console. See also which sensors displayed on which console

The raindrops and clouds on the weather forecast display flash when a storm condition* is detected. This flashing does NOT indicate that it is raining. However, in the event of prolonged rain and corresponding air pressure conditions, the two may overlap and the drops may flash when it is raining. However, this is only due to the particular situation.
storm condition : a sudden barometer pressure drop for over 3 hPa over the past two hours detected.

(Incidentally, the forecast on the WN1980 also flashes - but only the raindrops there).

The main difference between a WS3800 and a WS3900 console is the screen display layout and the colour.
With the WN39x0 console you have a better overview over the actual rain day situation.
Also, the WS3900 has two rain buttons (RAIN1, RAIN2) to handle the upper and lower portion of the rainfall tile.

The WS39x0 console is the first Ecowitt display console, where you can see rain rate and daily rainfall amount clearly at the same time without having to press buttons or switches (or need to use a magnifying glass like with the HP25x0 consoles).



the rain rate bar during actual rainfall (show RATE/H) shows the highest rain rate during the actual rainfall
the rain event bar shows the accumulated rain during the time window of the rain event (show EVENT)

Illustrations: bottom WS3900 - display view and display layout - control buttons - layout examples WS3910 (with inbuilt CO₂)

during a firmware upgrade the tile in the lower left of the WS800/WS39x0 consoles (date / air quality tile, CO₂, PM …) shows
“OTA.XX” (XX = percentage of completion) - then a restart takes place

Symbols
After a restart (batteries removed, mains cable unplugged and reverse reinstallation and connection - or after a factory reset), the console starts a sensor search, which can be recognised by the flashing of the RF symbol (mini radio mast) in the individual tiles where this is provided (see display layout).

If the corresponding sensor has been found, either because its ID has already been defined or because the console has found a corresponding sensor, the bars (max. 4) for the signal quality (the last four successfully processed data packets) are also displayed for the corresponding sensor.
In the case of sensor arrays, this display takes place in the wind tile. For an external CO₂ sensor (WH45/46), this takes place in the tile at the bottom left. Built-in sensors (CO₂ for WS3910, indoor temperature/humidity and air pressure) are not displayed.
If the battery level is low or batteries are not inserted, a symbol with a half-charged battery appears in the indoor tile. The same applies to the sensors, where a battery symbol is provided in the layout. The RF symbol with bars is only permanently displayed in the rain tile if a WH40 is connected and the rainfall priority is set to traditional rain gauge.

Reseller name: Froggit WH5000

————————————————————————————————————————————————————————————————-

This is more of a “narrow-gauge console” - without reading and displaying wind, rain or sun. It displays the date and time and the current moon phase. Air pressure and a weather forecast based on air pressure history are also displayed.
Furthermore, indoor temperature and humidity and up to three additional T/RH sensors (type WH31), which can also be placed outside, are displayed under “outdoor”. Depending on the setting, these change either manually or every 2-3 seconds (cycling - alternating display). There are min and max displays for temperatures and humidity, which can be reset at midnight (all or none).

It is listed at ecowitt.com under “Thermometer”. It can be operated with up to three temperature sensors, called WH32F (which is a WH31 with DCF-77 receiver).

Power is supplied by a 6 V power supply (mains adapter) or 3 AAA batteries or both as a backup in the event of a power failure. In battery operation, the screen/display is not permanently illuminated. The signal transmission and thus updating of the outdoor temperature/humidity display takes place every 60 seconds.

Ecowitt only offers a 433 MHz model with just one sensor. In Europe, the identical model is also available under the GARNI brand, model GARNI 281, in an 868 MHz version with up to three sensors and changeable display.
Conrad also sells it as Eurochron EFWS S250, 868 MHz.

A station can be legally operated at 433 MHz in Europe. However, you then need extra sensors that transmit at 433 MHz, while the 868 MHz model can use the WH31 sensors of an existing 868 MHz sensor landscape. Alternatively, the “little man” can receive up to three classic WH31 extra temperature/humidity sensors. It is therefore perfectly suitable as a second console (“for the family” or something alike).

Or used in the bedroom without additional electrical smog from WiFi. This console is purely a receiver. The WH2810 recognises the WH31 sensors that transmit on channels 1, 2 and 7. With and without DCF receiver. With DCF receiver the time is synchronised. A WH31 with built-in DCF receiver with the confusing designation WH32F is supplied.

Attention: there are obviously two different models WH2800, Ambient WS-2800 with only one (real) WH32 sensor and WH2810, Ambient WS-2801/2801A with a maximum of three WH32F (=WH31 type) sensors.

The Ambient WS-2801 cannot cycle the temperature display of the max three WH31 type (Ambient WH31M) sensors, whereas the Ambient WS-2801A has the cycling/scrolling feature. The Ambient versions transmit at 915 MHz.

The HP3000 is not part of the official Ecowitt portfolio, however, it can be ordered on demand via the mother company Fine Offset or purchased from a reseller on your continent. The HP3000 comes as a 868 MHz and 915 MHz model. It's more of a temperature/humidity surveillance system than a real weather station.

The HP3000 monitors and graphs up to eight wireless remote sensors (WH31 extra temperature sensors) at the same time. The comprehensive data logger includes a TFT full color display with graphing and monitoring of temperature, humidity, dew point, and heat index. You can view channel 1 temperature, dew point or heat index from the display. You are also able to monitor up to 8 channels at the same time, using imperial or metric measures. This includes minimum and maximum temperature and humidity display with an easy reset option.

High and low alarms can be set for any of the measured parameters; audible and visual alarm will sound when a value is out of range. The sensor search mode allows you to re-sync sensors without removing and re-inserting batteries. Optional temperature and humidity calibration is provided for the utmost accuracy, although the measurement can be adjusted from the console to calibrate to a known source.

The HP3000 also includes PC software for data analysis, console programming, and easy data extraction from the optional micro-SD card.

In Europe the HP3000 is sold as a 868 MHz model by the reseller ELV under the brand dnt as RoomLogger Pro with a black housing.

————————————————————————————————————————————————————————————————-

the sensor arrays have several levels of power supply: solar panel, super-capacitor (sort of a rechargeable battery) and batteries (+ external power supply: WS80/WS90). Exception WN67: batteries only.

During the day with sufficient solar exposure the solar panel will run the array. If there is more power produced than needed, the super-capacitor (haptic array [capacitor] at the ecowitt.net dashboard) display for a WS90) will be charged up to 5.3 V in order to provide power duin the night and for low solar exposure. If due to unfavorable weather condition (or a defect) the super-capacitor expires, the backup batteries are used.

(the WS80 power status would be displayed as “sonic array”, the WS69 as “Sensor array”, the WS68 as “Wind Sensor”, the WS85 as “Haptic 3-in-1” - super-capacitor info is only available for a WS85 and a WS90 array)

When you have a WS80 or WS90 and have an external power supply (12V, 1A) connected, the complete array is running via the external power (plus, in winter, the heater)

————————————————————————————————————————————————————————————————-

it can happen that the outdoor array stops transmitting data - either all data or only those of some sensors
(e.g. no more temperature/humidity data but wind and solar data is still reported)

before thinking of replacing sensors or parts of the array or even the whole array, a reset may get it back working again

this applies to all Fine Offset manufactured outdoor arrays:
Ecowitt: WH65, WS69, WS68, WS80, WS85, WS90 and WH24 (legacy)
Ambient: WS-2902A,B,C,D-array, WS-2000/4000/5000-array, WH24-array (for WS-1965 array only remove batteries for hardware reset)
Froggit: WH3000SE, WH4000SE, DP1000, DP1100 (for WH3900 array just remove batteries for hardware reset)

there are two types of resets like with a computer:

1. restart or warm reset (warm because the hardware continues running)
2. shutdown and power off or cold reset (the device will be made powerless and hardware powers up again completely)

1. just means to press and hold the reset button for > 5 seconds and release (in some cases your have to insert the open end of a paper clip)
2. is more complex

• remove the batteries
• cover the solar panel tightly with black tape - or take the array to a dark room - wait until the LED stops blinking, can take up to 72 hours
• re-insert the batteries and remove the black tape if you used it

1. is also called soft(ware) reset and 2. hard(ware) reset,
because this is what is done, like the restart while still running or shutdown and new start of a computer


————————————————————————————————————————————————————————————————-

the “first” wireless (RF based) outdoor array sold by Fine Offset in the early days of private weather stations - still quite a few are running these days. It was sold with the WH1080 console, predecessor of the WS2320 console which came with a USB interface and software.

The old WH24 (Ambient WS-1000/1001/1002) uses a different wind measurement method and has a different funnel surface size for rain readings.

While the consoles with the Ecowitt Gateway API (GW1x00, GW2000, WN19x0, WS3800/WS39xx) have a compensation switch for a WH24 in their device settings, the HP25x0 and HP350x consoles don't.

Here one has to use different gain factors for WH24: wind gain: 2.17, rain gain 1.18

If you want to use the new WH65/WS69 with an old WH1080 (Ambient WS-1000) console, the gain factors are: wind gain 0.46, rain gain 0.85

the modern WiFi consoles cannot tell the difference between a WH24 and a WH65/WS69 or WN67 when receiving their signals. The firmware still identifies them internally as WH24.

—————————————————————————————————————————————————————————————————

this sensor array is available with identical technology as a 2-wing and 3-wing version. The different designs are often referred to as I (Two-Wing) shape = WS69 or Y (Three-Wing) or osprey shape = WH65. The array includes sensors for wind (speed and direction), rainfall, light (solar radiation, UVI), temperature and humidity. The solar panel contained in the sensor supplies the energy for the normal operation of the sensor and fills an internal supercapacitor, which provides the power supply overnight. The two AA batteries are only used when the capacitor's capacity is exhausted. Battery life of one to two years should therefore be possible. With the BP0001, an external battery pack is available in which the batteries are housed in a box 10 metres from the actual sensor. This allows the batteries to be changed without removing the sensor from the mast (or having to climb up).

The rain gauge of the sensor array measures in 0.254 mm³ (0.254 mm/m² precipitation) steps, which are displayed by the console as sequences of 0.2 and 0.3 mm. Therefore, there is a display error of 1.26 % or 0.04 mm in the console display. When the rain values are transmitted by the console, the values are forwarded correctly, without rounding loss, in inches.

The transmission interval is 16 seconds.

The change in design comes from the observation that with the Y-shape there is more mutual disturbance by turbulences between the cups and the direction indicator than with the I-shape.
There are also earlier versions of the WS69 (I-shape), where the cups are below and the direction arrow above (i.e. opposite to what is shown in the picture)

If you want to use a WH65/WS69 combination sensor with an old HP1080/WH1080 console, you have to change the calibration for wind and rain measurement (analogue to the WH24, see there) (as the cups rotate faster and the rain funnel surface is larger than with a WH24, for which the WH1080 console is originally programmed):
Wind gain 0.46, Rain gain 0.85 (“gain” stands for calibration factor)

Ecowitt have developed a specially protected version for the T/RH sensor of the WS80/WS90/WS69/WH65 sensor arrays to protect it against exposure to salty air (e.g. near the sea or in the vicinity of salt deserts, North/South America). This applies only to the new hardware version with plug-and-play sensor. (See picture of WS80) (Attention: due to the design, this sensor is available in two different versions for the WS90 and the other sensor arrays)

Since June 2024 the WS69 is delivered containing the salty air protection Temperature/Humidity sensor.

The WS69 should not be confused with a (n old) WH14 array which is still sold with old stations for the resellers to empty their stock of shelf-warmers. Even though it looks the same from the outside, the array cannot communicate with the modern Ecowitt consoles (or more precisely speaking the consoles do not understand the array transmissions). The WH14 uses a different modulation technique (ASK = amplitude shift keying) for the transmission from the modern consoles (which use FSK = frequency shif keying). It can only be distinguished by the array name on the underside of the housing where WH14 is shown.

there are spare parts available at https://shop.ecowitt.com for the different sensors:
- the temperature/humidity sensor (two versions for the older and new hardware revisions)
- the funnel
- the anemometer body
- the wind direction indicator (arrow)
- the wind cups
- the whole rain bucket/temp/hum portion
- the whole wind reading portion
- bird spikes for the rain funnel

the spiral offered as protection agains debris (e.g. leaves) for the WH40 can also be used in the WS69 funnel.


for the new WS69 hardware revision you can order
- a pluggable SHT40 sensor for T/RH (sold as WS80 accessory)
- a pluggable SHT35 sensor for T/RH (extra precision)
- a pluggable SHT35 sensor with sea salt protection (sold as WS80 accessory)
(attention - the salt protected sensor for the WS69/WS80 arrays is the same; the WS90 has a different size)

If the supercapacitor of the WS69/WH65 array fails, there is a simple and efficient repair option for hobbyists proposed at:

since June 2024 all new WS69 are delivered with the salt protection T/RH sensor version !

———————————————————————————————————————————————————————————-

The WN67 is a “leight-weight” version of the WS69.
It is basically a WS69 without a solar panel and without a solar sensor.
It is therefore battery-operated. There is a battery enclosure with a 10 m cable available to avoid having to take the outdoor array down from a mast (or climb up) every time the battery needs to be changed.

the enclosure can be found as a single item at https://shop.ecowitt.com under “Accessories for WS69”

The WN67 is sold as a station package together with the WN1900/WN1910 consoles. The enclosure could also be used with a WS69 (I-shape), but not with a WH65 (Y-shape) !

Froggit sell the WN67 together with the WN1910 console as WH3900 station (which now becomes a naming clash with the new Ecowitt WS3900 consoles)
The outdoor array sold with the Ambient WS-1965 is the WN67 array (no solar panel, no solar sensor).
It identifies itself as WH65. Therefore the WS-1965 console can also be used with a WH65 (WS2000-ARRAY).

the Ecowitt 5-in-1 sensor array for wind, gusts, direction, solar radiation, and UV readings.
like its siblings it has a solar panel and an inbuilt supercapacitor to store energy for the operation over night or with low solar exposure.
It has a AA type backup battery.

It is a classic cup anemometer and is meant for operation with individual sensors.

The RF transmission interval is 16.5 seconds.


reseller product name: Froggit DP300
———————————————————————————————————————————————————————————-

The 6-in-1 sensor array possesses an ultrasonic anemometer. In addition to wind speed, gust and direction, it also measures light (Solat radiation, UVI), and outdoor temperature and humidity.

The transmission interval of the array is 4.75 seconds.

Unfortunately, a battery pack is not available for this sensor (although this is hardly necessary in our Central European latitudes, apart from narrow Alpine valleys and the like, as the supercapacitor fully charged by the solar panel can operate the combined sensor for up to three days without recharging. Conditions in which sufficient recharging due to lack of solar exposure is not possible and the batteries have to be used are very rare here. This is certainly different in Northern Scandinavia or similar locations in North America or Russia with polar nights. The newer models (type 3) can also be operated entirely with an external power supply (see below). ).

However, an extra power supply unit (12 V, 1 A) with a 10 or 20 m supply cable is available as an accessory, which can be used to supply a thermostat-controlled heater that ensures operation of the ultrasonic sensor even at temperatures below freezing point. A cable with the coupling for the supply line is led out of the sensor. The external power supply for the WS80 and WS90 is identical.

with the newer WS80 models (type2 and type 3 - see below) the T/RH sensor can be easily exchanged by plugging in/off, be it to exchange a defective sensor, be it to upgrade the factory state SHT31/SHT40 sensor by a SHT35 extra precision sensor, or be it to use a sea salt exposure protected instead of a normal one.

In newer WS80 models, which were delivered by Ecowitt from May 2022 on, the power supply has been extended from the heater (as with the WS90) to the entire sensor array, i.e. the station runs on the external power supply when the supercapacitor charged by the solar panel is exhausted. The new model is not recognisable from the outside. You would have to dismantle it to know whether the model you have bought is already a newer one. (see below)
WS80 hardware revision by T/RH sensor plug: type2 - red ring/black type3 - blue

One phenomenon in this context is that when the power supply unit (new hardware) is connected, the battery voltage is displayed lower than it actually is. When the mains supply is disconnected, the original (actual) voltage/capacity is displayed again. The background to this is that in order to prevent battery voltage being used/consumed during mains operation, the system is fooled into believing that the battery voltage is lower.

Original Ecowitt explanation: “Yes, this is normal as your heater power supplies to the power for the device of ws80 also. The heater power cuts off the battery voltage, and this lead to a lower battery voltage as the battery power supply is being cut off now for battery power consumption saving reason.”
This applies analogously to a WS90 sensor array.

The newer versions of the WS80 (WS85/WS90 analogously) come with an aluminium mesh on the bottom of the wind reading section - it's a surface tension conditioner layer - a patented cover that prevents the formation of water drops that interfere with wind measurements.

The models currently sold by resellers (Froggit, GARNI, WeatherSpares …) are sometimes still older hardware versions (type 1) and only have a power supply for the heater. Since the end of 2022, this has changed and the new hardware (type 3) is now being delivered, which can also be operated completely via a power supply unit - not just the heater.
However, Froggit currently (October 2023) offers WS80/DP1000 spare parts without mounting accessories, all of which are older models. So be careful if you think you can replace an older model with a newer one! The newer model can be recognised indirectly by the fact that the accessible outdoor temperature/humidity sensor located in the radiation shield can be replaced by simply pulling it out/inserting it (as in the WS90) and has a bluish plug end (type 3). Old is either black at the plug end (type 2) or has only one cable leading inwards (type 1). The protection can be removed with two Phillips screws. (Type 2 WS80 sensor arrays produced after April 2022 can also be operated completely with an external power supply - however, they cannot be distinguished from those produced before April 2022 by a layperson. - One would have to open the main housing and check the mainboard (PCB) for the date printed on it.)

The heater is thermostate triggered and switches on at 0° C/32° F provided the external power supply is connected. It doesn't run constantly but only in intervals their length depending on how much the temperature has dropped below 0° C. When the temperature rises again above +3° C, the heater switches off.
Meant to allow for the ultrasonic wind measurement at low and very low temperatures, it has an impact on the outdoor temperature readings - a deviation up to 4° C/4° K has been observed.

On the other hand, the heat produced is not enough to melt snow or ice which have accumuluted on the sensor array top. Snow has to be removed manually, e.g. with a brush or broom. Otherwise the solar readings are obstructed and the supercapacitor is kept from being charged by the solar panel. Under such condition the sensor array will have to run on its backup batteries.

All the heater related information also applies to the WS90 array.


for firmware upgrades of the WS80 see WS80/WS90 firmware

since June 2024 there is also a battery pack for the WS80/WS90 sensor arrays available with a 10 m cable
this can become interesting for users who don't use the external power supply but run into battery issues due to not sufficient solar exposure - or who cant use it for running the whole array because it's still a type1 or early type2 model (see above).

maintenance

The provided solar panel charges a super-capacitor on the WS80. In normal conditions (solar light intensity over 20klux and lasted longer than 4 hours), the super-capacitor peak voltage should be above 3.5v and lower than 5.5v. Please check regularly - every six months recommended - the top part of your WS80 and make sure it is free from dust coverage. Use a brush to clean up the surface for higher solar charging efficiency.

in fact, the sensor name is WS85 - Essence3 is the WS3802 station consisting of a WS3800 console, the WS85 Rain & Wind sensor and a WH32 outdoor T/RH sensor

the WS85 is supposed to be a 3-in-1 outdoor sensor - for wind and rain only
it has a solar panel
it will not have a solar sensor
the rain gauge is that of the WS90
no heating or external power supply available

The WS85 is basically a low-cost version of the WS90.

it definitely needs a WH32(-EP) outdoor T/RH sensor as the array portion of the WS90 housing used for the WS85 for T/RH has been sacrificed for allowing the side mounting

so the housing design is new (“WS90 minus T/RH”) and the PCP has got a new chipset (which one to be found out once a sample is available)

The WS85 is supposed to be OTA firmware upgrade enabled.
Latest information shows that at least at the sales start, the WS85 won't come with the OTA upgrade capability yet. A later implementation is being discussed.

As one can see from the pictures, there are two mounting options available - side-mounting or stand-mounting
The base bracket allows for plugging in for both options.

in the WebUI the WS85 is already visible on the SensorsID page (FW WS3800/WS3900/GW1200 1.3.0, GW2000 3.1.3, HP25x0 1.9.6 …)
once a WS85 is available, WS View Plus (V. >= 1.0.49) will recognize it and display it on the sensorsID page of the supporting consoles with local Ecowitt API.

when you have more than one console/gateway which support the WS85, make sure you go through the registered sensor IDs for all of them and disable the WS85 where you want to have the readings from another anemomter or piezo rain readings from another WS90. The cosnoles will pick up the WS85 signal otherwise and replace the other wind/piezo rain readings by the WS85 readings ! (–> sensor hierarchy)





the WS90 rain gauge accuracy suffered from occasional water accumulation on the sensor top leading to underreading the rainfall amount. With the WS85 the steepness of the slope from center to periphery was increased to allow the water to flow off in spite of its surface tension.


this station will be the WS3802 or “Essence3”

the idea behind the name Essence3 seems to be that the WS3802 station consists of the three primary (“essential”) weather observation sensors: Wind, Rainfall, Outdoor Temperature and Humidity.
Of course, the WS85 can also be combined with a WS3900 console instead of a WS3800 - these are the WS3902 and WS3912 stations.
(for the stations the last number used follows usually the following scheme depending on which sensors/array are included: 1=WS69, 2=WS68, 3=WS80, 4=WS90, 5=WH31 - the WS85 seems to break this rule)

a peep under the hud



for more information about the WS85 see Reviews


for an explanation of the haptic/piezo-electric rainfall detection, WS90 rainfall detection

the WS80/WS90 battery pack also works for a WS85. Mounting at the sensor end like a WS90.

It appears that the WS85 has inbuilt only one supercapacitor whereas the WS90 has two (whether they have the same capacity has still to be figured out). As a result the discharge of the WS85 supercap is visibly faster/more than that of the WS90. Ecowitt promise that the WS85 can run on supercap only for around 10 hours (provided no rainfall is taking please whose detection uses additional power)

Generally available since the beginning of April 2022, this 7-in-1 outdoor sensor measures temperature, humidity, light, UV, wind speed and direction (both ultrasonic) and rainfall (haptic/piezo). Like the WS80 6-in-1 outdoor sensor group, it has a thermostat-controlled heater with an external power supply unit to ensure that the ultrasonic anemometer can also function below 0°C. This is the latest/newest outdoor sensor group from Fine Offset / Ecowitt. Data is sent every 8.8 seconds.

In addition, the power supply can power not only the heater for the rain gauge but the entire station when the supercapacitor, which is charged by the solar panel, is exhausted. Without a power supply unit (12V/1A), the batteries are used when the capacitor is empty. As the WS90 can turn into sort of a battery vampire when it is run without an external power supply, the batteries e.g. in winter due to insufficient solar exposition will not hold longer than two months.

The WS90 is now available individually or together with an HP2551/HP2560 console or the WN1980 console as a package/station (e.g. HP2654 station = HP2560 console + WS90). The upper sensor section is surrounded by an elastic, tight-fitting silicone cover/sleeve, which additionally protects the USB port (firmware upgrade) from water ingress.

The CAL button on the underside of the anemometer section (top - solar and rain, centre - wind, bottom - temperature/humidity) is used to reset the anemometer to a zero baseline if required. If the anemometer displays values even when there is no wind, the WS90 must be placed in a wind-free environment (indoors, cardboard box) and then the CAL button pressed for a few seconds. Next to it is the button labelled RESET for re-initialising the entire sensor group (but without wind calibration). The north arrow (important for determining the wind direction despite the round design) is located above the battery port. The screw of the battery port should be orientated to the north. Ecowitt has developed a specially protected version for the T/RH sensor of the WS80/WS90/WS69/WH65 sensor arrays to protect it from exposure to salty air (e.g. near lakes or in the vicinity of salt deserts, North/South America). Applies only to the new hardware version with plug-and-play sensor. (See picture of WS80) (Attention: due to the design, this sensor is available in two different versions for the WS90 and the other sensor arrays)

At the bottom of the wind reading section there is an aluminium mesh - it's a surface tension conditioner layer - a patented cover that prevents the formation of water drops that interfere with wind measurements.

Regarding a DIY power supply and deviating battery voltage display when connecting an external power supply unit: see the instructions for the WS80 - connections and power supply for the WS80 and WS90 are identical.

A Sensirion SHT40* is used as the sensor for temperature/humidity measurement. However, it can be replaced or upgraded with an SHT35 using an optional upgrade kit with the chip that is also used in the WH31-EP/WH32-EP (EP=extra precision) sensors.
In addition to the battery, the delivery model also displays the charge status of the supercapacitor supplied by the solar panel, which is the main power supply for the sensor group. This is displayed on the ecowitt.net dashboard both verbally and as a numerical value; e.g. LOW / 0.00 V

*) most of the T/RH sensors used also in other Ecowitt sensors are SHT31 based. But don't let yourself get fooled by the numbers. A SHT40 is not really better than a SHT31. It's a different production line of the manufacturer Sensirion https://www.sensirion.ch
the SHT3x line is for industrial use, the SHT4x line is meant for consumer use.


When the heater element in the WS90 switched on to avoid the formation of frost which would impact the ultrasonic readings, as a side-effect, the temperature/humidity sensor housed under the heating plate would be impacted and deviations up +/- 2° C/ 4° F were observed. As a solution a special SHT30 T/RH sensor was built which can compensate these effects.

SHT30 Temp & Hygr with protection filter and compensation function for WS90 only –>

it's an easily user-replaceable sensor (“plug-and-play”)




Also, even though the official picture/design scheme of the WS90 says that the CAL button and the USB port are “for factory use only”, a firmware update of the WS90 can only be done via the USB port.

And a zero baseline for wind readings can only be established by using the CAL button.

Since firmware 1.3.8 the CAL button can also be used to switch off the blue LED which blinks at each transmission interval. Some customers found that irritating and Ecowitt followed their wish for being able to switch the LED off. In order to do so the CAL button needs to be pressed three times with a little gap in between.


ATTENTION: the start-up hardware version of the Ambient WS-4000-ARRAY does NOT have an inbuilt heater (nor can it be run on an external power supply) - therefore wind readings at temperatures below 0° C / 32° F may not be reliable or fail completely

the anemometer heater element of the WS90


the hardware is most likely the same for the WS80 outdoor array.

the haptic or piezo rain sensor of the WS90

the inner life of the top portion of the WS90 - the PCB (printed circuit board) contains the sensor system for rain detection, the light sensor for solar readings and the solar panel and the connected supercapacitor.

the sensor hardware has changed between the ß-test phase (hardware revision 1.0) and the later public release (hardware revision 2.0). One can see that the half-moon shaped rain/piezo sensor from HW Rev.1 has been doubled in HW Rev. 2. These sensors are there to make sure that a haptic impact on the surface is caused by water and not by something else - an issue the Tempest Weather stations which have also a haptic rain detection system haven't been able to solve until today (February 2024). The Tempest stations are hypersensitive towards vibrations, and vibrations created and transmitted via the mast/pole or sound waves from airplanes are creating false positives. Ecowitt has taken here a different approach which can distinguish between a hit caused by vibrations or by water drops.

How to calibrate rainfall with a WS90

you cannot calibrate the sensor, you have to calibrate how the console processes the data received from the sensor - therefore the calibration is with the console/gateway

use either the WS View Plus app or the WebUI (inbuilt webpage) or with the HP25x0 console inside the console

The WS90 is set up in a way that five different linear gain factors can be applied for different rain rate tiers.
The accuracy of the haptic/piezo rain sensor is widely discussed and has meanwhile improved from “poor” to “acceptable”. Still, Ecowitt recommend now on their product web page, to use an additional traditional WH40 rain gauge when high accuracy is wanted.

The reasons for the lack of high accuracy are manifold.

A haptic rain sensor has to fulfill certain criteria. It has to record vibrations originating from raindrops. At the same time it has to exclude false positives created by external vibrations from other sources. This the WS90 can manage quite well. A little issue still remains and needs to be resolved: when it rains lightly quite some water remains on the surface due to the water surface tension. When the water doesn't flow off due to wind or stronger rainfall, it affects the continuous reading i.e. it doesn't register additional light rainfall. This still needs to be solved.

Meanwhile Ecowitt have improved the top portion for the WS85 ("added slope").
As per recent Ecowitt statements (June 2024) the recently manufactured WS90 arrays also already have the modified top.

The characteristic line of the rain sensor, especially in the low rain rate area turned out to be best represented by a square or cubic function of the type y = a * x² or y = a * x³.
That's what many field experiments by users showed. Only then the linear gain factors provided for the different rainrate tiers make sense.

With firmware 1.3.8 most of the observed issues seem to have been significantly reduced. Still, depending on rain type and accompanying winds, there can be deviations of 2-3 mm.

suggested baseline tier gain factors for the WS90

these factors don't claim to be the ultima ratio, but they can serve as an orientation to experiment with yourself

Ecowitt give the following background information to explain the need for different calibration for different rain rate ranges (tiers):
“Piezoelectric rain gauge working principle: raindrops fall on the sensor's surface so that the monitoring panel produces small mechanical vibration, the vibration of the mechanical stress, and the sensor produces a voltage difference corresponding to the amount of rainfall. *1)

In practice, the measurement of precipitation by piezoelectric rain gauges is influenced by environmental factors such as wind, terrain, and debris. In the case of large rainfall intensity, rainfall intensity can be measured by the piezoelectric rain gauge, but the raindrops landing may have two impacts on the monitoring panel*2) so that the measured rainfall value is larger; for minimal rainfall intensity, due to the vertical momentum is being too small, so that the measured rainfall value is also too small. Therefore, it is necessary to calibrate the piezoelectric sensors for different rainfall intensities depending on the environment in which they are located.”

(strike-through, footnotes and addenda/reformulation by WiKi author for better understanding)

*1) as this vibration could have also been caused by other factors, the panel has also a detector which verifies the presence of water to exclude other sources of vibrations
*2) this means that a large drop can “break” into two pieces and show as two drops even though it was originally only one and therefore being double counted

viewing rainfall from a traditional and a piezo rain gauge synoptically
prerequisites:
1. using a console/gateway with the local Ecowitt API
2. having a WH40 or a WS69 and a WS85 or WS90 connected/registered to such a console/gateway


This synoptical view in the WebUI for an Ambient WS-4000-ARRAY is only possible with a WS-1965 or Ambient Weather Hub IP2 or IP3, provided the WS-4000-ARRAY (WS90) is registered to these consoles/gateways.

How to determine the WS90 (and WS85) firmware version

there are three ways how to determine the firmware version of your WS90 depending on the console you have

1. all consoles: hover the mouse pointer over the “Reported xx seconds ago” under the name of your console WiFi firmware name in the top center of your ecowitt.net dashboard
2. with a console with local Ecowitt Gateway API: on the sensors ID page of WS View Plus at the very right of the WS90 or WS85 sensor line
3. with a console with local Ecowitt Gateway API: on the sensors ID page of the WebUI hovering your mouse pointer over the WS90 or WS85 icon

the cable for the external power supply (running the array, heater) usually hanging outside (your cable can be black or white) can be moved inside the mounting piece and be run inside the pole/mast/pipe (provided it is hollow)


for firmware upgrades of the WS90 see firmware WS80/WS90

since June 2024 there is also a battery pack for the WS80/WS85/WS90 sensor arrays available with a 10 m cable
this can become interesting for users who don't use the external power supply but run into battery issues due to not sufficient solar exposure.



(battery pack and installation are the same for a WS85)


maintenance
Ecowitt state:
The provided solar panel charges a super-capacitor on this WS90. In normal conditions (solar light intensity over 20klux and lasted longer than 4 hours), the super-capacitor peak voltage displayed on the battery tile from your dashboard should be above 3.5v and lower than 5.5v. If it is not overpassing 2.5v, please check the top part of your WS90, and make sure it is free from dust coverage. Use a brush to clean up the surface for higher solar charging efficiency.

future development
Ecowitt are working on improving the accuracy of the WS90 rain readings, especially in the low rain rate area. A promising approach seems to be to add an optical rain sensor to the existing design to compensate for the shortcomings of the piezo-alone approach for rain amount detection.

as per a recent statement of Ecowitt (02-Jun-2024) the increased top slope between center and periphery introduced with the new WS85 Rain & Wind sensor is now also inplemented in the newly manufactued WS90 arrays.
it appears that not only a stronger curvature/arch was implemented but also the center piece was slightly tilted to prevent residual water. So that's not a construction defect but a feature !






rain start detection
the WS90 and WS85 now have a rain start detection (detection of first raindrops) implemented. The GW2000 is the first console where this feature is implemented with firmware 3.1.5 - other IoT-enabled consoles to follow.



in the customized server post string, the observation will show as srain_piezo
it can have the status “1” - raining or “0” - no rain
status 1 will be reset to 0
- once the top is dry
- after the amount of water on the top has remained unchanged for two hours

for RTL_433 users: the status bit sits in bit #5 (counted from the right, starting with “1”) in Byte #17 (counting starting with “1”) of the transmission payload.

potential impact of the slope on light (solar) readings

It was suspected by users that it is possible, that with the higher slope end pointing towards South, as the hardware setup (North arrow) may suggest, the slope might have an impact on the light readings during day-start and day-end hours at higher geographical latitudes and low(er) sun position.

During first tests with the higher end of the slope pointing North did not show any impact.
Therefore, for owners of the WS90 with slope before the still to be released elevated light sensor, the positioning of the higher slope end towards North and a correction of wind direction by 180° is recommended.

In addition, Ecowitt will raise the light sensor position inside the array to minimize reading losses due to low solar position even with the high slope end pointing South.

For those wanting to upgrade the top portion (slope, solar sensor positioning) the top part is available as spare part or “accessory”

There is also a WS90 version with a serial RS485 interface (Modbus) - the WN90LP. As the name tells, it has no solar panel and runs on either batteries only or needs to be permanently powered via the 12V/1A power supply which will also run the heater at temperatures < 0° C. It has an extra inbuilt pressure sensor. (N=no solar panel, L=Line, P=Pressure). Firmware updates are done as with a “normal” (RF) WS90 and the firmware is the same.

Its new data provisioning interval (data refresh interval for signal transmission)* is different for different observation types:
rainfall: every 8.7 seconds
wind speed: every 2 seconds
voltage: every 10 minutes
(a WS90 updates all this data every 8.7 seconds)
Querying the sensor more often (one could query via the RS-485 interface every second) will only get “stale” data from the last provisioning.
*) some people don't like the term “transmission” here, even though (signal) transmission is not reserved for over-the-air data transport/delivery but is media independent (can be via cable, optic fibre, air, space …)

It comes with a 2 m 4-wire cable (5-15 V).

V_heater (red) — 12 V power supply
GND_heater (black) — GND power supply
Data_A (green) — RS-485 adapter A
Data_B (white/yellow) — RS-485 adapter B

There is also a 10 m cable available for power supply/data communication. 5 - 15 V.

the legacy TH&P sensor of older Fine Offset weather stations (like a WH1080) is the WH25.

the modern WiFi consoles cannot distinguish between the signal of an old WH25 TH&P sensor and the new WH32B/WH32 indoor/WN32P sensor.

Internally the firmware still identifies them as WH25, be it a real WH25 or a WH32B.


———————————————————————————————————————————————————————————-

the WH26 is the Fine Offset legacy T&H (temperature/humidity outdoor) sensor, the predecessor of the WH32 outdoor.

———————————————————————————————————————————————————————————-

A temperature sensor for liquids with a remote, waterproof sensor that shares the channels with the WH31/WH31-EP (see there). The cable for the sensor is approx. 3m long - therefore apparently no I2C sensor is used but a thermistor.
The WN30 is now (30.04.2021) finally also available from Ecowitt. The WN30 corresponds to the DP30 at Froggit . Internally, Ecowitt also lists the WN30 as WN37xN, i.e. WN37AN for the 868 MHz model.

According to our own tests, the maximum measured temperature is exactly 60°C - the display/output is 60°C even at higher temperatures. Ecowitt has confirmed this and argued that there is no accuracy above this value.

———————————————————————————————————————————————————————————-

An extra temperature/humidity sensor for indoor, outdoor or other areas. This can of course also be installed outside in a suitable housing. However, the measured values of these sensors are reported to the software and the weather services as indoor sensors, more precisely as extra temperature/humidity sensors. An SHT30 is used as the sensor.

The specified temperature range of -10°C to +60°C refers to the built-in LC display - it is therefore only ensured that the data is also shown on the sensor display within this range. As the sensor should be housed outdoors in a weather protection anyway, there is no need for a display. The actual measured values are also transmitted outside the specified temperature range.

The transmission interval is 61 seconds. This sensor can transmit on eight different channels, which are set via small DIP switches under the battery cover. Eight extra temperature/humidity sensors are possible to be registered per supporting console. The WN30 (see above) belongs to the WH31 family and counts towards the channel allocation. The same applies to the WN36 pool sensor (see below) - this one also shares the 8 WH31 channels. The externally recognisable difference to a WH32 sensor (see below) is the presence of the DIP switches and the display of the channel number on the display.

There is a special version of the WH31 with DCF77 receiver, which is offered by dnt as DNT000005 Thermo/Hygro Sensor RF 868MHz. The DCF77 receiver inside supplies the RoomLogg PRO or the WH2800 with the correct time. When used as an additional sensor for GW1000, GW1100, HP2551C, HP3500 - where the station receives the time via NTP - the DCF data is not analysed. Otherwise, these sensors correspond to the “normal” WH31 - i.e. they are processed by the stations like sensors without a DCF77 receiver.

While the dnt sensors with DCF77 can transmit on up to eight channels, there is a reduced version for the WH2800/WH2810 console, the WH31F, which can also receive the DCF77 signal, but can only select three channels. These channels correspond to channels 1, 2 and 7 of the eight WH31 channels.

Whether the station (console) can also receive the time from the WH31 via DCF77 - for example if the NTP server is not available - is unlikely, but still needs to be checked.

A WH31 can be converted to a WH32

Ambient sell a “special” WH31 type of sensor under the name WH51RF as specially designed for refrigerators and freezers.

“The sensor offers flexible placement options such as hanging from a metal wire shelf, mounting on a wall, or simply resting on a horizontal surface. This versatility ensures optimal positioning for accurate readings without compromising storage space or convenience.”

Even though claiming special features, nothing which supports this statement (apart from coming with a hook/hanger and a removable little stand) can be found on their website. The IP rating of the housing is the same as with the normal WH31 sensors.

The housing is Ambient designed - the PCB is Fine Offset manufactured.

The website wrongly claimes that it has a reporting interval of 80 seconds, different from the usual 61 seconds of other WH31 variants.

Please do not confuse it with the WH32 - despite the almost identical name! The WH32B (the B stands for barometer) is the remote sensor for temperature, humidity and air pressure for the HP2551C, HP3500 and WH2650/Froggit WH2600Pro WIFI console. At first glance, the sensor looks like a WH32 - but it is intended for indoor use and, unlike the WH32, can also measure air pressure. It is also labelled “Pressure Sensor”. Ecowitt has also recently started using the designation WN32P (P for “Pressure”). The previous designation - from which the name of the battery value in the Ecowitt protocol also originates - is WH25. The new (February 2024) WS3800/3900/3910 consoles also have built-in T&HP sensors, but can also use a separate WH32B/WN32P as an alternative. There can only be ONE T&HP sensor per console which shows as Indoor (even though you can rename it in different consoles, but the display position remains).

Ecowitt now markets the WH32B as the WH32 indoor and the WH32 as the WH32 outdoor, possibly to avoid the confusion that has repeatedly arisen among users. Froggit also sells the sensor with the HP1000SE Pro console, but does not sell the sensor as a separate item. However, it is probably possible to order a replacement on request.

Note: Ecowitt meanwhile allows to optionally switch off the use of the built-in indoor temperature, humidity and air pressure sensors of the HP2560, WN19x0, GW1100 and GW2000 as a firmware option and to be able to use a WH32B/WH32 indoor instead.

Since firmware 2.3.1/3.1.1/1.2.8, the GW1100/GW2000/GW1200 can also use a separate T&HP sensor (WH32B, WN32P) instead of the built-in T&HP sensors.

A WH32B can be converted into a WH31 or WH32

Temperature/humidity meter for outdoor use. However, this sensor cannot (or can hardly, depending on the location) be used outdoors without a protective housing - it lacks any protection mechanisms against moisture ingress. There can be exactly ONE WH32/WH32-EP in each weather station installation (per console*) (there is only one outdoor sensor defined as such in the Ecowitt world).

Inside the so-called sensor hierarchy it stands on top. This means that the consoles will prefer its readings over all other outdoor T/RH sensors (of a WS69/WH65, WS80, WS90) registered at the same time to the console.
It gives you also the flexibility to more freely choose the location of your outdoor T/RH sensor. The arrays are usually put high up for optiml wind readings.

The values of this sensor for temperature and humidity are preferred by the station; they therefore replace any existing values of a sensor array.

The specified temperature range of -10°C to +60°C refers to the built-in LC display - it is therefore only ensured that the data is also shown on the sensor display in this range. As the sensor should be housed outdoors in a weather protection anyway, there is no need for a display. The actual measured values are also transmitted outside the specified temperature range.

The transmission interval is 64 seconds.

Attention: an unfortunately so-called WH32F is NOT a real WH32 but a special WH31 with DCF77 reception, which was developed for the WH2800/WH2810 console. It is NOT displayed as an outdoor temperature/humidity sensor on any other console, but as an extra temperature/humidity sensor like any member of the WH31 sensor family.

(*GW1200,GW1100/GW1000/GW2000/WH2650/HP2551/HP2560/HP350x, WN19x0, WS3800, WS39x0). The WH2910 (Froggit WH3000SE) and the WH2320E (Froggit WH4000SE) cannot receive a WH32 - they only receive the signals from the WH65/WS69 outdoor sensor group.

the WH32 outdoor/WN32 housing is not waterproof. You need to place it into a protected space or use a shield for protection against the elements - and solar irradiation.

If the sensor is exposed to solar irradiation, you need to use a GOOD (!) and not only good looking radiation shield (or a Stevenson shelter) which is well aired. For passive (= naturally ventilated or aspirated) radiation shields, see Passive Radiation Shields
Some good and better shields only use probes - then the WH32-EP (extra precision) sensor (see below) would be needed.

An improved version of the WH31 with a more precise sensor. The sensor used here is the Sensirion SHT35, which is more accurate, especially with regard to humidity.

The actual sensor is separated from the sensor housing by a cable (~1m). (See picture of WH32-EP below) Like the WN30, the WH31-EP belongs to the WH31 family and counts towards the channel allocation (maximum 8 per console).

The WH31-EP is often referred to internally by Ecowitt as WN37xS, i.e. WN37AS for the 868 MHz model. This is also printed on the housing. WH37AS may have been relabelled WN31-AS in the meantime. The remote sensor on the 94cm long cable has a diameter of 18mm and a length of 68.35mm. The cable has an outer diameter of 5mm.

The improved version of the WH32 with the more precise Sensirion SHT35 for outdoor use. There can be exactly ONE WH32/WH32-EP in each weather station installation (per console*) (in the Ecowitt world there is only one outdoor sensor defined as such). In contrast to the “normal” WH32, the sensor is located in a probe which is led out of the housing on a cable approx. 1 metre long.

The remote sensor on the 94cm long cable has a diameter of 18mm and a length of 68.35mm. The cable has an outer diameter of 5mm.

(*GW1200/GW1100/GW1000/WH2650/HP25x0/HP350x, WN19x0, WS3800, WS39x0)). The WH2910/WS2910 (Froggit WH3000SE) and the WS2320E (Froggit WH4000SE) cannot receive a WH32 - they only receive the signals from the WH65/WS69 outdoor array.

———————————————————————————————————————————————————————————-

This is a temperature sensor for liquids (WN34L) and for soil (WN34S). L = liquid and S = soil

The WN34S is a soil temperature sensor in which the actual sensor (NTC) is located in a metal tube that can be inserted up to 30cm deep into the soil. The tube has a diameter of 10mm. Power is supplied by an AA battery, for which a lithium battery is often recommended, as is usually the case with outdoor sensors. The battery is not included in the delivery package - however, a clamp and other mounting material are included.

The current temperature can be read on the display - in °C for the 868 MHz models. The transmitter unit is identical to the WN34L - so this sensor shares the 8 available channels with the WN34L and the output key (tf_chN) and the transmission interval are identical: 77 seconds. The battery values are transmitted as tf_battN in volts in the Ecowitt protocol (–> customized server). The newer hardware revisions have a little switch inside the battery compartment where the displayed unit - °C or °F - can be selected.

A silicone seal in the battery compartment makes this sensor actually appear waterproof (IP65 is the specification) - however, long-term experience is still lacking. The measuring range is specified as -40 - +60°C - so use in most latitudes(Europe, North-America, Australia) should be assured. After pressing the tube in the ground, the setup is surprisingly stable. The WN34L measures the temperature in liquids, but can probably also be used to measure the temperature in air. The actual sensor (NTC) is attached to an approximately 3m long cable. Clamp and mounting material are included, but not the AA battery required for operation.

Interestingly, the WN34 sensors are not listed in the firmware (and thus in the internal GWyx00 API) as soil temperature sensors, as perhaps expected (the WH51 sensors are listed as soil moisture sensors), but as user-defined temperature sensors. [Details see Ecowitt Gateway API]

This is a leaf moisture sensor for 8 channels.

The WN35 leaf moisture sensor is like an artificial leaf and measures the moisture (in per cent) as a result of precipitation/dew. Up to 8 (!) leaf moisture sensors are possible - each working in its own channel. Power is supplied via an AA battery.

The transmission interval is 79.5 seconds.

It can also serve as an early rainfall detector.

The rain gauge for operation with individual sensors.

One measuring spoon emptying corresponds to a rainfall of 0.1 mm/m² (or litres/m²). (In comparison, one measuring spoon emptying corresponds to 0.254 mm/m² for the rain gauge of the WH65 sensor group). The measurement is therefore taken in 0.1 mm increments (WH65: 0.254 mm increments). Strictly speaking (due to rounding errors when converting from inches to the metric system), a tipping of the measuring spoon reported as 0.1 mm corresponds to 0.102 mm - therefore a calibration of 1.022 should be set in the console when using metric units.

The transmission interval is 49 seconds. The original hardware revision cannot send the battery value - so an empty battery is only detected when the sensor is no longer sending data. It only sends a constant fake value of 1.4 Volts.
The devices sold by Ecowitt from summer 2021 are now able to transmit the real battery level. (Details –> table below)
Those devices sold under the Ecowitt label show the hardware revision on the battery door.

Due to the design (very flat and large rain funnel and a very low edge of the funnel), measurement losses due to splashing occur in heavy rain and/or in combination with strong winds (overblow loss).

A 5-6 cm (~ 2 inches) high attachment created with a 3D printer (or the attachment of rigid plastic wrap of the same height) significantly improves the measurement result. (see below)

Inspired by the 3-D model, Ecowitt now offers a 2 1/2 cm high attachment as an accessory, which is mounted using the fastening strap of the bird repellent attachment. If you do not already have the bird repellent, you must order both.






Ecowitt have meanwhile conceptualized a new funnel with a +/- 5 cm rim which also contains holes to insert bird spikes at the top end of the rim.

all new WH40 will be delivered with the new funnel - bird spikes will be included
the new WH40 will also come with an UV resistant housing, the same material as the WS90
prospective sales date: mid- to end-January 2025 - before the start of the New Chinese Year [29-Jan-2025]

the highest processable rain rate of the WH40 is ~ 360 mm/h, one measuring spoon emptying per second the rain rate is determined/averaged over 10 minutes with a resolution of one minute (with the rain gauge of the WH65/WS69 it would be 900 mm/h (0.254 mm per measuring spoon emptying))

By the way, there are always questions about the definition of a
rain event.
The Ecowitt definition is: “Rain event is defined as continuous rain, and resets to zero if accumulated rainfall is less than 1 mm (0.039 in) in a 24 hour period.”

Continuous rain ends when there is no further rainfall registered within one hour. A rain event therefore ends if no rain has fallen for one hour since the start of rain and accumulated rainfall >= 1 mm and it has not rained more than 1 mm within the following 24 hours

attention - the definition used by AWN for rain event is different from the above definition, but what is shown on the console display goes by the above definition

attention : it has been repeatedly reported that the WH40 signal becomes unreceivable when the battery compartment points towards the receiving console/gateway. Please make sure the battery compartment points away from the WH40 - console line.

some details on the rain information transmission
the rainfall information transmission contains a 2-byte counter which starts at 00 and ends at HEX FFFF (65,535) where it will be reset to 00 (after having counted 6,553 mm or 6.55 m³ rainfall).
The console saves the counter information in the RAM and determines the rainfall by the difference of the last saved counter and the actually received counter. Like this missed transmissions will be caught up with.
During a console reset/reboot/power cycle the counter information gets lost ⇒ each reset can potentially produce an error of 0.1 mm rainfall (= losing 0.1 mm) - which can be compensated by manually adding 0.1 mm to the daily/weel/monthly/yearly rain totals after a reboot.

Air quality sensor for outdoor use. It has 2 AA NIMH rechargeable batteries that are charged* by the integrated solar panel. In the winter months in northern European latitudes, it must be assumed that the WH41 must be charged manually (via a USB cable) every fortnight. The sun is then not sufficient to charge the batteries.

(*) one should better say: whose charge is maintained for a longer period - even in summer time in Northern European Medium latitudes (45° - 55° North) the solar panel cannot fully maintain the charge and a manual recharge becomes necessary after 6-8 weeks - either via the micro-USB charging port between battery compartment and housing wall or via already externally charged batteries)

Although the model is labelled for outdoor use, it can of course also be operated indoors as long as the console can receive the signal from the sensor.
The sensor used originally is a Honeywell HPMA115S0-TIR has been meanwhile replaced by a CPM2005 from Senseiot or most recent a Plantower model.

The transmission interval is 10 minutes - when power connected via the USB port the interval is 60 seconds.

Ambient Weather has produced a very helpful document on cleaning. The text is only available in US-American. However, with the Google Translator or better the German https://www.deepl.com translation service, a comprehensible translation should be possible. Otherwise, the pictures alone may also help.
see PM2.5 maintenance

There is also an alternative cleaning instruction from a weather station owner from the Netherlands in wxforum.net with lots of pictures (also in English): https://www.wxforum.net/index.php?topic=44019.msg448034#msg448034


The sensor is sensitive to high humidity when/where minute droplets will be detected as false positives.

Newer models of the WH41 have the USB charging connector also outside like the WH43/45/46 - the connector is micro USB. The newest models should have a USB type C socket (EU regulations)


The WH43 is the indoor version without solar panel and there the micro-USB port is accessible from outside. (This port will in future also be USB type C only)

1. RF indicator
2. USB charging port (micro USB/USB type C)





more WH41 information:

Ecowitt write on their website: “The sensor is sensitive to liquid droplets - rain/fog/sprinkling. When the Dew Point is close to the outdoor temperature(T - D < = 2°C), the PM2.5 reading will be very high (which is not the real condition). If (you) mind, please don't purchase.”

A DIY setup (plexiglass) to protect against direct rainfall still providing enough airflow has been proposed - see example Another “hack” sometimes used is to permantently connect a USB cable with a 90° angled micro-USB plug, drill a hole into the black housing portion and the covering lid (put some silicone seal around the outer hole) and keep the WH41 permanently charged, be it with a powerbank, a solar panel or a power-grid connected charger.

One more “hack”, which became necessary at very low temperatures (below -18° C) in Canada where the batteries froze, is to replace the batteries by a supercapacitor. see using Supercapcitors to winterize WH41 and improve cold temperature performance

Improved 5-in-1 air quality sensor for indoor use. Looks very similar to a WH43 on the outside (same housing, same miniUSB charging port), but combines 5 sensors. In addition to PM2.5, it also measures PM10, temperature*, humidity* and CO₂ levels. Although 2 AA batteries can be inserted, we recommend using a USB power supply unit. In battery operation, the batteries run out very quickly - despite the significantly reduced transmission frequency.
WH45 manual

The transmission interval is 60 seconds with an external power supply. If the WH45 is operated with batteries, a measurement and transmission to the weather station console only takes place every 10 minutes.

*) the temperature and humidity readings are NOT shown as indoor temperature and humidity; this is reserved to only one sensor.
For more details about temperature sensors in the Ecowitt ecosystem see different types of temperature sensors

The WN46/WH46 (release date March 2024) is the successor of the WH45. It's now a 7-in-1 air quality sensor and provides in addition to the WH45 also PM1 and PM 4 readings.
WH46 manual
All these readings are visible in the Ecowitt dashboard, the Ecowitt app and the WebUI with live data.
They can also be seen in the WS View Plus app as it reads the data API via the the local Ecowitt gateway http API and on the HP25x0 console display. The local Ecowitt gateway API (“telnet API”) will no longer be further extended as per Ecowitt, but the WH46 PM1/PM4 data are still contained, even though not officially documented.

A portion of the readings (CO₂, PM1. PM2.5, PM10) can also be viewed in the date tile of the WS3800/WS39x0 consoles.


Recently (August 2024) a WH46D, D for Display, has been announced. The WH46 7-in-1 sensor array with an integrated LCD display with touchbuttons which like this can also be operated independent of a console/gateway. The registration with a console of the same radio freqeuncy is of couse also possible and when posting to ecowitt.net it will be recognized as an AQIN (air quality indoors) sensor like a WH45/46.
the WH46D manual is available here.
the WH46 will no longer be produced and will be completely replaced by the WH46D
the WH46D is out for sale since 14-January 2025

The only console on which all the WH45/46(D) sensor values can be seen/shown are the HP25x0 console (for WH46(D) with device firmware >= 1.9.5). The values are displayed in a cycle mode in the 3rd line under the outdoor temperature and wind readings (left page half). The T/RH readings can be seen in static or cycling mode on the right page half in the area where also the indoor and WH31-family extra temperature sensors are displayed.

The WS3800/WS39x0 console do not display the PM4 and T/RH readings of the WH46(D).

Beyond HP25x0 and WS3800/WS39x0, the WH46(D) readings can be seen together only in the WS View Plus app (for consoles/gateways with the local Ecowitt API), the ecowitt.net dashboard or in the Ecowitt app, the latter being a copy of the ecowitt.net dashboard for smartphone and tablet viewing. The same applies to the T/RH readings of a WH45.

The WH48 is an eight channel Ambient only CO₂/T/RH (3-in-1) sensor and not yet published by Ambient so far (November 2024). It will come in a new housing and an integrated display. The Ambient consoles (WS-2000/4000/5000; AWN Weather Hub [IP3] and ObserverIP2 [IP2]) will be able to register up to eigth of the new WH48 sensors. Ecowitt consoles won't be able to process the WH48 transmissions. With AMBWeatherPro firmware >= 5.1.7 they can be posted to AWN.

Similar to the Ecowitt WH46D (7-in-1 air quality sensor with display) it can be used stand-alone without being connected to a console/gateway.

The soil moisture sensor reports the moisture in the soil with a value from 0 (dry) to 100 (liquid).

The transmission interval is 70 seconds. However, this transmission interval is adaptive - in the event of a major change within a short period of time, the transmission interval is reduced to 10 seconds and set back to the standard interval once the value has levelled off.

The exact procedure is as follows:
There is a so-called transmission boost, which occurs when the humidity suddenly changes (usually upwards). The system then switches to a 10-second transmission interval, with seven (7) transmissions every 10 seconds. An internal counter (transmission boost) then counts down from “7”. When “0” is reached, transmission resumes every 70 seconds. Until the next major change. It has been observed that a WH51 still reported a value of 1.3V and 1.4V after almost 2 years - so they were still good for use. As a precaution (the batteries should not leak), the are better replaced they being considered empty (⇐1.2V).

After some time Ecowitt started delivering the WH51 together with a plastic cap of the same green colour which is supposed to protect the battery compartment from water ingress.

The WH51 provides a so-called AD value which can be “calibrated” or scaled. While in the agriculatural context of soil moisture AD usually stands for “Allowable Depletion” (see https://soilsensor.com/soil/soil-moisture-and-irrigation/ ), the Ecowitt uses a more simplistic definition and refers to a “Analog to Digital” Soil Moisture Calibration or scaling:

The soil moisture sensor provides for optional two-point linear calibration. This is important due to different soil types and density. The calibration equation is defined as: % Soil Moisture (calibrated) = (Now AD – 0%AD) *100 / (100%AD – 0%AD) Where AD stands for “analog to digital” and is the unscaled digital value, Now AD is the currently measured AD and the other parameters are described below.

0% Soil Moisture Set Point To determine the 0% soil moisture, collect a soil sample in a cup from where the sensor will be installed, and allow the soil to completely dry out. Next, place the soil sensor in the medium and allow the sensor to stabilize for one hour. Next, set the 0%AD calibration set point to the Now AD value.

100% Soil Moisture Set Point To determine the 100% soil moisture, collect a soil sample in a cup from where the sensor will be installed, and add water and mix until the soil is saturated, and there is no standing water. Next, place the soil sensor in the medium and allow the sensor to stabilize for one hour. Next, set the 100%AD calibration set point to the Now AD value.

Customize and Reset Once the 0%AD and 100%AD are entered, set Customize to ON. To return to the non-calibrated settings, set Customize to OFF. Select Reset to restore to factory default

Starting with GW2000 firmware 3.1.5 and WS6210 firmware 1.0.4 all IoT capable consoles/gateways will be able to support 16 instead of before 8 WH51 soil mositure sensors.
all WH51 sensors channel 1-16 will can be used for smart IoT plans (latest firmware upgrade assumed)

The WH51L is a soil moisture sensor for more difficult environments. While the normal WH51 is generally well suited for potted plants etc., it showed reception problems with the respective console at low-lying measuring points. With the WH51L, the transmitter sits in a remote housing, which also has a display window, and has a one metre long cable, so that better and more distant reception (100 m free field) is possible by mounting it higher above the ground. It shares the eight WH51 channels with the “normal” WH51, analogue to the WH31 family or WN34 family.

In addition, the measuring probe can of course now also be inserted deeper into the ground, which opens up a wider range of applications depending on the plant, root depth, etc. The WH51 (without L) could be inserted just 10-15 cm deep.

The sensor has also been available to order in the Ecowitt shop since 14 November 2023 (https://shop.ecowitt.com/products/wh51l ).

laser-based water level and snowfall height detection sensor

(prospective release date: March 2025)

For the WH54 (a.k.a Laser Distance Sensor LDS01) four channels are available per one console.
The display and transmission housing is of the WN34 type, and between housing and sensor (the level meter) a 1.5 meter long cable is attached. (similar to the WH51L - see metrics picture below)

The sensor utilizes laser measuring technology, providing up to
- 4 meters of measurement range when not exposed to natural light and
- 3.5 meters range when exposed to natural light

the sensor shows three values:
air (distance between sensor and surface [water, snow]),
thi (total height, user defined distance between sensor and ground) and
depth (depth = thi -air)

The sampling rate is once every 20 seconds - data transmission is every 80 seconds
If the measurements between two adjacent readings differ by more than 5%, the data is immediately sent.
The sensor then enters the so-called fast measurement mode where the sampling and the transmission is every 10 seconds.

the units displayed on the sensor display can be chosen by a switch inside the housing under the battery.
units shown in the apps or in the WebUI will depend on the unit settings chosen for your console in the respective app or WebUI. The unit will be the same chosen for rain data.

the specification speak of a measurement field of view angle of 5° (to be updated !).
however that needs to be updated as Ecowitt has introduced an additional lens to focus the laser beam. The angle is now 2° ⇒ at 1 m distance the cone covers a circular area with a radius of 3.5 cm ⇒ arctan (0.035) = 2° ⇒ diameter at 1 m is 7 cm, at 3.5 m (max distance in daylight) = 24.5 cm and at 4 m (dark) = 28 cm
That also means that these are the minimum distances from a wall or any other obstacle (e.g. pipe diameter)

realising the need for a heater and resulting from that for a stronger power supply than the initially conceptualized 1.5 V AA battery, the sensor was redesigned and a battery package holding 8 AA batteries was added. A dummy battery building the connection to the external battery compartment is used in the (WN34/35,WH51L,LDS01) standard display housing.


On a HP25x0 console the display will not be on the main screen but on the Extra-Sensor page (4 x arrow-up/down button). Depth will only be shown once “total height” is configured.

on the HP25x0 and the WebUI calibration page the heater-on counter can be reset/changed.

A water leak detector. Powered by 2 AAA batteries, this sensor reliably reports any puddles that occur - both acoustically via a loud beeper and with corresponding notifications on the console or the (supporting) weather services. With Ecowitt you can be notified by e-mail.

The transmission interval is 60 seconds.

The lightning sensor reports and counts lightning within a radius of approx. 40km and outputs the approximate distance. An AS3935 chip is used internally. The built-in sensor receives signals in the 500 kHz band and analyses them for patterns characteristic of lightning discharges. Of course, this can also lead to “false alarms”, especially if, for example, household appliances also generate such patterns. Starting refrigerators, for example, often generate so-called false-positive events. It is therefore generally advisable to install the device outside, possibly in a protective housing.

Meanwhile Ecowitt offers the WH57 together with their RS0001 radiation shield which is pretty useless for a T/RH sensor exposed to direct sunlight. But as a protection against debris and rain it can be helpful.
When an event identified as a lightning discharge is registered, an orange LED lights up in the viewing window with the lightning symbol.

The transmission interval is 79 seconds.
When the first lightning bolt is registered (and also for subsequent lightning bolts), the 79 second interval is interrupted and restarted so that the message arrives promptly. The timestamp of the last lightning event is set by the console that receives the WH57 signal. The distance and number per measurement interval come from the WH57. The (one) WH57 can only be displayed on the screen on an HP25x0 or HP350x console. The Ecowitt app and the WS View Plus app also display the lightning data (WSV+ also in real time if the local gateway API is available) as does the Ecowitt dashboard - on a one minute basis if that updating option is chosen in the console.

As there are always uncertainties regarding the setting of the DIP switches - here is an extract from the instructions:

The left-hand DIP switch decides whether the antenna is used inside (top) or outside (bottom). The second switch from the left (apparently) switches between two antennas. And the two switches on the right change the sensitivity.

When delivered, all DIP switches should (actually) be down. However, there have already been reports that the DIPs were in a different position on arrival.

More information about how the WH57 works: as3935_datasheet_en_v2.pdf

Many WH57 user deploy the WH57 outside e.g. fixed at a mast inside some protective cover or housing with the default settings - i.e. all DIP switches in the lower position.

Testing/troubleshoot the WH57 function:
create a spark with a traditional lighter or a camera flash close to the sensor - the orange sensor LED should flash and it should register the discharge pattern as a lightning in the console/app (even though this would be a false-positive). If nothing happens, resetting the sensor may help (= take off batteries, wait for a minute, re-insert)

Not a sensor but a webcam that takes a photo at a definable interval and sends it to Ecowitt.net, which then generates a film from the individual photos. The technical specifications are somewhat confusing on Ecowitt.com, as they describe characteristics that a user would not normally recognise. The camera is IP66 protected against water and solid bodies and has a resolution of 2 MegaPixels. The lens angle is 150°. Image files are generated in JPG format and transferred to the Ecowitt Cloud, where a time-lapse film can be created from them. Hosting images in the Ecowitt Cloud is free for 7 days. Pricing models for longer storage are not yet published. Size: 41*41*71.5mm

Details:
You can retrieve current images from the local network via http/GET. Only images are created - no video stream. Formats: 640 x 480 and 1600 x 1200 pixels.
Transmission via FTP is not yet available at the time of delivery (March 2024), but is promised to be added later via an upgrade. The camera connects to the local router via WiFi (2.4 GHz) and is a device in the local network. Images are taken every 5/10/15/20/25 minutes, depending on the setting, and transferred to the Ecowitt cloud.
The camera has a WebUI or can be configured via the WS View Plus app.
The HP10 has been a possible device in the WS View Plus app for some time.
The HP10 manual can now be downloaded from Ecowitt (English): https://osswww.ecowitt.net/uploads/20220909/HP10%20manual.pdf

The official operating range is between 0 °C and +50 °C; users from North America report perfect functioning down to -22 °C.

WiFi provisioning or pairing or connecting your console/gateway to your local WLAN

when you use the LAN (Ethernet) interface of a GW2000 or GW3000, then you just have to plugin the network cable at both ends (console and router). The router should then instantly provide the IP address and the device can be configured with all the tools (apps, WebUI) shown below - the connection via WLAN is a longer process - see below

you can only start the pairing process when the console WLAN access point (AP) is active (exception: GW2000, GW3000, ObserverIP 2.0, Ambient Weather Network Hub 2.0 which also have a LAN interface and where the pairing can be done alternatively using by the help of a LAN cable.). The AP will only be active or can only be activated by pressing a button or a button combination [see console manual], when the console is powered by an external DC power supply. When running on batteries only, the AP will remain switched off (exception WS6006, WS6210).

you can only connect the consoles/gateways to a 2.4 GHz WLAN
(if you also run a 5 GHz WLAN with the same SSID, switch it off until the pairing is successfully completed !)

before you start the pairing process, switch off your mobile network in the smartphone or tablet you are using for the pairing
usually this is done by switching on the flight mode (air plane symbol) and then switch on WiFi only
once the pairing is successfully completed, you can switch off the air plane mode which will activate your mobile network connection again
you will be guided by the WS View Plus app through the whole process
below we will describe this process step-by-step and explain what you have to do and why
in principle you tell your console how it can log in and register with you router

1. start WS View Plus
(you will have to download and install it first on your smartphone from your app store [GooglePlay, AppleStore])
you will see the device list - the number of entries is the number of Ecowitt consoles the app detects in the local network
the entries in the device list will look as shown in the above picture (WS View)
(when this is your first time to connect an Ecowitt console with your router, the device list will be empty)
in the WS View Plus app you can select a device as Favourite - the device will then show in the Favourites list. When making a device list entry to a Favourite, you can assign an icon/picture of the console type and can change the default name. Default is EasyWeather-WIFIxxxx, EasyWeatherPro-WIFIxxxx or device-WIFIxxxx (see example above)
2. press on the (+) button at the bottom center
you will get a list of console pictures
3. select your console type
4. activate the WiFi mode of the console
you will receive instructions how to put the console into WiFi mode (= the console starts an internal WLAN with the name of the device or the WiFi firmware - see above - to which you can connect with your Smartphone or tablet)
5. connect to the WLAN of the console
in the WLAN/WiFi setup of your smarthone the name of the console WLAN network (SSID) will appear in the list of available network. For a HP25x0 console it will be EasyWeather-WIFIxxxx or EasyWeatherPro-WIFIxxxx, where xxxx are the last four characters of the console's MAC address. For a GW1200 it would be GW1200-WIFIxxxx.
You select this wireless network and connect to it. Ignore the message that there is no internet connection available. That's correct, but for what you are going to do you don't need it.
6. provide router login information to the console
Once the connection is successful, you will see a page where you can select the mobile networj of your WLAN router or access point. You can make the smartphone search for this network (SSID) and select it. Then you also have to enter the password of your router. The console stores this and will later establish the connection with the router.
you will choose “Next” from here and the console with try to pair with the router (login with SSID and password and then receive an IP address from the router). Once this is completed, the app will take you back to the network list where you can now choose the network you usually use with your smartphone or tablet.

7. start using your console in your local network and with the weather services you choose
as a result your console will now be able to post data to the internet via your router when you have this posting activated in the console.
if your console has the local Ecowitt gateway API, you can now also see the live data in WS View Plus /or in the WebUI connecting with the IP address of the console. This IP address can either be found in your router or in the device list of WS View Plus.

In rare situations, depending on your network setup, it can happen that your router has run out of its IP address budget of DHCP assigned IP addresses - then the console/gateway won't get an IP address assigned.
you will then have to extend the dynamic IP address budget/range of the router.
Once you have finally received an IP address, set it to “IP Address Mode static” in the WebUI of your device (gateway/console) where possible. With some older device this is not possible (GW1000/WH2650/WS2320/WS2910). The WS View Plus app doesn't offer this option - it's WebUI only
(WebUI is the local webpage of the device showing when you enter the IP address of your console/gateway in the web browser)

if in step 4 you are asked for a network security key,

you (or someone else) has set a password for the WebUI (embedded web page) access earlier and this also becomes the password for the WLAN (“WiFi network”).
For the name (SSID) of the WLAN/access point see step 5 or WiFi firmware.


how to pair your gateway with you local network (LAN) by using a LAN cable ?
(applies to GW2000, GW3000, ObserverIP 2.0, Ambient Weather Network Hub 2.0 gateways)

just connect the gateway via a LAN cable to the local network (router or switch). The router will recognize the device and (if the dynamic assignment of IP addresses [DHCP] is activated, default situation) will pass an IP address to the gateway. The gateway can now be reached in the network by entering http://IP-address-of-gateway into your browser.
how to find out the IP address ?
check the router - usally there is a range of IP addresses, the last one provided in that range, the last number of four triplets e.g. 192.168.1.xxx is likely to be the IP address of the gateway. You will have to very by trial and error.

You can also start the WS View Plus app. It will show Ecowitt devices in the same local network where the console(s) is (are) in with an entry in its device list. Per entry also the MAC address and the IP address are shown.
For a GW2000 the entry in the device list will be:
Device GW2000x-WIFInnnn, MAC nn:nn:nn:nn:nn:nn, IP xxx.xxx.xxx.xxx, VER 3.x.x,
(Ambient Devices will only be shown in WS View Plus up to app version 2.0.48 –> WS View App section)

We recommend to make the gateway IP address static - this you can do in the network configuration of the gateway in its WebUI.
————————————————————————————————————————————————————————————————-

before you upgrade your firmware, make sure you have noted down (pencil, photo, screencopy) your calibration and rain total settings - it has often been observed that these data get unintendedly lost during the upgrade. Better safe than sorry !

A procedure how to backup and restore your calibration setting via a script (a sequence of operating system commands) on a Linux based server (e.g. RaspberryPi, NAS server, Linux container etc.) can be found here: - works with all consoles/gateways which have the local http API

NOTE: during a console/gateway restart/reboot (which also happens after a firmware upgrade) the values for maximum daily wind speed (gust) and of a rain event will get lost an strt counting again

there are two types of firmware for the FineOffset/Ecowitt (clone) consoles:

a) WiFi firmware for the upload to the Weather Networks and a customer server (if the console supports), usually starting with EasyWeatherVa.b.c/EasyWeatherPro Va.b.c (or AMBWeatherVa.b.c for Ambient devices)

The separate WiFi firmware is called EasyWeather V.x.y.z (e.g. EasyWeather V.1.6.4) or EasyWeatherPro V.5.x.y for the consoles with a new WiFi modem.

For Ambient consoles the separate WiFi firmware is called AMBWeather V.x.y.z (e.g. AMBWeather V.4.3.5) or AMBWeatherPro V.z.x.y for the consoles with a new WiFi modem.

The consoles with the EasyWeatherPro or AMBWeatherPro WiFi firmware also have a WebUI, which can be accessed in the local network via https://IP-address-of-the-console. They also can, when activated, build their own WLAN (“Access Point” - SSID = EasyWeatherPro-WIFIxxxx or AMBWeatherPro-xxxxxx or WS1965-WIFIxxxx) and when your computer or Smartphone is connected to that network, the console can be reached via IP address 192.168.1.4).Via this network the initial setup/pairing with the local network router can be done via the WebUI. Otherwise WS View Plus or the awnet app is needed. During normal operation it is recommended to switch it off (option on the device settings page in the WeBUI)

if the other features of the WebUI, as the pictures in the quick setup page of the Ambient manual for the WS-2902D suggest, like viewing live data and configuring device settings beyond a WS-1965 or Oberserver IP 2.0 module is questionable and needs to be verified. It's likely to be an error introduced by a copy-and-paste error. It's likely only to be the network and weather network configuration.

b) console/device firmware, which usually just shows the version like Va.b.c (a, b, c = major version, minor version, patch level) which handles the reception and processing and display of the sensor readings
(The reason for the two firmwares lies in the internal construction. With the classical display consoles the main processor handles all activities including a WiFi modem which the WiFi firmware is for)

the GW1200/GW1100/GW1000/WH2650/GW2000, WN19x0 and WS3800/WS39x0 consoles have a combined WiFi/console firmware
(They have a separate WiFi SoC (system on a chip) with its own processor which handles the WiFi communication. They are faster than the classical display consoles: WS2320, WS2910, HP25x0, HP350x)

The above said also applies to the Ambient WS-1965 console (a Ecowitt WN1920 clone) and the Ambient Weather Hub/ObserverIP 2.0 module (an Ecowitt WH2682 gateway with similar functionalities like a GW2000 except for IoT features).

The WH2910 and WH2320/WS2320 also have two different firmware types, but their device firmware CANNOT be updated - it is set by the manufacturer. However, the WIFI firmware can be updated via the app. Certain eatures of the device firmware of the WS2910 depend on the firmware version (see console description)

there are two to three upgrade procedures depending on the type of firmware (WiFi, device)
WiFi
a. via the WS View Plus app
b. OTA (over the air - here = WiFi) for consoles with the EasyWeatherPro/AMBWeatherPro firmware from inside the console
c. via a WebUI (URL = https://ip-address-of-the-console) for consoles with the new WiFi modem (also EasyWeatherPro WiFi firmware)

the WiFi firmware upgrade page for Ambient consoles with the new WiFi modem and the AMBWeatherPro WiFi firmware looks like this
(Ecowitt (clone) consoles see farther down):




console/device:
the device firmware of the WS2320 and WS2910 consoles cannot be user upgraded
(the below procedure also applies to the Ambient WS-2000, WS-4000, WS-5000 consoles - they share the same firmware)

the device firmware of the HP25x0 and HP350x consoles can be user upgraded

the upgrade is done by the help of a microSD card
(type SDHC only, SDXC doesn't work; format FAT32; max size (defined by SDHC) 32 GB)

it appears that newer HP25x0 consoles (to be recognized by having the EasyWeatherPro WiFi firmware) also have a new SD card reader which can manage SDXC cards. But using large capacity SD cards for storing the sensor values doesn't make much sense - a 16 GB microSD card can hold the maximal possible sensor number data for about 150 years - about 100 backups of 16 MB included.

the file user.bin is downloaded from ecowitt.net (link under “Manuals and Software” at the console page on ecowitt.com or from the WiKi at the “latest firmware” section) as a zip archive and after unpacking/unzipping the file user.bin in copied into the root directory of the microSD card. Then the card is inserted into the console (looking at the display, the contacts of the microSD card should show towards you and the printed surface away from you). Be careful to insert the microSD properly until it snugs in. Once inserted the console applies the firmware upgrade automatically and reboots the console. After the successful upgrade the console deletes the file user.bin from the microSD.

the use of cheap (and therefore often “crappy”) microSD cards can also make the firmware upgrade fail

from device firmware V. 1.9.5 on the device firmware upgrade can be done via the console over-the-air (OTA: here WiFi) for the newer HP25x0 models which have the new WiFi modem and the (recent !) EasyWeatherPro firmware.



below the result of an OTA device firmware upgrade for an Ambient WS-2000/WS-5000 consoles with the new WiFi modem


combined WiFi/device firmware
the upgrade is done via the WS View Plus app (all consoles/gateways with local Gateway API) or the WebUI (WN1980, WS3800, WS39x0, GW1100, GW1200, GW2000). When connecting to the console from WS View Plus by tapping on the entry in the device list, a window with an upgrade-available message appears when a new upgrade has been released. Accepting the upgrade offer will download the new firmware, install it and reboot the device.
in the WebUI an available upgrade is indicated by a red dot at the “Device Settings” option on the left-hand side menu.

below shown is the update via WSView (Plus) app

the WS View (Plus) device list and the upgrade offer after tapping on a device list entry


even though the pictures are from the old (discontinued) WS View app, the procedure is the same in the new WS View Plus app. For this only the background colour has changed from greenish-greyish to white.

the Device List and Favourites List in the new WS View Plus app
(for more details to the WS View Plus app see separate chapter)


the procedure is highly automated.

1. start WS View Plus -
you will see the device list - the number of entries is the number of Ecowitt consoles the app detects in the local network
the entries in the device list will look as shown in the above picture (WS View or WS View Plus)
in the WS View Plus app you can select a device as Favourite - the device will then show in the Favourites list. When making a device list entry to a Favourite, you can assign an icon/picture of the console type and can change the default name. Default is EasyWeather-WIFIxxxx, EasyWeatherPro-WIFIxxxx or device-WIFIxxxx (see example above)
2. select an entry in the device list
there are two scenarios:
1. you own a WS2320, WS2910, HP350x or HP25x0 console (or clone model)
if a WiFi firmware upgrade is available, a pop-up window will appear and offer the upgrade. If you accept, the upgrade will take place and the console will be rebooted. If you reject, the upgrade will only be offered again when you start WS View Plus again from the start. (The app has to be closed and completely removed from the memory - otherwise it will not check for upgrades again).
2. you own a console with the local Ecowitt gateway API which have a combined WiFi/device firmware
if a firmware upgrade is available, a pop-up window will appear and offer the upgrade together with change log information. If you accept, you will be taken to the device settings (caption “System”) and you have to press the “Check new version” button. If a new version is available, a pop-up windows will appear offering the upgrade. If you press “OK”, the upgrade will take place and the console will be rebooted. If you reject, the upgrade will only be offered again when you start WS View Plus again from the start. (The app has to be closed and completely removed from the memory - otherwise it will not check for upgrades again). Alternatively you can go to device settings (Live Data –> More –> Device Settings) and press the “Check new version” button again.

the analogous procedure can be done with the consoles which have an integrated webpage (WebUI). There a red dot will appear next to the “Device Settings” menu item when a new firmware version is available.

you can also choose an automatic upgrade in either the WS View Plus app or the WebUI.
we strongly discourage to use this setting as it is nearly impossible to go back to an earlier firmware version.
Exception: the device firmware of the HP350x and HP25x0 consoles. Here you can use an earlier version of the user.bin firmware file (provided you have kept it).Italic Text
you better wait and check in the weather forums - e.g. https://www.wxforum.net/index.php?board=111.0 what early adopters are reporting.

most of the above said combined in a few-pager can be found here: firmware upgrade procedures
(these procedures ONLY work when you are connected with your update-performing device to the same local network your console is registered to !!! - And to perform an OTA (over-the-air) upgrade, you also need an internet connection to download the firmware from the upgrade-server !)
