Weather Station Hardware > Ambient Weather and Ecowitt and other Fine Offset clones

MUST READ - Fine Offset Clone Models,sensor compatibility,firmware + other info

<< < (2/4) > >>

7. sensor battery status, values etc.:
this is a rather special and deep dive topic the common weather station user is often not very much interested in,
at least not in the details. Enough to see somewhere if a battery needs to be replaced or not (yet).

For those who want to go to the bottom of it, there are a few links below which can provide you with detailed information in this field

8. data flow between sensors, consoles, application software, weather services etc.:
 [ You are not allowed to view attachments ]
popular examples for templates are Weather34 (stand-alone or e.g. inside Meteobridge on Raspi), Meteotemplate,
CumulusMX default web site or pwsDashboard (which could also be a direct feed from a console or e.g. FOSHKplugin)

The Android app PWT (Personal Weather Tablet) is often used with the displayless consoles GW1x00, GW2000, WH2650
via their http custom server post (push) function to display their data on an (old or new) Andoid tablet.

(if table not fully shown: right click, open image in new tab)
 [ You are not allowed to view attachments ]
the WH2650 gateway console is not contained in this table. It can have/use the same sensors and number of sensors as the HP2550 console with firmware 1.7.2.
It is not sold by Ecowitt directly but mainly by resellers like Froggit, Steinberg Systems, Waldbeck etc. in Europe as 868 MHz models (see matrix on top of the thread).
E.g. Froggit WH2600Pro WiFi
each console can have the maximum number of each sensor type simultaneously connected ! (it's AND and not OR  8-))

per console only one of the outdoor temp/hum, traditional rain, wind and solar sensors will be shown
if more than one of these types are registered to the console, the below hierarchy is applied by the console
(this applies to the HP25x0, GW1x00, GW2000, WN19x0 and WH2650 consoles)

outdoor temp/hum: WH65/WS69 --> WS80 ..> WS90 --> WH32(-EP)
rain: WH65/69 --> WH40
wind: WH65/WS69 --> WS68 --> WS80 --> WS90
solar: WH65/WS69 --> WS68 --> WS80 --> WS90

The GW1000/WH2650 (firmware >= 1.7.4), GW1100, GW2000 (firmware >= 2.1.4) and WN19x0 (firmware >0 1.2.0) consoles can have a traditional (WH65/WS69, WH40) and a haptic/piezo rain gauge (WS90) simultaniously connected and synoptically shown. The HP25x0 consoles (firmware >= 1.8.0) can so far only show either or (traditional or piezo) with both connected.

13. the Ecowitt Gateway API (application programming interface) aka GW1000 API
the Ecowitt Gateway API (EW-GW API) is an interface which allows applications to retrieve data from an Ecowitt console/gateway which supports this API.
Currently (October 2022) the following consoles have the EW-GW API:
displayless consoles/gateways
- GW1000 (no longer produced)
- WH2650 WiFi (WH2600 successor gateway with WiFi - sold under different names by various resellers e.g. Froggit, Steinberg Systems, Waldbeck, ... mainly in Europe)
- GW1100 (GW1000 successor model)
- GW2000 (latest Ecowitt gateway, sold together with the Ecowitt WS90 outdoor array as GW2001 station, also available as single gateway/console)
- WH2685 (mainly sold as Ambient ObserverIP 2.0 module - Ambient restrictions apply, even though a GW1100/GW2000 deprived of their indoor T/H sensors would act as a WH2685 without the Ambient restrictions)
consoles with display
- WN19x0 consoles (lightweight console)

(there is one more console which has a similar API, the WS2320E console. The WeatherSmart for WiFi or WeatherSmartIP software for Windows PCs retrieves data from a WS230E (clone) console, displays it in the software user interface and stores/archives the data in a Microsoft Access database. Custom software could also retrieve data from this console when the API description is known - independent of the server OS. The WS2320E has only a limited not expandable number of sensors, while the EW-GW API supports all recently available Ecowitt and reseller clone console sensors including Ambient.)

The API serves various purposes:
1. request device information (device type/name, firmware version, RF reception frequency)
2. retrieve and add/change posting to weather networks (Ecowitt, Weather Underground [WU], WeatherCloud, WOW and a freely customized server address/domain, path, port and posting interval)
3. retrieve and add/change sensor calibration offsets or gain factors
4. register or disable sensors
5. retrieve information about registered sensors and their battery charge status
6. retrieve information of console/gateway runtime since last reboot
7. retrieve sensor readings (observations) on request
8. initiate a reboot of the console/gateway

The API is documented and released for public use by Ecowitt - latest version is 1.6.4.,1100%20WH2680,2650%20telenet%20v1.6.4.pdf
The documentation may not be easily readable by non-adepts without a certain level of software programming skills. Therefore we will explain its main functionality in the text below with examples.

Ecowitt provide an app (WS View Plus) which in its latest release can do all the above listed activities (1. - 7.) with all recent sensors/sensor arrays. The development of the legacy WS View app (without "Plus") has been discontinued and it can no longer retrieve data from or configure all sensors - especially the WS90.

The app - or a custom developed program with an integrated network socket - can communicate with the respective consoles via the API using TCP protocol via port 45000 by sending defined commands and reading the related response from the console through its API.

(CumulusMX, Meteobridge, Weather Display and weewx have drivers or inbuilt software portions which can inquire the Ecowitt Gateway API and receive and process the API response)

For the data retrieval there are mainly two commands which would trigger a console response regarding current preprocessed weather sensor observation data:
2. CMD_READ_RAIN (this command was introduced to cover the data from the haptic/piezo rain sensor built into the WS90 sensor array ["Wittboy"])
(battery/signal data for all sensors/sensor arrays can be read via the command CMD_READ_SENSOR_ID_NEW)

The CMD_GW1000_LIVEDATA command sent as a hexadecimal (HEX) byte sequence to port 45000 of the gateway (IP address) triggers a variable length console/API response which contains the actual, current data of all sensors connected/registered with that console. The variable length is defined by the number and type of sensors connected to the console.

Below the decoded byte sequence of the retrieval request and of the API response:
The general data exchange format is:
Fixed header, CMD, SIZE, DATA1, DATA2, , DATAn, CHECKSUM
Fixed header: 2 bytes, header is fixed as 0xffff CMD: 1 byte,
Command SIZE: 1 byte, packet size,counted from CMD till CHECKSUM
DATA: n bytes, payloads,variable length

CMD_GW1000_LIVEDATA: 0xFF 0xFF 0x27 0x05 0xnn (FFFF = header, 27= Command, 05 = size, nn = CheckSum)
API response: (FFFF = header, 27= Command, 0096 = payload size, payload, checksum  [HEX 96 = DECIMAL 150])
[payload(s) means the observation related data sent by the console including administrative data, e.g. sensor name codes,
or, from the logistics terminology, where the word comes from:
Header + Command + content size + checksum is the Container, the payload is the content of the container and its packing list]

the payload data has the following structure:
a marker or identifier of the sensor and the related data (the length of the data portion is defined in the API description)
e.g. 0x01: Indoor Temperature; related data: multiples of 1/10 of the Indoor temperature in centigrades hexadecimally coded in two bytes

below a real-life API response from a GW1100 gateway - the list of connected sensor is shown under the response and the decoding description
(a software program for decoding the API response must identify the observation (marker, identifier) and the related data following the marker.
this has been done manually below for a real-world API response)

inside this API response there is contained
- a WH32 as outdoor temperature and humidity
- the GW1100 indoor T/H and absolute and relative pressure
- the wind speed, maxGust daily, wind direction
- solar radiation and UVI
- 4 WH51 soil moisture sensors (channels 1-4)
- 7 WH31 extra T/H sensors (channels 1-7)
- 1 WN34L user defined temperature (channel 1)
- 1 WN35 leaf wetness sensor (channel 1)
- 1 WH55 waster leakage sensor (channel 2)
- 1 WH57 with daily lightning count, EPOCH time stamp (seconds passed since 01-Jan-1970) of last lightning occurrence and distance of last lightning
- 1 WH40 with all (traditionally measured) rain data from the interface
- 1 WS90 with piezo rain data (piezo rain data to be retrieved separately with the CMD_READ_RAIN command)
- 1 WH45 with PM2.5, PM10, CO2 data (actual and 24h) plus WH45 temp/hum
- 2 WH41 PM2.5 sensors (channel 1 and 2)

it may appear at first glance that the marker sequence is not really ascending and sort of chaotic - there is some inbuilt logic - but in order to decode one has to take the indoor sensors first and then the outdoor sensors.
The first markers 0x01, 0x06, 0x08 and 0x09 are the indoor temperature, indoor humidity, absolute air pressure and relative air pressure.
Then come the outdoor sensors 0x02 in ascending sequence (with a few exceptions  ](*,):  for an extra temperature there is a related extra humidity which starts counting after the 8th extra Temperature sensor; also the PM2.5 WH41 sensors are somewhat out of sequence - that's because of a historically grown API). The decoding software has to know this sequence for proper decoding. Also for the WH45 values the byte sequence, size and allocation needs to be known. A WH51 soil moisture sensor has always a corresponding WN34 sensor for its "neighbour/successor") - and the API allows for 16 soil moisture and 16 soil temperature (and 8 user defined) sensors, but the console firmware (so far) only allows for 8 WH51 soil moisture and 8 user defined sensors (WN34). At the end comes the max daily wind gust and the traditional rain data.
As theoretically all possible sensors could be connected to the console, all have to be checked for presence and if present for their observation data.
Therefore writing software for doing this decoding is quite a challenging and more complex job.

With the CMD_READ_RAIN command all rain data of connected rain gauges (maximum one traditional [WH40 or WS69] and one piezo [WS90] rain gauge) can be retrieved
CMD_READ_RAIN has the command code 0x57

a typical (real-life) API response is:

14. retrieving data from the Ecowitt cloud (

if you have an account at (the Ecowitt cloud), you can have your Ecowitt (or clone except Ambient) consoles post there in a 1 - 5 minute interval. The data is displayed on the dashboard and refreshed every minute and stored every five minutes. You can have more than one console post to the same account. The console (device) is identified and selectable based on its MAC address.
This data can also be retrieved from the cloud via the so-called Ecowitt cloud API (not to be confused with the Ecowitt Gateway API of the GW1000/GW1100/GW2000/WH2650/WN19x0 consoles via which data can be retrieved directly from the console inside the same local network subnet).

Data is kept in the Ecowitt cloud for different periods at different intervals:

-     5 minutes resolution data within the past   90 days
-   30 minutes resolution data within the past 360 days
- 240 minutes resolution data within the past 730 days
-   24 hours    resolution data since 2019.1.1

With a proper piece of software (or even manually), the data a console posted earlier can be retrieved by the help of an API key and an APP key - to be created in your account profile. Each one (API and APP key) needs to be created separately.
the generic https call(URL to be entered into your browser) is:

- you have an account at
- your console is registered at via your account
- your console posts to
- you have created an AP key and an API key in your profile
