This function app allows you to get the data directly from your own PWS (personal weather station) and publish this to MQTT. So this does NOT require that you register your PWS to cloud accounts, like WeatherUnderground, Ecowitt, WeatherCloud, WOW (takes weeks to get key), etc, or the use of WeeWX (extra software).
This configuration will directly capture the data from your weather station!
Special thanks to Xorfor who has created the HA-PWS (and previously the Domoticz-PWS-Plugin) project initially. This PWS2mqtt project is inspirated by him and is using his calculations.

- Your PWS needs to be connected to your network. This can be done by using WS View app.
- Docker-Compose (or docker)
- You need an Azure functions container. More info: Azure Functions Powershell
- You need Mosquitto. More info: MQTT (Mosquitto) Or look at the example below
This function app, which can be ran in a docker container, will receive the data from PWS and publish it to MQTT. Look at the docker-comopose.yml for the docker setup that contains:
- Azure Functions container
- Mosquitto container
- Download the Function Apps folder to '/home/{USER}/Function Apps'
- Download the .env.azfunc file next to your docker-compose.yml file
- Update the .env.azfunc file with its environment variables (like MQTT server, username, password, etc)
- Add MQTT sensors to HA
- This requires the HA MQTT integration
- Create dummy devices (see dzVents script for details)
- Goto your Domoticz
- Click hardware
- Add hardware
- Enter a name (for example: weatherStation)
- Type: 'Dummy (Does nothing, use for virtual switches only)'
- On your created dummy hardware click: Create virtual sensor
- Name: PWS Indoor climate
- Type: Temp+Hum
- Do those previous steps (from: 'Create virtual sensor') for every device you would like to have (check the dzVents script for details)
- Download and add dzVents script to your dzVents script folder (domoticz/scripts/dzVents/scripts/PWS_update_weatherStation.lua)
- Update idx values in dzVents script conform created virtual sensors
- Add JSON.lua to your domoticz folder (domoticz/scripts/lua/JSON.lua)
- Enter DomoticzInTopic variable in .env.azfunc (Default value: "domoticz/PWS2mqtt")
In general, if the station is supplied with EasyWeather software (version 1.4.x, 1.5.x, 1.6.x), it is likely that the station will work with this HA Configuration!
If supported by your PWS, connect your PWS with WS View Plus (and also the 'older' WS View or WS Tool) to your router by wifi, so that your PWS can upload weather data.
- Install
WS View Pluson your mobile device - , or
WS View - , or
WS Tool - Follow the instructions to connect your PWS to your router
- Goto to Device List in Menu and choose your PWS
- Click on Next until you are on on the
Customizedpage - Choose
Enable - For
Protocol Type Same AschooseEcowitt- With Ecowitt the data will be send with a POST. Wunderground is using a GET, which is not supported by this solution.
