This small plugin for Homebridge adds a temperature sensor. The temperature is the outside temperature measured by a Luxtronik2 based heat pump controller (Siemens, Novelan, Wolf, Alpha Innotec).
First follow the instructions to install Homebridge
This plugin can be installed using Homebridge Config UI X or manually by following these steps:
npm install -g homebridge-luxtronik2
Now you will have to setup your config.json for homebridge. An example is included in this repo, however users are encouraged to avoid manual configuration and use the UI instead. If you are using Homebridge Config UI X you can edit the configuration on the CONFIG tab.
A temperature sensor should appear on your iOS device as accessory in the "HOME" app.
