This is simple thermostat specifically for the SonOFF NSPanel not the pro version. It is based on the Tasmota firmware and uses the built-in temperature sensor and relay to control the temperature in a room.
- Set the desired temperature
- control the relay to turn on/off the heater (L1)
- Display local outside temperature fetched from open-meteo.com
You need to install tasmota on the device first.

- Upload the autoexec.be file found in this repository. You can start a webserver with the following command if you have python3 installed:
python3 -m http.serverThen just note the IP address and port number and use it in the following command into the tasomta console: Note that you need to check the variables in autoexec.be and adjust them to your needs, for example the location of the outside temperature. You can re-upload the file after changing it.
