During the renovation of the last room in our house, I unfortunately forgot to lay a cable for the control of the floor heating.
The obvious solution is of course to switch the thermostats with Shelly relays and connect them via a Raspberry Pi Zero W using MQTT.
This ist the actual control software, which runs on a NodeMCU ESP8266. Communication also runs via MQTT.
Close your eyes and think of England.
Just a little bit of quickly hacked C source code.
