I have electric underfloor heating in my consrvatory.
I could never get the previously installed (dumb) thermostat to work well enough.
So, I replaced the thermostat with a z-wave switch (fibaro)
Then I added a couple of temperature sensors to the room and wrote an app to control it all
I aggregate the temperatures from the sensors to set a ‘virtual’ temp device and use the readings from this to control the fibaro to turn the heating on/off
One thing I also did is use one sensor on the window, this gave me a reading of how cold the metal is (so if it’s colder outside the aggregation changes)
It took a while to get the correct settings but now the conservatory is always ‘a nice temperature’ as my wife declares
