If I have a smart TRV on every rad (bar one) then I don't need a main thermostat. If any TRV is calling for heat then turn the boiler on and provide some.
I don't know if this is how off the shelf stuff works but in theory I could build my own with some ZigBee TRVs, a WiFI relay and a Raspberry Pi.
I might do some extra detail like bedrooms are warm first thing in the morning on a school day to encourage teenagers out of bed but then cooler until they get home and go and do some homework (yeah right, just heat the telly watching room).
Depends on your boiler a bit. Some have fancy digital interfaces, mine just has mains present or not. Any mains relay rated at a couple of amps would work for me.
