Im trying to create an a solution for room heating using a TRV, an external temperature sensor in the room and the floor nest thermostat to only heat certain rooms. I can use better thermostat to create a termostat that uses the room temp sensor with the TRV and run an automation when it changes to heat to set the nest themostat up to max to call heat from the boiler. What im struggling to work out is how to turn the nest thermostat back down only when all the TRVs are set to Idle or off. Is there a more elegant way of doing this? Thanks !
