Boiler control from radiator valves only? (No main thermostat)

Hi, just joined.
I’m looking to control my house heating, I want to use a switch controlled from my phone to turn on the boiler. From then on I want the temperatures to be controlled solely by the radiator thermostats. So no main thermostat. So if no radiator valves are on then it needs to know to turn the boiler off until a thermostatic valve opens again.
Is this possible with SmartThings?

Welcome! :sunglasses:

What country are you in? The device selection does vary somewhat.


check out the stock smart apps - virtual tremostat it can be used to turn on or off a switch based on temp

Sorry I couldn’t reply since Saturday as my account got blocked, no idea why!
