Is it possible to switch a powerplug (any brand which works with Homey) on/off when a specific room in Evohome needs heating?
My case:
I have floor heating at the ground floor and radiators in the other rooms. At the moment the pump of the floor heating is always on which means that if one of the other rooms need heating the ground floor also will be heated along with the others.
When I can switch the pump off when the ground floor is already at the wanted temperature the other rooms get heated properly and the ground floor also stays at the correct temperature. Of course the pump need to be switched on when the ground floor needs heating.
These are the available cards of the Thermostat central controller in the IF/WHEN part of the flow. You should also add the evohome zones as devices. And look under the AND part for logic cards. Then you can select the card above and use the tags of the zone.
