Im trying to set up so that my heaters can be controlled through Homey.
I see on the Homey page that there is a possibility of setting the temperature but I dont know how.
What do I need to use to use whats in this screenshot?
Use a compatible thermostat, like tado or Toon, and install the app for it.
Or install the vThermo app, then Homey can, combined with temperature sensor(s), function as a thermostat.
Note, I would recommend to use a smart thermostat, I think Homey isn’t stable enough to trust my heating system to it.
