I have tried to find a very simple way to control a wallplugg connected to a heater using a temp sensor and the Setpoint element, so I do’nt need to use the thermostat in the heater…
I have the Temperatur and the switch working and the setpoint value but do I ned to have a rule or is there a simpler way?
Any examples appreciated 
You will need a rule - I posted an example in a thread a few days ago. See if you can dig that up, sorry I don’t have the link.
