Hi There,
I’ve a room with multiple HomeMatic (Non-IP) Radiator thermostats and a wall thermostat. The are linked using a HomeMatic Group. Manually everything works fine.
Now I want to control the heaters using OpenHab. The Problem ist, that a group is read only, so I can’t write the SET_TEMPERATURE to the group.
Is there another way than sending the SET_TEMPERATURE to every member of the group? I’ve did that in the past, but it sometimes works and sometimes didn’t and I don’t know why?
