I installed the virtual thermostat plugin, but I can't get it working somehow.
The installation itself worked out, I see the devices so it works as you can see in the attachement. Also the room temp is taken over correctly from the sensor
In the other attachement you can see my settings.
As heating switch I use a Eurotronic Spirit. The selected device is level device, which can have the status on/off or percentage.

But somehow the heating switch isn't set, it stays in his normall thermo controll

Anyone any ideas?

Ok found out some more. It seems that the thermostat of the eurotronic spirit is working against the virtual thermostat. One swithes on the other switches of again. My new problem is I can't get the mode to "manufacturer specific" I found some more threads with this problem but no real solution. Does anybody know more about this? Or won't this be possible?
