Is the a way via OpenHAB (or otherwise) to set the current temperature from a Homematic HM-TC-IT-WM-W-EU (Room Thermostat) to a Homematic HM-CC-RT-DN (Radiator Thermostat)?
Many thanks in advanced.
PS: Currently, I just adapted the current temperature offset in the Radiator Thermostat settings in the CCU2 settings.
Yes. I created a “direct link” (Direkte Geräteverknüpfung) between them. I did the same with the Door/Window contacts, to lower the set temperature while the window is open.
You can setup this link with the ccu2 WebUI, the Homematic configuration software or the Homematic manager.
