2. control heating circuit (C2 ) setpoint2 via Home Assistant.

Post by Thision9 »

Hello,


can anyone here give me a tip on how to control the 2nd heating circuit in Home Assistant?

I can use the OTMonitor to change the flow temperature using the “ C2= ” command.
But the service is not made available to me in Home Assistant.

Attached are pictures of the services that can be called up.
I can also retrieve data via MQTT.
