Viessmann Vitocal 200-S heat pump

Hi all,

Does anybody have experience with connecting a heat pump from Viessmann to openhab? Is it possible?
For me it could be an option via KNX, but I would like to avoid byuing the Vitogate for 800€ (if I am not mistaken).
What about the Vitotronic binding? (heat pumps not mentioned there).

Many thanks in advance for any kind of help :slight_smile:

BR,
Tomas

Don’t know much about heat pumps but some viessman products had a while ago something called optolink service connector. You can check if out product has one. In that case you would spent about 20eu to buy some electronic parts and esp32/8266 and intergrate by yourself through this connector.

I have done it with my Viessmann Vitodens 200-W
