Hi there, today I started my 2nd Raspi with HA for experimental purposes. I do have a Viessman Heating control in my network and it was subsequently proposed for integration. However reading HA’s integration doc as well as Viessmans docs, I did not succeed. Has anyone ever integrated a Viessman device and hints how to? Any ideas much appreciated
Got a working solution proposal from the Viessmann-Community. Happy to share ist here:
