Viessmann integration

Configuration
1

Hello there,

I am having trouble with the Viessmann integration - again. It is the annoying “bad Gateway” error that I couldn’t resolve for two weeks until it worked for a week and now I am having the same trouble again. I restarted the Heat Pump, the communication module, my network hardware the integration and the raspi hosting my installation of home assistant but I cannot get it working. Can anyone give me a hint?

Please excuse my language but it is a real pain in the a**.

Regards,

Alex

Hi Alex, welcome to the forum!

I’m not using that integration; have you checked Viessmann ViCare - Home Assistant

Yap, excuse me for being imprecise: that’s the one I am using.

No problem, did you double-check the settings?
Did you check your HA logs?
Did you check the time settings of your system?
You could try by reinstalling the integration.

Thank you for your fast response even at the time of the day.

I did all that. I just don’t understand the “Gateway offline” error. (see below). It seems quite random whether the integration can connect to Viessmann or not. The outages always came out of the blue.
I am working towards getting even more data through the CAN-Bus which the heat pump provides so that I can avoid the cloud. Until I get this running I was hoping to find a solution for this recursing error.
