Anyone else having issues with the integration atm? Its says error while initializing (German “Fehler beim Einrichten”). Logs are completly empty. No hint so far. Anyone can help?

732

Hello all,

I’m also having problems with the ViCare integration.

Everything had been working fine for months, then I noticed that the data was not updating.

Restarted HA…problem still there. Deleted then tried to reinstall the integration, but I get the message ‘unknown error occurred’ during the installation process.

I’ve regenerated the API key, but that hasn’t helped.

Any ideas?

733

I had to go back to an Backup 1 day prior to this failure, nothing else helped

734

I followed the suggestion in the repo (i.e. delete config/.storage/vicare_token.save) and now I can re-add the integration (and it works following a HA restart)

735

I tried this without success. Can I ask you to let us know what steps you did (delte what file?, reboot of underlying hw, or restart of HA only, etc) and in which order?

My integration stopped working at about 9h ago, in HA logs - Request failed with status code 500 and message "Internal server error".:

Fixed by deleting config/.storage/vicare_token.save and reloading integration.

This is how it worked for me…

(1) delete the vicare integration (I don’t know if this is strictly necessary)

(2) go to config/.storage/ and delete the file vicare_token.save

(3) re-add the vicare integration

(4) restart HA via the System menu

this fixed it for me as well. No need to remove the integration first.

739

No luck here. As soon as I re-add the integration I get an error. After restart the error does not disapear. The error log is empty.

740

Hi,
I only did steps 2 and 4. This fixed the issue for me. At least for the moment.

Hi Everyone. For some reason the data from my Integration is not displayed in the energy dashboard.
I get the error that the entities:

  • sensor.vicare_heating_gas_consumption_today
  • sensor.vicare_hot_water_gas_consumption_today

are not the expected device category. Any Idea what to do?

742

It’s an issue in PyViCare due to Viessmann API changes.
See:

743

Ok. So is this something which can be solved? Or would it be possible to build template sensors to solve this?

744

This worked for me too.

745

Hi guys,

It seems that I am doing something wrong. I succesfully configured ViCare integration for Viessmman.
Everything works as expected but it seems that I am not getting gas consumption sensor value.

Is it matter of configuration or simply I do not have them because my gas boiler doesn’t supply such information through ViCare API? I do not see it through ViCare app also.

746

If you don’t see it in the ViCare app it’s likely that your device doesn’t support this.
To get the full dump of what the API provides you can go to the Home Assistant ViCare integrations page and dump the diagnostics which is a JSON with the full API response

You are right. There is no any API parametar which provides any power and energy related data.
I have gas boiler V 200-W and it seems it doesn’t have these metrics.

Thanks

Hi, I don’t seem to have this folder. When try to reinstall I get “Unknown error occurred”. Any idea what i can do to solve this?

This is where it’s stored on HA OS. Not sure what setup you’re running Home Assistant. But the file should be in your config directory

Thanks, I got it working again. I had to look for it directly on the server, within the HA UI i don’t see it…
