Volkszaehler API not working about core HOT 13 OPEN

Here you go...
home-assistant.log

from core.

volkszaehler documentation
volkszaehler source

from core.

you need to set the proper port in your yaml (seems to be 8081 in your case)

from core.

@mib1185 That does not work at all.

Neither XXX.XXX.XXX.XXX:8081
Nor `# Standard-VZ-Integration

• platform: volkszaehler
  host: XXX.XXX.XXX.XXX
  port: 8081
  uuid: "8d3353b0-1140-11ef-a931-df6ccdXXXXXX"
  name: "Volkszähler Verbrauch"
  monitored_conditions:
  • average
  • consumption
  • min
  • max`

works. The latter one throws:

is the error message every time (when trying XXX.XXX.XXX.XXX:8081 or port: 8081 or without port) the same?

from core.

No, the call with http://XXX.XXX.XXX.XXX:8081

produces this message:

Unable to fetch data from the Volkszaehler API`

When I try it with no port added, I do not even get an error. But there are no values put through.

When I compare the examples on the official integration page (https://www.home-assistant.io/integrations/volkszaehler/) with my config, it is pretty equal. Only thing that is different, I configured using an IP adress instead of a qualified hostname. But that worked fpr months now. Don't know what is different now and changed from 2024.6.2 to 2024.6.3.

Don't know what is different now and changed from 2024.6.2 to 2024.6.3.

last change in volkszaehler is 3 months ago, so there is no recent code change

from core.

this indicates that your volkszaehler may be return data in wrong format or the python-volkszaehler lib may needs an update to consider maybe new volkszaehler device firmware?

from core.

Please enable debug logging (when configured with the port: 8081 option), restart HA and provide the home-assistant.log afterwards:
To do so add the following to your configuration.yaml:

logger:
  default: info
  logs:
    homeassistant.components.volkszaehler: debug
    volkszaehler: debug

Note: it is better to drag the log into the comment (which will add it as an attachment) and not copy paste as it is hard to read logs in GitHub.

404 = "not found" ... it seems your volkszaehler has an issue - a quick search provide this forum post

from core.

Funny thing is, it worked until 2 days before wthout any changes. NEither has vzlogger or volkszaehler as such changed nor did my config. Only thing that changed was Home Assistant. Plus: The REST-Calls to vzlogger API work fine. Just the VZ integration doesn't...

from core.

And even more "interesting"... When I comment the port and only stick to the IP address, the result is:

But there is no values in my dashboards and not even in the developer tools...

I get an identical error message during integration:

I can confirm, the REST-Calls to vzlogger API work fine.
