Hi @

please enable debug logging, restart the integration and download and provide the log file after the issue occur again.

Further please download and provide the diagnostics data for this integration.

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.

thx 👍

Further question - is this the only occurrence of a "referencing a non existing via_device" message for the fritz integration, or are there more?
