Integration fails to set up in 1.5.3

The integration fails to start after updating from 1.3.x to latest. Does this log tell you anything? I use this every day so hopefully we can sort it out :)

Then when I try to set it up again from scratch:

Config flow could not be loaded: {"message":"Invalid handler specified"}

Found a workaround. Downgrading to 1.3 and manually deleting all bang_olufsen entries from ./storage/core.config_entries in the HA dir seems to have fixed it and allowed me to set up the extension again.

Thank you for the bug report. Are you using and older release of Home Assistant? It looks like you are using a Home Assistant Core version older or equal to 2023.8, which is not compatible with the bangolufsen integration version 1.4 and above, since DeviceInfo is now located in homeassistant.helpers.device_registry and not homeassistant.helpers.entity. Nevertheless, the required Home Assistant version has now been updated to 2023.8 in release 1.5.4.

You know what, I'm confused. I experienced issues with this integration when I updated HA to latest the other day, and since I absolutely depend on it I decided to downgrade HA until I could find a solution. That didn't help however so I downgraded the integration too and finally got it working.

I'm now on HA 2013.10 and just installed bangolufsen-hacs 1.5.4 and everything works well, so I'm not sure exactly what went on. Might have been a perfect storm of unrelated issues. Anyway, works again! Sorry to waste your time, but thanks for this integration. It's so good.
