core: Problem setting up Velbus integration

The problem

I can’t fully set up the Velbus integration in Home Assistant.

When trying to add the integration i get an “unknown error has occured” message after which it is added, but with the perpetual state of “Initializing”. Most of the velbus modules are then usable in Home Assistant, but none of the services that the integration should provide.

It takes a long time to get to this point as it is waiting for modules the whole time before giving up. At this point the log is filled with error messages whenever something is changed (eg on/off) but most of the thing work.

If i now restart Home Assistant none of the linked devices work anymore and a remove/add of the integration is needed.

What version of Home Assistant Core has the issue?

2022.11.4
