I'm also seeing this.

This is an issue when for some reason a client gets wrongfully marked as being powered by poe. I haven't figured out what characteristics that makes this happen. It is also problematic to do since it doesn't happen too often and what is needed is the snapshot of the client and device at the time of creating the entity.

A poor work around is to disable and then enable POE control to get rid of the faulty entities. But I think it will not be a part of hass until next release 0.109

@bdraco would you mind investigating this yourself? There must be some data in the client that can be used to not create a poe switch

[bdraco]

I forgot I even opened this. I haven't had a chance to get unifi re-enabled since the UDMP switch over. I'll take a look as soon as I can.

[Kane610]

There is no rush. This issue has existed for a long time, it is hard to catch it in the act and I've prioritised improving other aspects of UniFi.

[bdraco]

I just re-enabled and I haven't seen this pop up. It used to stream down the log. I'll report back in a few days to so if it happens over time.

[bdraco]

No longer happening

[Kane610]

Not impossible that it will come back. I'd be surprised if I solved it earlier this year 🤪
