Hi @Kane610
Thanks for trying to improve the Unifi integration

With regards to the issue about unnamed devices being continuously added to HA, I never saw any proper solutions.
However I would like to share an idea with you.
Would you be able to add an option to only add in HA devices which are manually set in Unifi?

Yes, my thought is to move over to explicit selection of clients, I might add back an add-all option but that will be with the acceptance of issues like this.

This will also help adding more entities from clients as the user gets only from a select few.
