@buckyswider Hi @Emil ! So I installed that beta Matter code on my Leviton plugs and switches...and VIOLA! They are now all advertising the proper tcp service all the time. (At least for the first 24 hours or so). So it seems like we are good. Presumably now the FLIC hub will never show these as "offline" again. Thanks for your counseling!
I do have another Matter related question that came up dealing with Leviton support. But I don't want to be guilty of "thread drift", so I'll start a new thread.
Thanks again!
