Random log debug lines, started in the past week

Sorry if this is the wrong place to post. Been seeing this in my log for the past few days. Not sure if it showed up after the update or before. Been having some issues with lights turning off the instant i turn them on either with app or switch. Anyway, any assistance is appreciated.

Theses don’t look like errors, but network status messages. This one is from your roku.

This is a samsung device

and this one is from cisco

It doesn’t look like light bulbs are in these logs

Thanks for the info. I guess the ST just picks up chatter from other WiFi devices. Odd that I never saw this before, maybe related to update after all. I guess nothing to worry about. Now if I could just get ST to pick up all the things I actually want it to pick up, then I’d be in good shape. Thanks again. I’ll check the router MAC table from here out if I need to identify anything.
