I've been having issues with all my bulbs, I have two KL130's, and a KS103 v2 that... turn off for a moment, and right back on all at once together. Sometimes it happens occasionally, like once a night, but tonight it's been happening several times an hour. Everything is up to date in the Kasa app. Everything in my house is always stable, no brown outs, no network outages, they're on different circuits.
I don't mind so much not being able to use the plugs for anything state sensitive (I had gotten a smart powerstrip for my home theater equipment but it also cut power randomly and then everything had to get turned back on), but it's mighty weird.
