I have kasa switches and everything is blocked on my firewall so they can’t phone home.

Overall they function fine. But I have 1 pesky switch that is constantly in a disconnected state (red light) no matter what I do. Every time I reconnect it it disconnects not too long later. It functions fine though, possibly because its a 3 way and the paired switch is fine.

I have another set of 3 way switches that have disconnected a few times but reconnecting them works just fine for a long while (years).

So my questions are, that pesky red light switch sounds kind of like your situation. When you say they reset themselves, do the lights go red?

Secondly, yours reset every 10 minutes? Most of mine seem fine. I’m not sure what’s different between our setups.
