My smart action stop working today, Sunday 6/20. On App - Smart Actions screen it keeps trying to show my only action then ask to retry. I almost burnt my place down because of it. It turned on when I ask Siri but didn't turn off as programmed in Smart Actions, it happened twice today.
It happened also last year for a couple of times, that I notice, they said it was a problem with TP-Link server, it was down, hacked, or something. I'm surprised that Kasa/T-Link has this kind of problem with servers once they suppose to be experts on the subject. May be their server uses a ARCHER AX3000 like that one I returned after one day because it was a disaster, I couldn't keep it connected.
Anyway ..... proves that we cannot trust the Kasa Smart Actions for serious application.
