I ran the “TP-Link (unofficial) Connect” integration for 3 years without issues and decided to migrate to the new SmartThings native one 2 weeks ago.
Since then, every 5 days or so, Kasa seems to be logging me off the iOS app and asking me to re-enter my credentials. No big deal, I simply re-enter them.
The problem is that it seems to be executing the same procedure with SmartThings because my devices stop responding. If I go to Connected Services and click on TP Link, it will momentarily show a blank page for maybe half a second and come back to the main menu. My guess is that Kasa is requesting the credentials again and SmartThings does not do so?
The first time this occurred, I deleted the TP Link connected service and added it back. It took me over 1 hour to set everything back (automation, pistons, home bridge, iOS home, etc).
Now that this occurred a second time, no way I’m doing it again.
I tried: rebooting the SmartThings hub, restarting my iOS app, logging off both iOS apps (SmartThings and Kasa), no success.
