Last June I installed TWO (2) HS220 switches both in the same room, same wifi.
Connected to Alexa, worked perfectly.
Today ONE (1), only one, of the two switches stopped working, not only through ALEXA but through the APP.
The other, to make it clear, still is working through the app and alexa.
I did the whole gammat of things, reset switch to factory settings, blinking orange green,
Checked on Firmware being updated (remember I have one identical switch still working)
Hard forced closing of app,
At long last I got it connected on the app and it again lost the app to smart switch connection,
I did the whole thing again, also deleting the greyed out app, trying to install.
I am on wifi with data LTE shut off. I even did a power out to the switch. I get to the point that it is trying to find
the wifi. The wifi works with all other smart devices and with my android phone, perfectly.
All smart devices, including three other kasa smart devices work fine.
But the Kasa wifi when I try to connect it finds the network but indicates there in no internet connection,
which, as detailed above is NOT true. In trying to connect it will disconnect my wifi and pull open the
data mobile connection which I have turned off.
HELP? My conclusion is something is wrong in the little "brain" chip of the swtich.
