My KS220M is configured with motion detection disabled because it turns off after 30 seconds whether I am in the room or not.
If has functioned properly for days, turning on and off by the switch, by using amazon Echo/Alexa, and by using the kasa application.
However, it periodically becomes unresponsive. The switch has a lighted (white) circle on it. The switch fails to turn the lights on. The Internet applications fail to detect th switch.
Using Reset or Reboot fails to get the switch working. I've sat in the dark for 1/2 hour, looking at the forum, finding no help. As I type this email, the lights came on and the switch became responsive.
Go Figure. What was it doing for the last hour?!?!?
