It appears I am not the only one with this issue. Out of nowhere my motion dimmer switches will just become unresponsive. If they were on at the time the lights are not able to be turned off and if it was off lights don't turn on. The only way to resolve is to press the "Restart" button. I refuse to do an RMA as I had done one once before for a HS200 smart switch that was a major hassle and cost me as much in shipping as a new device would. I know this is not a one off issue as others have reported and it has nothing to do with my setup. I have 10 other Kasa switches that aren't smart motion dimmers and they all work flawlessly (minus the HS200 that broke). Please do a FW update to address this extremely annoying bug.
