I have had this installed and working for about a year and a half.  All of a sudden it's stuck in a mode where it's clicking and circle light and wifi light are blinking in sequence with the clikcing sound . When I manually turn off the Kasa switch the clikcing sound stops but the circle light and wifi light are still blinking . No recent changes have been made to my home's electrical wiring and in the Kasa app the switch shows as offline
