Have a few HS 200 that were working just fine. Changed my Wifi network, and obviously they all fell off. I have successfully gotten 3 back on the network, and two unsuccessful. Also have two HS220 that are refusing to reconnect and will not factory reset, Yes I hold the button for, 5, 10, 20, and 30 seconds, no difference. Reset the circuit breaker, and again reset the switch. still will not connect. Physically pulled the wires from the switch, and reset after reconnecting, still will not connect. Now the really weird thing is my phone sees the device broadcasting a signal, but the app does not.

Just about at whits end here.
