I've had a number of HS210s installed around the house for several years with no issues. Yesterday I noticed one had a wifi indicator that was flashing orange/green. I pressed the button to turn on the lights and they started cycling on and off once per second. The switch is unresponsive to the reset button, no matter how long I hold it. Cycling the power to the switch didn't change anything. Even rebooted wifi just in case. Nothing has made a difference. Failed switch?
