Hello! We have about two dozen of the hs200(us) smart switches. Different hardware versions. Two on fw 1.0.11 and hardware version 5.6 VN1 have failed.

They had been working normally for over 8 months. One failed, I replaced it and didn't think much of it. Then the second one failed.

The green circle led and the wifi light both blink rapidly, if I press the reset button, the blinking leds stop, but then the lights on load flicker rapidly, once per second. The relay in the switch is heard rapidly turning on and off. The only way it stops is to shut off the breaker and remove the switch.

I haven't found a post similar, so I'm hoping this post will get some interest.
