Tried installing my second 3 way switch for my stairway light with another HS210. It lets me go through the setup process but then shuts off. No white ring light, Wi-Fi indicator, nothing. Have it hooked up to the neutral wire. Switched the HS210s around and each one acts the same in that location. The location is at the top of the stairs in a two gang setup with a separate 3 way switch for a different light. Any ideas why it won't stay on and work in sync with the other HS210?
Two HS210s, only one works.
