I installed the 2 HS210 and I am running into the following issue:
Turn the switch that has wifi light showig on switch on, the light turns on. Turn the same switch off, the light turns off. However now If I try and turn the other switch on, the light does not turn on.
It seems that 1 switch is acting as 'master' and only turns the light and the other light switch when turned on.
Attached are the wiring images for the 2 swithces. Any help on how to fix this will be greatly appreciated.
