HS200 Switch - Randomly turns on any light bulb in a group of light bulbs instead of turning on all.
I just installed HS200 Switch which is responsible for controlling a group of 3 light bulbs in the Hallway. After installation, I have noticed that when I turn on the switch, some times all 3 light bulbs turns on and some times only 2 of them. Is their something wrong with the Switch? or is this a result of something going wrong at the time of instalation? Any urgent help would be apreciated.
