I live in a 600 sq ft apartment and cannot get the switch to work properly. It turns on the light (sometimes) but seldom turns off light. My “Goodbye” and “I’m back” routines are set to turn off/on the light respectively but never work. I have two of the switches, tried both, tried excluding and re-adding, nothing works. Moved my hub (v2) further from wifi router but nothing working. Should note the switch works fine in the room where the router is. There’s also a straight shot down the hallway (i.e. No solid walls) to the problematic switch. Do I need a z wave repeater? Should that matter in an apartment this small? Hub is about 3 feet from router (just because that’s the only extra Ethernet cord I have). Should I move it further away?
