I installed my HS200 today and outside the limited room to stuff the wiring in the box, everything seemed to go fine.  Had two black wires, white neutral and copper ground.  One posted up It connected easily to my Google home network and responds to commands or physical button push.  However the problem is the light hooked up to the switch is only half as bright as normal and when "turned off" it is still on, just at a dimmer level compared to when it is "on".   Ideas?
