I am trying the Inovelli NZW31, no luck so far.
I have installed the dimmer NZW31 in a single switch configuration to control 9 ceiling can LED lights.
I did pair it with the smartthings hub, however it doesnt turn on the light neither manually nor thru the app.
Blue LED light occasionally turns on/off, not sure if it is normal.
I did refresh the z-wave mesh, try excluding and pairing it back, removed the airgap - same thing.
Also, originally installing I switched hot/line, hope it did not toast the switch.
