Reading up more it seems it should work in the gang box. This is a one-pole switch though there's a 3-pole in the gang box with it.

Here is my situation.

Previous switch:

• Had one live black wire that came from the next switch over and wrapped around the load screw and CONTINUED into the box. Just one continuous wire with the middle stripped out around the screw.
• Had one neutral BLACK (not sure why it isn't white) wire coming from the box into the neutral screw
• Wasn't grounded.

HS200 installation:

• Connected the two black HS200 load wires to the stripped out load wire using a pig tail (was kind of difficult given the continuous wire).
• Connected the black neutral wire to the HS200 white neutral wire.
• Found a copper wire and grounded to the green HS200 wire.

The circuit works now (the other two switches in the gang work). However, when I turn on the HS200 only a small glow on the first of two bulbs appears. The Wifi is fine, and I've tried it on two HS200s with the same result. Something appears to be wrong with the wiring I did.

Chat support told me to call an electrician, but that would cost 3 times what the switch costs so I would just send back the switch. Any ideas?

Thanks in advance!
