Tried to install a HS220 in the living room today, got power to the switch, no power to the lights.  There is an older dimmer to some other pot lights in the same gangbox, I noticed it was a no-neutral variety.  There is a  bundle of neutrals in the box, so I figured this would install fine.

After no success, I tested it in a gangbox that currently has a working HS200 switch (same switch but no dimmer, also requires neutral to install).  Same thing.  Power to the switch, wifi works,no power to the lights.  If i swap (what I assumed was) the line and load, I just have a non-responsive dead switch. I wonder if it is legitimately defective, or if I should try another brand that offers no-neutral install from here on out.
