HS220 not working with two gang
Have a two gang switch at the bottom of stairs. One of the switches controls the recess lights over the stairway. Those same lights can be turned off with another switch at the top of stairs.
The other switch in the two gang controls two recess lights in the family room downstairs. I can't get the switch to work at all for the downstairs recess lights. The HS220 smart switch is powered but it will power in the two downstairs lights.
