HS200 Installation
Looking for an explanation for this:
In the garage there are 2 single pole switches in the same box sharing power from the same wire. One switch controls the inside ceiling light and the other controls outside coach lights. I replaced the switch controlling the outside coach lights. It worked great. However, the single pole standard switch no longer worked to turn on the ceiling light. So I swapped the black wire connections to the Kasa smart switch. That resolved the problem. I had thought it made no difference which Kasa black wires connected to the black wires previously used by the standard singke pole switch.
Thanks!
