I wonder how this could have happened. We have three lights in front of our front door, one hanging above the front door, and two on the sides. I replace the light switch with a Kasa smart switch, and now something weird is happening. When I turn the switch on, the light above the door turns ON and the two lights on the sides don't. However, when I turn the switch off the light above the door turns OFF and the two lights on the side turn ON.
What could be happening here? How would this be "inverting"?
