HS200 switch works but light won't turn on
We hooked up our smart switch and there is power going to the switch. We were able to connect it through the app, but the light won't turn on. The switch being replaced operates the porch light and two carriage lights. There is another regular switch in the same box that we did not replace and it operates the inside foyer light. Our house was built in 2000. We see two black wires and a red wire coming out of the box. The cooper ground wire is connected in the back of the box.
