3 Way Switch Wiring Diagrams Mr Electrician
Light switch only has one black wire. So i have a switch that has one black load i tested it and it has 120v one white neutral and one red. Run 2nd wemo black wire to black wire from old switch. Smart switches use a neutral and a ground wire in addition to the line and load black wires. I would check that the load wire probably black is securely connected to the screw labeled load. Open the package of wire nuts and installation screws that came with the new light fixture. With only 1 black and 1 white they are both black as far as hooking up wemo.
