I'm trying to install a wemo dimmable smart switch to replace a regular switch. The original wiring pictured below is unlike the other 8 switches I replaced in my home. It looks like it's hooked up to two switches next to each other. One of the switches does nothing. The other controls the lights and dimms them.
When I remove the extra switch from the equation and just have the white wire and the red wire hooked up to a regular switch with the black wire unattached the switch still works like it should. This tells me that the white wire is live? I tested it with an mtool and it does buzz. When I insert the smart switch white to white, red to red, black to black and green to metal frame does nothing. However, I can rearrange the wires where regardless of if the switch thinks it's on or off the lights remain on. So the questions are:
- Is the black wire neutral? If not, what is it?
- Could the switch be defective or is this wiring conducive with an always on possibility?
- Is there a wiring configuration that would actually work?
