Our old (circa 1970) house has a post light out front. The switch is in an inconvenient location and is thus never used, so I thought I'd drop in a smart switch - a Belkin Wemo, in this case - to replace the old one and just put it on a sundown timer.
Here's the old switch:
Only one of the switches on there was actually active.
Per usual with this old house, all three of the wires connected to that switch were black so I have no idea which any of the wires were. The only one I marked with blue painter's tape was the the third switch which was screwed on below the other two, which were attached opposite each other up top.
Through the usual trial and error I have found two configurations which will power the smart switch on - basically swapping the "load" and "power" lines on the Wemo switch.
My problem is that neither configuration will light the bulb on the post light up. The LED bulb we had out there, which worked fine on the old switch, flickers on and off faintly. A halogen bulb I swapped in didn't light up at all.
So I'm not really sure how to proceed. I'm familiar with lights that either light up or don't, but a light that is sort of on but not really is a new one for me.
Any thoughts and advice would be greatly appreciated. In case it makes any difference or would be useful, I do have a continuity tester.
