I got one of these hoping to use it at the fixture. Turns out my circuits are not switch looped from what I can tell. It’s an old house with knob and tube wiring, so my switch is wired in series along the hot which then makes its way up to the fixture. All I have in the fixture is that incoming switched hot and the neutral. I believe this give me no options unless I can tap my wiring before it heads to that switch. The whole circuit is exposed on the attic but since it’s knob and tube i should probably not mess with that.
Hoping that someone here with a little more experience with wiring can tell me that I missed something or has another idea.
