Hey, I realize this is a bit beyond the scope of Indigo, but I'm unsure where else I should turn.
What I'm running into acts a lot like a need for phase bridging, if that's the right term. I've got a big house and it was definitely originally wired by someone who was not a licensed electrician back in the 70's. We've had some professional work done and taken care of the biggest issues, for example the circuit that was wired into two different breakers so it stayed hot even when "its" breaker was turned off, but it is possible that some oddities remain undiscovered.
What I'm seeing is that some outlets respond to my PowerLinc when I put a module on them, and some do not. Now typically that could just be put down the need for bridging, and I admit that I haven't tested this really thoroughly. But what I notice is that when I've moved the PowerLinc to other outlets, this behavior doesn't change. In other words, the same outlets stay responsive when the PL moves. It seems unlikely to me that when I've moved the PL at least three times now, I've just happened to be on the same side of the circuit each time now.
Does that make sense? I can move a outlet module around a room and it works then it doesn't then it does, but wherever I put the PL, the same outlets work then they don't then they do. So I wonder if installing a bridge is going to fix this problem.
