Thanks, I understood that.
The breaker box is outside on the side of the garage.
In the garage I'm using a flour light/night light combo on a 3-pin app module which is plugged into the same receptacle as some computer equipment using an XPPF.
I have an overhead incandescent lamp using a socket rocket plugged into the same receptacle as the garage door opener.
I have an in-wall socket w/ incandescent bulb using a socket rocket, and this is on the same circuit as the sprinkler system.
There is a ms13a mounted on the wall in the garage.
The signalinc is plugged in at the laundry room which is inside the house from the garage.
I use an RR501 to detect the motion sensor. The RR501 was connected to the same socket as the flour light using a splitter, and that way the flour light got the signal, but not the incandescents. Then I moved the RR501 to the laundry room next to the signalinc. Now the incandescents get the signal, but the flour light does not.
I think i've seen it work a couple of times, but I think there must be something noisy on the line somewhere. Even the XPPF on the computer equipment didn't solve it.
