Every light switch in the house is a switchlinc and every room has at least one lamplinc. I did the 4 tap test today and every device flashed red. I thought I was supposed to see some green?

You are correct. Some devices should be blinking green. It's highly unlikely, although possible, that all the devices are on the same leg of the split, single-phase electric supply. Which device did you use to initiate the test? When you say "flashed red," do you mean an occasional red flash or continuous red blinking?

I used a lamp dimming module. All devices flashed red pretty much in unison.

Flashed red now and then or blinked continuously? (It matters.) Try moving the LampLinc to different outlets around the house.

Flashed red every second. I moved it around with the same outcome.

The color of the flashing reflects the wiring in the residence. With the circuits being on the same 120 v leg coupling may not be an issue. The same 4 tap test should be done from the PLM to see it is on the same 120 v leg.

 

Is there a comm issue being being evaluated with this 4 tap test?
