This is the power that should light up your light, but obviously it can’t because the load on your switch isn’t connected. However, when the switch turns on, it tries to send “full power” along the load line. However, if it was, your light would always been on because it’s always sending some juice along that neutral line. This isn’t enough juice to light up your light though. The switch sends a trickle of power down the neutral, just enough to keep the Z-wave radio going. Instead of sending out power along the load though, you are sending neutral along the line. One is line coming in, one is load going out. First, as was linked above, I think this is a good pictures of what you have going on:Īs you can see here the black and white in the switch block really aren’t black and white, they should be black and black. Thanks for any help/advice.īest I think I know what’s going on here. Has anyone else faced this problem? Is there a solution at the switch-box, or am I going to have to re-wire from the ceiling down through the wall (I’ll probably live without the ceiling light before I do that!). I thought I might be able to resolve the situation by running a lead between the Load and Neutral terminals on the Jasco switch, but this results in the ceiling light coming on briefly for a moment, and then going out, which is followed by normal operation of the two Z-wave tethered floor lamps. The problem is that the ceiling light is no longer operable. The switch powered on and controls the two floor lamps with Z-wave plug-in modules perfectly. I installed the switch anyway, hooking the white lead to the Neutral terminal on the Jasco switch, and the black lead to the Line terminal. What I found when I opened the switch-box is that instead of having the required 3-leads (load, line, and neutral), the switch was wired with only 2-leads (line and neutral apparently). My goal was to extend the capability of the switch to control the ceiling light, as well as two additional lights controlled by Z-wave plug-in modules. I bought this switch from Amazon, which I’ve used to replace the in-wall light switch in my office, which originally controlled only the ceiling light.
