So I know there are several threads regarding this topic but I couldn’t seem to figure out my situation based on those. If this thread needs to be merged with one of those will the mods please feel free to do so.
As the title says I am attempting to install a GE Z-wave switch and an Add-On Switch into an existing 3 way switch. Where I am confused is the wiring I have does not seem to fit any of the wiring diagrams I have seen.
My First Box has the following wires
Line (Black) - Hot Wire (Confirmed by voltmeter)
The Second Box has the following
2 Separate Black Wires that I’m assuming are the load wires but am not really sure. Neither one is hot
All the diagrams and instructions I have seen show the main switch being wired with -
Since the box with the hot wire (Line) doesn’t have a load wire I’m not sure what to do and haven’t even been able to get it wired to the point the switch would power on showing the LED indicator
Not sure if it matters but each of these boxes also have a separate dimmer switch neither of which are 3 way
In a conventional 2-switch (3-way) setup typically one switch will have hot come in to common (black or brass terminal) and the other two non-ground screws are both travelers (usually red and black, or red and white with black tape). The second switch has the two travelers from the first switch and the common terminal is connected to the light/ load.
As for GE’s specific setup, I am not sure. (I just installed a Inovelli smart switch (www.inovelli.com) in a 4 way setup in my house. Very useful, if your wiring supports. One switch for ~$30 and use the other ‘dumb’ switches vs the expensive GE setup.) In the Inovelli setup, it is not conventional wiring. You actually connect the second switch to the “traveler” terminal only (one traveler wire, not two). The additional 3 way switch is then used to connect to neutral. The Inovelli switch controls the input by putting out a very low voltage across the “traveler” terminal and using the second switch to turn the binary output off by shunting to neutral. When the traveler output is connected to neutral, the Inovelli switch knows the other switch has been flipped.
I realize I’m not directly answering your question, but hopefully this gets things going for you. If it is similar, you may consider turning one of the now unused traveler wires into a neutral connection if it does not exist in the remote box.
I’m setting up an Inovelli switch for a 3-way, and I have some “extra” wires. The smart switch works, but it turns off when I flip the slave switch. Now, I saw my house when it was being built, and I remember the wires being run horizontally through the walls between switches and outlets. What I’m hoping is this what I’m seeing here.
