here is how I wired up 4 way… was with previous hub almond, I am waiting for my st v2 to try it…
anyway the concepts are the same.
The key is to find the central switch. Basically there should be double traveler wires on that one. Usually it is the switch in the middle ie between the other two. This is because the electrician will have wired up a traveler or extra wire to each of the other switches on the sides… It is usually this way as this is the easiest way to wire it. You can confirm which are the traveler wires by using a multi meter and adding a temp extra piece of wire you have around and check resistence for connectivity between the traveler wires running for the central to the other switches. Anywway these are usually a different color than the normal wires… if not a different color you will have to do above to confirm (with power off obviously)
In my case my central or switch in the middle had 4 wires hooked to it not counting the ground… 2 black and 2 red.
The two reds were the traveler… This central switch will be your main (zwave) switch and the other two will be the add-on switches from GE.
All of the switches wired you will have the find the neutral… Usually a bundle of white wires in the back with a wire cap on. If it is a multi switch panel (ie more than one switch) use the correct bundle of white wires that has the wire in it from the same set of wires that the other ie blacks etc come from and goto your switch.
Once you locate your central switch wire the main not add-on switch this way… The white neutral from the bundle goes to the neutral (bottom left on the ge switch) Usually the bottom right on the original switch is the Line or hot wire. (usually a darker screw). I couldn’t tell from mine so used the bottom right… this goes to the line or bottom right on the ge switch… The other black goes to the load
(top right on ge switch)
The two traveler wires ( red in my case goto the traveler or top left (with tape on it) on the new switch. You can put one in each of the two holes
If nothing works initially the load and line wires (my two blacks) are swapped. (I had this) just swap them.
So dual travlers upper left, line lower right, load upper right, neutral lower left.
The other two switches are exactly the same and easier… Each gets one of the GE add-on switches with only 2 connections.
They original switches you are replacing should have 3 wires each not counting ground.
The red/alt color or traveler goes to the traveler on the add-on switch, the white neutral you get from the bundle wire group in the back goes to the neutral and the 2 black, or 1 blue and black that are the line and load, get wired together and you put a wire cap on them…
That is it… hope it helps.
