4-way options with 2 smart switches and 1 aux switch

Switches Wiring Discussion

I have a 4-way set of lights and I was wondering if it’s possible to run a setup with 2 smart switches and 1 aux switch for the three light switches? I have neutral wires in a standard new build wiring setup, nothing weird.

EDIT:

Perhaps by wiring the Aux and then binding the two switches. @rohan will jump in here.

So I assume you have two locations where you want to see the light bar and one location where you don’t. This is more complicated wiring that simply putting a smart switch in all boxes or a single smart switch and 2 auxes.

For us to tell you exactly how to wire this with your wiring, we’ll need to see photos of all of the switch boxes and switches as they are today.

Roughly, the way I would do this is as follows.

  1. Wire the two dimmers as normal with a line and a neutral and a ground of course. One of them should have the load wire in the same box. To that one, wire the load and the traveler wire. Call this the “primary”. You’ll have to set the “primary” to 3 way Aux mode in your hub.
  2. The “secondary” should have no load and no traveler connected to the switch, but the traveler wire may need to be connected inside the box via wago or wirenut as a pass through.
  3. Wire the Aux to traveler and neutral as described in the standard 3 way with Aux instructions.
  4. You’ll use bindings to bind the two smart switches together.
