4 Way Wiring deviating from Inovelli diagram

Trying to wire a Red On/Off with two White Aux switches and noticed my current wiring does not match any of the two scenarios shown in the wiring schematics section. It does come close to the Line/Load in the same box (with Neutral) but there are some deviations. Appreciate if anyone can assist

Inovelli diagram:


  • The 1st box only has two bundle of wires instead of three coming - one with red traveler wire and another just black & netural
  • The 3rd box only has one bundle of wire as expected however white (Neutral) and Red (Traveler) seems to be connected in reverse to the old dumb switch


Neutrals are not ever connected to a dumb switch (they serve no purpose with a dumb switch and should never be connected to one).

Not all whites are neutrals, especially in a switch box. A white connected to a dumb switch is serving as a hot – load hot in many cases, but always verify each wire’s purpose via testing before connecting anything. Do not ever rely on sheath color alone to determine a wire’s purpose.

gotcha in this case can I assume the white wire in the first box (first photo) is actually the traveler and the red wire the load to the lamp? I believe (but could be wrong) the load connector is usually on the top and the traveler across on other side.

Look at the switch. The BLK common screw will either be line or load on a 3 way switch. The two brass screws are travelers.

I think I may have something like this. Borrowed a AC voltage detector and found that the white wire, and not the black wire in box 1 is live. Now I wonder how I can wire the Red On/Off and with the aux switch properly :). Not sure if I can consider the black wire coming from the lamp to the first box as neutral?


Okay, so presuming that you are supposition is correct, you have a non-neutral in box 1. Put the Inovelli there as a non-neutral configuration.

Then, using two of the three conductors running to the other two boxes, send the hot and the traveler. The hot goes to the neutral terminal on the aux and the traveler goes to the traveler terminal on the aux.

thanks this worked
