I have an outdoor light that I would like to control with a smart switch and a hallway light that can be a simple switch. Previously, the two were controlled by a non-smart combination switch;

I would like them to be two separate switches. However, I am having trouble figuring out how to wire it.

I have restated the question to be more concise please find the diagram below of the problem.

I hope this is enough information for everyone. Please let me know if you need more information.

Below is an adaption on @Ruskus design, however when I supply power, only the Out door lamp gets power. I am suspecting the single pole switch is bad, unless my wiring is also incorrect.

***Update Update

My adaptation of Ruskus design works, I did have a bad single pole switch

  • How many switches do you have in the old design. Do they have 3 wires each ? Could you independently control the lights inside and outside?

  • In previous design there was a combination switch (two switches combined into one gang) that were able to control the lights indepently

  • Can you post photos of the inside of the box involved please? Jun 5, 2022 at 6:27
  • Before you do anything find the circuit barker and turn if off. Black wires are usually load, the white is neutral. The red is for bridge between the switches. The single pole switch black screw is for ground.

1 Answer 1


Lets try this based on my drawing

Ignore the red (Tape it) in the 3 wire cable

As usual the polarity for the lamps does not matter. The incoming is your fancy isolation cable with 2 wires.
