In my stairs and 2nd floor hallway, I have 3 switches that control 2 light fixtures. I’m trying to make this a smart lighting set-up with a Leviton DZ6HD-1BZ and two Leviton DD00R-DLZ’s.
I watched this video by Automate Everything, but his wiring is not quite the same as mine. I’m comfortable with electricity, but I’m not an electrician.
My current set-up:
Switch at bottom of stairs
Switch on 2nd floor at top of stairs (Outside the Office)
Switch on 2nd floor (Outside Master BR)
My attempt at drawing a schematic of the wiring
In this picture, the blue lines represent the white wires and green represents bare copper wires. The house was wired in 1992 and I’ve replaced a few switches already - the white wires are consistently neutral.
I assume that the two DD00R-DLZ’s will go at the bottom of the stairs and outside the master BR and that the DZ6HD-1BZ will go outside the Office.
I also assume that my wiring is similar to the wiring in Option #1 here. However, the only switch box in my set-up that has two Romex wires (represented by orange in my schematic above) coming into/out of it is the box outside of the office. Which leads me to a secondary question of: How is power getting into this lighting system?!
But, my main question is: How do I convert this to a smart set-up? Do I simply replace the switches at the bottom of the stairs and the master BR with the DD00R-DLZ’s? That process seems straight-forward.
What is happening in the box outside of the office? Why are the black wires connected together with a nut? How do I connect this wiring to the DZ6HD-1BZ?
Thanks for your time, I really appreciate any help you can give!
