The switch off to the left does not have a neutral, but it is technically where power comes into the circuit through the common. This can be seen in the wiring diagram below. There is a lot of utilization of the 14-3 wire and using the white wire as a return instead of taking the neutral to another outlet box. The decision must have been made to save as much copper as possible when wiring my house. Original wiring diagram Note the neutral wiring coming in from another outlet I may actually be able to make it a bit easier, but it is working at the moment and I’ll let it stay for the time being. Below are both the before and after of the wiring. I also decided to purchase a few DD0SR-1Z switches, as they work with multiple locations easier than the DD0SR-DLC. Wiring up the foyer light that is controlled by 3 switches did require me to draw out the circuit. I have found it helpful to draw out the circuits to figure out where the power is heading.
The switch that is “closer” to the light or fan was replaced by a DD0SR-DLZ matching switch. As shown in the directions, you need to figure out which switch is first to get power. Fortunately, Leviton has a solution for these situations, unlike other smart switch providers. My next step was wiring up a 3-way switch for the hallway lights. If you don’t have success at first, try swapping the two hot wires – direction does matter with the Leviton switches. Single pole switches only involve wiring the ground, neutral, and the two hot wires. You can read more about my decision to switch here. The bedroom switches replaced the TP-Link smart switches I had. The only issue you may have is the lack of a neutral wire, in which case most smart switches will not work. There is only one light switch to change and a limited amount of things to go wrong. This was the easiest and most straight forward situation. My first experience was rewiring the light switches for the two bedrooms in my house. This was not my first work with Leviton smart switches. There are limited resources when it comes to installing the switches, and it can be a bit overwhelming if your wiring doesn’t match the instructions exactly. Continuing off of my post from before, I thought I would dive deeper on the subject of wiring Leviton smart switches in your home.
