Step-by-Step Installation: Bringing Your Leviton Decora Smart Switch to Life

Installing a smart switch can be a rewarding DIY project, but safety is paramount. Always remember, if you’re ever unsure or uncomfortable working with electrical wiring, it’s best to consult a licensed electrician.

Safety First:

• Turn Off Power: ALWAYS begin by turning off the power to your switch at the circuit breaker. Confirm there’s no power using a voltage tester before touching any wires.

Tools You’ll Need:

• Flathead screwdriver
• Phillips head screwdriver
• Electrician’s pliers
• Wire strippers
• Electrical tape
• Wire connectors
• Handheld voltage tester

Identifying Your Wires:

Before disconnecting anything, take a picture of your existing wiring. This can be a lifesaver if you get confused. You’ll typically encounter:

• Line (Hot) Wire: Carries power from the breaker.
• Load Wire: Carries power to your light fixture.
• Neutral Wire: Completes the circuit (usually white).
• Ground Wire: For safety (usually bare copper or green).
• Traveler Wire: (For 3-way setups only) Carries power between two switches controlling one light.

Wiring Instructions (Single-Pole Installation):

For a standard single-pole setup (one switch controlling one light):

1. Ground: Connect the bare copper or green ground wire from your wall box to the green wire lead on your Leviton switch using a wire connector.
2. Neutral: Connect the white neutral wire(s) from your wall box to the white wire lead on your Leviton switch.
3. Line (Hot): Connect the black line (hot) wire from your wall box to the black wire lead on your Leviton switch.
4. Load: Connect the load wire from your wall box to the red wire lead on your Leviton switch.
5. Secure & Test: Gently tuck the wires into the wall box, screw the switch into place, and restore power at the breaker. The status LED on the switch should blink green, indicating it’s ready for setup. Test the manual ON/OFF function. If it works, turn off the power again to install the wall plate.

Wiring Instructions (3-Way/Multi-Way Installation):

For 3-way or multi-way setups, you’ll install one main Leviton Decora Smart Switch and one or more “companion” switches (DAWDC or DAWSC). The wiring can vary, so always refer to the specific diagrams in your product’s instruction manual. Generally:

1. Identify the Line (hot) and Load wires. The main smart switch will usually be wired to one of these, and the companion switch(es) will use a traveler wire (often yellow with a red stripe on Leviton models) to communicate.
2. Follow the specific instructions for connecting the main smart switch and the companion switch(es), paying close attention to the traveler wire connections.
3. As with single-pole, secure connections, test, and then install wall plates.

Configuring with the My Leviton App:

Once wired and powered, grab your smartphone:

1. Download: Get the “My Leviton” app from your app store.
2. Account Setup: Create an account or log in.
3. Add Device: Follow the in-app wizard. For 2nd Gen Wi-Fi devices, the app often uses Bluetooth for a streamlined setup before connecting to your home’s 2.4 GHz Wi-Fi network.
4. Name & Customize: Assign a name to your switch, place it in a room, and explore advanced settings like fade rates and minimum/maximum brightness.
