IMPORTANT: While the Wemo 3-Way Light Switch can be installed by anyone, it is recommended to hire a professional electrician if you do not feel comfortable working with or you are not familiar with electrical wiring.
Tools required to install
You will need the following tools:
- Phillips screwdriver
- Standard screwdriver
- Wire stripper
- Voltage tester
Before you begin
To install your Wemo 3-Way Light Switch, you will need to work with your home electrical wiring. When working with electrical wiring, there is always a risk of electric shock. Before removing any existing light switches, shut OFF power to the circuit powering your light switch, the main circuit breaker, or the fuse panel of your home.
Once you have verified that the power has been turned OFF from the circuit you will be working with, you can begin removing your existing light switch and installing your new Wemo 3-Way Light Switch.
Removing the existing light switch
Step 2: Use your screwdriver to remove two screws that are securing the light switch to the gang box in your wall. Once the screws are removed, gently pull out your light switch to detach it from the wall. Do not unscrew any of the wiring at this point.
Step 3: Confirm that you have neutral wires in your gang box. These are typically white and are not connected to the light switch. A neutral wire is required to install your Wemo 3-Way Light Switch. If the neutral wire is not present, STOP the installation and consult a professional electrician.
Step 4: Use your voltage tester to confirm that there is no power in the neutral wires from any neighboring circuits. If your voltage tester reads positive of voltage, you may need to turn OFF additional circuits at your breaker panel or fuse panel.
Step 5: Remove the incoming AC line/load wire coming from your circuit breaker panel or fuse panel. This wire is usually black but, depending upon the wiring used, you may have a different wire color in your gang box.
Step 6: Remove all other wires connected to the existing light switch to remove it from the wall. Any wire nuts that are connected to the wires such as the grounding wire or the neutral wire should be removed.
Installing the Wemo 3-Way Light Switch
Step 2: Connect the BLACK line/load wire from the back of the Wemo 3-Way Light Switch to the wire you labeled earlier with the line/load sticker using a wire nut. This will supply power to your Wemo 3-Way Light Switch.
Step 3: Connect the BLUE traveler 1 and RED traveler 2 wires from the back of the Wemo 3-Way Light Switch to the traveler wires in your gang box. Usually, the colors of the traveler wires are red and black but you may have different wire colors in your gang box.
QUICK TIP: If you install a second Wemo 3-Way Light Switch into this circuit, take note of which wires you will use to ensure they match the connections on the second Light Switch. This will ensure proper operation of your Wemo 3-Way Light Switches.
NOTE: If you have a ground wire or ground screw in your gang box, it should be connected to the GREEN ground wire on the back of the Wemo 3-Way Light Switch. The ground wire is usually green or bare copper but you may have a different wire color in your gang box. The ground wire is not required so, if you do not have it available, simply cap off the ground wire using a wire nut.
