IMPORTANT:
- The Wemo 3-Way Light Switch cannot be used in a circuit with dimmer switches. This will cause the Wemo to malfunction or not work at all.
- The Wemo 3-Way Light Switch can be used in a 4-Way circuit but cannot replace a 4-Way light switch. It can only be used to replace 3-Way light switches in this circuit.
2-Way Configuration
Using a single Wemo WiFi Smart 3-Way Light Switch, WLS0403 in a 2-Way configuration
Your Wemo 3-Way Light Switch can be used as a standard 2-Way light switch. In this configuration the Wemo 3-Way Light Switch will be the only switch in the circuit controlling the light. Since a second light switch is not being used, only the traveler wire 1 (blue) will be used in this configuration with the traveler wire 2 (red) capped off using a wire nut. Below is an example of how the wiring should be connected.
The configuration above requires the following electrical wiring:
- An incoming AC line wire from your breaker panel
- An incoming neutral wire from your breaker panel
- A line/load wire connected to your light fixture/load
NOTE: A ground wire or ground screw is optional. For instructions on how to install your Wemo 3-Way Light Switch as replacement of a 2-Way light switch, click here.
3-Way Configurations
Using a single Wemo WiFi Smart 3-Way Light Switch, WLS0403 with a “dumb” 3-Way light switch in a 3-Way configuration
The design of the Wemo 3-Way Light Switch allows you to use a single Wemo 3-Way Light Switch together with a standard “dumb” 3-Way light switch in a circuit to control a light. You will still be able to use the Wemo App to control your light as well as controlling manually from the Wemo 3-Way Light Switch or the standard 3-Way light switch. Below is an example of how the wiring is connected.
The configuration above requires the following electrical wiring:
Gang box 1
- An incoming AC line wire from your breaker panel
- An incoming neutral wire from your breaker panel
- Two traveler wires connected to the second gang box
- A neutral wire connected to the second gang box
Gang box 2
- A load wire to your light fixture
- A neutral wire to your light fixture
- Two traveler wires connected to the first gang box
- A neutral wire connected to the first gang box

Using two Wemo WiFi Smart 3-Way Light Switches, WLS0403 together in a 3-Way configuration
You can use two Wemo 3-Way Light Switches together in a 3-Way circuit, where both Wemo 3-Way Light Switches control the light. In this configuration, one of the Wemo 3-Way Light Switches will have the incoming AC power from your circuit breaker and the other Wemo 3-Way Light Switch will have the wiring that goes to your light. Both Wemo 3-Way Light Switches can be used to control the light manually or grouped together to control the light using the Wemo App. Below is the wiring example.

4-Way Configurations
Using a single Wemo WiFi Smart 3-Way Light Switch, WLS0403 in a 4-Way configurationThe Wemo 3-Way Light Switch can be used in a 4-Way configuration, but it must be used as a replacement for a 3-Way light switch. The Wemo 3-Way Light Switch cannot replace a 4-Way light switch. When using a single Wemo 3-Way Light Switch in this configuration, you will have one Wemo 3-Way Light Switch, a standard “dumb” 3-Way light switch, and a standard “dumb” 4-Way light switch.
The configuration above requires the following electrical wiring:
Gang box 1
- An incoming AC line wire from your breaker panel
- An incoming neutral wire from your breaker panel
- Two traveler wires connected to the second gang box
- A neutral wire connected to the second gang box

Using two Wemo WiFi Smart 3-Way Light Switches, WLS0403 together in a 4-Way configuration
You can use two Wemo 3-Way Light Switches along with a 4-Way light switch in a 4-Way circuit. In this configuration, one of the Wemo 3-Way Light Switches will have the incoming AC power from your circuit breaker and the other Wemo 3-Way Light Switch will have the wiring that goes to your light. All three light switches in the circuit will be able to control the light manually, or you can control the light using your Wemo App. Note that the Wemo 3-Way Light Switch cannot replace a 4-Way light switch.
