WeMo Smart Light Switch User Manual

1. Introduction

The WeMo Smart Light Switch provides total control over your lighting. This device allows you to turn lights on and off from the wall, through a dedicated mobile application, or using voice commands via compatible smart assistants. Designed for versatility, the WeMo Light Switch supports both single-pole and 3-way circuit installations, requiring only one Smart Light Switch per 3-way circuit. It also enables the creation of automated schedules and timers for enhanced convenience and energy management.

2. Important Safety Information

WARNING! Risk of electric shock. Incorrect installation could be dangerous or illegal.

Always ensure that power is completely shut off at the circuit breaker before beginning any installation or maintenance. Multiple breakers and/or fuses may need to be shut off for safe installation. If you are unfamiliar or uncomfortable with electrical work, it is highly recommended to call a professional electrician.

This device requires a neutral wire for operation. If your electrical box does not contain a neutral wire, this product will not function correctly. Consult a qualified electrician to verify your wiring configuration.

5. Setup and Installation

Before beginning, ensure you have the necessary tools: a screwdriver, wire strippers, and a voltage tester. Always confirm the power is off at the circuit breaker before touching any wires.

5.1. Pre-Installation Steps

1. Turn Off Power: Locate the circuit breaker controlling the light switch you intend to replace and turn it off. For safety, consider turning off the main power to your home if unsure.
2. Remove Faceplate: Carefully remove the existing light switch faceplate.
3. Test for Power: Use a voltage tester to confirm that there is no power to any of the wires in the electrical box, including the neutral wire.
4. Photograph Wiring: Take a clear photo of the current wiring configuration before disconnecting any wires. This will serve as a reference if you need to revert the setup.
5. Identify Line Wire: The line wire (hot wire) typically carries continuous power. It is usually black and connected to a black screw on the existing switch. Use the provided black tape to label this wire.
6. Identify Neutral Wire: The neutral wire (usually white) is essential for the WeMo Smart Light Switch. Ensure a neutral wire is present in your electrical box.

5.2. Wiring the WeMo Smart Light Switch

The WeMo Smart Light Switch is compatible with both single-pole and 3-way circuits. The instructions below cover the general wiring process.

1. Disconnect Old Switch: Carefully disconnect all wires from your existing light switch. Straighten any bent wire ends.
2. Connect Line Wire: Connect the black wire from the WeMo Smart Light Switch to the labeled line wire (the one with black tape) from your electrical box using a wire nut.
3. Connect Traveler Wires (for 3-way setup): Connect the red and blue wires from the WeMo Smart Light Switch to the corresponding traveler wires from your electrical box using wire nuts.
4. Connect Neutral Wire: Connect the white wire from the WeMo Smart Light Switch to the neutral wire bundle (usually white wires twisted together) in your electrical box using a wire nut.
5. Connect Ground Wire: Connect the green wire from the WeMo Smart Light Switch to the bare copper or green ground wire in your electrical box using a wire nut.
6. Secure Connections: Gently tug on each wire nut to ensure all connections are secure.

5.3. Post-Installation Steps

1. Test Functionality: Before fully installing the switch into the wall box, turn the power back on at the circuit breaker. Test the switch to ensure it powers the lights on and off correctly.
2. Install Switch: Once confirmed working, turn off the power at the circuit breaker again. Carefully push the wires back into the electrical box, then secure the WeMo Smart Light Switch into the wall box with screws.
3. Attach Faceplate: Secure the new faceplate over the installed switch.
4. Restore Power: Turn the power back on at the circuit breaker.

5.4. Advanced 3-Way/4-Way Configuration Note

While the WeMo Light Switch cannot directly replace a 4-way switch, it can be integrated into a 4-way circuit. In a typical 4-way setup (three switches controlling one light), there are two 3-way switches and one 4-way switch. You can replace one of the 3-way switches in this configuration with a WeMo Smart Light Switch to make the entire circuit smart. This requires identifying the correct 3-way switch that has a neutral wire in its box. You may need to open multiple switch boxes to find the appropriate 3-way switch with a neutral wire.

8. Troubleshooting

• Switch Not Responding: Ensure the circuit breaker is on. Check the indicator light on the switch; if it's off, there might be a power issue or a loose connection. Re-verify wiring if necessary (with power off).
• App Connection Issues: Ensure your Wi-Fi network is active and the switch is within range. Try restarting your Wi-Fi router. If issues persist, try resetting the switch (refer to the WeMo App for specific reset instructions) and re-adding it.
• Voice Control Not Working: Verify that your WeMo account is correctly linked in the respective smart assistant app (Alexa, Google Home, Apple Home). Ensure your smart assistant device is online and properly configured.
