- Gather necessary tools: screwdriver (Phillips and flathead), wire strippers, voltage tester.
5.2 Wiring Instructions
IMPORTANT: Turn off power at the circuit breaker before proceeding.
- Remove the existing wall plate and switch.
- Identify the wires: Line (hot), Load, Neutral, Ground, and Traveler (for 3-way installations). Use a voltage tester to confirm the Line wire is de-energized.
- Connect the Intermatic Smart Wi-Fi Switch wires to your home's wiring using the provided wire nuts:
- Black wire (Line): Connect to the incoming hot wire from the circuit breaker.
- Red wire (Load): Connect to the wire going to the light fixture or motor load.
- White wire (Neutral): Connect to the neutral bundle in the electrical box.
- Green wire (Ground): Connect to the bare copper or green ground wire in the electrical box.
- Blue wire (Traveler): For 3-way installations, connect to the traveler wire. For single-pole installations, cap this wire with a wire nut.
- Carefully push the wired switch into the electrical box. Secure it with screws.
- Install a standard wall faceplate (not included).
- Restore power at the circuit breaker. The switch's indicator light should illuminate.

8. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Switch does not respond (no power). | No power to the switch. | Check the circuit breaker and ensure it is ON. Verify wiring connections. |
| Cannot connect to Wi-Fi or Matter. | Incorrect Wi-Fi band, weak signal, or pairing error. | Ensure you are using a 2.4 GHz Wi-Fi network. Check Wi-Fi signal strength at the switch location. Re-scan the Matter QR code. Power cycle the switch (turn off/on at breaker). |
| Voice control not working. | Switch not linked to voice assistant or incorrect device name. | Verify the switch is successfully linked to your Amazon Alexa, Google Home, or Apple Home app. Check the device name in the respective app. Ensure your internet connection is stable. |
| Switch makes a clicking noise when operated. | Normal relay operation. | This is a normal sound of the internal relay engaging or disengaging and does not indicate a malfunction. |
| Blue indicator light is flashing. | Pairing mode or network issue. | If flashing slowly, it may be in pairing mode. If flashing rapidly or inconsistently, it may indicate a network connection issue. Refer to app for status. |
