2. Important Safety Information

• Electrical Safety: Installation should be performed by a qualified electrician or a person with a thorough understanding of electrical systems. Always turn off power at the circuit breaker before installation or maintenance.
• Compatibility: This switch is designed for standard on/off control only. It is NOT compatible with dimmable bulbs or fixtures. Attempting to use it with dimmable bulbs may cause damage to the bulbs or the switch.
• WiFi Network: The smart switch operates on a 2.4GHz Wi-Fi network only. It is not compatible with 5GHz Wi-Fi networks. Ensure your router supports 2.4GHz.
• Wiring: This switch supports both neutral wire and no neutral wire (single fire) installations. Refer to the wiring diagrams carefully.
• Not a Traditional 3-Way Switch: While it offers 3-way control via multi-control methods (app, remote, voice), it does not function as a traditional mechanical 3-way switch requiring traveler wires between two switches.

4. Setup and Installation

4.1 Wiring Instructions

WARNING: Ensure power is OFF at the circuit breaker before beginning any wiring.

This smart switch supports two wiring methods: with a neutral wire or without a neutral wire (single fire). Identify your home's wiring configuration before proceeding.

Figure 3: Wiring diagrams for Neutral and Fire Line (left) and Single Fire (right) installations. A capacitor is required for single fire wiring.

1. Turn off power: Locate the circuit breaker controlling the light switch and turn it OFF. Verify power is off using a voltage tester.
2. Remove old switch: Carefully remove the existing wall plate and unscrew the old switch from the wall box. Disconnect the wires.
3. Identify wires: Identify the Live (Line), Load, and Neutral wires (if present). For single fire wiring, you will only have Live and Load.
4. Wire the Smart Switch:
   • Neutral and Fire Line Wiring: Connect the Live wire to the 'L' terminal, the Neutral wire to the 'N' terminal, and the Load wires to the 'L1', 'L2', 'L3', 'L4' terminals corresponding to your light circuits.
   • Single Fire Wiring: Connect the Live wire to the 'L' terminal and the Load wires to the 'L1', 'L2', 'L3', 'L4' terminals. A capacitor must be connected across the Live and Load wires of the light fixture for stable operation.
5. Mount the switch: Secure the smart switch into the wall box using the provided screws. Attach the glass panel.
6. Restore power: Turn the power back ON at the circuit breaker.
