5. Installation
Before beginning installation, ensure the power is OFF at the circuit breaker. This smart switch supports both neutral wire and no-neutral wire configurations.
5.1. Wiring Diagram: No Neutral Wire Required
For installations without a neutral wire, a capacitor must be connected between L1 and the Neutral Wire (if available in the fixture) or across the light bulb. This is crucial for stable operation.

Safety Notice for No Neutral Wire:
- Cut off the power before installation.
- No neutral wire is required at the switch box, but a capacitor must be connected to L1 and the Neutral Wire (typically at the light fixture).
5.2. Wiring Diagram: Neutral Wire Required
For installations with a neutral wire, connect the neutral wire to the 'N' terminal on the switch. This provides a stable power supply for the smart functions.

Safety Notice for Neutral Wire:
- Cut off the power before installation.
- A neutral wire is needed to power the switch.

6. Setup and Pairing
This smart switch requires a Matter-enabled hub for full functionality and integration into your smart home ecosystem.
6.1. Matter Enabled Hub Requirement
A Matter-enabled hub (e.g., Apple HomePod, Google Nest Hub, Amazon Echo with Matter support) is required to connect and control your Matter devices. Matter devices can work with any Matter-certified ecosystem simultaneously without requiring you to choose a single controller, platform, or app.

6.2. App Pairing
You can pair and connect the switch by scanning the QR code located on the device using the Apple Home app, Google Home app, or Tuya Smart/Smart Life app.
- Ensure your Matter-enabled hub is set up and connected to your home WiFi (2.4GHz network).
- Power on the smart switch after installation.
- Open your preferred smart home app (Apple Home, Google Home, Smart Life, or Tuya Smart).
- Follow the app's instructions to add a new device. Look for an option to "Scan QR Code" or "Add Accessory."
- Scan the QR code printed on the smart switch or its packaging.
- Follow the on-screen prompts to complete the pairing process, including assigning the switch to a room and naming it.


7. Operating Instructions
7.1. APP Remote Control
Once paired, you can control your smart switch from anywhere using the connected mobile app (Apple Home, Smart Life, or Tuya Smart). Turn lights on/off, adjust settings, and monitor status remotely.

7.2. Voice Control
Integrate your smart switch with voice assistants like Siri, Google Assistant, and Amazon Alexa for hands-free control.
- Siri: "Hey Siri, turn on the matter switch."
- Google Assistant: "Google, turn off the matter switch."
- Alexa: "Alexa, turn on the [switch name]."


7.3. Timing Control
Use the Smart Life or Tuya Smart app to schedule your lighting routines. Set timers for lights to turn on or off automatically.
- Countdown: Set a countdown for lights to turn off (e.g., "Turn off bedroom lights in 20h 50m").
- Schedule: Create daily or weekly schedules (e.g., "Turn off bedroom lights at 10:00 PM").

7.4. Group Control
Create groups within your smart home app to control multiple switches or lights simultaneously with a single command or tap.

7.5. Backlight Switch On/Off
The switch features soft indicator lights for easy visibility. You can configure the backlight status through the app settings to turn it off, ensuring it doesn't disturb sleep at night.

7.6. Restart Status Definition Function
Define the switch's behavior after a power outage. You can set it to automatically turn 'On', 'Off', or revert to its 'Last Status' when power is restored.

7.7. Sharing Function
Share control of your smart switch with family members. This allows everyone in the household to manage the lights from their own devices.

8. Maintenance
- Keep the switch clean by wiping it with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ensure the switch is not exposed to excessive moisture or extreme temperatures.
- Periodically check for firmware updates through your smart home app to ensure optimal performance and security.
- If the switch becomes unresponsive, try restarting it by cycling the power at the circuit breaker.
9. Troubleshooting
- Switch not responding:
- Check if the circuit breaker is on.
- Ensure the switch is properly wired according to the installation diagrams.
- Verify your home WiFi network (2.4GHz) is active and the switch is within range.
- Restart the switch by turning off and on the power at the circuit breaker.
- Cannot pair with app:
- Ensure your Matter-enabled hub is online and properly configured.
- Confirm your phone is connected to the 2.4GHz WiFi network during pairing.
- Try resetting the switch (refer to app instructions for device-specific reset procedures).
- Ensure the QR code is clean and clearly visible for scanning.
- Voice control not working:
- Verify the smart switch is successfully linked to your voice assistant (Siri, Google Assistant, Alexa) account.
- Check your internet connection.
- Ensure your voice commands are clear and match the device name in your smart home app.
- Lights flicker or don't turn off completely (No Neutral Wire setup):
- Ensure the capacitor is correctly installed between L1 and the Neutral Wire (or across the light bulb). This is critical for low-power LED loads in no-neutral setups.
- Verify the load power of your lights is within the specified range (LED: 5-150W/gang).
10. User Tips
- For optimal performance and stability, especially with low-wattage LED bulbs in a no-neutral wire setup, ensure the capacitor is correctly installed.
- Utilize the group control feature to manage multiple lights efficiently, such as all lights in a living area or all bedroom lights.
- Experiment with the "Restart Status Definition" to find the most convenient power-on behavior for your preferences after a power cut.
- Regularly check for app and firmware updates to benefit from new features and improvements.
