6. Operating Instructions
6.1 Manual Control
Simply touch the grooved buttons on the switch panel to turn the connected lights on or off.

The 2.5D Tempered Glass panel features a groove design for advanced and textured touch buttons.
6.2 App Remote Control
Once paired, you can control your lights from anywhere using the Smart Life/Tuya app on your smartphone.
- Open the Smart Life/Tuya app.
- Select your smart switch from the device list.
- Tap the respective switch icons (Switch 1, Switch 2, etc.) to turn individual lights on or off.
- Use the 'All On' or 'All Off' options for master control.

Control your lights remotely via the Smart Life/Tuya app on your phone.
6.3 Voice Control
Integrate your smart switch with voice assistants for hands-free control.
- In the Smart Life/Tuya app, go to the switch settings and select "Alexa" or "Google Assistant" to link your account.
- Once linked, use voice commands such as:
- For Alexa: "Alexa, turn on [Device Name]", "Alexa, turn off [Device Name]"
- For Google Home: "Hey Google, turn on [Device Name]", "Hey Google, turn off [Device Name]", "Hey Google, is [Device Name] on?"

Seamlessly compatible with Alexa, Google Home, Smartthings, and Alice for voice control.
6.4 Advanced Features
- Timing Function: Set schedules for your lights to turn on or off automatically at specific times. This is useful for daily routines or when you are away from home.

Set schedules in the app for automatic light control, such as 7:00 AM Light ON and 8:30 PM Light OFF.
- Signal Repeater: The smart switch can function as a ZigBee signal repeater, extending the range and stability of your ZigBee network by transmitting signals among other ZigBee devices.

The switch can act as a Zigbee signal repeater, enhancing communication between your gateway and other Zigbee devices like door sensors, smoke detectors, PIR sensors, water sensors, and gas sensors.
- 2-Way/Multi-Control Association: This feature allows a single light or group of lights to be controlled by two or more smart switches. Note that this function requires both switches to be connected to the network and configured within the app, it cannot be achieved through traditional wiring.

For 2-way/multi-control, both switches must be connected to the network and set up in the app; traditional wiring alone is not sufficient.
- Family Sharing: Share control of the smart switch with family members through the Smart Life app, allowing multiple users to manage the lighting.

Share control of the device with your family using the Smart Life APP.
- Backlight Control: The switch's backlight can be turned off via the app, which is useful for bedrooms or other areas where light might be disruptive during sleep.

Turn off the switch backlight in the app for a better sleeping environment.
7. Maintenance
- Clean the glass panel with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Ensure the switch is not exposed to direct sunlight or extreme temperatures, which can affect its lifespan.
- Regularly check wiring connections for any signs of loosening or damage.
8. Troubleshooting
- Switch not responding:
- Check if the main power supply is on.
- Verify that the wiring is correct and secure.
- Ensure the switch is properly paired with the ZigBee gateway and the app.
- Cannot pair the switch:
- Make sure the switch is in pairing mode (green indicator rapidly blinking). If not, long-press any button for 5 seconds.
- Confirm your ZigBee gateway is online and functioning correctly.
- Ensure your phone's WiFi is 2.4GHz during the initial setup of the gateway.
- Try moving the switch closer to the ZigBee gateway during pairing.
- Voice control not working:
- Check if the Smart Life/Tuya app is correctly linked to your voice assistant (Alexa, Google Home).
- Verify the device name in the app matches the name you are using in voice commands.
- Ensure your voice assistant device is online and connected to the internet.
- Lights flicker or don't turn off completely:
- This can sometimes happen with low-wattage LED bulbs. Consider using a bypass module (not included) if flickering persists.
9. User Tips
- Consistent Naming: Use simple and consistent names for your devices in the Smart Life/Tuya app to make voice control easier and more intuitive.
- Group Control: For multiple lights in one room, create a group in the app to control them all with a single command or tap.
- Automations/Scenes: Explore the automation features in the Smart Life/Tuya app to create scenes (e.g., "Good Morning" to turn on lights gradually) or set up routines based on time, weather, or other smart devices.
- ZigBee Network Health: Since this is a ZigBee device, ensure your ZigBee network has good coverage. Adding more powered ZigBee devices (like other smart switches) can help strengthen the mesh network.
