It clearly indicates the power input options (AC 85-250V/USB 5V) and the terminal connections for Neutral (NL), Common (COM), Normally Open (NO), and Normally Closed (NC) for each of the four channels. Use these labels for correct wiring.

Wiring Terminals:

• Input: Connect your AC 85-250V power supply or USB 5V to the designated input terminals.
• Output Channels (K1, K2, K3, K4): Each channel has terminals labeled NL, COM, NO, and NC.
• NL (Neutral Line): Connect to the neutral wire of your appliance.
• COM (Common): Connect to the live wire from your power source.
• NO (Normally Open): Connect to the live wire of your appliance for standard switching (appliance turns on when the relay closes).
• NC (Normally Closed): Connect to the live wire of your appliance if you need the appliance to be on when the relay is open, and off when it closes.

Ensure all connections are secure and insulated. After wiring, the device can be mounted in a suitable location, such as a lighting panel faceplate or within an electrical box.

6. Operating Instructions

6.1 Pairing with Zigbee Gateway

To enable smart control, the K32C ZG-005-RF Smart Switch must be paired with your Zigbee gateway.

1. Power on the smart switch.
2. Put your Zigbee gateway into pairing mode (refer to your gateway's manual for specific instructions).
3. On the smart switch, press and hold the 'Mode Switch' button until the indicator light flashes, indicating it's in pairing mode.
4. Once successfully paired, the indicator light will change or stop flashing. The device should now appear in your Zigbee gateway's connected devices list.

6.2 Using with Tuya/Smart Life App

After pairing with the Zigbee gateway, you can add the device to the Tuya Smart or Smart Life application for remote control and automation.

1. Open the Tuya Smart or Smart Life app on your smartphone or tablet.
2. Ensure your app is connected to the same Zigbee gateway.
3. Follow the app's instructions to add a new device. The app should discover the smart switch through the Zigbee gateway.
4. Once added, you can rename the switch and its individual channels (K1-K4) for easy identification.
5. You can now remotely turn on/off connected appliances via the app.

6.3 Setting Modes (Self-locking, Interlocking, Inching)

The smart switch supports different operational modes to suit various applications. These modes are typically configured within the Tuya/Smart Life app or through specific button presses on the device (refer to the full PDF manual for detailed button sequences).

• Self-locking Mode: Each channel operates independently. Pressing a button (physical or in-app) turns the corresponding appliance ON, and pressing it again turns it OFF.
• Interlocking Mode: Only one channel can be ON at a time. Turning one channel ON automatically turns OFF any other currently active channel. This is useful for applications where only one device should operate at a time.
• Inching Mode (Momentary): The channel turns ON for a brief period (e.g., 1 second) after a button press, then automatically turns OFF. This is ideal for momentary actions like opening a garage door or triggering a pulse.

6.4 Voice Control

Once integrated with the Tuya/Smart Life app and linked to a compatible voice assistant (e.g., Amazon Alexa, Google Assistant), you can control your appliances using voice commands.

1. Ensure your Tuya/Smart Life app is connected to your voice assistant service.
2. Use commands such as:
   • "Alexa, turn on [Appliance Name]"
   • "Hey Google, turn off [Appliance Name]"

7. Maintenance

To ensure the longevity and optimal performance of your K32C ZG-005-RF Smart Switch, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe the exterior of the device. Do not use liquid cleaners or abrasive materials.
• Environment: Keep the device in a dry environment, away from direct sunlight, extreme temperatures, and high humidity.
• Firmware Updates: Periodically check the Tuya Smart or Smart Life app for any available firmware updates for your device to ensure you have the latest features and security enhancements.

8. Troubleshooting

If you encounter issues with your smart switch, try the following troubleshooting steps:

• Device Not Responding:
  • Check if the device is powered on and the indicator light is active.
  • Verify that your Zigbee gateway is online and functioning correctly.
  • Ensure the smart switch is within range of the Zigbee gateway or another Zigbee router.
• Cannot Connect to App:
  • Confirm your smartphone/tablet is connected to a 2.4G WiFi network.
  • Make sure your Zigbee gateway is properly connected to your home network and the internet.
  • Temporarily disable MAC address filtering on your router if it's enabled.
  • Try resetting the smart switch to pairing mode and re-adding it through the app.
• Voice Control Issues:
  • Ensure the smart switch is correctly linked to your voice assistant (e.g., Alexa, Google Assistant) via the Tuya/Smart Life app.
  • Verify the names of your appliances in the app match the names you are using in voice commands.
• Intermittent Connectivity:
  • The smart switch can act as a Zigbee router. If you have multiple Zigbee devices, ensure they are creating a robust mesh network.
  • Consider adding more Zigbee routers if your network coverage is weak.

9. User Tips

Based on general usage patterns and product capabilities, here are some tips for optimizing your experience with the K32C ZG-005-RF Smart Switch:

• Network Stability: For optimal performance, ensure your Zigbee gateway is centrally located and that the smart switch is within effective range. If you have a large home, consider using additional Zigbee devices that can act as routers to extend your network.
• App Customization: Take advantage of the Tuya/Smart Life app's features to create custom scenes and automation rules. For example, schedule lights to turn on/off at specific times or link the switch's operation to other smart sensors.
• Mode Selection: Carefully choose the appropriate operating mode (self-locking, interlocking, or inching) for each channel based on the connected appliance's function to avoid unintended operations.
• Labeling: Clearly label the physical buttons (K1-K4) or the corresponding channels in your app to easily identify which appliance each channel controls.
