Important Notes
- GLEDOPTO ZigBee devices (Zigbee/Plus/Pro version Products) require a compatible ZigBee gateway for smart app and voice control.
- If you do not have a ZigBee gateway, you can use a GLEDOPTO 2.4G RF remote control or wall switch to operate Plus/Pro Version Products directly.
- This device is only compatible with the GLEDOPTO 2.4G RF remote control and cannot be used with other brands' remote controls.
- The 2.4G RF Remote Control and Wall Switch are separate accessories and only work with Plus/Pro Version Products (they are not ZigBee devices themselves).
- There may be some compatibility issues with IK*E*A smart home systems at present.

Wiring Diagram
The controller supports three modes: WWCW (Warm White/Cool White), 2-wire CCT, and Dimmer. You can switch between these modes using the "Opt" button on the controller.

Detailed wiring diagrams for different LED strip types.
- 3 Wires CCT: Connect the V+, W, and C wires from the LED strip to the corresponding terminals on the controller.
- 2 Wires CCT: Connect the V+, W, and C wires from the LED strip to the corresponding terminals on the controller.
- Dimmer: Connect the V+ and V- wires from the LED strip to the corresponding terminals on the controller.
Pairing with a ZigBee Gateway
To enable smart app and voice control, pair your GLEDOPTO controller with a compatible ZigBee gateway (e.g., Tuya, SmartThings, Homey, Echo Alexa hub). Refer to your specific gateway's instructions for adding new ZigBee devices. Generally, this involves putting the gateway into pairing mode and then initiating pairing on the controller.
Pairing with GLEDOPTO 2.4G RF Remote Control/Wall Switch
If you are using a GLEDOPTO 2.4G RF remote control or wall switch without a ZigBee gateway, follow the pairing instructions provided with your remote/switch. Typically, this involves a short pairing sequence to link the controller and the RF device.

User Tips
- For optimal performance and stability, ensure your ZigBee gateway is within a reasonable range of the controller.
- When switching between CCT and Dimmer modes, observe the indicator light to confirm the active mode.
- If experiencing connectivity issues, try resetting the controller and re-pairing with your gateway or remote.
- Consider using the scene memory function on your remote or app to quickly recall preferred lighting settings.
Troubleshooting
- Controller not responding:
- Check power connections to ensure the controller is receiving power.
- Verify that the LED strip is correctly wired to the controller.
- If using a ZigBee gateway, ensure the gateway is powered on and connected to your network.
- Try resetting the controller by long-pressing the "Reset" button for more than 5 seconds.
- Cannot pair with ZigBee gateway:
- Ensure your gateway is in pairing mode.
- Make sure the controller is within range of the gateway.
- Reset the controller and attempt pairing again.
- Check for any firmware updates for your gateway or controller.
- Remote control not working:
