- LED strip not displaying correct colors/brightness:
- Ensure the LED strip type (RGBCCT) matches the controller's capabilities. Check the wiring of each color channel (R, G, B, C, T, V+) to ensure they are correctly connected.
- Voice control not working:
- Confirm that the controller is successfully paired with your smart home hub and that the hub is online. Ensure the controller and hub are on the same network. Check the device name in your app for accurate voice commands.
User Tips
- For optimal performance and security, always keep your smart home hub's firmware and your smart home app updated to the latest versions.
