Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| LED strip not lighting up. | No power, incorrect wiring, faulty LED strip. | Check power supply connection. Verify input and output wiring polarity. Test LED strip with another power source if possible. |
| Controller not pairing with Matter hub. | Incorrect QR code, hub not Matter-enabled, network issues, controller not in pairing mode. | Ensure you are scanning the correct QR code. Confirm your hub supports Matter. Check Wi-Fi network stability. Reset the controller by holding the "Reset" button for 5 seconds and try pairing again. |
| Lights flicker or behave erratically. | Insufficient power supply, loose connections, incompatible LED strip. | Ensure your power supply meets the voltage and current requirements of your LED strip. Secure all wiring connections. Confirm your LED strip is PWM dimmable and not digital addressable. |
| Voice control not working. | Controller and hub on different networks, voice assistant not configured. | Ensure both the controller and your Matter hub are connected to the same Wi-Fi network. Verify voice assistant settings in your smart home app. |
