6. Maintenance
6.1 General Care
To ensure the longevity and optimal performance of your LED strip lights, follow these general care guidelines:
- Avoid exposing the strip to excessive heat or direct sunlight for prolonged periods.
- Do not submerge the strip in water or expose it to high humidity, as it is not water resistant.
- Handle the strip gently to avoid damaging the LED components or the adhesive backing.
6.2 Cleaning
If cleaning is necessary, ensure the LED strip is unplugged from its power source. Gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the strip's material.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power, loose connection, faulty USB port. | Ensure the USB controller is securely plugged into a working 5V USB power source. Try a different USB port or power adapter. |
| Cannot connect to Tuya App / Lights not recognized. | No Zigbee hub, incorrect pairing mode, poor signal, app issues. |
|
| Voice control not working. | Not linked to Alexa/Google Home, incorrect commands, network issues. |
|
| Lights flicker or dim unexpectedly. | Insufficient power, loose connection, faulty strip section. | Ensure the power source provides stable 5V. Check all connections. If only a section flickers, it might indicate damage to that part of the strip. |
