7. Maintenance

- Storage: If storing the strip for an extended period, ensure it is disconnected from power and stored in a cool, dry place away from direct sunlight.
- Avoid Bending Sharply: While flexible, avoid bending the strip at sharp angles, especially near the LEDs or connection points, as this can damage the internal wiring.

- Wi-Fi connection issues: Confirm your Wi-Fi network is 2.4GHz (5GHz is not supported). Check your Wi-Fi password and signal strength. Restart your router and the LED strip.
- Voice control not working: Verify that your eWeLink account is correctly linked to Alexa, Google Assistant, or SmartThings. Ensure the voice assistant device is online and has a stable internet connection.
