8. Troubleshooting
If you encounter issues with your GLEDOPTO LED Strip Controller, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | No power supply; incorrect voltage; faulty power adapter. | Verify power supply connection. Ensure input voltage is DC 5-24V. Test with a different power adapter if available. |
| LEDs not lighting up or flickering | Incorrect wiring (Data, GND, VCC); loose connections; incompatible LED strip; insufficient power for LED strip. | Double-check wiring according to the diagram (V, D, G). Ensure all quick-connects are secure. Confirm LED strip type is compatible. Use an adequate power supply for the length and type of LED strip. |
| Cannot connect to WLED-AP WiFi | Controller not in AP mode; WiFi interference. | Long press the 'Opt' button for 10 seconds to reset and activate WLED-AP hotspot. Try connecting from a different device or location to rule out interference. |
| Controller not appearing in WLED app after WiFi setup | Incorrect WiFi credentials; controller failed to connect to home network; network firewall. | Ensure correct SSID and password were entered during setup. Restart the controller. Check router settings for any client isolation or firewall rules blocking communication. Ensure your phone is on the same WiFi network as the controller. |
| Microphone function not working | Microphone not configured; ambient noise too low. | Ensure microphone settings are correctly configured within the WLED app (e.g., input type, gain). Increase ambient sound or music volume. |
