5.2 Power Connection
Connect a DC 5-12-24V power supply to the controller's input terminals. Ensure the polarity is correct (V+ to V+, GND to GND). The controller supports a total output current of up to 15A, with a maximum of 10A per channel. Select a power supply appropriate for your LED strip's total power consumption.
6. Operating Instructions
6.1 WLED Application Control
The GLEDOPTO controller integrates seamlessly with the WLED application, allowing for intuitive control via Wi-Fi. No additional gateway is required.
- Download WLED App: Search for "WLED" in your smartphone's app store and install it.
- Connect to Controller's Wi-Fi: Power on the controller. On your smartphone, go to Wi-Fi settings and connect to the Wi-Fi network broadcast by the controller (usually named "WLED-AP" followed by some numbers).
- Configure Network: Open the WLED app. It should detect the controller. Follow the in-app instructions to connect the controller to your home Wi-Fi network.
- Control Lighting: Once connected to your home network, you can use the WLED app to select from over 100 dynamic modes, customize colors, brightness, and create personalized lighting effects.

8. Troubleshooting
If you encounter issues with your GLEDOPTO ESP32 WLED Digital LED Controller, refer to the following common problems and solutions:
- LEDs not lighting up:
- Check power supply connection and ensure correct voltage (DC 5-12-24V) and polarity.
- Verify LED strip wiring (Data, V+, GND) is correct and secure.
- Ensure the LED strip type selected in the WLED app matches your physical strip.
- Confirm the power supply provides sufficient current for your LED strip length.
- Cannot connect to Wi-Fi:
- Ensure the controller is powered on and within range of your Wi-Fi router.
- Try restarting the controller.
- If connecting to the controller's access point (AP mode), ensure your phone is disconnected from other Wi-Fi networks.
- Verify correct Wi-Fi credentials if connecting to your home network.
- Lights are flickering or behaving erratically:
- Check for loose wiring connections.
- Ensure the power supply is stable and adequate for the number of LEDs.
- Consider adding a capacitor across the power lines near the LED strip if flickering persists, especially with long strips.
- Verify the data line is not too long or experiencing interference.
