5. Setup
5.1 Power Connection
The controller supports flexible power input options:
- DC 5-24V Input: Connect your main power supply to the DC 5-24V input terminals.
- USB-C 5V/5A Power Supply: For 5V applications, you can use a USB-C power adapter (max 5A) to power the controller directly.
Ensure the power supply voltage matches the requirements of your LED strip.


5.2 Wiring LED Strips
The controller features quick-connect terminals for easy wiring. The default output for data is GPIO16. GPIO2 can be configured via the app for additional data output.
- V: Connect to VCC (Positive power for LED strip).
- D: Connect to DATA line of the LED strip.
- G: Connect to GND (Ground for LED strip).
Wiring Steps:
- Open the connector upwards.
- Insert the stripped wire into the terminal.
- Press down the connector to secure the wire.


5.3 App Download
The WLED app is used to control the LED controller.
- iOS: Search for "WLED" or "WLED Native" in the App Store.
- Android: Download from the official GitHub website: github.com/Aircooooke/WLED-App/releases

5.4 Initial WiFi Setup
Follow these steps to connect your controller to your WiFi network:
- Power on the WLED controller.
- Open the phone settings and connect to the WiFi hotspot named "WLED-AP" (password: "wled1234").
- Open a web browser and navigate to 4.3.2.1. Click on "WIFI SETTINGS".
- Select your 2.4GHz WiFi network (5GHz networks are not supported) and enter the password.
- Scroll down and click "Save & Connect".
- The controller will attempt to connect to your home WiFi.
- Once connected, the WLED app will automatically discover the controller.
- Enter the WLED page for configuration.

6. Operating Instructions
6.1 Button Functions
The controller features three buttons: Reset, Opt, and Push.
- Reset Button: Pressing this button will temporarily power off the controller, making it unusable. Releasing the button will power the module back on. This is useful for powering the controller on and off when inconvenient.
- Opt Button:
- Short press: Power on/off.
- Long press (1 second): Adjust color.
- Long press (more than 10 seconds): Resets the WLED device to factory settings and activates the WLED-AP hotspot. Do not use unless necessary or if factory settings have been restored.
- Push Button (GPIO33): This button can be connected to an external push switch for additional control.


6.2 WLED App Control
The WLED app provides comprehensive control over your LED strips:
- Color Control: Select from 16 million+ colors using the color picker.
- Effects Library: Choose from over 100 built-in professional-grade lighting effects.
- Segmented Lighting: Program different colors and effects for specific segments of your LED strip.
- Presets and Scenes: Save and recall your favorite lighting configurations.
- User Interface: Customize the app interface and settings.
- Sync Interfaces: Manage synchronization with other WLED devices.
- Time & Macros: Schedule lighting changes and create custom macros.

6.3 Remote Control (Optional)
The controller supports WLED remote control for convenient operation. Please note that the remote control is sold separately and is not included with the controller.

6.4 Voice Assistant Integration (Alexa)
The DOM-WLE-A controller can be integrated with Amazon Alexa for voice control:
- Go to the control page of the WLED controller in the app, click on the "Config" button in the top right corner.
- Navigate to "Sync Interfaces".
- Scroll up to find "Alexa Voice Assistant", check the box next to "Emulate Alexa device", and then save.
- After successfully saving, power cycle the WLED controller once by turning it off and on.
- Open the Amazon Alexa app, click on the "Devices" page at the top right corner, then the "+" Sign, and then click "Add Device".
- Select "Other" or "Smart Home" device type.
- Follow the on-screen instructions to discover new devices.

7. Maintenance
- Keep the controller clean and free from dust. Use a dry, soft cloth for cleaning.
- Avoid exposing the device to direct sunlight or high humidity.
- Ensure proper ventilation around the controller to prevent overheating.
- Regularly check all wiring connections for tightness and integrity.
8. Troubleshooting
- LEDs do not light up after reset: Ensure GPIO12 configuration is complete. If abnormal, reconfigure and reboot the controller. If normal, inspect the power supply circuit and LED strip connections.
- Controller not connecting to WiFi: Double-check your WiFi password and ensure you are connecting to a 2.4GHz network. Power cycle the controller and try the setup process again.
- Incorrect colors or effects: Verify the LED strip type is correctly configured in the WLED app settings. Check wiring for data and ground connections.
- Controller unresponsive: Try a short press on the Opt button to power cycle. If still unresponsive, perform a long press (over 10 seconds) on the Opt button to reset to factory settings (note: this will erase all custom configurations).
- Flickering LEDs: Ensure your power supply is adequate for the length and density of your LED strip. If the number of ICs is too large for the controller's rated current, increase the power supply capacity.
9. User Tips
- Power Supply Matching: Always ensure your power supply is sufficient for your LED strip's total power consumption. If the number of ICs (integrated circuits) on your strip is high, consider a higher amperage power supply to prevent flickering or dimming.
- USB-C Power Limit: When using the USB-C interface, the input voltage must be 5V and the maximum current 5A. Do not exceed these limits to avoid damaging the controller.
- Default Data Pin: For initial setup, always use the GPIO16 port for your LED strip's data line. The GPIO2 port can be enabled and configured later through the WLED application if needed for a second data output.
- Firmware Updates: As the WLED project is open-source, regularly check for firmware updates within the app or WLED community forums to access new features and improvements.
