4. Setup Instructions
Follow these steps to set up your LiebeWH ESP8266 Channel Relay Module:
- Power Connection: Connect a stable 5V DC power supply to the module's power input terminals. Ensure correct polarity.
- Load Connection: Connect the devices you wish to control to the relay output terminals. Each relay supports up to 10A at 250V AC or 30V DC. Refer to the module's silkscreen for Normally Open (NO) and Common (COM) connections.
- Mobile App Installation: Download and install the compatible mobile application on your smartphone. The module uses SmartConfig technology for network setup.
- Network Configuration (SmartConfig):
- Open the mobile application.
- Follow the in-app instructions to initiate the SmartConfig process. This typically involves entering your Wi-Fi network name (SSID) and password.
- The ESP-01 module on the relay board will connect to your Wi-Fi network. The status indicator LED on the module will change to confirm a successful connection.
- Device Pairing: Once connected to the network, the module should appear in your mobile application. You can then name and configure the relay channels as needed.

- Advanced Features: Depending on the app, you may have access to scheduling, timer functions, or integration with other smart home systems.
6. Maintenance
To ensure the longevity and optimal performance of your relay module, follow these maintenance guidelines:
- Keep Clean and Dry: Regularly clean the module with a soft, dry cloth. Avoid exposure to moisture, dust, and corrosive substances.
- Environmental Conditions: Operate the module within its specified temperature and humidity ranges. Avoid extreme heat or cold.
- Inspect Connections: Periodically check all wiring connections to ensure they are secure and free from damage. Loose connections can lead to intermittent operation or electrical hazards.
- Firmware Updates: If available, keep the module's firmware updated through the mobile application to benefit from new features and bug fixes.
7. Troubleshooting
If you encounter issues with your LiebeWH ESP8266 Channel Relay Module, refer to the following troubleshooting tips:
- Module Not Powering On:
- Verify the 5V DC power supply is correctly connected and functioning.
- Check for correct polarity of the power connection.
- Cannot Connect to Wi-Fi:
- Ensure your Wi-Fi network (2.4GHz only) is active and the password is correct.
- Place the module closer to your Wi-Fi router to improve signal strength.
- Restart the module and try the SmartConfig process again.
- Relay Not Switching:
- Check the load connections to the relay terminals.
- Ensure the module is powered and connected to Wi-Fi.
- Verify the command is being sent from the mobile app and the module's status indicator responds.
- Confirm the connected load does not exceed the relay's maximum current rating (10A).
- App Not Detecting Module:
- Ensure your smartphone is connected to the same Wi-Fi network as the module.
- Restart the mobile application.
- If the issue persists, try resetting the module (if a reset button is available) and re-configuring the network.
