5.5 Post-installation
Once wiring is complete and the module is securely placed within the wall box, install the switch panel back into place. Then, restore power at the main circuit breaker.
6. Setup and Pairing
To enable smart control, the ZBMINI-L2 needs to be paired with a compatible Zigbee hub and managed through an application like eWeLink.
- Download the eWeLink App: If you haven't already, download the eWeLink app from your smartphone's app store.
- Wire and Power On: Ensure the ZBMINI-L2 is correctly wired and the power supply is restored.
- Open eWeLink App and Add Device:
- Open the eWeLink App.
- Navigate to your Zigbee gateway (hub) interface.
- Tap the "Add" icon to initiate the device search.
- The app will search for nearby Zigbee devices. Once found, add the ZBMINI-L2 to your gateway.
Important: When the device is in pairing mode, it will remain off and cannot be controlled by its physical button or external switch. If you are using a third-party app or hub, please refer to its specific pairing instructions.
7. Operation
Once successfully installed and paired, you can control your ZBMINI-L2 in several ways:
- App Control: Use the eWeLink app (or your chosen third-party app) to remotely turn the connected device on or off, set schedules, and configure timers.
- Voice Control: Integrate with voice assistants like Amazon Alexa, Google Home, and Alice for hands-free control. Simply use commands such as "Alexa, turn on the living room light" or "Hey Google, turn off the bedroom lamp."
- External Switch Control: Continue to use your existing physical wall switch to control the connected light or device.
- Two-way Control: The ZBMINI-L2 supports two-way control, perfect for staircase lighting or other scenarios where you need to control a light from multiple locations.
- Scene Linkage: Create smart scenes within your app to automate actions. For example, turn on lights when a motion sensor is triggered, or adjust lighting based on the time of day.
- Smart Timer: Utilize countdown, scheduled, or loop timers to automate your devices according to your daily routine.
8. Advanced Features
The ZBMINI-L2 offers several advanced functionalities for a more integrated smart home experience:
- eWeLink Web Control: Manage your devices from a web browser.
- eWeLink Cast: Display and control your devices on compatible smart displays.

9. Maintenance
- Cleaning: Use a dry, soft cloth to clean the device. Do not use harsh chemicals or abrasive cleaners.
- Firmware Updates: Regularly check for firmware updates through the eWeLink app or your chosen Zigbee hub's interface to ensure optimal performance and access to new features.
- Environmental Conditions: Ensure the device is operated within its specified temperature and humidity ranges to prolong its lifespan.
10. Troubleshooting
- Device not pairing:
- Ensure the main power is on and the device is correctly wired.
- Place the ZBMINI-L2 close to your Zigbee hub during the pairing process.
- Verify that your Zigbee hub is compatible with Zigbee 3.0 devices.
- Try resetting the device (refer to the eWeLink app for specific reset instructions if needed) and re-attempt pairing.
- Connected light flickering or not turning on:
- Confirm that the connected light's power consumption is greater than 3W.
- Ensure the load is not an inductive type (e.g., a fan), as the ZBMINI-L2 does not support these.
- Check all wiring connections for looseness or errors.
- No response from external switch:
- Verify that the external switch is correctly wired to the S1 and S2 terminals.
- Check the settings in your eWeLink app to ensure the correct external switch type (rocker or push-button) is selected.
- Voice control not working:
- Ensure the ZBMINI-L2 is successfully paired and online in your eWeLink app.
- Check that your eWeLink account is correctly linked to your voice assistant (Amazon Alexa, Google Home).
- Verify your voice commands are clear and match the device name configured in the app.
11. User Tips
- Zigbee Network Stability: For optimal performance and reliable communication, ensure your Zigbee hub is centrally located within your home. If the switch is far from the hub, consider adding a Zigbee signal repeater (like a smart plug or another always-on Zigbee device) to strengthen the mesh network.
- Firmware Updates: Regularly check for firmware updates through the eWeLink app or your Home Assistant integration. Updates often include bug fixes, performance improvements, and new features.
- Load Compatibility: Remember the 3W minimum load requirement for lights and avoid connecting inductive loads like fans to prevent malfunction.
