4. Setup and Installation

The MINIR4M offers two primary pairing methods: via the eWeLink App or using the Matter pairing method with compatible smart home apps.

4.1 Wiring Diagram and Physical Installation

Important: Ensure power is disconnected at the circuit breaker before performing any wiring.

1. Identify the Live (L) and Neutral (N) wires in your electrical box.
2. Connect the Live wire from your power source to the "L In" terminal on the MINIR4M.
3. Connect the Neutral wire from your power source to one of the "N" terminals on the MINIR4M.
4. Connect the Neutral wire going to your light fixture or appliance to the other "N" terminal on the MINIR4M.
5. Connect the Live wire going to your light fixture or appliance to the "L Out" terminal on the MINIR4M.
6. For external switch control, connect your physical switch to the "S1" and "S2" terminals. The "S1" terminal is common with "L In".
7. Carefully place the MINIR4M module into the mounting box. Its compact size is designed to fit various standard boxes.

4.2 Device Pairing

After physical installation and restoring power, the device is ready for pairing.

4.2.1 eWeLink App Pairing

1. Download the eWeLink app from your device's app store.
2. Open the eWeLink app and register or log in.
3. Tap the "+" icon to add a new device.
4. Follow the on-screen instructions to put the MINIR4M into pairing mode and complete the setup.

4.2.2 Matter Pairing

For Matter-compatible apps (e.g., Apple Home, Google Home, Alexa, SmartThings):

1. Open your preferred Matter-compatible smart home app.
2. Initiate the "Add Device" or "Add Accessory" process.
3. Scan the Matter QR code located on the MINIR4M device or its packaging.
4. Follow the app's prompts to complete the pairing process.

Image: This diagram illustrates the two methods for setting up the MINIR4M: adding devices through the eWeLink app or using the Matter pairing method by scanning a QR code with a Matter-compatible application.

5. Operating Instructions

5.1 App Control

Once paired, you can control the MINIR4M through the eWeLink app or your chosen Matter-compatible smart home app. The app allows you to:

• Turn the connected device ON/OFF remotely.
• Set schedules and timers for automatic operation.
• Create smart scenes to automate actions based on other smart devices or conditions.
• View device status and operation logs.

5.2 Voice Control

Integrate the MINIR4M with voice assistants like Alexa, Google Home, or Apple HomeKit (via Matter) to control your devices using voice commands. For example, say "Alexa, turn off the light."

5.3 External Switch Control

The MINIR4M allows you to retain the functionality of your traditional wall switch while adding smart capabilities. It supports various switch types:

• Momentary Switch
• Door Exit Switch
• SPDT Switch
• Latching Switch
• Dry Contact Sensors

Image: This diagram illustrates the versatility of the MINIR4M, showing its ability to connect easily to various external switch types, including momentary switches, door exit switches, SPDT switches, and latching switches, allowing for flexible control options.

5.4 Detach Relay Mode

In "Detach Relay Mode," the state of the external physical switch and the internal relay are separated. This means that operating the external switch will not directly affect the relay's state. This mode is useful for maintaining smart control even if the physical switch is in a specific position, or for using the physical switch to trigger smart scenes without directly controlling the load.

Image: This illustration compares normal operation with "Detach Relay" mode. In normal mode, turning off the physical switch makes the smart light offline. In "Detach Relay" mode, the smart light remains controllable via the app even if the external switch is off, as their states are separated.

5.5 Smart Scenes and Automation

Leverage the MINIR4M's capabilities to create smart scenes and automate your home. It can work with motion sensors, door/window sensors, and other smart devices to trigger actions. For example, turn on lights when motion is detected.

Image: This diagram illustrates the "Delay Power-on State" feature, showing how lights in different areas of a house can be configured to turn on with a specified delay (e.g., 1s or 3s delay ON) after power is restored or a trigger occurs, providing additional control and protection.

6. Maintenance

• Firmware Updates: Regularly check for and install firmware updates through the eWeLink app to ensure optimal performance, security, and access to new features.
• Cleaning: If necessary, gently wipe the device with a dry, soft cloth. Do not use liquid cleaners or solvents.
• Connection Check: Periodically ensure all wiring connections are secure.

7. Troubleshooting

• Device Not Responding:
  • Check if the device has power.
  • Verify Wi-Fi connectivity. Ensure the device is within range of your router.
  • Restart the device by cycling its power at the circuit breaker.
  • Check the eWeLink app or Matter-compatible app for device status.
• Cannot Pair Device:
  • Ensure your Wi-Fi network is 2.4GHz. The MINIR4M does not support 5GHz Wi-Fi.
  • Confirm the device is in pairing mode (usually indicated by a blinking LED).
  • Reset the device to factory settings (refer to the eWeLink app for specific instructions) and try pairing again.
  • Ensure your smartphone is connected to the same 2.4GHz Wi-Fi network during pairing.
• External Switch Not Working:
  • Verify the wiring of the external switch to the S1 and S2 terminals.
  • Check the switch mode settings in the eWeLink app.
• Delayed Response:
  • Ensure a strong and stable Wi-Fi signal.
  • Check for network congestion or interference.
  • Update device firmware.
