4. Setup
4.1 Wiring Instructions
Before wiring, ensure the main power supply is turned off at the circuit breaker. Connect the MINIR4M according to the appropriate wiring diagram for your setup (e.g., for a light switch, ensure neutral wire is available).
The device supports connection to momentary switches, door exit switches, SPDT switches, latching switches, and dry contact sensors.
4.2 App Installation
Download the eWeLink App from the App Store (iOS) or Google Play Store (Android). Register an account and log in.
4.3 Pairing Methods
The MINIR4M offers two primary pairing methods:
- eWeLink App Pairing: Follow the in-app instructions to add the device. This typically involves putting the device into pairing mode (refer to the device's LED indicator for status) and searching for it within the eWeLink app.
- Matter Pairing: For Matter-compatible apps (e.g., Alexa app, Apple Home app, Google Home app), you can add the device by scanning the Matter QR code provided with the product. This allows for direct integration into your preferred Matter-enabled smart home platform.

5. Operating Instructions
5.1 Basic Control
Once paired, you can control the connected device (e.g., light) via the eWeLink app, Matter-enabled apps, or the physical button on the MINIR4M.
5.2 Detach Relay Mode
The 'Detach Relay Mode' allows the states of external switches and the internal relay to be separated. This means operating the external switch button will not affect the relay's state. This mode is particularly useful for maintaining smart control even if a traditional wall switch is toggled, ensuring the smart light remains online and controllable via the app.

5.3 App & Voice Control
The MINIR4M supports control through the eWeLink app and voice commands via integrated platforms like Amazon Alexa, Google Home, and Apple Home. This allows for convenient hands-free operation and remote control.

5.4 Scheduling and Smart Scenes
Utilize the eWeLink app to set schedules for automatic ON/OFF operations. Create smart scenes to automate your home based on various triggers, such as motion detection, door/window sensor status, or time of day.

6. Maintenance
The SONOFF MINIR4M requires minimal maintenance. Keep the device clean and free from dust. Do not attempt to disassemble or repair the device yourself, as this will void the warranty and may pose safety risks. For cleaning, use a dry, soft cloth. Avoid using harsh chemicals or abrasive cleaners.
7. Troubleshooting
If you encounter issues with your MINIR4M, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device offline in app | No Wi-Fi connection, weak signal, router issues. | Check Wi-Fi signal strength, restart router, re-pair device if necessary. Ensure device is within Wi-Fi range. |
| Cannot pair device | Incorrect pairing mode, wrong Wi-Fi password, 5GHz Wi-Fi network. | Ensure device is in pairing mode (LED blinking), verify Wi-Fi password, connect to a 2.4GHz Wi-Fi network. |
| Device not responding to commands | Power issue, app glitch, network delay. | Check power supply, restart app, check internet connection. |
| External switch not working | Incorrect wiring, 'Detach Relay Mode' enabled. | Verify wiring connections. If 'Detach Relay Mode' is enabled, the external switch will not directly control the relay state. Adjust settings in the app if needed. |
