Installation & Setup
Wiring Diagram
The MINIR4 requires both Live (L) and Neutral (N) wires for operation. Refer to the specific wiring diagram for your desired setup, ensuring all connections are secure and correct.
This image provides visual guidance on how to connect the MINIR4 with different types of external switches, demonstrating its versatile compatibility for various control scenarios.
Device Pairing
- Power on the MINIR4.
- Download and open the eWeLink app on your smartphone (available on iOS and Android app stores).
- Follow the in-app instructions to add the device. The MINIR4 will typically enter pairing mode automatically when first powered on. If not, press and hold the pairing button on the device for approximately 5 seconds until the LED indicator flashes rapidly.
- Ensure your Wi-Fi network is 2.4GHz, as the MINIR4 does not support 5GHz networks.
Detach Relay Mode
The "Detach Relay" mode is a unique feature that separates the states of the external switch and the internal relay. This means operating the physical switch will not affect the relay's state, allowing for more flexible automation scenarios where the physical switch acts as a trigger rather than a direct controller. This feature can be configured within the eWeLink app settings for the MINIR4.
Operation
Manual Control
Once installed, the connected light or appliance can still be controlled manually via the physical wall switch, providing traditional control alongside smart functionality.
App Control (eWeLink)
Use the eWeLink app to remotely turn the device on/off from anywhere, set schedules, countdown timers, and create smart scenes based on various conditions (e.g., time of day, device status).
Voice Control
The MINIR4 is compatible with popular voice assistants such as Amazon Alexa and Google Home Assistant. Link your eWeLink account to your preferred voice assistant app to enable convenient voice commands for controlling your connected devices.
eWeLink-Remote Control
Pair the MINIR4 with eWeLink-Remote sub-devices like SONOFF R5 or S-MATE. These sub-devices can then act as remote controllers to control the MINIR4 locally through the eWeLink-Remote signal, offering additional control options without relying solely on Wi-Fi.
This image illustrates the various ways to control the MINIR4, including through eWeLink-Remote sub-devices, setting timers, and using voice commands with smart assistants.
Compatibility & Integration
The SONOFF MINIR4 offers broad compatibility for seamless integration into various smart home ecosystems, enhancing your automation possibilities.
- Voice Assistants: Fully compatible with Amazon Alexa and Google Home Assistant for convenient voice control.
- Smart Home Platforms: Supports integration with Home Assistant, allowing for advanced customization and control within your existing smart home setup.
- Automation Services: Compatible with IFTTT (If This Then That) for creating complex automation routines and connecting with other smart devices and services.
- Web Control: Access and control your devices via eWeLink Web, providing a convenient web-based interface for managing your smart home (requires eWeLink Advanced Plan).
This image demonstrates the MINIR4's extensive compatibility, allowing users to integrate it with popular smart home platforms like Home Assistant, eWeLink Web, and IFTTT for expanded control and automation possibilities.

Maintenance
- Keep the device clean and dry. Avoid exposing it to dust, dirt, or moisture.
- Do not attempt to disassemble or repair the device yourself. Unauthorized modifications can void the warranty and pose safety risks. Contact customer support for assistance.
- Regularly check for firmware updates via the eWeLink app to ensure optimal performance, security, and access to new features.
Troubleshooting
- Device not pairing:
- Ensure your Wi-Fi network is 2.4GHz. Check if the device is in pairing mode (LED indicator flashing rapidly). Move the device closer to your Wi-Fi router to improve signal strength. Temporarily disable 5GHz on your router if you have a combined network.
- Device offline in app:
- Check your Wi-Fi connection and ensure your router is functioning correctly. Restart the MINIR4 by cycling its power. Ensure the eWeLink app is updated to the latest version. If the issue persists, try re-pairing the device.
- External switch not responding:
- Verify all wiring connections are secure and correct according to the installation diagram. Check if "Detach Relay Mode" is enabled in the app, as this separates physical switch control from the relay state. If enabled, the physical switch acts as a trigger, not a direct on/off.
- Device not responding to voice commands:
- Ensure your eWeLink account is correctly linked to your Amazon Alexa or Google Home account. Check your internet connection. Verify the device name in the eWeLink app matches the name used in your voice commands (e.g., "Living Room Light").
