- Installation should be performed by a qualified electrician or in accordance with local electrical codes.
- Do not exceed the maximum load current of 10 Amps.
- Ensure proper insulation and secure wiring connections to prevent short circuits.
- The S1 and S2 terminals are designed for weak current connections only. Do not connect strong current to these terminals.
5. Installation Guide
5.1 Wiring Diagram

Detailed wiring diagram illustrating how to connect the SONOFF MINIR2 smart switch to an electrical circuit, showing connections for Live In (Lin), Neutral In (Nin), Live Out (Lout), Neutral Out (Nout), and external switch terminals S1 and S2.
Follow the diagram carefully to connect the Live (L) and Neutral (N) wires from your power source to the Lin and Nin terminals respectively. Connect your appliance or light fixture to the Lout and Nout terminals. For external switch control, connect your traditional wall switch to the S1 and S2 terminals.
5.2 App Setup (eWeLink App)

This image highlights the scheduling features of the SONOFF MINIR2, including options for setting timers, countdowns, and loop timers to automatically switch devices on or off, optimizing power consumption.
- Download the eWeLink app from the App Store (iOS) or Google Play Store (Android).
- Register a new account or log in if you already have one.
- Power on the SONOFF Mini R2. The Wi-Fi LED indicator will flash rapidly (two short, one long flash) indicating pairing mode. If not, press and hold the pairing button for 5 seconds until it flashes.
- In the eWeLink app, tap the '+' icon at the bottom of the screen to add a device.
- Select 'Quick Pairing' and follow the on-screen instructions to connect the device to your 2.4GHz Wi-Fi network.
- Once connected, you can rename the device and assign it to a room.
6. Operation
6.1 App Control
After successful pairing, you can control the SONOFF Mini R2 directly from the eWeLink app. You can turn the connected device on/off, set schedules, timers, and create smart scenes.
6.2 Voice Control (Amazon Alexa & Google Home)

To enable voice control, link your eWeLink account with Amazon Alexa or Google Home through their respective apps. Once linked, you can use voice commands such as:
- "Alexa, turn on [device name]."
- "Hey Google, turn off [device name]."
6.3 External Switch Control

This image demonstrates the compatibility of the SONOFF MINIR2 with different types of external wall switches, including SPDT switches and NC/NO push-button switches, allowing for traditional manual control.
The Mini R2 supports various external switch types, including SPDT switches and NC/NO push-button switches. This allows you to retain your traditional wall switch functionality while adding smart control.
Pulse Mode

An illustration of the pulse mode functionality, where a falling edge trigger reverses the relay level. This mode is ideal for push-button switches that automatically bounce back, such as those used with door control.
Edge Mode

This diagram explains the edge mode, where both rising and falling edges can trigger a relay state change. It shows how to connect the MINIR2 with SPDT switches to achieve two-way control of a lighting fixture.
6.4 Following Mode

This diagram explains the 'Following mode' feature, where the SONOFF MINIR2 can be connected to various sensors like NC/NO wall switches, radar sensors, pressure sensors, and dry contact sensors, allowing the light state to follow the sensor's input.
In 'Following mode', the device's state can be configured to follow the ON/OFF direction of a connected wall switch or other dry contact sensors (e.g., radar, pressure sensors). This ensures synchronization between the physical switch and the smart module.
7. Maintenance
- Keep the device clean and free from dust. Use a dry cloth for cleaning.
- Regularly check for firmware updates through the eWeLink app to ensure optimal performance and security.
- Avoid exposing the device to extreme temperatures or humidity beyond its specified operating conditions.
8. Troubleshooting
- Device not pairing: Ensure your Wi-Fi network is 2.4GHz. Check if the Wi-Fi indicator is flashing correctly. Try resetting the device by pressing the pairing button for 5 seconds.
- Device offline in app: Check your Wi-Fi signal strength. Ensure your router is working correctly. Restart the device and your router.
- Voice control not working: Verify that your eWeLink account is correctly linked to Amazon Alexa or Google Home. Ensure the device name is recognized by the voice assistant.
- External switch not responding: Check the wiring to the S1 and S2 terminals. Ensure the correct external switch mode (Pulse or Edge) is selected in the eWeLink app if applicable.
- Device not turning on/off: Check the main power supply. Verify the wiring connections (Lin, Nin, Lout, Nout). Ensure the load does not exceed 10 Amps.
