1. Introduction
The SONOFF ZBMINIR2 is a compact ZigBee smart switch designed to integrate traditional lighting into a smart home system. It requires a neutral line for operation and a compatible ZigBee hub for full functionality. This device allows for remote control, voice control, and automation of connected lights and appliances.
The ZBMINIR2 also functions as a ZigBee router, extending the range and stability of your ZigBee network. Its small size facilitates installation behind existing wall switches.

Step-by-Step Guide:
- Power Off: Turn off the main power supply at your circuit breaker to the light switch you intend to modify. Verify power is off using a voltage tester.
- Remove Existing Switch: Carefully remove the faceplate and unscrew the existing light switch from the wall box. Disconnect the wires from the old switch.
- Wiring the ZBMINIR2:
- Connect the Live (L-in) wire from your electrical supply to the 'L In' terminal on the ZBMINIR2.
- Connect the Neutral (N) wire from your electrical supply to the 'N' terminal on the ZBMINIR2.
- Connect the Load (L-out) wire (going to your light fixture) to the 'L Out' terminal on the ZBMINIR2.
- If using an external switch, connect the two wires from your traditional switch to the 'S1' and 'S2' terminals on the ZBMINIR2.

- Mount the ZBMINIR2: Carefully tuck the wired ZBMINIR2 into the wall box. Ensure wires are not pinched.
- Reinstall Switch Panel: Reattach your original light switch and faceplate to the wall box.
- Power On: Restore power at the circuit breaker. The device will automatically enter pairing mode (green LED indicator will flash slowly).
6. Operating Instructions
6.1 Pairing with a ZigBee Hub
- Ensure your SONOFF ZigBee hub (or compatible ZigBee hub) is powered on and in pairing mode.
- Open the eWeLink app (or your preferred ZigBee hub app).
- In the app, select the option to add a new device or scan for devices.
- The ZBMINIR2 will automatically enter pairing mode when first powered on. If not, long-press the button on the ZBMINIR2 for 5 seconds until the green LED indicator flashes slowly.
- Follow the on-screen instructions in your app to complete the pairing process.
6.2 eWeLink App Control
Once paired, you can control the ZBMINIR2 through the eWeLink app:
- On/Off Control: Tap the device icon in the app to toggle the connected light/appliance on or off.
- Scene & Timer Control: Use the app to set schedules, countdown timers, or create smart scenes that automate actions based on other smart devices or conditions.
- Group Control: Group multiple ZBMINIR2 devices or other smart devices to control them simultaneously with a single command.
6.3 Voice Control
The ZBMINIR2 is compatible with voice assistants like Amazon Alexa and Google Home when connected to a compatible ZigBee hub and linked to your eWeLink account.
- Amazon Alexa: After linking your eWeLink account to Alexa, you can say commands like, "Alexa, turn on the living room lights."
- Google Home: After linking your eWeLink account to Google Home, you can say commands like, "Hey Google, turn off the kitchen light."

6.4 Detach Relay Mode
This mode separates the state of the external switch from the relay, allowing the physical switch to act as a trigger for smart scenes without directly controlling the power to the load. This is useful for maintaining smart bulb functionality even when the physical switch is toggled.
- Enable Detach Relay Mode in the eWeLink app settings for the ZBMINIR2.
- When enabled, the physical switch can be used to trigger smart scenes, while the connected smart bulb remains online and controllable via the app or voice commands.

6.5 ZigBee Router Functionality
The ZBMINIR2 acts as a ZigBee router, extending the signal range of your ZigBee network. This helps to improve the stability and coverage of your smart home devices, especially in larger homes or areas with signal interference.

7. Maintenance
- Cleaning: Use a dry, soft cloth to clean the device. Avoid using harsh chemicals or abrasive cleaners.
- Firmware Updates: Regularly check the eWeLink app for available firmware updates to ensure optimal performance and access to new features.
- Network Stability: Ensure your ZigBee hub is centrally located and that there are enough ZigBee router devices (like the ZBMINIR2) to maintain a strong mesh network.
8. Troubleshooting
- Device Not Responding:
- Check if the device is powered on and the circuit breaker is not tripped.
- Verify the ZigBee hub is online and functioning correctly.
- Ensure the ZBMINIR2 is within range of the ZigBee hub or another router device.
- Try re-pairing the device if connectivity issues persist.
- Green LED Not Flashing During Pairing:
- Ensure the device is powered on.
- Long-press the button on the ZBMINIR2 for 5 seconds to manually enter pairing mode.
- Voice Control Not Working:
- Confirm that your eWeLink account is correctly linked to Alexa or Google Home.
- Check the device name in the eWeLink app and ensure it is recognized by your voice assistant.
- Verify your voice assistant device is online and connected to the internet.
- Smart Bulb Goes Offline (without Detach Relay Mode):
- This is expected behavior if the physical switch cuts power to the smart bulb. Enable Detach Relay Mode in the app to prevent this.
