2. SONOFF ZBMINI L2 Smart Switch Installation
The ZBMINI L2 is a compact smart switch designed for easy integration into existing electrical systems. It is 40% smaller than its predecessor, allowing it to fit into most mounting boxes, including standard EU-type boxes (60mm / 2.36 inches).
- Safety First: Always ensure the power supply is turned OFF at the circuit breaker before performing any wiring or installation.
- Wiring: The ZBMINI L2 does not require a neutral wire for operation. Refer to the wiring diagrams below for connecting with external switches.
- External Switch Type: Before completing installation, ensure you switch to the corresponding external switch type (rocker or push button) if using one.
- Mounting: The tiny size allows it to be easily fitted into the smallest EU-type mounting boxes.

3. SNZB Series Sensor Setup
The SNZB series sensors are battery-powered Zigbee devices that easily pair with the ZBBridge-Pro.
- Pairing: Once the ZBBridge-Pro is set up, open the eWeLink app and follow the instructions to add new Zigbee sub-devices. The ZBBridge-Pro supports "one-tap pairing" for up to 32 sub-devices simultaneously, offering fast pairing speeds.
- Placement: Place sensors in desired locations. For optimal signal, consider the 80m transmit distance in open spaces. Plug-in Zigbee devices (like smart plugs) can act as routers to extend the network range for battery-powered sensors.

Operation
1. eWeLink App Control
The eWeLink app is the central control hub for all your SONOFF smart devices. It allows you to manage both Wi-Fi and Zigbee devices from a single interface.
- Device Management: Turn devices on/off, view status, and configure settings.
- Scene Linkage: Create custom scenes where multiple devices act together based on triggers (e.g., turn on lights when a door opens).
- Smart Timer: Set schedules, countdowns, or loop timers for your devices.
- Smart Home Security: Customize 3 modes (e.g., Home, Away, Sleep) by setting different arming devices. Easily arm and disarm security modes via the app, wireless button, NFC trigger, or schedule.

3. Automation Examples with SNZB Sensors
- SNZB-01 Wireless Switch: Pair with the Bridge to control connected devices, such as blinds, from any corner of your home.
- SNZB-02 Temperature & Humidity Sensor: Connect to the Bridge to detect real-time temperature and humidity. Use this data to trigger other devices, like turning off a fan if the temperature exceeds 28°C or turning on a humidifier if humidity drops below 60%.
- SNZB-03 Motion Sensor: Use to automatically turn on lights when motion is detected in a room, ensuring you never walk into darkness.
- SNZB-04 Door/Window Sensor: Configure to turn off lights or activate security modes when a door or window is closed, indicating you've left home.
