5. Setup
5.1 Wiring Instructions
Important: Ensure the main power is OFF before proceeding with any wiring. This device requires a neutral wire (N) for proper operation. The Lout terminals are in parallel; connecting multiple loads will result in simultaneous on/off control.
- Single-Way Switch Circuit: Connect the Live (L) and Neutral (N) wires from your power source to the corresponding L and N inputs on the MINI-ZB1GSP. Connect the Live output (Lout) from the device to your load (e.g., light bulb). Connect the existing wall switch to the S1 terminal and the Live wire (L) or another Live output (Lout) to the other terminal of the switch, depending on the switch type.
- Two-Way Switch Circuit: For two-way control, wire the device as described for a single-way switch. The existing two-way switches will then control the S1 input of the MINI-ZB1GSP.

5.2 Compatible Mounting Box Sizes
The MINI-ZB1GSP is designed to fit into various standard electrical wall boxes. A mounting box depth of at least 60mm is recommended for optimal fit.

5.3 Device Pairing
The SONOFF MINI-ZB1GSP requires a Zigbee hub (coordinator) for full smart home integration. Upon initial power-up, the device automatically enters pairing mode.
- Zigbee Hub Connection: Ensure your Zigbee hub (e.g., SONOFF Zigbee Bridge, SmartThings Hub, Home Assistant with ZHA/Zigbee2MQTT) is in pairing mode. The MINI-ZB1GSP will be detected and added to your network.
- Proximity Mode (Bluetooth): If no stable Zigbee signal is available, you can use proximity mode to connect your phone directly via Bluetooth for basic control and configuration.

6. Operating Instructions
6.1 Smart Control via App and Voice
Once paired with your Zigbee hub, you can control the MINI-ZB1GSP through the eWelink app, Home Assistant, SmartThings, or voice assistants like Alexa.
- App Control: Use the eWelink app (or your preferred smart home app) to turn devices on/off, set schedules, and create smart scenes.
- Voice Control: Integrate with Alexa or other compatible voice assistants to control your connected devices with voice commands.
- Smart Scenes: Create automated routines based on time, sensor triggers, or other smart devices.
