SONOFF MINI-2GS (MINI DUO) is an ultra-compact, two-output (2-gang) smart switch module with Matter over Wi-Fi support. It fits into a standard junction box and adds smart functions to your existing wall switches: remote on/off, scheduling, group control and scenes. It handles a total load of up to 16 A (up to 10 A/gang for a resistive load), so two separate circuits can be automated from a single, hidden module.

Thanks to Matter support, the MINI-2GS can be easily integrated into multiple smart home ecosystems with unified control and quick pairing. The physical button remains, but the control is expanded: from an app, with voice or automations.

The SONOFF MINI-2GS Matter version does not support the eWeLink-Remote protocol, i.e. it cannot be used together with wireless Sonoff Bluetooth switches and modules.

As usual from Sonoff, the high quality of the device is confirmed not only by the usual CE certification, but also by a test certificate from the German TÜV Rheinland laboratory.

Compatible with Home Assistant, SmartThings, IFTTT and Apple Home.

Main product features

- Two relay outputs: control of two independent circuits from one module (10 A/gang, total 16 A max, resistive load).
- Matter over Wi-Fi: uniform, brand-independent integration and quick pairing with Matter-enabled applications.
- Small size: ultra-compact size (45 × 39.4 × 16.8 mm) for most wall boxes.
- Switch type switching: rocker and push button are supported;
- Scheduling and scenes: timings, Smart Scene, group control, sharing.
- Power-On State: determination of the state after a power failure (On/Off/last state).

Smart home protocols and platform compatibility

- Supported protocol: Matter over Wi-Fi (IEEE 802.11 b/g/n 2.4 GHz).
- Ecosystems: compatible via Matter (e.g. Apple Home, Google Home, Amazon Alexa, SmartThings, the range of functions may vary by platform).
- EWeLink mode: the device can also be registered and controlled with the eWeLink application.
- Local displays: blue LED to indicate pairing/online/offline status.

Smart functions

- Remote control: on/off from mobile app.
- Timings: scheduled connections for daily routines.
- Scenes: Smart Scene-based automation with other tools.
- Sharing: device sharing with family members.
- Group control: simultaneous control of several devices.
