The SONOFF MINI DUO 2-Gang Matter Over Wi-Fi Smart Switch (Model: MINI-2GS) is a compact, dual-channel smart switch designed for seamless integration into modern smart home ecosystems. Part of the MINI Extreme series, it leverages the Matter protocol to ensure cross-platform compatibility with major platforms like Apple Home, Google Home, Amazon Alexa, and Home Assistant, allowing users to control it effortlessly via apps, voice commands, or automated scenes regardless of their preferred ecosystem. This switch supports up to 16A total load across two independent channels (10A per gang for resistive loads), making it ideal for managing dual lighting setups, fans, or other compatible appliances in residential spaces.

Its ultra-compact design measures just 39 x 39 x 18 mm, fitting snugly into standard wall-mounted junction boxes, including the European 60-type, with a minimum mounting box depth of 60 mm required for installation. This enables easy retrofitting behind existing wall switches without major renovations. The device operates on 110-240V~ 50/60Hz AC power and connects via 2.4GHz Wi-Fi, ensuring reliable wireless control. Key innovations include the “Detach Relay” mode, which decouples the physical wall switch from the smart relay state—allowing the switch to act as a trigger for lighting scenes (e.g., for smart bulbs) without toggling the connected load on/off. This is particularly useful for preserving bulb lifespan in smart lighting applications.

Safety is prioritized with built-in protections against overheating, surges, and overloads, alongside flame-retardant materials for long-term reliability. Power-on behavior is customizable: it can remember the last state, default to ON, or stay OFF after a power outage, providing flexibility and peace of mind. Voice integration is robust, supporting commands through Amazon Alexa, Google Assistant, and Apple Siri Shortcuts for hands-free operation. Automation capabilities shine through the eWeLink app (or compatible Matter apps), where users can set schedules, timers, and multi-device scenes—like activating lights at sunset or shutting off appliances upon leaving home.
