The SONOFF MINI DUO (MINI-2GS) is an ultra-compact, Matter-certified dual-channel smart switch designed to transform traditional 2-gang switch plates into automated powerhouses without taking up excess space. Operating over a stable 2.4GHz Wi-Fi connection, it features native Matter compatibility to integrate directly into Apple Home, Google Home, Amazon Alexa, and Home Assistant without proprietary bridges or cloud lock-ins. This versatile module enables completely independent control of two separate lights or light-and-fan combinations, delivering a total load capacity of up to 16A. Built for safety with flame-retardant PC V-0 housing, overload protections, and an intelligent "Detach Relay" mode, it is the ultimate, future-proof solution for multi-load smart home retrofitting.
Overview:
The SONOFF MINI DUO 2-Gang Matter Over WiFi Smart Switch (MINI-2GS) represents a major breakthrough in local, cross-platform home automation. Powered by the highly efficient Espressif ESP32-C3 RISC-V chipset, it processes automated tasks completely locally for rapid, split-second response times and enhanced user privacy. Measuring at an ultra-miniature size, it slips comfortably behind existing mechanical switches in standard 60-type wall boxes without requiring extensive modifications. The MINI-2GS natively supports multi-admin platform synchronization, allowing different household members to manage the exact same light using their preferred devices across Apple, Android, or voice assistants. With advanced features including configurable power-on memory behaviors for stable recovery from load shedding outages, full 2-way toggle switch compatibility, and robust hardware protections, it is the perfect zero-hassle upgrade for comprehensive multi-load management.
Features:
- Universal Native Matter Compliance: Connects directly to Apple Home, Google Home, Amazon Alexa, and SmartThings natively via Wi-Fi with no external hubs required.
- Dual Independent Loads Controlled: Manage two lights or a light + fan combo completely independently from a single, space-saving hidden module.
- Heavy Duty 16A Maximum Capacity: Handles resistive electrical loads up to 10A per individual gang, with a robust combined maximum total of 16A.
- Ultra-Compact Profile Architecture: Tiny 45 × 39.4 × 16.8 mm footprint slots easily inside crowded, standard-depth electrical wall boxes.
- Innovative Detach Relay Mode: Disconnects physical switch behavior from internal relay output, enabling you to use wall toggles as software scene triggers while keeping smart bulbs online.
- Hybrid Mechanical Switch Support: Auto-detects and works perfectly with standard mechanical rocker/toggle switches or momentary push-button setups.
- Smart Post-Load Shedding Recovery: Configure individual channels to default to ON, OFF, or remember their Last State to protect electronics when grid power returns.
- Industrial Hardware Protection Matrix: Features built-in overheat protection, surge safeguards, and overload tracking enclosed in fire-retardant PC V-0 housing.

Unified Multi-Brand Integration Natively with Matter
Break down ecosystem barriers for good. Natively supporting the universal Matter protocol over Wi-Fi, the MINI-2GS communicates directly with other Matter-certified smart home components across completely different brands. This native local interaction eliminates ecosystem lock-in, creating a seamless, unified, and collaborative smart home environment.
*Note: True local integration with Apple, Google, or Alexa smart apps via Matter requires a local platform hub (such as an Apple HomePod, Google Nest Hub, or Amazon Echo).
Simultaneous Local Control Across All Major Ecosystems
— Bring absolute flexibility to multi-device households. Thanks to Matter's robust Multi-Admin feature, the MINI DUO can be connected to multiple smart ecosystems simultaneously. While you track your lighting on an Apple iPhone using Siri, other family members can interact with the exact same switch through Android devices or Amazon Alexa voice prompts.
Double the Output, Half the Space: 2-Gang Control Module
- Optimize your switch box density and maximize efficiency. The MINI-2GS delivers two completely independent control channels out of a single hidden module, letting you manage two distinct lighting circuits or a dedicated light + extraction fan combo simultaneously from a single physical wall switch box point.
Ultra-Miniature Dimension Scaling for Crowded Boxes
Big smart capabilities packed into an impossibly small package. Shrunk down to an ultra-compact size as part of the MINI Extreme series, this tiny module slides smoothly behind your original mechanical switch wall plates. It requires zero cosmetic wall adjustments, letting you keep your decorative fixtures pristine while retrofitting advanced tech.
Keep Smart Lights Online with Detach Relay Mode
Say goodbye to smart bulbs becoming completely unresponsive in your app when someone flips the wall switch. When you turn on Detach Relay mode, the physical wall toggle is digitally separated from the electrical relay output. The wall switch functions as a custom smart scene trigger, while continuous mains power flows uninterrupted to your smart lights.
Local execution, Faster Triggers, and Full Cloud Independence
Experience split-second response speeds with local home automation logic. Because Matter triggers pass directly over your local Wi-Fi router network, data packets travel locally from sensors to the switch instead of making lengthy round-trips to external internet cloud servers. This guarantees immediate execution speeds and ensures your automated routines continue working perfectly even if your external internet line goes completely offline.
Smart Schedules and Rich Automation Scenes
Let your home seamlessly adjust itself to your daily routines. Create precise, automated lighting schedules, recurring countdown timers, or sophisticated smart group triggers via the eWeLink app or your chosen Matter dashboard to coordinate your household lighting autonomously around sunrise, sunset, or motion activity.
Comprehensive Multi-Level Structural Safety Systems
Rest easy knowing your electrical setup is backed by hardware-level protections. Built entirely from premium, flame-retardant PC V-0 housing materials, the device features strict internal overheat sensors, overload protection cutoffs, and electrical surge safeguards to ensure safe, cool, and reliable operation inside your walls 24/7.
