Sonoff Mini Duo 2-Gang Matter Smart Switch (MINI-2GS)
Add Smart Control to Two Circuits Without Replacing Your Wall Switches
Upgrade your home’s lighting and appliances without changing the look of your existing switches. The Sonoff Mini Duo 2-Gang Matter Smart Switch (MINI-2GS) is an ultra-compact dual-channel Matter over WiFi smart relay that installs discreetly behind compatible wall switches, allowing you to independently control two separate lights, fans, or electrical loads from a single module.
With support for the latest Matter smart home standard, voice assistants, powerful automations, and SONOFF’s innovative Detach Relay Mode, the MINI-2GS is the perfect solution for modernising existing wiring while keeping your home’s original switch plates.
Control Two Devices Independently
Why install two smart relays when one can do the job?
The MINI-2GS features two fully independent relay channels, allowing you to control two separate circuits from one compact device.
Ideal for:
- Two lighting circuits
- Light and ceiling fan combinations
- Outdoor lights
- Bathroom light and extractor fan
- Kitchen lighting
- Staircase lighting
- Two separate appliances
Each channel supports up to 10A, with a combined maximum resistive load of 16A, making it suitable for a wide range of residential smart home applications.
Matter Certified for Universal Smart Home Compatibility
Enjoy seamless integration with all major Matter ecosystems.
The MINI-2GS works with:
- Apple Home & Siri
- Google Home & Google Assistant
- Amazon Alexa
- Samsung SmartThings
- Home Assistant
- eWeLink
- Other Matter-certified platforms
No dedicated smart home hub is required, allowing you to control your devices through your preferred ecosystem while remaining future-proof as your smart home grows.
Detach Relay Mode – Perfect for Smart Bulbs
One of the MINI-2GS’s most powerful features is Detach Relay Mode.
Normally, flipping a wall switch cuts power to the connected device. With Detach Relay Mode enabled, the physical wall switch becomes an independent smart input while the relay state remains unchanged.
This allows you to:
- Keep smart bulbs permanently powered
- Trigger automations without switching power
- Activate scenes with a wall switch
- Create advanced Matter and Home Assistant automations
- Separate manual switch operation from relay control
It’s an ideal solution for homes using colour-changing or smart LED bulbs.
Hidden Installation, Clean Finish
The MINI-2GS installs discreetly behind compatible wall switches, preserving the appearance of your home while adding powerful smart functionality.
Features include:
- Ultra-compact design
- Fits most standard wall boxes (60mm depth recommended)
- No need to replace existing switch plates
- Ideal for renovations and retrofits
- Simple wiring for professional installers and experienced DIY users
Once installed, your home looks exactly the same—but works much smarter.
