The Sonoff MINI-2GS, also known as the Mini Duo, is a compact 2-gang smart switch designed to be installed discreetly behind your existing wall switches. It allows you to control two independent lighting circuits or appliances using a single device, supporting a maximum total load of 16A and up to 10A per individual channel. Because it utilizes Matter over Wi-Fi, you can easily integrate it into your preferred ecosystem, whether you use Apple Home, Google Home, or Amazon Alexa. This device operates on a voltage range of 110-240V and requires a neutral wire for installation. A practical addition is the Detach Relay mode, which ensures that your external physical switch and the relay state operate independently, preventing the physical toggle from accidentally overriding your smart settings. To keep your home safe, the unit includes built-in overheat and surge protection. Its small 60mm diameter makes it easy to fit into standard electrical boxes, giving you the convenience of mobile app and voice control without changing the look of your interior switches.
