The Sonoff MINI-ZB2GS-L, also known as the MINI DUO-L, is a compact 2-gang smart switch designed to bring intelligent control to two separate lighting circuits. Because it requires no neutral wire, you can easily integrate it into older homes where such wiring is missing, avoiding the need for costly electrical renovations. It operates on the Zigbee 3.0 protocol, ensuring a stable and energy-efficient connection to your smart home hub. This device supports an input voltage of 100-240V AC and can handle a maximum load of 8A per channel, with a total capacity of 12A. For those using LED lighting, it supports up to 300W per channel at 240V, though a minimum load of 3W is necessary for stable operation. The internal EFR32MG22 microcontroller manages these processes within a small, white polycarbonate housing that measures 45 x 39.4 x 16.8 mm and weighs only 33 g. Its small footprint allows it to fit comfortably inside European 60 and other small junction boxes, making it a practical choice for users who want to maintain their existing wall switches while adding remote or automated control. To ensure a safe installation, it is recommended to use 16AWG to 14AWG solid or stranded copper wiring.
