The Sonoff E1GS is a dedicated wall switch enclosure designed to house auxiliary modules like the MINIR4, MINIR4M, or ZBMINIR2. It features an ergonomic micro-arc button that provides a tactile feel for manual control, allowing you to integrate smart modules into your home while maintaining a traditional switching experience. Constructed from white, fire-resistant and scratch-resistant polycarbonate, the enclosure measures 86 x 86 x 34 mm. Its ultra-slim profile, with a front panel thickness of 21 mm, makes it suitable for shallow installations. The unit uses a clip-on system for easy mounting and fits into standard 86-type junction boxes as well as European round boxes with a diameter between 60 and 80 mm. This design ensures a clean fit in various wall types without requiring complex wiring for the enclosure itself, operating reliably in temperatures from -10°C to +40°C.
