The Sonoff ZBMINIL2 is a compact Zigbee 3.0 smart switch designed to bring wireless control to your existing lighting without requiring a neutral wire. This makes it an ideal choice for upgrading older homes where the electrical wiring might otherwise limit smart home installations. It supports a wide input voltage range from 100 to 240 V and can handle a maximum current of 6 A, provided the connected light has a minimum load of 3 W. Measuring just 39.5 x 32 x 18.4 mm, the device is small enough to fit inside standard EU, 86, or 120 wall boxes, allowing you to keep your current physical switches while adding smart functionality. The housing is made from white flame-retardant PC material for added safety, and the internal circuitry includes both overheating and overload protection to keep your electrical system secure. You can manage your devices through the eWeLink app or use voice commands via Amazon Alexa and Google Assistant for a more hands-free experience.
