The Sonoff ZBMINIR2 is a compact Zigbee 3.0 smart switch designed to bring intelligent control to your existing home lighting without requiring you to replace your current wall switches. This device integrates seamlessly into your electrical system, supporting rocker, SPDT, and momentary switches while requiring a neutral wire for stable operation. With a maximum resistive load of 10A and a power capacity of 2400W, it handles a wide range of household appliances across a voltage span of 100-240V AC. Measuring just 39.5 x 33 x 16.8 mm and weighing 26.7 g, the module is small enough to fit inside most standard junction boxes. Its housing is made from white flame-retardant PC material, ensuring safety during long-term use. Beyond simple switching, the device acts as a Zigbee router, which helps extend your network's reach by supporting up to 64 end devices. For added peace of mind, it includes built-in overload and overheat protection. You can manage your lighting through the eWeLink app or use voice commands via Amazon Alexa and Google Assistant for hands-free control. This makes it a practical choice for anyone looking to automate their home environment while maintaining the tactile feel of traditional switches.
