The Sonoff MINIR4 Extreme is a compact Wi-Fi smart switch designed to bring intelligent control to your home lighting and appliances. Powered by an ESP32 chipset, this module connects to 2.4 GHz networks and allows you to manage devices remotely or through voice commands using Amazon Alexa and Google Assistant. It supports a wide input voltage range from 100-240 V and can handle a maximum load current of 10 A, though it does require a neutral wire for installation. Measuring just 39.5 x 33 x 16.8 mm, the device is housed in a white, flame-retardant PC shell that fits easily into standard electrical boxes. Its versatility is evident in the wide range of compatible triggers, as it works with latching, momentary, and SPDT switches, as well as door exit switches and dry contact sensors. This means you can keep your existing physical switches while adding the ability to set timers, create custom schedules, and build smart scenarios. To ensure safe operation, the switch includes built-in overheat and overload protection. This makes it a reliable choice for users who want to automate their environment without sacrificing the tactile feel of a traditional wall switch.
