The Sonoff MINIR4M-E is a smart wall switch designed to integrate your lighting and electrical circuits into a modern smart home ecosystem. By utilizing the Matter protocol over 2.4GHz Wi-Fi, it allows you to control your devices through the eWeLink app, Google Home, or Amazon Alexa, ensuring broad compatibility across different platforms. This device supports a resistive load of up to 10A and operates within a voltage range of 100-240V, requiring a neutral wire for its live-neutral wiring configuration. Constructed from white PC material, the switch features a compact design measuring 86 x 86 x 34 mm and weighing 84 g, which helps it fit into standard indoor installations. A blue LED indicator provides clear visual feedback on the pairing and online status of the unit. For those who want more flexibility, the device includes a detach relay mode, alongside capabilities for setting smart schedules and scenes to automate your daily routines. Because this unit handles mains electricity and requires specific wire gauges between 16AWG and 14AWG copper conductors, it should be installed by a professional electrician. It is built to operate reliably in temperatures from -10°C to 40°C, making it a dependable choice for homeowners looking to modernize their traditional switches without replacing their existing wall plates.
