The SONOFF MINIR4 MINI Extreme is an ultra-compact smart switch engineered to upgrade existing electrical setups without compromising on space. Designed with a miniature form factor, it easily fits into a wide variety of mounting boxes, including the smallest European standard enclosures.
Powered by a high-performance ESP32 chip, the MINIR4 provides faster response times, robust wireless connectivity, and enhanced processing capability for dependable smart home automation. It offers versatile external switch compatibility, supporting momentary, door exit, SPDT, and latching switches, as well as dry contact sensors.
Featuring an innovative “detach relay” mode, the physical switch and internal relay can operate independently—allowing manual button presses without altering the relay state. In addition, the MINIR4 functions as an eWeLink-Remote gateway, enabling seamless pairing and local control with compatible sub-devices such as the R5 and S-MATE.
