SONOFF MINI R4 Smart Switch is an ultra-compact WiFi-enabled smart module designed to transform traditional switches into intelligent control systems. Operating within AC 100–240V and supporting loads up to 2400W, this Extreme version is smaller and more flexible, making installation easier inside standard recessed wall boxes. With the eWeLink mobile app, users can control connected devices remotely, set schedules, and automate daily routines. Moreover, the MINI R4 supports voice commands through Amazon Alexa and Google Assistant for hands-free control.
One of its standout features is the Detach Relay Mode, which separates the external switch state from the relay state. Therefore, smart bulbs remain online and app-controllable even when the physical switch is toggled. Additionally, it supports multiple switch types including momentary, latching, SPDT, and dry contact sensors. For extended local control, it works with SONOFF R5 and S-MATE through eWeLink-Remote communication. Featured By RoboticsBD.
