The SONOFF MINIR4 Extreme Wi-Fi Smart Switch provides a mini size module that offers control from an external switch or sensor, as well as via eWeLink, Alexa and Google
The MINIR4 is an extremely compact WiFi smart switch equipped with a ESP32 chip that turns traditional switches into smart switches, automating lights and electronic devices. The tiny size fits in various mounting boxes, including the smaller EU-type/86 type/120 type mounting boxes. The MINIR4 supports external switch control and easily connects to the momentary switch, door exit switch, SPDT switch, latching switch, and even dry contact sensors.
The MINIR4 has a “detached relay” mode, meaning that the states of external switch and relay are separated, so operating the external switch button won’t affect the ability to control the switch via the app and vice versa. Therefor when you turn off the light, your smart light won’t be offline, and you will still be able to use the App to control the lights.
The MINIR4 also has the gateway function of “eWeLink-Remote“. After pairing with the MINIR4, the MINIR4 can be controlled locally by S-MATE through the “eWeLink-Remote” signal and trigger other smart devices via a smart scene.
