SONOFF MINI Extreme (Sonoff MINIR4) Wi-Fi smart switch (relay module)

Sonoff"s tiny little Sonoff Mini Extreme (MINIR4) module is one of the smallest Wi-Fi relays on the market, so it will fit into even the smallest wall box.

It may be connected to eWeLink Cloud or to Sonoff iHost hub locally through Wi-Fi protocol, but it also supports eWeLink-Remote (Bluetooth) protocol for local remote control, just as Mini R3 version.

Also, just as Mini R2 version, it has switch input for a wired wall switch, so it's a perfect product to add smart control for a wired switch, and also to add support for additional wireless switches.

Details

Sonoff's new MINIR4 is an extreme mini WiFi smart switch equipped with ESP32 chip, that turns traditional switches into smart switches. You may use it to remote control and automate lights and electronic devices, and thanks to its tiny size (only 33 x 40 mm), it fits in various mounting boxes, including the smallest EU-type/86 type/120 type mounting boxes.

Sonoff MINI R4, also called as Sonoff Mini Extreme, supports external switch control and easily connects to the momentary switch, door exit switch, SPDT switch, latching switch, and even dry contact sensors, just as previous version Sonoff Mini R2.

As a new feature, MINI R4 also has "detach relay" mode, which means the states of external switches and relay are separated, so operating the external switch button won't affect the relay state. Even then, you may use the external switch to trigger a smart scene and operate another device, group of devices or automation. 

As Mini R4 has embedded ESP32 chip, the device comes with support for Bluetooth. The pairing of the device to eWeLink is also processed by Bluetooth-based pairing with the phone, and MINIR4 also features a gateway / hub function of “eWeLink-Remote“, a Sonoff proprietary Bluetooth protocol for local remote control. Sonoff offers R5 wireless switch and S-MATE module (to be installed into a wall box behind a traditional switch) as separately sold products, which can control MINI R4 locally through "eWeLink-Remote" signal, or even can trigger other smart devices with a smart scene.

Just as all other eWeLink relay modules, it supports scedules ON/OFF, power-on-state (ON / OFF / LAST STATUS), smart scenes (automations) and inching (AUTO OFF and AUTO ON) features. Also, to protect the electric network from overload, a power-on delay can be set for after power outage for devices.  

The new Sonoff Mini Extreme R4 module is 40% smaller than MINI R2 and 60% smaller than Mini R3 product version.

Sonoff R4 Extreme supports voice control from Google Assistant (Google Home) and Amazon Alexa voice assistants. 

Sonoff R4 Wi-Fi relay is compatible with Home Assistant, eWeLink Web UI (needs eWeLink Advanced subscription) and IFTTT (needs eWeLink Advanced subscription).
