Sonoff’s new MINIR4M is a Matter smart home standard compatible mini Wi-Fi smart switch, that turns traditional switches into smart switches. You may use it to remotely 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 R4M, also called as Sonoff Mini Extreme R4 Matter version, 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 or Mini R4 product version.

As a new feature, MINI R4M 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.

Mini R4M is the Matter compatible product version with support for Bluetooth pairing. It can work with eWeLink app (just as MINIR4 product version) or can be connected to a local Matter compatible hub and work in local home automation system, without cloud connection. Thanks to the support of the Matter standard, it is compatible with Google Home, Alexa  and Apple Home.


Note: MINI R4M (as opposed to MINI R4) does NOT support “eWeLink-Remote“, a Sonoff’s proprietary Bluetooth protocol for local remote control, Bluetooth is only used in the Matter version for APP pairing.

Just as all other eWeLink relay modules, it supports scedules ON/OFF, power-on-state (ON / OFF / LAST STATUS / REVERSE 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, IFTTT (needs eWeLink Advanced subscription) and SmartThings system, as well as, Apple Home.

Richard McClintock, a Latin scholar from Hampden-Sydney College, is credited with discovering the source behind the ubiquitous filler text. In seeing a sample of lorem ipsum, his interest was piqued by consectetur—a genuine, albeit rare, Latin word. Consulting a Latin dictionary led McClintock to a passage from De Finibus Bonorum et Malorum On the Extremes of Good and Evil, a first-century B.C. text from the Roman.

So when is it okay to use lorem ipsum? First, lorem ipsum works well for staging. It’s like the props in a furniture store—filler text makes it look like someone is home. The same Wordpress template might eventually be home to a fitness blog, a photography website, or the online journal of a cupcake fanatic. Lorem ipsum helps them imagine what the lived-in website might look like.
