Sonoff Wi-Fi Smart Relay (Matter compatible - 10A / 2.4kW)

by Sonoff

MINIR4M / Mini Extreme is Sonoff's first Matter-enabled Wi-Fi smart switch designed for versatility, compatibility, and ultimate convenience.

Whether you’re upgrading your lighting or adding automation to your appliances, this pint-sized powerhouse is packed with features to make your life smarter, simpler, and safer.

Why We Love It

Smarter, smaller, and packed with features, the SONOFF MINIR4M is ready to transform your home. Take the next step into smarter living!

  • Matter-Enabled Marvel: Seamlessly integrates with Matter-enabled platforms like Alexa, Apple Home, and Google Home. Use voice commands via Alexa or Google Assistant, or enjoy remote control through the eWeLink app.
  • Detach Relay Mode: Smarter Switching: The “detach relay” mode allows the external switch and relay to operate independently. Toggle your wall switch without affecting the relay state—perfect for flexible, custom setups.
  • Switch It Your Way: Compatible with a variety of external switches, including momentary, door exit, SPDT, latching, and dry contact sensors. Whatever your setup, this smart switch connects seamlessly.
  • Share the Smarts: Easily share control with family and friends via the eWeLink app. Whether they’re turning devices on and off or checking their status, everyone can enjoy the convenience of a smart home.
  • Tiny but Mighty: Measuring just 39.5×33×16.8mm, it fits snugly into even the smallest 86/EU-type mounting boxes.

Compact. Clever. Connected. 💡✨

Tech Specs

  • Connectivity: 2.4GHz Wi-Fi 802.11 b/g/n
  • Power: 100–240V @ 50/60Hz (10A max)
  • Dimensions: 39.5×33×16.8mm

What is Matter?

Matter is the clever new kid on the block for smart home connectivity, created by the Connectivity Standards Alliance (CSA) – the same organisation behind Zigbee and Z-Wave. In collaboration with tech giants like Amazon, Apple, Google, and Samsung, Matter was developed to address two major challenges:

  1. Compatibility Chaos: Devices that don’t work well together across different manufacturers or controllers.
  2. Security Woes: Vulnerabilities, unreliable updates, and cloud dependency leaving smart homes exposed.

While Zigbee and Z-Wave led the way for low-power, low-cost IoT devices, Matter takes it further. It provides seamless communication across devices and platforms while ensuring airtight security.

Based on Project Connected Home Over IP (CHIP), Matter is an IP-based, open-source IoT standard. It enables manufacturers to create secure, interoperable, and easy-to-use devices. Whether it’s lights, locks, or thermostats, if it’s Matter-certified, it’s designed to work seamlessly with any Matter-compatible controller or platform.

In short, Matter just… works. No faffing, no worries – just smart devices doing what they’re supposed to do, together.

A bit overpriced in comparison of most other BME680 sensors available online but with this one, you're sure it's working with the Adafruit libraries. I had this issue when buying 2 BME280 sensors from China, one of the two was actually a BMP280 in stead of BME280 so, it couldn't work with the library even if written on the article description as compatible.

Love the BME680. Very easy to install and the Example files are great for getting started. Have found out from this Pimoroni Forum post : https://forums.pimoroni.com/t/bme680-air-quality-low/6293/9 that the whole AQ subject is very complex, however It's a really interesting topic and one that I am looking forward to understanding better! I'd assumed that it was only detecting VOCs (volatile organic compounds) but there's a hint that it might be detecting other gases. (I'm using a Breakout Garden pHAT with PiZero W, BME680 and 11x7 matrix to show an AQ score.)

I appreciate the thought put into the design of this board. It is nice that the pins line up with the GPIO, it’s easier to assemble and more presentable to have around the house. I also appreciate that their software has a “try” statement that looks for an Adafruit addressed chip as well as this Pimoroni one, since I have a mix of both around. Very good product, very much recommend it!

The board is high quality and easy to mount (on a featherwing proto) - note to Pimoroni (perhaps you could develop sensors already mounted on featherwing format?). The driver software is a little harder to get working than I expected - still can't see have to get the AQI (air quality index) as an output from the Bosch library or through the wrapper Adafruit library.

I am glad I lived long enough to see this awesome technology! I was a bit out of practice with the soldering iron but even I managed to sort out the connection to the Raspberry Pi. It is now being used to monitor the environment in conjunction with a ground source heat pump via Home Assistant. Thank you very much!

Very nice all in one sensor for most basic Environmental sensors. The Air Quality sensor (Gas Ohm resistance detection) does take awhile to stabilize (at least 20 min on first start, about 5 for ones after that). It might get better as I use it more, as I only used it for about 12 hours.

Up and running in minutes after a false start but recovered quickly owing the prompt technical support. Good excuse to refresh minimal soldering skills. Robust module supersedes previous models. Temperature (with humidity) sensors are a dime a dozen, the barometric sensor is an added plus but the air quality sensor is the deal breaker for the price.
