Sonoff MINIR4M In-Depth Review (2026): The Aging Matter Champ?

Last updated on February 28, 2026

Years after its initial 2023 launch, the Sonoff MINIR4M has become a certified veteran in the smart relay space. What was once a groundbreaking, affordable entry into the Matter standard now faces a much more mature and crowded market. In this Sonoff MINIR4M review for 2026, we’ll break down its performance, long-term reliability, and whether—after years of firmware updates—it’s still a smart buy for your Home Assistant setup.

Sonoff MINIR4M: The Core Features That Still Matter in 2026

While the smart home landscape has evolved, the MINIR4M holds onto a core set of features that keep it relevant, especially at its rock-bottom price. Its main selling point has always been its incredibly compact size, which allows it to be tucked away in almost any electrical box, even the most crowded ones.

Here’s where it still shines today:

• Ultra-Compact Size: It remains one of the smallest relays on the market, making installation a breeze.
• “Detach Relay” Mode: This feature is a game-changer for smart bulb users. It allows the physical wall switch to control the bulbs via Home Assistant without actually cutting their power, keeping them online and responsive at all times.
• Matter-Enabled: This is its killer feature. Matter allows for native, local integration with ecosystems like Home Assistant, Apple Home, Google Home, and Amazon Alexa without relying on third-party clouds or clunky skills.
• No-Neutral Required (with adapter): While the base model needs a neutral wire, Sonoff later released an accessory that allows it to work in older homes without one, greatly increasing its versatility.

Matter 2.0 Integration with Home Assistant: Smooth Sailing in 2026

The experience of integrating the Sonoff MINIR4M has improved dramatically, thanks to the maturity of the standard—now on version Matter 2.0—and robust support from Home Assistant. Unlike the early days where pairing could be a frustrating mess, the process in 2026 is refreshingly smooth.

To add it to Home Assistant, all you need is a Matter/Thread Border Router, like the one built into Home Assistant Yellow, Green, or a dongle like the Sonoff ZBDongle-P/E flashed with the right firmware. The process is as simple as scanning the QR code on the device from the Home Assistant Companion app and following the prompts. Once added, the relay shows up as a standard switch entity and responds almost instantly, thanks to local Matter communication over Wi-Fi.

Long-Term Reliability: Common Sonoff MINIR4M Problems After Years of Use

With several years on the market, the community has had plenty of time to pinpoint this device’s weaknesses. While it’s generally reliable for the price, here are a few Sonoff MINIR4M problems I’ve either experienced myself or seen reported frequently:

• Wi-Fi Sensitivity: As a Wi-Fi device, its stability is 100% dependent on the quality of your network. In congested networks or areas with spotty coverage, it can drop offline occasionally. A solid network, ideally with a dedicated VLAN for IoT devices, is non-negotiable.
• Firmware Update Dependency: Keeping the Sonoff firmware updated is critical. The first few firmware versions were notoriously unstable. It’s essential to update it via the eWeLink app (even if you only use the app for this one task) before integrating it into a local ecosystem to ensure maximum compatibility and security.
• Overheating Concerns: Under loads approaching its 10A limit, the device tends to run warm. While it’s within its rated safety margins, I always recommend against pushing it to the absolute max. Use it for more moderate loads like lighting and fans.

eWeLink vs. Home Assistant: The 2026 Showdown

It’s the age-old question. While Sonoff’s eWeLink app is functional for a basic user, it pales in comparison to the power, privacy, and control of a local system. In the eWeLink vs. Home Assistant debate, Home Assistant wins by a landslide for any user serious about building a real, cloud-free smart home.

My recommendation is clear: use the eWeLink app only for the initial setup and to apply any pending Sonoff firmware updates. Once that’s done, add it to Home Assistant via Matter and forget the Sonoff cloud exists for daily control. You’ll get better speed, total privacy, and automation possibilities the manufacturer’s app can only dream of.

Sonoff MINIR4M vs. The 2026 Competition

The in-wall relay market has exploded. The MINIR4M is no longer just competing with its Zigbee siblings, but with a whole new generation of devices. Here’s a quick Matter relay comparison with some popular alternatives in 2026.

Price and Where to Buy in 2026

As of 2026, the Sonoff MINIR4M can typically be found for around $12, cementing its position as one of the cheapest ways to get started with Matter. It remains an excellent value, especially for projects that require deploying multiple units without breaking the bank.

As always, your best bet is to buy it directly from the manufacturer’s website to ensure you’re getting the latest hardware revision and official support.

The Verdict: Is the Sonoff MINIR4M Still Worth It in 2026?

After this deep-dive Sonoff MINIR4M review for 2026, the answer is a resounding yes, but with a few caveats. If you’re looking for the absolute cheapest in-wall relay with Matter support, a dead-simple installation, and the incredibly useful “detach relay” mode, the MINIR4M is still almost impossible to beat.

However, if your Wi-Fi network isn’t rock-solid or you’d rather explore the benefits of low-power mesh networks like Thread, options like the Aqara T2M might be worth the extra cash. For the vast majority of Home Assistant users looking to automate their lighting reliably and on a budget, the Sonoff MINIR4M has aged remarkably well and remains a solid recommendation in my smart home toolkit.
