SONOFF MINIR4M Matter Smart Switch 4 Pack - Compact Matter Module

In this review the SONOFF MINIR4M Matter Smart Switch is evaluated as a compact, versatile relay module for users who want native Matter integration and a small in-wall footprint. It is best for homeowners or installers seeking a discreet module that fits into the smallest 86/EU boxes and works across Matter-enabled platforms like Alexa, Apple Home and Google Home. The single biggest reason to buy is its Matter compatibility, which lets it join a multi-vendor smart home and be controlled from a single platform without relying solely on a proprietary cloud.

Key Features

• Matter Certified: Native Matter support allows the MINIR4M to integrate with other brand devices and control from Apple Home, Google Home, Alexa and other Matter platforms.
• Mini Size: The compact module fits into small mounting boxes including 86/EU type enclosures, making retrofits and tight installs straightforward.
• External Switch Control: It accepts momentary, latching, SPDT and dry contact sensors so it can work with a wide range of wall switches and access controls.
• Detach Relay Mode: The detach relay mode separates the physical switch state from the relay state so manual presses do not unintentionally change the relay output.
• Safety Certifications: TUV, CE and FCC certifications provide added assurance of regulatory compliance and electrical safety for in-wall use.

Who It's For

The MINIR4M is ideal for DIYers and electricians upgrading conventional wiring to a Matter-based smart home without changing switch hardware; its small size and multiple supported switch types make it a good choice for crowded backboxes and diverse switch panels. It is also suited to anyone who wants to centralize control across platforms and avoid vendor lock-in by using the Matter ecosystem.

It is not the best choice for installations lacking a neutral wire, since a neutral is required, nor is it intended for users who need a standalone WiFi-only module without Matter integration. Those needing a mains solution without any neutral connection should consider alternate products.
