Smart switch Sonoff MINIR4M Wi‑Fi HomeKit SmartThings, 4‑channel mini module

Sonoff Smart Switch MINIR4M is a compact 4-channel Wi‑Fi smart switch module designed for in‑wall or behind‑device installation. It supports Matter and integrates with platforms such as Amazon Alexa, Apple Home (HomeKit), Google Home and SmartThings, allowing independent control of up to four circuits or loads. The miniature housing fits into small enclosures including 86/EU type boxes, while TÜV, CE and FCC certifications confirm compliance with safety and electromagnetic standards.

Advantages

The MINIR4M offers Matter compatibility for cross-brand interoperability, four independent channels for separate load control, and a very small form factor suitable for tight installation spaces. It supports multiple external switch types and includes a relay disconnection mode that separates external switch state from relay state. Certified by TÜV, CE and FCC, the module provides reliable operation for lighting and small appliance control over standard 2.4 GHz Wi‑Fi.

Suitable for

• Controlling multiple lighting circuits behind switches or in junction boxes
• Automating small household appliances and fans
• Integration with Alexa, Apple Home (HomeKit), Google Home or SmartThings ecosystems
• Retrofit installations where space is limited (86/EU boxes and similar)

How to use

Install the MINIR4M inside a wall box or behind the fixture following local electrical regulations and turn off power before wiring. Connect line and neutral wires and route the four channel outputs to the controlled loads. Configure external switches if required — the module accepts momentary, SPDT, latching and potential‑free contacts and can operate in relay disconnection mode to separate switch state from relay state. Add the device to your chosen Matter‑compatible ecosystem or Sonoff app over 2.4 GHz Wi‑Fi, then assign channels, create schedules or voice control routines.

Usage recommendations

Use the MINIR4M for low‑to‑medium power loads such as lighting circuits and small appliances within the 10 A per channel rating. Ensure installation by a qualified electrician in compliance with local codes and keep the device in an environment within the manufacturer’s specified temperature and humidity ranges. For reliable network operation, connect the module to a stable 2.4 GHz Wi‑Fi network and consider configuring automation rules in the chosen smart home platform.
