Wall smart switch Sonoff MINIR4M-E Matter-compatible Wi‑Fi control, 4-gang

The SONOFF MINIR4M-E (Orb-MW1) is a 1-channel Matter-compatible wall switch from the Fusion series designed for indoor use. It features a minimalist white PC housing, local control independent of the internet, and the Detach Relay mode that leaves smart bulbs powered when the switch is turned off. The switch uses an ESP32-C3FN4 microcontroller, supports 2.4 GHz Wi‑Fi (IEEE 802.11 b/g/n) and is suitable for resistive loads up to 10 A. Dimensions are 86 × 86 × 34 mm and the unit weighs 84 g.

Advantages

The Orb-MW1 integrates with Matter, enabling straightforward operation across Apple Home, Google Home, Alexa, SmartThings and Home Assistant through a common Matter hub. Local control ensures the switch continues to operate manually if the internet or router fails. Detach Relay mode keeps connected smart bulbs powered for continuous automation and voice control. The compact Fusion-series design and standard wire compatibility (16–14 AWG copper) simplify installation in typical indoor electrical setups.

How to use

Install the MINIR4M-E into a standard indoor wall box following local electrical safety rules and ensure power is switched off before wiring. Connect live and neutral conductors with recommended 16–14 AWG copper wire. After powering, add the device to your Matter-compatible hub or directly to supported platforms (Apple Home, Google Home, Alexa, SmartThings, Home Assistant) over 2.4 GHz Wi‑Fi. Use the switch mechanically for local on/off control; configure Detach Relay mode in the app if you want the bulbs to remain powered when the switch is off. Create automations, scenes or schedules in your Matter hub to link the switch with sensors or voice assistants.

Recommendations

For reliable operation, use 16–14 AWG copper wire and a stable Matter hub for cross-platform control. Keep the device within range of a 2.4 GHz Wi‑Fi network during initial setup. Do not install outdoors or in environments outside the specified temperature and humidity range.
