SONOFF MINI-D - Smart WiFi dry contact module with Matter

Introduction

The SONOFF MINI-D is a revolutionary smart WiFi module with a dry contact output, the first of its kind to support the Matter protocol. Designed to transform your existing electrical installations into smart systems, it stands out with its dual AC/DC power supply and configurable NO/NC dry contact output. Ultra-compact like all modules in the MINI series, it allows remote control of garage doors, boilers, access systems, solenoid valves, or small DC motors up to 8W. Matter-compatible, it integrates seamlessly with Apple Home, Google Home, Alexa, Home Assistant, and all Matter-certified ecosystems for truly unified home automation.
