The SONOFF MINI-DIM is an ultra-compact, in-wall smart light dimmer that brings Matter over Wi-Fi connectivity to your existing lighting circuits. Designed to fit behind a standard wall switch, it enables smart dimming control for most dimmable 230V light sources (LEDs, incandescent, halogen, dimmable electronic transformers) – allowing easy integration of traditional lighting into a unified smart home system.
Part of the SONOFF Mini Extreme series, the module is just a few centimeters in size and retains manual control via physical switches (supports both push-button and toggle switches). Built-in auto and manual calibration enables precise percentage-based dimming. Safety features like overheat protection and load detection enhance compatibility and reliability.
Thanks to Matter support, the MINI-DIM integrates seamlessly with major smart home platforms such as Apple Home, Google Home, Amazon Alexa, SmartThings, and Home Assistant (via Matter). You can set schedules, scenes, and automations, with a simple Plug & Play pairing experience. A neutral wire is required, and the module is suitable for single-phase 220–240V~ AC networks only.
