Sonoff MINI DIM Matter Wi-Fi Smart Dimmer Switch | MINI-DIM
The SONOFF MINI DIM is an ultra-compact in-wall smart dimmer from the MINI Extreme series. It installs behind your existing wall switch and lets you dim dimmable LED, incandescent and halogen lamps from the app, by voice or with the wall switch, with Matter over Wi-Fi support for Apple Home, Google Home, Amazon Alexa, SmartThings and Home Assistant.
Color: White

Wide Lamp Compatibility: MINI DIM uses trailing-edge dimming and supports dimmable LED lamps up to 200VA, incandescent and halogen bulbs up to 400W, and dimmable electronic transformers up to 200W.

Brightness Calibration: Different lamps respond differently to dimming. Automatic calibration (from the app, or by holding the device button for 10 seconds) adapts the dimming range to your lamp for smoother, more stable brightness control. SONOFF recommends calibrating before use.

Power Monitoring: The dimmer reports the real-time power of the connected lighting in the app as you change the brightness.

Wall Switch Control: Two switch inputs (S1 and S2) let you keep using rocker switches or push buttons. Depending on the switch mode, the wall switch can turn the light on/off or raise and lower the brightness; set the switch type first by triple-pressing the device button or in the eWeLink app.

Smart Control: Matter support lets you add MINI DIM to Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, which all support on/off and brightness. In eWeLink you also get timers, schedules, scenes and LAN control without a server connection.
Safety: An NTC temperature sensor triggers overheat protection that cuts the output when the device gets too hot. The housing is flame-retardant PC.

Who it's for / Works with: Anyone who wants dimmable lighting without replacing the wall switch. Works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant via Matter, and with the eWeLink app.
Good to know: For 220–240V 50Hz supplies only. A neutral wire is required and installation must be done by a qualified electrician. Use only dimmable lamps. Integration with a Matter ecosystem requires a Matter hub. 2.4 GHz Wi-Fi only.
