The SONOFF Orb-DIM (MINI-DIM-E) is an ultra-compact, in-wall smart dimmer relay with an integrated wall switch, designed to add smart control to your existing lighting circuits via Matter over Wi-Fi. The dimmer provides smooth, flicker-free dimming for most 230 V dimmable light sources (including LED, incandescent, halogen bulbs, and dimmable electronic transformers), making it easy to integrate traditional lighting into a unified smart home system.
Measuring just a few centimeters, the module fits neatly behind your wall switch and retains manual control with both momentary push-buttons and rocker switches supported. Its built-in auto and manual calibration enables accurate percentage-based brightness control, while overheat protection and power detection improve safety and compatibility.
Thanks to the Matter standard, the SONOFF Orb-DIM (MINI-DIM-E) is compatible with major ecosystems like Apple Home, Google Home, Amazon Alexa, SmartThings, and Home Assistant (Matter). You can configure schedules, scenes, and automations, and the fast plug-and-play pairing guides you through setup. The module requires a neutral wire and is intended for use only on single-phase (220–240 V~) networks.
