Product detailed description

💡 Sonoff DIM - Matter Dimmer for 230V Lights

The Sonoff Mini Extreme Dim is designed to fit behind a standard wall switch, allowing smart dimming of most 230V dimmable light sources (supporting dimmable LEDs up to 200W, incandescent and halogen bulbs up to 400W, and dimmable electronic transformers up to 200W) – making it easy to integrate traditional lighting into a unified smart home system.

Smooth Calibrated Dimming

Part of the SONOFF Mini Extreme series, the module is only a few centimeters in size and retains manual control via physical switches (supports both push-button and rocker switches). Different lamps have different dimming ranges. Built-in automatic and manual calibration allows precise percentage-based dimming, ensuring a better match between the dimmer and your light fixtures. It identifies the true brightness response range of the lamps for stable, flicker-free dimming.

*Please perform brightness calibration before use.

Various Switch Types

Highly flexible and compatible with various types of external switches, allowing not only ON/OFF but also step-by-step brightness adjustment.

*If you want the switch to match your external switch, please set the switch mode first: press the device button three times or select it in the eWeLink app.

Built-in Overheat Protection

Safety features such as integrated temperature detection, which triggers user interface alerts and automatically cuts power output if overheating occurs (protecting both the device and connected lighting), along with load detection, enhance compatibility and reliability.

Smart Matter Ecosystem Support

Thanks to Matter support, the MINI-DIM seamlessly integrates with major smart home platforms such as Apple Home (Siri on iPhone/iPad/Apple Watch), Google Home, Amazon Alexa, SmartThings, and Home Assistant (via Matter). You can set schedules, scenes, and automations with simple Plug & Play pairing. A neutral wire is required, and the module is only suitable for single-phase 220–240V~ AC networks.

*For integration with the Matter ecosystem, the MINI-DIM requires a Matter Hub. 

Real-time Energy Monitoring

It continuously detects and synchronizes energy consumption data, providing a clear real-time overview of power usage. This allows you to see exactly how much energy your lights are drawing at different brightness levels - enabling efficient consumption management and monitoring.

Dual Location Control

The MINI-DIM allows the connection of two external switches (momentary or rocker) to control the same light from two different locations, making it ideal for use in hallways or staircases. You can customize the switch modes in the app (or directly on the device) for intuitive use.
