Brightness calibration
Different light sources may have different response ranges to brightness changes. The automatic or manual calibration function helps match the dimmer's operation to the specific fixture, resulting in more stable performance and smooth, flicker-free dimming.

Energy monitoring
The device continuously detects and synchronizes energy consumption data, allowing the user to monitor the power draw of the connected circuit in real time. This is a practical feature that supports optimizing lighting operation and controlling energy usage.
Overheating protection
A built-in NTC sensor monitors the device's operating temperature. If overheating is detected, the dimmer automatically cuts off the power, protecting both the module and the connected lighting.
Personalized automation
Precise brightness adjustment allows for building lighting scenes tailored to daily needs. The MINI-DIM can be used to automatically set lighting levels based on the time of day, user activity, or a selected smart home scenario.
Wiring instructions
The dimmer is designed for in-wall mounting indoors. Installation must be performed according to the manufacturer's diagram.
