Universal Dimmer Control Element – motion detector

Enjoy convenient light that reacts automatically to movement. Together with the separately available universal dimmer insert, the control element forms a smart unit for automatic light control and convenient operation directly at the wall.

  • Automatic lighting control when movement is detected, depending on the ambient brightness, for more convenience in everyday life

  • Integrated PIR sensor with a detection range of up to 12 m as well as a twilight sensor for reliable detection of movement and ambient brightness

  • Two buttons for manual control of the lighting and other functions in the Homematic IP smart home system

Colour variants

The light switches on as you walk by exactly when you need it. 

For selective switching or stepless dimming, simply press the button on the wall. This provides clear orientation and straightforward handling.

Automatic light via integrated motion detection

Enjoy the convenience of never having to search for the light switch in the dark again when entering the room. The integrated sensor reliably detects movement and switches on the lighting fully automatically. This ensures maximum orientation and safety in walking areas such as hallways or staircases – especially when you don't have a hand free.

Two buttons for flexible manual operation

You retain control at all times, even with automatic light control. Use the two buttons on the wall to switch the light on and off as usual or adjust the brightness by pressing and holding. This allows you to spontaneously change the lighting mood at any time, completely independently of the motion detection.

Switches according to ambient brightness

An integrated twilight sensor measures the ambient brightness. This ensures that the light is only switched on automatically when motion is detected if it is too dark.

Perfect fit for 55 mm switch frames

The control element uses the standard 55 mm frame size and can be easily fitted into the frames of many well-known switch manufacturers.

FAQs - Your questions, our answers

In our FAQs you will find the answers to the most frequently asked questions - compact, easy to understand and always to the point. Find out everything you need to know to optimally control your smart home!

What is the Universal Dimmer Control Element – motion detector, and does it work even without the Universal Dimmer Insert?

The Universal Dimmer Control Element – motion detector combines automatic lighting control triggered by movement with manual push-button operation on the wall. It does not function independently but is securely attached to the mounting module of the flush-mounted dimmer insert via connecting pins.

How do motion detection and button controls work together with the Universal Dimmer Control Element – motion detector?

The Universal Dimmer Control Element – motion detector automatically turns on the light when motion is detected, as soon as the ambient brightness falls below a certain level. However, the two built-in buttons allow you to manually turn the lights on or off or dim them continuously at any time—completely independently of the motion detection.

Can other smart components be controlled using the Universal Dimmer Control Element – motion detector?

Yes, the two buttons provide flexible control functionality for the entire system. They are not only used to manually control the directly wired light fixture, but can also simultaneously switch other components or trigger entire lighting scenes with a single press.

What settings does the Universal Dimmer Control Element – motion detector offer?

Through the system settings, you can adjust detailed settings such as the minimum transmission interval, buffering of repeated movements, and a brightness filter. The brightness filter calculates the light level approximately every 6 minutes based on several measurements to ensure that short-term fluctuations—such as the lights of passing cars—do not cause the automatic system to trigger incorrectly. In addition, motion detection can be temporarily disabled.
