Sensor units

Modularity makes everything possible.

The ABB-free@home® range takes all important applications into consideration - switching and dimming of lights, detection of movement, control of blinds, scenes, heating, air-conditioning, door communication, remote access via smartphones and tablets as well as time functions.

The sensor units of the 1gang and 2gang rockers can be freely occupied with the functions of blinds, lights, dimming or scenes. Additional solutions are offered by the movement detector and room temperature controller, which have been specially developed for the ABB-free@home® range.

Light control.

Life begins with light. With ABB-free@home® it can be optimally used, whether for illuminating individual rooms or the entire house. For example, with striking light scenes - for different moods and to suit the occasion. A pleasant side effect here is the cost-saving and environmentally friendly use of energy.


Whether blind, roller blind, awning or roller door - with the ABB-free@home® home automation, sun protection and energy saving could not be easier. Opening and closing and the adjustment of lamella can be controlled with a switch, ABB-free@homeTouch, web interface or app for smartphone or tablet. In addition, a conventional weather station for protection during a storm, a timer or astro function can be used. It automatically adjusts the blind according to sunrise and sunset.

Heating and air-conditioning.

Providing comfort and energy-saving. The optimum room temperature can be adjusted with ABB-free@home® individually or according to the specific requirement. Depending on the time of day and the function of the room. In ECO mode, the temperature is automatically lowered at night or when the house is empty. The heating can be automatically shut off when the window is open. This reduces the consumption of energy - whether for conventional heaters or under-floor heating.

Door communication.

Most welcome. Also the ABB-Welcome door communication system can be integrated into ABB-free@home®. The door communication and the home automation can be used together with ABB-free@homeTouch 7". For example, the light switches on when the doorbell is rung to better recognize visitors. And for reasons of safety, the video camera records pictures of visitors at the door during one's absence.



Fast change of scene(ry). A single press of the button on the switch, on the ABB-free@homeTouch, PC, laptop, smartphone or tablet suffices to call up a complete scene. For example, the living room can be turned into a home cinema within just a few seconds. The roller blinds close. The lights in the room are dimmed. This comfort can be turned into reality with ABB-free@home® in every room.
