Homematic IP motion detector and wall switch for frames with internal dimensions of 5.5 x 5.5 cm This switch offers several options for controlling the assigned Homematic IP components. A light that is integrated into Homematic IP can be controlled by the two-button switch or the motion detector. The latter is optionally only active if the integrated twilight sensor registers an ambient brightness below a defined threshold value. The motion detector can also be used to trigger alarm sirens.
