This means that reliable absence detection is possible for the first time. This information allows the reliable activation and deactivation of lighting without the need for stay ON times and without any waste of electricity. The detailed knowledge concerning presence and absence results in numerous other applications that can be very valuable for building management. This sets a new standard in advanced building automation.
