One interface for several systems
When each technical system has its own app, the user has to remember where to control the lighting, where the temperature and where multimedia or security functions. KNX visualisation can bring the most important controls and statuses together in a common structure. From the same interface you can, for example, select lighting scenes, change the temperature of a zone, check the position of the blinds or control audio/video functions.
Integration does not mean that everything has to be on one screen: a good interface organises information by room, function or scene so that the user can find their way quickly, without unnecessary technical detail.
