The KNX smart home system offers a big plus in convenience, security and economy both in private dwellings and commercial construction. All the house functions and numerous multimedia functions can be networked together and controlled centrally with the KNX intelligent building system technology. The visualization and evaluation of energy consumption, the Smart Metering, can also be implemented easily with KNX technology. The function of the individual components is determined by their programming, which can be changed and adapted at any time. What this means for the user is a convenient and flexible form of building technology that can be customized to meet his or her individual needs.
