This is the way to total living comfort. As the sun sets, outside lighting switches on; the washing machine is started via remote control; and even when you are on vacation, your house gives the impression of activity. Modern digital installation technology lets you plan and program all this according to your habits, comfort and security requirements.   

Two types of data transfer

• In conventional bus systems, information lines are laid along with the necessary power supply. This data highway enables electronic control of and communication between all appliances and devices (with special microchips) in the house. The microchips serve as the intelligent connection and handle all switching and feedback functions. 
• Relatively new are wireless systems. The switching device is mounted in a wall, a lamp cover, or in the ceiling, and switches are mounted on walls. The advantage is that wiring is not necessary.

Application

• Depending on their programming, both systems can execute individual commands or trigger and combine complete programs (e.g., networked smoke detectors whose activation switches on all lights and opens blinds of possible emergency exits). 
• The bus system can be programmed flexibly and modified or extended any time. 
• The system is operated via a PC or tablet. 
• A glance a the monitor reveals whether the garage door is locked, where light is on in the house, etc. 
• If you select a KNX/EIB installation, then you are not bound to a vendor. KNX/EIB compatible devices from different manufacturers can be combined.

Security (see section Property protection)

• The bus system lets you combine individual motion detectors at doors and windows with one another and with other sensors. This enables efficient security monitoring. 
• Unwanted guests trigger the automatic alarm system (e.g., turn on lights inside and outside). 
• Door and window contacts activate a telephone alarm. 
• Even when you are on vacation, appropriate programming gives the impression that you are home. 
• If you are building a new home and have not decided to install a bus system, at least provide the conduit to facilitate later installation. 
• Retrofitting is possible, even as a modular system.
