The KNX bus is a system independent of manufacturers and application areas. By connecting all bus devices to KNX media (including twisted pair, radio frequency, power lines, or IP/Ethernet), they can exchange information. Bus devices can be sensors or actuators used to control building management devices such as lighting, shading/louvers, security systems, energy management, heating, ventilation, air conditioning systems, signal and monitoring systems, service interfaces and building control systems, remote control, metering, video/audio control, large household appliances, etc. All these functions can be controlled, monitored, and signaled through a unified system without the need for additional control centers.
