KNX is a standardized communication protocol used for building automation. It allows various devices, such as lights, heating systems, and security systems, to communicate with each other, enabling centralized control and automation in homes and commercial buildings. This interoperability helps improve energy efficiency and user comfort. The KNX system is based on a decentralized architecture, meaning there is no single point of failure. Devices can be added or removed easily, making it flexible for future upgrades. It is widely adopted in Europe and recognized globally, ensuring compatibility across different manufacturers and products.
