KNX is a standardized, OSI-based network communications protocol for intelligent buildings.

KNX is the successor to, and convergence of, three previous standards: the European Home Systems Protocol (EHS), BâtiBUS, and the European Installation Bus (EIB or Instabus). The KNX standard is administered by the KNX Association.

KNX defines several physical communication media:

  • Twisted pair wiring (inherited from the BatiBUS and EIB Instabus standards)
  • Powerline networking (inherited from EIB and EHS - similar to that used by X10)
  • Radio (KNX-RF)
  • Ethernet (also known as EIBnet/IP or KNXnet/IP)
