KNX is an open standard for home and building control, maintained by the KNX Association. Devices communicate through group addresses, so a switch can control a light without a central controller.
KNX
KNX is an open standard for home and building control, covering lighting, blinds, heating, ventilation, security and energy management. It is maintained by the KNX Association, which certifies devices from many manufacturers.
- Group communication - Devices send telegrams to group addresses, and every device listening on that address acts on them.
- No central controller required - A wall switch can control a light directly; logic is distributed across the devices.
- Several media - Twisted pair, powerline, radio and IP, with KNX IP routing and tunnelling for networks.
- One configuration tool - Installations from different vendors are configured with the same software.
For APIs, KNX usually appears through IP gateways and building platforms that translate group addresses into named, typed resources.
It is one of fourteen protocols mapped to five communication patterns in OT Fabric’s software architect’s guide to OT.
