KNX

KNX is an international open standard for home and building automation that lets devices from different manufacturers communicate over one system. It connects lighting, heating, blinds, security and energy management so they operate together instead of as separate closed systems. Devices are planned and configured with the ETS software tool, and core functions run locally without depending on constant internet access.
