This document specifies an open and extensible standard for residential, commercial, and industrial control and automation applications using the EN 14908-1 control network protocol and related protocols (EN 14908-2 to EN 14908-9) to provision and manage IoT devices, to access and update data from the devices, and to aggregate data from diverse devices and protocols for delivery to external applications and services. The web services as specified in this document are typically implemented on a central gateway or edge server that communicates with multiple sensor, actuator, and controller edge devices using one or more drivers such as EN 14908-1, and typically also interfaces with one or more enterprise and cloud services or applications.
