Energy services interface

The Energy services interface (ESI) is a special class of device. It is network-centric and can also be thought of as a gateway. It provides security, and often, coordination functions that enable secure interactions between relevant home area network devices and the electric power company. It permits applications such as remote load control, monitoring and control of distributed generation, in-home display of customer usage, reading of non-energy meters, and integration with building management systems. It also provides auditing/logging functions that record transactions to and from home area networking devices.
