Summary

Recommendation ITU-T Y.2070 provides the requirements and architecture of the home energy management system (HEMS) and home network (HN) services. The HEMS supports energy efficiency and reduction of energy consumption by monitoring and controlling devices such as home appliances, storage batteries and sensors connected to the HN from the HEMS application.

While the algorithm for the energy efficiency and reduction of energy consumption runs in the HEMS application, the development of a platform (PF) is desired which provides common functions to enable the application to access the devices and to support the efficient development of applications. This is not only applies for the HEMS, but also for other HN services such as home security and healthcare. This Recommendation provides common requirements for the HN services to support the HEMS as the widely known HEMS is mainly considered one of the HN services. It also describes the reference architecture and the functional architecture including the functional relationship for the HEMS and the other HN services.
