This Recommendation provides the requirements and architecture of home energy management system (HEMS) and home network (HN) services. The HEMS supports energy efficiency and reduction of the energy consumption. It is performed by monitoring and controlling the 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 the reduction of the energy consumption runs in the HEMS application, the development of the platform (PF) has been desired which provides common functions to enable the application to access to the devices and support the application developers to develop the application efficiently. This is not only for the HEMS but also for the 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 as one of the HN services. It also describes the reference architecture and the functional architecture including functional relationship for the HEMS and the other HN services.
