Abstract
This chapter describes commercialized systems for the smart home market in Asia. In particular, it focuses on the deployment power of the open standard (ECHONET Lite)-based business. ECHONET Lite is an open network protocol, which can be beneficial for society in the twenty-first century. Since the types of network-connected devices are increasing and home network services are diversifying, there is a growing need to make it easier to build home networks. It was therefore decided to develop ECHONET Lite, which is a transport-free network protocol so that developers can select communication media that they want to use. In this one year, ECHONET Lite has brought innovation to EMS. In terms of a power meter, since JSCA, government-industry collaboration in Japan, decided to adopt ECHONET Lite over IPv6 as the standardized communication interface to a power meter, all of Japan’s power meters, exceeding over 48million, have been functionalized as a home appliance, delivering electric consumption data to homes: voltage, ampere, watt-hour, log-data. ECHONET Lite is designed to be easier for home network system builders and service system developers. Not only network protocols but also the definition of control commands is very important for the interoperability between multivendors. Therefore, ECHONET Lite has defined control commands for about 90 devices to realize multivendor interoperability. Typical devices included are air conditioners, lighting, fuel cells, photovoltaics, storage batteries, heat pump water heaters, EV/PHV, and smart meters. The following five themes are explained. 1.Overview of smart home businesses today2.Overview of ECHONET Lite (International Open Standard for Home appliances and utilities)3.Overview of smart house businesses 1: Panasonic Activities4.Overview of smart house businesses 2: Toshiba Activities5.Open source software and related activities for ECHONET Lite with web technologies
