Japan's open standard "ECHONET Lite" has penetrated the world

　In Japan, there is a high need for energy saving in houses, and the technology of smart condominiums (houses) has continued to develop independently. rice field. "Since 2011, we have been discussing with the Ministry of Economy, Trade and Industry to build a HEMS (Home Energy Management System), converting home appliances and equipment to IoT, and developing the standard 'ECHONET Lite' to realize energy management. This standard has been introduced to the world as an open international standard (ISO/IEC 14543-4-3) originating in Japan, and is steadily spreading.”

As the director of the HEMS Authentication Support Center (Kanagawa Institute of Technology Education and Research Promotion Organization Smart House Research Center), Mr. Masao Isshiki, a professor at the same university's Faculty of Creative Engineering who has been working on the standardization, dissemination and enlightenment of related technologies, explains the background to this. look back.

One of the reasons why the "ECHONET Lite" standard has developed in Japan is that the experience of the Great East Japan Earthquake made us realize the importance of ensuring a stable supply of electricity. Mr. Isshiki says that the spirit of "mottainai" inherited from his ancestors and the meticulous national character of meticulously managing various devices are also related. “Like in Japan, interest in the ECHONET Lite standard is high in Asia as well, and in 2019, in Taiwan, a joint demonstration was conducted with a Japanese company in Tainan’s demonstration field, Sarun Green Energy Science City, to build a next-generation meter reading system. ECHONET Lite equipment is used,” says Isshiki.

On the other hand, even in Europe and the United States, where energy conservation awareness has been relatively low until now, interest in energy management is rapidly increasing in recent years. Professor Isshiki says, "Rather than from the perspective of energy conservation, the trend toward decarbonization, which is the reduction of fossil energy consumption, is having an effect."

　"Japan has been working hard to be a little more advanced than the rest of the world.From now on, it is important how we can get along with the rest of the world through this open standard.The spread of smart house technology will greatly contribute to the world. I believe this is a field where we can do it,” emphasizes Isshiki. The number of ECHONET Lite-compatible devices is steadily expanding, and by 2020, the target number of devices has exceeded 100 million.
