ECHONET Consortium activities are carried out by the three committees. Their objective: to develop standards for transmission media, which comprise the physical basis for the home network; middleware, which facilitates development of service applications; and service middleware, which performs linkage with external systems.

The ECHONET Consortium was established in 1997 with the aim of creating an abundant 21st-century society where people and the environment live in harmony. The Consortium marked its 20th anniversary in 2017, thanks to your kind efforts and cooperation.
Meanwhile, the Consortium has promoted the establishment of standard specifications for a home network infrastructure that is capable of interconnecting home appliances, facility devices, sensors, and controllers supplied by multiple vendors, to cope with environmental issues, energy problems, CO2 emission reductions, and an aging society.
After being released in 2011 to allow linkages with standard protocols both inside and outside of Japan, the ECHONET Lite specifications were recommended as a publicly-known standard interface for HEMS. This took place at the Smart Community Alliance International Standardization Working Group Smart house Standardization Investigation Committee meeting held the following year, and the specifications were approved as international standard in 2015. After that, following the establishment of the ECHONET Lite AIF Specifications which is to achieve a full interoperability between devices supplied by multiple vendors and the start of the certification program in 2016, an increasing number of more devices, especially the eight key devices (air conditioners, storage batteries, hot water supply systems, solar power generation, fuel cells, lighting, smart electric meters, and EV/PHV chargers) , have been installed with ECHONET Lite specifications. Moreover, the Consortium strengthened collaboration with the Japan Electrical Manufacturers’ Association (JEMA) and the Japan Federation of Housing Organizations (JUDANREN) in 2016 to promote activities to spread ECHONET Lite, creating a “House Performance Catalog”.
Thanks to efforts made by ECHONET Consortium member companies, the number of products that have satisfied the requirements of ECHONET Lite specifications reached 94.06 million at the end of FY2019. Meanwhile, the number of device object definitions reached 116 models. Now, the scope of ECHONET Lite applications is further widening to include not only general households, but some commercial-use equipment as well.
In recent years, the use of IoT (connecting a large number of devices through the internet) is becoming more common, backed by the rapid development of cloud computing. To achieve a super-smart society through Cyber Physical Systems (CPS) where tangible objects in the real world are connected to the cloud, while intangibles in the form of a variety of services in virtual space on the cloud are spreading, the ECHONET Consortium has advocated ECHONET 2.0 as a new strategy. This is to evolve ECHONET Lite as a platform to realize a wide variety of services through research and development to find the ideal way of linking between services in the cloud-oriented age.
We are committed to promoting activities to help create an abundant and sustainable society through the creation of new added-value, such as Society 5.0 through ECHONET 2.0, in addition to activities to spread ECHONET Lite specifications and ECHONET Lite AIF specifications. With that, we hereby appreciate your ongoing support and cooperation.
The Steering Committee is engaged in a comprehensive range of activities to ensure the efficient and smooth operation of the ECHONET Consortium as a whole. Its responsibilities include planning, budget management, and administration of general assemblies and forums. It is also responsible for organizing each committee and working group and coordinate overall operation.
The Technical Committee is engaged in the development and operation of specifications of ECHONET Lite and study of the interoperability including the conduct of Plug Fest as technical activities relating to the basic technology of equipment home network. It also formulates the ECHONET Lite Web API Guidelines, develops and operates the testing environment and tools for service development to follow when services use the ECHONET Lite devices.
The Promotion Committee is engaged in public relations to promote further use of ECHONET Lite and ECHONET Lite Web API developed and standardized by the ECHONET Consortium. It is also involved in the conduct of seminars and symposium, and operation of the exhibiting at exhibitions. It is also working with other standardization organizations and conducting surveys in order to expand the spread of the ECHONET Lite Standard.
