Organization and activities

The ECHONET Consortium was established in December 1997 with the aim of creating an abundant 21st-century society where people and the environment live in harmony and to develop and disseminate standard specifications for home network infrastructure technologies, which enables various devices to be interconnected.

As described in Membership and qualification in Membership and qualification System, companies that have interest in ECHONET can join us as general members and educational organizations that have interest in ECHONET can join us as academic members, regardless of nationality. Individuals who have attended a technical seminar and received certification can obtain ECHONET IoT MASTER qualification. The managing members are companies recognized as being able to make technical contributions to ECHONET.

By connecting devices from different manufacturers with the ECHONET Lite specifications, not only energy saving but also home security, home healthcare, remote control and monitoring of home appliances can be utilized, and a more comfortable, safer and more secure life becomes possible.

ECHONET Lite is a “shared language” that enables communication of IoT home appliances, housing equipment, energy generation and storage equipment provided by different companies.

It will be a “shared language” for connecting devices from different companies and will become a standard specification for home network infrastructure technology for responding to environmental problems, energy problems, reduction of CO2 emissions, and an aging society.

There are roadmaps such as “Define 200 types of device control commands by 2025” and “Service examples by ECHONET Lite Web API; 50 cases by 2030”. For details, see “Roadmap for promoting popularization.”

In addition, with the expansion of standards, ECHONET Consortium is sequentially proceeding with maintenance of international standards.


In order to acquire a certain level of skill, it is necessary to take the course for two consecutive days.

It is to take the entire two-day technical seminar curriculum and pass the “skill check test” conducted by an accredited educational institution. For details, please contact the authorized educational institution listed in ECHONET IoTマスター制度について (only in Japanese).

At the moment, the only certified educational institution is the Internet Academy, but ECHONET Consortium plans to increase it in the future.

Development, standards, licenses

The ECHONET Lite specifications will be revised as necessary. The addition and modification of ECHONET device objects and service objects will be developed by soliciting proposals from members twice a year and focusing on the Smart EMS Study WG.

For general members, there is no fee to adopt the standard if you pay the membership fee. In order to sell products that adopt the standard, it is necessary to obtain a certification registration number through an accredited certification body, so that fee will be incurred. There is also a fee to test at an accredited testing organization.

ECHONET Consortium provides ECHONET Lite Web API-related tools, but not software. Some general members provide middleware, development support tools, maintenance tools, etc., so please contact them directly.

You will install or support a communication system that conforms to the standards and develop software (application) based on the standards. General members have companies that support development, so please contact them if necessary.

ECHONET consortium itself is not patented. ECHONET Consortium believes that anyone wishing to adopt the ECHONET specifications should be able to reasonably and non-discriminatory use the intellectual property rights necessary to commercialize products that comply with these specifications. Of these intellectual property rights, the handling of patent rights and utility model rights, which are technically unavoidable in order to satisfy this standard, is stipulated in the Regulations on the Handling of Intellectual Property Rights, so please refer to that for details.

You need to become a member and obtain a Member ID/Manufacturer code. In order to sell equipment and services that have adopted the specifications, it is necessary to obtain a certification registration number through an accredited certification body.

There are AV-related equipment such as TVs, cooking / home appliances-related equipment such as rice cookers, and air-conditioning-related equipment such as home air conditioners. For details, refer to the ECHONET standard APPENDIX Detailed Requirements for ECHONET Device objects.

ECHONET Consortium conducts a Plug Fest to check compatibility. ECHONET Consortium is also working with industry groups to formulate interface specifications for the eight key devices such as smart meters.

It is not specified. In the ECHONET Lite specifications, as the 4th layer and below of the OSI reference model can be freely selected, popular transmission media can be used.

Even non-members can download the interface specifications for application layer communication. However, the certification test specifications corresponding to the specifications are available only to ECHONET Consortium members.

ECHONET Lite specifications certification

Please submit the “Member ID/Manufacturer code application” in Various Application Forms after becoming a member.

The company applying for product certification must be a Member ID/Manufacturer code holder.

Company that is not an ECHONET Consortium member cannot obtain product certification, but they can sell the certified products.

About 10 working days from the date when the accredited certification body receives the application form, the accredited certification body will determine and notify you of the conformity or nonconformity of the application documents. Please contact each accredited certification body for details.

In principle, you can apply for certification at any time during the business day of the accredited certification bodies. Please contact each accredited certification body for details.

Please contact each accredited certification body.

Certification application is currently available in Japanese which can be found here. “Certification test specifications” can be obtained from Test Specifications. Please use the latest documents when applying. The detailed procedure for obtaining certification is described in the booklet distributed by the certification body, so please contact the accredited certification body first.

If only the ECHONET Lite specifications is certified, the application document including the test results based on the certification test specifications submitted by the applicant will only be examined in writing by the accredited certification body, and no certification test by the accredited testing organization is required. If you want to obtain AIF certification for a low-voltage or high-voltage smart electric energy meter, you need to carry out the certification test related ECHONET Lite specifications and the ECHONET Lite device at the accredited testing organization.

It is possible. However, the Member ID/Manufacturer code installed in the product must be the Member ID/Manufacturer code owned by the applicant..

Though we recommend to obtain the certification with the latest version specifications, it is possible to develop and obtain the certification with the old version specifications. However, please use the latest certification test specifications that correspond to the version you wish to obtain.

Since products sold to general consumers are subject to certification, evaluation boards for developers cannot be certified. For details, please refer to “Guide for Applying for ECHONET Lite Standard Conformity Certification (self-certification)” issued by accredited certification bodies.

Software that consists only of software that cannot provide ECHONET Lite functions to users by itself, such as DLLs, plug-ins, libraries, and middleware, is not subject to certification. For details, see “Guide for applying for ECHONET Lite Standard Conformance Certification (self-certification)” issued by accredited certification bodies.

Refers to the scope of “ECHONET Lite middleware” described in the “ECHONET Lite standards ” (mainly Part 2).

Even if it is an OEM product, because the product certification is required to sell certified products, you need to become an ECHONET Consortium member and apply for certification. However, there is no problem that the OEM company will act for the certification application after your company becomes an ECONET Consortium member.


It is a Web API for services on the cloud to operate ECHONET Lite devices and refer the status of them. As a guideline for that, we have prepared two types of documents: “API specifications section” that summarizes the definition guideline of Web API model and mapping guideline from ECHONET Lite specification, and “device specifications section” that summarizes the Device Description for each device.

ECHONET Lite Web API Experiment Cloud is for the purpose of supporting the understanding of the specifications of ECHONET Lite Web API guidelines and verifying the operation of each Web API. You can use various Web APIs to check the operation of device operations (list acquisition, device SET / GET, etc.) requests and responses.

We currently offer two types of tools that support the ECHONET Lite Web API. Both are client-side software. They are the learning support application “ELWebAPIStudy” for beginners aiming at intuitive understanding of the API specifications, and the operation verification GUI tool “ELWebAPITool” for developers who can check the transmission and reception of detailed commands based on the API specifications.


There is no such thing, but by using a device that supports ECHONET Lite standard, you will be able to receive services such as energy saving and cooperation with various IoT home appliances.

ECHONET Consortium envisions a small range of possible extensions to the home and does not cover large building systems or building management systems.

Each company has released a system that controls ECHONET Lite-compatible devices by linking ECHONET Lite-compatible controllers and AI speakers such as Amazon and Google.


Society 5.0 is a human-centered society that achieves both economic development and solution of social issues through a system that highly integrates cyberspace (virtual space) and physical space (real space). ECHONET 2.0 will realize Society 5.0 by making it possible to operate home appliances and housing equipment in physical space on the Web, which is a cyber space, and by expanding cooperation with services on the Web.

ECHONET Lite and AIF will be treated as technologies that support the service platform for the ultra-smart society on the cloud in ECHONET 2.0 and will continue to be expanded by increasing the number of target devices.

With ECHONET 2.0, IoT life services will also be provided from the Web, more convenient and comfortable life is realized.

For example, a service that allows a certified care worker to grasp the health condition and living environment of a person who need a care with one single application before visiting. It can reduce his/her work burden and a person who need care will be able to live with peace of mind too.


Home control systems such as energy saving and home appliance control, home care, health management services, security services, etc.

ECHONET Lite is used in IoT devices to realize energy saving, convenient and comfortable life, such as control of air conditioners and water heaters, management of solar power generators, and health services.

ECHONET Lite is used in monitoring and control of air conditioners and lighting equipment, security equipment monitoring, and store showcase monitoring systems.

Currently, it is premised on operation by HEMS controller, but ECHONET Consortium is also starting to consider a system that does not use HEMS controller. From a ECHONET Lite-compatible HEMS controller, you can control ECHONET Lite devices and refer to their status. The service is not limited to the energy management system (HEMS), but is expected to be used in comfortable life support services, remote maintenance services, home healthcare services, etc.


Air conditioners, home controllers, water heaters, solar power generators, storage batteries, electric vehicle chargers and dischargers, etc. For details, see Products.

Eight devices that JSCA determined to ensure interoperability with HEMS in 2013, which are Smart meter (B route), solar power generator, storage battery, fuel cell, Charger / Discharger for Electric Vehicles, air conditioner, lighting equipment, and water heater. It is recommended to use ECHONET Lite as a publicity available standard interface between them.

There is no permanent exhibition like a model house. As ECHONET Consortium is introducing what can be achieved with ECHONET Lite at ECHONET Consortium symposiums and various exhibitions, please come and join us.

Anyone who is a corporation and can carry out activities in line with the activities of ECHONET Consortium can participate.

ECHONET Consortium is working to increase the number of device types that define the details of device control commands to 200, and to increase service examples by ECHONET Lite Web API to 50 cases in 2030. For details, see “Roadmap for promoting popularization.”
