Representative Director
Katsuhiko Hiramatsu, Panasonic Corporation
ECHONET Consortium was established in 1997 with the aim of creating an abundant 21st century
society where people and the environment live in harmony. ECHONET Consortium will celebrate its
27th anniversary in December 2024, thanks to your dedicated efforts and cooperation.
The ECHONET Consortium is advancing the establishment of standard specifications forfoundational technologies such as interconnected home networks and networks for small andmedium-sized buildings and stores, to address environmental issues, energy challenges,
decarbonization, and aging societies through the interoperability of various vendors' home
appliances, facility equipment, sensors, controllers, and more.
The "ECHONET Lite specifications" announced in 2011, recognized as a standard protocol
domestically and internationally, was recommended as a well-known standard interface for HEMS
(Home Energy Management Systems) at the "Smart Community Alliance International
Standardization WG Smart House Standardization Study Group" the following year, and wasapproved as an international standard in 2015. Subsequently, in pursuit of improved interoperability
among multi-vendors, the "ECHONET Lite AIF specifications" was formulated, and a certification
system was initiated in 2016. Thanks to the efforts of our members, the number of shipments of
ECHONET Lite devices has reached almost 150 million units as of the end of the 2023 fiscal yearwith 120 device models, and the coverage continues to expand.
In recent years, we have been confronted with numerous significant challenges such as "global
conflicts and associated economic/energy security," "global warming," "increasing frequency ofsevere disasters," and "aging populations." To address these challenges, many concepts such as the"The Vision for a Digital Garden City Nation," "Realization of a decarbonized society," and "IENAKA
data linkage platform" are being considered and proposed.
In response to these concepts, the ECHONET Consortium believes that by providing a "Orderly
collaborative creation space" where residential facilities and commercial equipment can be safely
controlled and data can be utilized, we can contribute to the creation of new services that help solve
social issues.
Specifically, the ECHONET Consortium will promote the development of technologies to realize
the " Orderly collaborative creation space" by further enhancing and promoting the spread of the"ECHONET Lite specifications" and "ECHONET Lite AIF specifications" for multi-vendor
interoperability in residential/business spaces, and by implementing further functional expansion of
the ECHONET Lite Web API Guidelines in the internet space. Furthermore, we will expand ouractivities, focusing on the utilization of next-generation smart meters and DR-ready support, toachieve the realization of a decarbonized society and ensure further development.
We kindly ask for your support and cooperation in these endeavors.

surrounding smart home
After reaching a peak in FY2004, the energy consumption in Japan has been on a downward
trend. This is due to economic growth while curbing energy consumption as Japanese energy
consumption moves towards energy saving, particularly in the industry sector, and the developmentof energy saving products has become popular.
However, when looking at trends by sector for growth between FY1973 (at the time of the oil
embargo) and FY2022, while the commercial and business sector remained at 0.9 times with theprogress in energy saving mainly in the manufacturing industry, because of the 1.8 times increase inenergy consumption in the household sector.
In response to the tight power supply and instability of energy prices, there is a renewed sense of
the importance of energy conservation in the household sector and it is essential to improve theenergy conservation of houses themselves.

(To be replaced with English version when available)

On the other hand, thanks to a policy established to promote the introduction of solar power
generation, it has increased by an average of approximately 64 MW a month since 2013 and isforecast to reach approximately 140 GW by 2030. The result of this may cause that the generated
power has exceeded demand from business offices and homes is flowing into the power distribution
system and as this has caused a rise in voltage in the power distribution system, it has the potential
to interrupt the high quality and stable provision of power. In order to prevent this, in addition topromoting technical development that would restrain the amount of power generated by solar power
generation, there are calls for promoting the deployment of equipment that can store energy, such as
electric vehicles, storage batteries and heat pump water heaters, thus “creating electricity”, “storing
electricity” and “efficiently using electricity”.
Under these circumstances, Net Zero Energy Houses (ZEH) are attracting wider attention as a
housing solution that minimizes energy consumption in houses and energy independence in cases ofdisaster. A ZEH is “a house that aims to achieve a zero balance of annual primary energy
consumption through the introduction of renewable energies, after drastically improving heatinsulation performance in its outer shell and achieving substantial energy conservation, while
maintaining room environment quality by introducing highly effective equipment systems”. The
increasing spread of ZEH is expected to drastically improve the energy supply and demand structure.
In Japan, the policy target is set to “aiming to achieve ZEH for average new houses by 2030” and the
Sixth Strategic Energy Plan (approved by the Cabinet in October 2021) states the further energysaving measures will be comprehensively promoted for the realization of carbon neutrality by 2050
and the GHG emission reduction by 2030.

Further, because an amendment to the Energy Conservation Act that came into effect on April 1,2014 made it mandatory for all households to install smart meters, all electric power companies havebeen working on installing them with the goal of completing the process by 2025 since July 2015. Of
the three information transmission routes available for smart meters, the ECHONET Lite standards is
adopted for Route B which is communication with HEMS. With this adaptation as a trigger, equipment
which adopts the ECHONET Lite Standards becomes widespread in the home, which makes theelectricity usage status measured by the smart meter can be observed in the home as well.
The cumulative number of ECHONET Lite devices excluding smart meters shipped from FY2013
to FY2023 reached 67.58 million units. On the other hand, the cumulative number of installed smart
meters by FY2022 and planned smart meters to be installed in FY2023 reached 82.28 million units.
Therefore, the total number of ECHONET Lite compliant products by the end of FY2023 reached
149.9 million units.

Cumulative number of shipped or scheduled ECHONET Lite compliant devices
In countries other than Japan, “ECHONET Lite Communication Middleware” and “Detailed
Requirements for ECHONET Device objects”, which both make up a major part of the ECHONET Lite
standards, were approved as international standards as ISO/IEC 14543-4-3 and IEC62394 in 2015.
Since 2016, we have been focusing on promoting ECHONET Lite in Southeast Asian countries,
especially in Taiwan, we have been working to spread the ECHONET Lite and ECHONET Lite Web
API technologies.
In 2020, "Interface Specifications for Application Layer Communication between home air
conditioners and HEMS controllers" was recognized as an international standard as ISO/IEC 145434-301, and in 2023, "Interface Specifications for Application Layer Communication between storage
batteries and HEMS controllers" was recognized as an international standard as ISO/IEC 14543-4302. This means that a process to build an environment to spread HEMS devices in terms of bothusing and storing electricity is underway, and we can expect not only reduced energy consumption
through HEMS, but also the promotion of using various types of energy at home (a combination ofusing renewable energy, stored energy, and energy generation equipment). If the introduction of
HEMS on a global scale progress, we can also expect HEMS related Japanese products such as air
conditioners have a greater advantage, along with an expanded market for service businesses
related to them. We are currently working on proposing that "Interface Specifications for Application
Layer Communication between electric vehicle charger/discharger/electric vehicle charger and HEMS
controllers" become the next international standard.
On the other hand, in the field of information technology, the IoT (Internet of Things) has been
proposed and a new value that leverages the vast amount of interconnected and collected data via
internet has been created. Moreover, in the future society to be realized under Society 5.0 which isadvocated as the ideal form of Japan, social issues are resolved, and new value is brought by linking
all people and things through IoT, sharing a wide variety of knowledge and information, creatingcompletely new value, and creating opportunities to provide the timely and necessary information
when using artificial intelligence (AI).

ECHONET Lite, a publicly-known standard that realizes
smart home
The ECHONET Lite Standards published in 2011 were later recommended as a publicly-known
standard for home networks by the Japan Smart Community Alliance established by the Ministry of
Economy, Trade and Industry (METI). The ECHONET Consortium is working to improve
interoperability among multiple vendors by establishing a certification system and standardizing
detailed ECHONET Lite usage for each device.

ECHONET Lite is a communication specification that enables resource-saving devices (such as
sensors, home appliances, and facility-related equipment) to support IoT and realizes energy
management service and remote maintenance service. By adopting common specifications forcommunication specifications and commands for devices, it is possible to build a system in a multivendor environment. The following figure shows the structure of ECHONET Lite specifications.

The ECHONET Lite standards have become general-purpose specifications that can be applied toall over 120 types of devices thanks to achieve a high level of interoperability by conducting standard
conformity certification tests. The ECHONET Consortium has defined more than ten types of devices
as key devices, including home air conditioners, storage batteries, solar power generation,commercial-use package air conditioners, and smart meters (high/low voltage). In order to achieve ahigher level of interoperability for these devices, the ECHONET Consortium has formulated theInterface Specifications for Application Layer Communication (AIF specifications) which define thespecific usage of ECHONET Lite at the application level of each device. For example, the AIF
specifications defines the following items:● Installed device objects● Combination of supported properties● Timeout after sending a request until receiving a response● Sequence assuming concrete use caseIn addition, by conducting standards conformance certification tests for AIF specifications at athird-party testing laboratory certified by the ECHONET Consortium, we are conducting more reliable
tests.
(4) Enables linkage with cloud services
It is important to study overall system architecture to study communication specifications. When
we formulated the ECHONET Lite communication specifications, we designed an architecture which
set controllers or similar devices which have gateway functions between various internet-based
services and devices installed at local environment such as ordinary homes. The figure below shows
an example system configuration.

ECHONET Lite Web API
As IoT technology evolves, the cloud-based service delivery model is developing. Under thesecircumstances, it is conceivable that the various services and application development that effectively
uses ECHONET Lite devices, which are becoming increasingly popular, will be developed as new
businesses. As a measure to boost the number of service providers that provide those businesses,
the ECHONET Consortium formulated the ECHONET Lite Web API Guidelines which are common
technology for service and application developers.

The ECHONET Lite Web API Guidelines are composed of two types of documents: (1) API
specifications section that summarizes the definition policies of the Web API models and the mapping
policies from ECHONET Lite specifications; and (2) Device specifications section that summarizes
the Device Description for each device.
The API specifications section supports: (1) basic use cases including obtaining device lists andobtaining and controlling device status; and (2) application use cases including grouping multiple
devices and obtaining historical data. In the Device specifications section, specifications are being
developed sequentially, with priority given to (1) AIF devices and (2) ECHONET Lite certified devices.
To conduct operation verification of services compliant with the ECHONET Lite Web API
Guidelines, an Experimental Cloud compliant with the guidelines is provided as a free service
exclusively for ECHONET Consortium members. The Experimental Cloud grants an account to eachapplicant so he/she can freely formulate emulation device configurations that is suitable for theservices to be developed that are assumed by each user.

ECHONET 2.0
The world that ECHONET 2.0 is aiming for
Nowadays, various services are increasing in the virtual space on the cloud, and it has become
the age that is aiming to realize a super smart society by Cyber Physical System (CPS). As theInternet environment and the society change drastically, ECHONET Consortium set up the“ECHONET 2.0 Strategic Guidelines” in February 2022 to contribute to the realization of SDGs and isstrengthening the cooperation with related organizations along with expanding the ECHONET Lite
standards and AIF specifications. ECHONET 2.0 aims to contribute to SDGs by creating a wide
variety of new services through the development of ECHONET Lite based platforms by expanding theway services are linked in the cloud era.
ECHONET 2.0 aims to expand in two directions. The first one is to expand and enrich the
ECHONET Lite standards, which has become popular in homes and lifestyles, to fields other thanhome appliances and housing equipment. The second one is to create and expand new value by
expanding service collaboration on the cloud using ECHONET Lite Web APIs, so that various devices
in the home can be connected to all kinds of services in the evolving digital society.

Contribution to the realization of SDGs
Through the formulation of the ECHONET Lite standards, ECHONET Consortium hasstrengthened the creation of an environment in which the interoperability of resource equipmentgroups can be verified. In the future, in addition to this, we will work to create an environment where
we can certify reliable operators and confirm interconnectable cloud interfaces in cyber space and byrealizing the "Orderly collaborative creation space", aim to build a cooperative relationship between
service providers and equipment manufacturers and contribute to the realization of SDGs.

Certification system
Purpose and Benefit of Certification
By FY2023, 149.8 million ECHONET Lite devices had been shipped to the market.
Various services, including energy-saving and home security services, can be brought to the realworld by combining ECHONET Lite devices to build a home network.
The ECHONET Consortium established a certification system to prove that products are properly
compliant with the ECHONET Lite standard and the AIF specifications so that users can feel
confident in building a home network.

Overview of Certification system
There are two certification systems established by the ECHONET Consortium: (1) ECHONET Lite
Standard Conformance Certification and (2) Application Communication Interface Specification
Conformance Certification System (AIF Specification Certification System).
Under the ECHONET Lite Standard Conformance Certification System, an applicant tests its
device by itself based on the ECHONET Lite device certification test specification documet to confirm
that the device conforms to the ECHONET Lite standards and the Detailed Requirements for
ECHONET Device objects. Then, the applicant submits the test results to an accredited certification
body. The accredited certification body makes a pass or fail judgment of the device based on the test
results and grants an ECHONET Lite Standard Certification Registration Certificate if the application
meets the criteria.
Under the AIF Specification Certification System, an accredited testing organization tests thedevice based on the corresponding AIF Specification Certification test specification document, andafter the accredited certification body confirms that the device has obtained the ECHONET Lite
Standard Conformance Certification, it will make a pass or fail judgment of the device based on thetest results of the accredited certification body and grant an AIF Specification Certification
Registration Certificate if the equipment meets the criteria. If the applicant obtains AIF Specification
Certification for a smart meter, it is necessary to conduct a test to obtain the ECHONET Lite Standard
Conformance Certification at an accredited testing organization.
