WG 1 - ISO/IEC JTC 1/SC 25/WG 1

ISO/IEC 18012-4:2025 specifies an event exchange format that defines the encoding of individual events in the interoperability domain. This event format is used to encode events for exchange across the “event bus” within the interoperability domain.

ISO/IEC 18012-3:2025 specifies a lexicon of objects for the interoperability domain (ID). This document specifies ID base objects and their associated properties and input/output event types (i.e. in the form of a list of ID sensor, actuator, and control objects), and object state actions, which can be used to define interoperable application models.

ISO/IEC 15045-4-1:2024 specifies a set of physical classes for the HES gateway system. It also specifies the requirements of HES gateway modules including home area network interface modules, wide area network interface modules, binding map service and service modules for any class chosen.

ISO/IEC 15045-4-2:2024 specifies the simple HES gateway, which is one of a set of physical classes introduced in ISO/IEC 15045-1:2004

ISO/IEC 15045-3-1:2024 describes the series of privacy, security, and safety standards to support the HES Gateway and attached devices. The purpose is to specify methods for protecting home and building systems from both internal and external threats, intrusions, or unintended observation of data and unsafe conditions that could result from network functions. Part 3 defines a set of basic and advanced requirements for gateway monitoring and control of both inbound and outbound traffic, including switching/routing, addressing, encryption, intrusion detection and prevention, and other “firewall” functions.
The Part 3 requirements specify the following functions:
1) prevention of active inbound attacks and unsafe commands,
2) discovery and classification of outbound traffic,
3) interoperability of premises internal network traffic,
4) management of privacy and security mechanisms, and
5) provision for a management and reporting dashboard for use by the non-technical end-user.
This standard describes the inter-relationships between privacy, security, and safety.

ISO/IEC 15045-3-2:2024 specifies cybersecurity requirements for protecting the privacy of premises and personally identifiable information through the use of the HES gateway and related HES standards. This document applies a set of principles including those specified in ISO/IEC 29100 that are applicable to the HES gateway such as consent, purpose legitimacy, collection limitation, data minimization, retention, accuracy, openness, and individual access.

ISO/IEC 15067-3:2024 focuses on a model of a system in homes and buildings that can manage energy consumption and generation of electricity by devices on premises dynamically in response to electricity availability from:
– sources within the home or building such as solar panels, wind turbines, or storage (stationary or mobile),
– neighbourhood microgrids,
– transactive energy,
– energy aggregators, and
– public utilities.
This document specifies a model including a framework and methods for energy management consisting of interconnected elements that can be configured to support various methods for a Home Electronic System (HES) energy management system. The methods specified are intended to be generic and representative of a wide range of situations. This document applies to the customer grid-edge portion of the electricity grid (within a home or building) and applies even if the consumer has sufficient local power generation to operate without connecting to a public utility.
This document includes an energy management model that balances power supplied from internal and external sources with demand from appliances and electric vehicle chargers. The model offers flexibility for locating the energy management equipment in a stand-alone product, embedded in consumer electronics, or hosted in a gateway. This gateway can be a generic communications interface between a home network and an external network, an energy management gateway designed for handling energy-related data, or the HES gateway specified in the ISO/IEC 15045 series.
This model specifies a local controller that achieves the allocation of power in accordance with available supplies, consumer preferences for appliance operation, and power requirements of these appliances within constraints set by the consumer. Such constraints are typically financial (a budget for electricity) but can also include goals such as using green sources and minimizing their impact on climate change. This controller is called the energy management agent (EMA) since it acts as an agent for the consumer. This model accommodates an EMA with technology of artificial intelligence to facilitate energy management.
This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) This edition revises ISO/IEC 15067-3:2012 by expanding beyond demand response to include a balance between multiple sources of power and appliance demands for this power.
b) This edition specifies a system framework that addresses the need for user-centric energy management by providing control options for consumers.

ISO/IEC 10192-4-2:2024 specifies a control architecture, user interface, and service objects in the HES gateway to enable interworking among home cluster systems and interoperability among the applications supported by these cluster systems. The ISO/IEC 10192 series specifies a common user interface to these cluster-system applications. This common user interface provides input and output methods for user information exchange to access, monitor, control and coordinate applications running on home cluster systems.
This document specifies the application object, service and interface modules from the interoperability standard (ISO/IEC 18012 series) necessary for interworking and incorporation of these modules in the HES gateway (ISO/IEC 15045 series).

ISO/IEC 15067-3-51:2024 specifies a Narrow AI Engine Framework including requirements for the Energy Management Agent (EMA) specified in ISO/IEC 15067-3. This standard includes specifications for an AI infrastructure to be embedded in an EMA serving a single structure (home or building) or community housing such as an apartment complex. The Narrow AI Engine specified in this standard for EMAs enables demand response functionality to be located in each EMA instead of an external energy management system. Thus, energy management can be adapted to local and customer needs. The Narrow AI Engine includes operational principles such as prediction, decision–making, and control.
This standard builds upon the EMA functions of ISO/IEC 15067-3 and ISO/IEC 15067-3-3. The AI functions specified in this standard support complex decisions about energy management for devices attached to home and buildings networks. These AI specifications enable the EMA to allocate power from public sources (including conventional and nonconventional sources) and local sources (wind, solar, and storage) according to price, availability, appliance and electric vehicle demands, customer preferences, and the customer’s budget.

ISO/IEC 15067-3-31:2024 specifies a protocol for energy management agents (EMAs) to facilitate communications among these agents for demand response (DR) energy management applications. The EMA protocol (EMAP) provides a logical connection among EMAs in community housing such as an apartment building or a campus of houses or apartment buildings. This document also specifies interaction procedures and message formats for DR energy management as introduced in ISO/IEC 15067-3-3. The EMAP supports interactions among EMAs at OSI (Open System Interconnection) layer 7 with a message transfer protocol. An EMA can be embedded in devices such as a thermostat, a smart appliance, or other consumer products. The choice of interconnection depends on the system and the network topology, which can be arranged in a mesh or hierarchical tree structure. An intermediate EMA may relay messages sent between EMAs.

ISO/IEC 15067-3-30:2024 specifies functional requirements and reference interfaces for interconnected energy management agents (EMAs) based on the model for an EMA specified in ISO/IEC 15067-3 and the model for multiple interacting EMAs specified in ISO/IEC 15067-3-3. This specification supports energy management by facilitating interactions and information exchange among EMAs and appliances, consumer electronics, heating, ventilation, and air conditioning (HVAC) equipment, water heaters, distributed energy resources (DERs), electric vehicle (EV) chargers, and other loads supplied by public and local power sources in a house or an apartment complex. Local power sources can use DER, which can include, but are not limited to, wind turbines, solar panels, and storage (stationary and mobile). EMAs specified with these functions and interfaces can assist the consumer in responding to price-varying public power and buying or selling transactive energy (TE).
This document specifies framework methods for EMAs to co-ordinate the delivery of energy management applications, and the reference interfaces facilitate a communications protocol among interacting EMAs. These linked and interacting EMAs provide energy optimization and conservation within constraints such as a consumer's financial budget and goals for greenhouse gas reduction, while supporting programmes as diverse as TE and demand response (DR).

ISO/IEC 14543-5-194:2024(E) specifies the remote access (RA) server-based application framework, device interaction model, flow process and interfaces, and message formats to achieve intelligent grouping, resource sharing and service collaboration among IGRS smart lock devices.
This document is applicable to smart lock devices with direct network connections or connections through an intermediary network to a server for security authentication. This server utilizes a method to minimize the possibility of unauthorized access to these smart locks, while maintaining seamless interoperability among users, smart lock devices and RA servers at home, office or other remote environments.

Networked audio devices can include a multi-room home audio system, a high-fidelity audio system, a home theatre, a smart radio, background audio, mobile audio and public audio equipment. Services specified by this document enable smart audio interconnection applications to interoperate seamlessly among audio devices and resource servers at home, in an office or in other remote environments. These services can include multi-device synchronization, sound configuration, audio on-demand service and music streaming and rendering.

ISO/IEC 14543-4-302:2023 specifies an application-layer protocol important for ensuring interoperability among the products of various manufacturers regarding communications between electrical storage systems and controllers. It uses the network enhanced communications device (NECD) protocol specified in ISO/IEC 14543-4-3. This protocol is based on UDP using IPv4 or IPv6 (TCP is optional).

ISO/IEC 10192-4-1:2022 specifies an architecture for home cluster systems and for interworking among them. It specifies a cluster-to-cluster interface to enable interworking among home cluster systems and interoperability among the applications supported by these cluster systems as well as a common user interface to these cluster-system applications. This common user interface provides input and output methods for user information exchange to access, monitor and control applications running on home cluster systems.

ISO/IEC TR 15067-3-7:2020 (E), which is a Technical Report, explains the organization and structure of the transactive energy systems research, development, and deployment roadmap.

ISO/IEC 14543-4-301:2020 specifies an application-layer protocol necessary for ensuring interoperability among the products of various manufacturers regarding communications between home air conditioners and controllers, using a protocol called network enhanced communications device (NECD) as specified in ISO/IEC 14543-4-3. This protocol is based on user datagram protocol (UDP) using IPv4 or IPv6 (TCP is optional).

ISO/IEC 14543-3-10:2020(E) specifies a wireless protocol for low-powered devices such as energy harvesting devices in a home environment. This wireless protocol is specifically designed to keep the energy consumption of such sensors and switches extremely low. The design is characterized by • keeping the communications very short, infrequent and mostly unidirectional, and • using communication frequencies that provide a good range even at low transmit power and avoid collisions from disturbers. This allows the use of small and low-cost energy harvesting devices that can compete with similar battery-powered devices. The messages sent by energy harvesting devices are received and processed mainly by line-powered devices such as relay switch actuators, repeaters or gateways. Together these form part of a home automation system, which, when conforming to ISO/IEC 14543 (all parts), is defined as a home electronic system. This document specifies OSI Layers 1 to 3 of the amplitude modulated wireless short-packet (AMWSP) protocols. The AMWSP protocol system consists of two and optionally three types of components that are specified in this document. These are the transmitter, the receiver and optionally the repeater. Repeaters are needed when the transmitter and the receiver are located in such a way that no good direct communication between them can be established. Protection against malicious attacks is handled in the upper layers and thus not treated in this document.

ISO/IEC 14543-5-102:2020(E) specifies the system architecture and communication protocols of remote universal management profile to achieve intelligent grouping, resource sharing and service collaboration among different devices and controllers. The protocol features are: a) remote universal device discovery and management framework that includes connection methods and network architecture, device configuration interfaces, management message formats and message exchange flows; b) request/response message formats for four remote universal management profile device types: water heater, refrigerator, air conditioner, microwave. This document is applicable to remote access of water heaters, refrigerators, air conditioners, microwave ovens at home, office or other remote environments, to achieve universal management and interactions among these controllers and devices

ISO/IEC 15067-3-3:2019(E) specifies a high-level architecture and a set of models for a demand-response energy management system with multiple interacting EMAs in a home or community housing (such as one or more apartment buildings or a campus of houses). These models specify the structure among multiple EMAs, which can be arranged in a mesh or hierarchical structure. This document builds upon ISO/IEC 15067-3.

ISO/IEC 14543-5-101:2019 (E) enables a media connection, resource sharing and co-operation among computers, home appliances and consumer electronics using remote access (RA). Also, users and devices can share and control media resources. This document specifies: • an IGRS remote media access profile based on the IGRS RA core protocol and the IGRS RA platform protocol, and • application rules for the interoperation between IGRS RA media users and devices

ISO/IEC 14543-5-12:2019(E) specifies the test and verification methods for an intelligent grouping and resource sharing (IGRS) remote access (RA) user or device, defines the structure of a user and device testing system for IGRS remote access, describes and specifies the exchange process between a user or device-under-test with a standard IGRS RA service platform (IRSP), and describes and specifies the rules to have validating messages. This document is applicable to the test and verification of an IGRS RA device or user.

This document specifies the mechanical, electrical and logical characteristics of the interfaces of UCM to an end device and a choice of interfaces to a home communications network.

ISO/IEC 15045-2:2012(E) specifies a gateway architecture that provides an interconnection between one or more Wide Area Networks (WANs) and one or more Home Area Networks (HANs). It is not needed for a "simple gateway" linking one WAN to one HAN where there is no intention of future expansion. It applies to a "distributed gateway," and is also referred to in ISO/IEC 15045-1 as the Complex Modular Gateway. Also, it specifies how separate gateways in a single house can interoperate to provide co-ordinated functions.

ISO/IEC 15067-3:2012(E) specifies an energy management model for programs that manage the consumer demand for electricity using a method known as "demand response". Three types of demand response are specified in this standard: direct control, local control and distributed control. It replaces ISO/IEC TR 15067-3, first edition, published in 2000, and constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition: - the demand response options have been expanded; - distributed energy resources such as local generation and storage have been included; - the terminology for demand response has been aligned with smart grid.
