IEC 63510-1:2025

Overview - IEC 63510-1:2025 (Household appliances network and grid connectivity)

IEC 63510-1:2025 is the first part of the IEC 63510 series and specifies general requirements, generic data modelling and neutral messages for interoperable connected household appliances. Published in 2025 (Edition 1.0), this international standard defines how Smart Appliances exchange information with home and building management systems, with a focus on energy management and grid connectivity. The data models are derived by decomposing real use cases into functional blocks implemented by abstract actions on the data model.

Key topics and technical requirements

• Generic data modelling: Canonical object and attribute models for connected household appliances to enable consistent information exchange.
• Neutral messages: Message types and semantics designed to be transport- and protocol-agnostic so different network stacks can interoperate.
• Interoperability process and architecture: Requirements and recommended processes to enable device-to-system interoperability (architecture, reader’s guide, flowcharts, sequence diagrams).
• Use cases and user stories: Detailed user stories and use cases (e.g., flexible start, incentive-table based power management, monitoring, manual operation) used to derive data models.
• Use Case Functions (UCFs): Defined function blocks such as measurement, device configuration, heartbeat, plan and power sequence management, power limit and reporting functions.
• Energy management features: Support for appliance energy flexibility, limiting consumption (including self-consumption optimization), reporting of power consumption and flexible scheduling.
• Requirements for implementation: Scenario support requirements, dependencies, assumptions/prerequisites and detailed UCF descriptions to guide implementers and testing.

Applications and who uses this standard

IEC 63510-1:2025 is targeted at stakeholders building interoperable smart-appliance ecosystems:

• Appliance manufacturers implementing standardized data models and neutral messages for smart white goods, heat pumps and other household devices.
• Home/building energy management system vendors and integrators designing control, monitoring and demand-response features.
• Utility and grid operators seeking standard interfaces for appliance-level demand flexibility and grid services.
• Software developers and API designers creating protocol bindings or message brokers that map neutral messages to transports (MQTT, CoAP, HTTP, etc.).
• Certification bodies and test labs validating interoperability and conformance to the IEC 63510 series.

Related standards

• Part of the IEC 63510 series - other parts specify bindings, protocol mappings and device-specific adaptations to complement the generic models and neutral messages.
• Relevant to standards and initiatives in home energy management, smart grid and IoT interoperability.
