GB/T 46456 "Interconnection of Information Technology Devices and Interoperability of Smart Homes" specifies the architecture and general requirements for smart home interconnection. This document covers topics such as data classification and description, testing and evaluation methods, aiming to provide a framework for information equipment between different brands and between different product categories within the same brand. This will provide a basis and guidance for the interconnection and interoperability of home products such as communication equipment, household and similar appliances, audio and video equipment, and security equipment. It consists of seven parts.

1.Architecture and General Requirements. The aim is to provide the architecture for smart home interconnectivity, as well as the implementation devices and control systems. The general requirements for interconnection and interoperability of equipment, gateways, service platforms, etc.

2.Test Methodology. The aim is to provide execution devices, control devices, gateways, and service platforms that conform to the requirements of Part 1. Methods for testing and verifying interoperability functions.

3.General Requirements for Local Area Networking. The purpose is to provide the functional requirements and message parameter requirements for implementing local area network interconnection.

4.Local Area Network (LAN) Interconnection Testing Methods. The purpose is to provide testing and verification methods for LANs that meet the requirements of Part 3.

5.Classification and Description of Sensing Data. The aim is to provide data for classifying and describing the home environment and family needs to support smart home interconnectivity. Classification and description methods of smart home sensing data, including user data and data on non-device items.

6.System Intelligence Hierarchy. The aim is to provide principles for the intelligence hierarchy of interconnected smart home systems. And the basis.

7.General Requirements for Scenarios. The purpose is to provide the components, classifications, and descriptions of scenarios that support smart home interconnectivity. Requirements, etc. Interconnection of information technology devices and smart home interconnection Part

1 Scope

GB/T 46456.1-2025 is the Chinese national standard covering the architecture the smart home series rests on - the roles of device, controller and gateway, the layers from transport to application, the device model and the interoperability requirements, and the security and privacy baseline. Part 1 of the series, and the parent of Part 3. First edition, in force from 1 February 2026. Issued on 5 October 2025, it has been in force since 1 February 2026.

This document describes the smart home interconnectivity architecture and specifies the execution devices and control devices used to achieve smart home interconnectivity. General requirements for backup devices, gateways, and service platforms. This document applies to the design, research and development, and application of smart home interconnectivity.
