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 meet 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 46456.2-2025 is the Chinese national standard covering testing whether two smart home devices really interoperate - the test environment and the reference implementation, the discovery, pairing and control cases, the negative cases and the recovery, and the conformance report.
