Xiaomi and Peking University Release IoT Thing Model White Paper, Opening Experience from 1.16 Billion Devices

As smart home devices keep growing in number, the lack of a unified data standard across different device types has long been a challenge for cross-brand and cross-category collaboration.

At the 2026 CCF China Software Conference, the IoT Device Model (Thing Model) Technical White Paper, led by CCF's Ubiquitous Operating System Open Community and jointly written by Xiaomi and Peking University, was officially released. Xiaomi President Lu Weibing announced that technologies verified on 1.16 billion devices will be opened to the whole industry.

Based on Xiaomi's practice with over 1.16 billion AIoT devices across 200+ categories and 10,000+ partners, the paper proposes a four-layer model architecture and a dynamic service mechanism that lets devices auto-discover new functions. It also turns the model into a "capability contract" for AI agents, supporting interfaces like MCP and Function Calling so AI can control devices with natural language, backed by a five-layer security system built on MiTEE.
