Bridging Xiaomi VelaOS, vivo BlueOS, Matter, Samsung SmartThings, Home Assistant & OpenHarmony/Oniro/HarmonyOS Ecosystems
1. Executive Summary
This proposal outlines a standardized Proximity Discovery & Interoperability Layer enabling seamless cross-platform device discovery, secure pairing, and ecosystem bridging between major IoT platforms. By creating a common abstraction layer, we can overcome current fragmentation while maintaining ecosystem-specific value propositions.
2. Vision
A world where IoT devices automatically discover and securely connect across ecosystems using native OpenHarmony proximity protocols as the foundational discovery layer, with translation bridges to major ecosystems.
3. Core Architecture
3.1 Unified Proximity Discovery Protocol (UPDP)
Base Layer: OpenHarmony's Distributed Device Discovery (DDD) protocol
Extension: Vendor-neutral proximity detection using BLE 5.3, UWB, and Wi-Fi Aware
Security: Multi-layered authentication (QR, NFC, ultrasonic, biometric)
3.2 Modular Bridge Architecture
