Explore how to construct ReAct AI agents that autonomously interact with Internet of Things environments through this 25-minute conference talk from RIOT Summit 2025. Learn about the implementation of AI agents using a HATEOAS-like approach over CoAP protocol, enabling direct device discovery and interaction at runtime without requiring middleware dependencies like MCP. Discover how these agents can consume real-time contextual information, execute tasks, and communicate with external services across different protocols to fulfill user intents. Examine the current state of AI agent protocols including A2A and MCP, and their potential for exposing services to complex systems through LLM-driven interactions. Gain insights into potential standardization opportunities in the AI-IoT integration domain from Ericsson Research's perspective on combining large language model-powered agents with complex IoT systems.
