FIWARE IoT agent for Matter: Toward the integration of smart home devices into the FIWARE smart city platform

The rapid adoption of the Matter protocol as a global standard for smart home appliances presents a significant opportunity to enhance the interoperability of IoT devices. Concurrently, FIWARE, a widely adopted smart city platform, facilitates seamless integration and management of diverse IoT devices through standardized data models and context management capabilities. However, integrating Matter-enabled devices with FIWARE remains a challenge due to differences in protocol architectures and data representations. This paper proposes a novel framework to bridge the Matter protocol and the FIWARE platform, enabling interworking between smart home appliances and smart city services. The proposed solution includes: (1) a data model and adaptive translation algorithm for mapping Matter device specifications to FIWARE Smart Data Models, (2) an IoT Agent to interface Matter devices with the FIWARE platform as FIWARE resources, and (3) a comprehensive evaluation using commercial and experimental Matter-enabled devices. This approach ensures seamless data exchange, enhances cross-domain interoperability, and supports the integration of Matter devices into smart city contexts. The results demonstrate the feasibility and efficiency of the integration, offering a scalable framework for leveraging low-cost Matter devices as assets within smart city platforms. This work contributes to advancing IoT interoperability and paves the way for innovative applications in smart homes and smart cities. • This work represents the first implementation of a FIWARE IoT Agent for Matter, a new smart home protocol gaining worldwide attention in the context of the smart city platform FIWARE. • This work introduces a comprehensive FIWARE Smart Data Model for Matter based on the Matter specification (version 1.4), enabling smart city services to interact with Matter devices exclusively through FIWARE. • This work enables sophisticated smart city services to leverage low-cost smart home devices.
