Josef: A Java-Based Open-Source Smart Meter Gateway Experimentation Framework

Smart meter gateways are the core component of the advanced metering infrastructure in Germany, and provide a unified interface for metering data retrieval to third parties. Different standards and communication protocols exist for smart metering, ranging from transmission protocols to architectural recommendations. This work briefly presents the concept of the German BSI TR-03109 smart metering architecture, reviews implementations of smart metering protocols and architectures, and provides a Java-based open-source smart meter gateway experimentation framework (jOSEF). The proposed framework combines and extends established protocol frameworks to provide a flexible tool for the validation of smart metering communication use cases involving smart meter gateways.
