Worked on the evcc-io/evcc repository to enhance data retrieval efficiency for Deye Hybrid Meter Registers, specifically targeting multi-register reads in 3-phase configurations. Focused on configuration management and data handling, the developer implemented efficient block reads using YAML to streamline the process of collecting and organizing meter data. This approach reduced per-read overhead and improved the reliability of real-time monitoring and analytics for users of Deye hybrid meters. The work demonstrated a practical application of embedded systems knowledge, addressing the need for scalable and organized data flows in energy monitoring solutions without introducing new bugs during the development period.
