Maximilian Hauser contributed to the evcc-io/evcc repository by developing and refining backend features for hardware integration and energy management. He delivered a template-based integration for the Weishaupt WPM SG Ready Charger, enabling dynamic SG Ready state detection through direct Modbus protocol reads and YAML configuration. Maximilian also addressed compatibility issues for Kostal Plenticore grid charging on older hardware, clarifying template naming to reduce misconfiguration. Additionally, he resolved a bug affecting loadpoint charge voltage publication during phase switching, improving data reliability for monitoring. His work demonstrated depth in Go, embedded systems, and configuration management, focusing on robust, maintainable solutions.
