During August 2025, Florian Zahn enhanced the evcc-io/evcc repository by developing two configuration management features focused on energy measurement and meter integration. He consolidated Zewotherm charger E-Meter measurement into a streamlined Energy Input mode, removing obsolete options and ensuring backward compatibility for legacy setups. Additionally, Florian introduced support for the Fronius Verto Plus meter, creating a new YAML-based template that leverages SunSpec models to configure grid, PV, and battery readings with advanced charge and battery control logic. His work demonstrated depth in embedded systems and hardware integration, improving reliability and efficiency for diverse energy metering deployments.
