Developed and integrated Dadapower Charger Voltage Monitoring for the evcc-io/evcc repository, enabling real-time voltage readings from Dadapower chargers to support device health monitoring and usage analytics. Focused on backend development using Go, the work centered on expanding the telemetry pipeline to stream voltage data for dashboards and proactive maintenance alerts. The implementation followed a clear feature-branch workflow with descriptive commits and explicit scope, aligning technical enhancements with business goals around reliability and energy management insights. No major bugs were addressed during this period, as efforts were dedicated to robust API development and seamless telemetry integration within the existing system.
