Developed and delivered the EcoFlow PowerOcean meter integration for the evcc-io/evcc repository, enabling users to monitor grid, photovoltaic, and battery energy usage from EcoFlow devices. The work focused on backend development and API integration using Go, with careful attention to secure configuration and credential validation to ensure authorized data access. Implemented robust data retrieval methods and comprehensive error handling to improve the reliability and resilience of telemetry streams. This feature expanded device compatibility and provided users with enhanced visibility into their energy flows, supporting more informed energy management decisions and contributing to the overall extensibility of the evcc platform.
