PROFILE
Ante Karamatić
Ante Karamatić contributed to the evcc-io/evcc repository by developing and enhancing integrations for energy monitoring and electric vehicle systems. He implemented robust data parsing and fallback logic for Enphase PV production, ensuring reliable monitoring even with sparse or missing CT meter data. Ante also improved multiphase current readings and expanded SolarEdge PV meter support by updating YAML templates for accurate current measurement retrieval. Additionally, he enhanced Home Assistant integration by mapping Porsche EV charging states to API statuses, increasing reporting accuracy. His work demonstrated depth in Go, YAML, and embedded systems, focusing on data integrity and compatibility across diverse hardware.

Jan 1, 2025January 2025: Delivered two high-impact items for evcc-io/evcc that improve data reliability and meter coverage. 1) Enphase Multiphase Current Readings Robustness—prevented errors when fewer than three phases are present by validating the 'lines' array before access, stabilizing net consumption/production data retrieval. Commit: 4acb4ccfcae50d326b927740e567003d95b76ba2. 2) SolarEdge PV Meter Current Measurements—added support to read AphA, AphB, AphC by updating the solaredge-inverter.yaml template to enable querying and processing these values. Commit: 81701912f833398c32b694b28e322c06fec5b7d5. These changes enhance data reliability, expand device compatibility, and enable more accurate energy analytics for customers.

Dec 1, 2024December 2024 monthly summary for evcc-io/evcc: Delivered Enphase integration enhancements focused on data reliability and signal resilience. Implemented CT data source support for PV production and robust handling when CT meters are absent, along with improved parsing and fallback for sparse production data via production.json to preserve monitoring accuracy. These changes reduce data gaps, increase uptime, and enable smoother operation for customers with variable data quality.
