Apr 1, 2025April 2025 (2025-04) performance snapshot for OSGP/open-smart-grid-platform. Focused on improving data validation fidelity in the DLMS protocol simulator and ensuring stability of the validation path. Delivered a targeted bug fix that narrows the DATA_NOT_VALID status to the first profile entry, improving data accuracy and reporting reliability for testing and QA. This work reduces false positives in data validation and enhances trust in simulated DLMS interactions, while preserving backward compatibility. The changes are localized to the validation logic and establish groundwork for additional validations.

Nov 1, 2024Delivered critical outage-data and load-profile configuration improvements for the Open Smart Grid Platform (Nov 2024). Implemented Power Outage data management and Get Outages feature, including DLMS object types for power failure event logging and duration, dynamic address resolution for outage retrieval, and extended testing across protocol versions. Updated object counts and data grouping to handle long power failures. Refactored ConfigureDefinableLoadProfileCommandExecutor to use object configuration services, ensuring clock time is captured as the first object, with comprehensive unit and cucumber tests across supported protocols. Expanded test coverage and hardening across both features to improve reliability and maintainability.
