Month: 2026-02 Overview: - Focused on delivering a key feature in cdce8p/ha-core and improving the accuracy of history statistics. - This period centered on implementing a configurable minimum state duration for the history statistics component, which filters out short-lived state changes to improve data quality and business insight. Key outcomes: - Implemented History Statistics: Minimum State Duration Configuration in cdce8p/ha-core, enabling a configurable minimum duration for which a state must be maintained to be counted in history statistics. Commit: 9eff12605cfb8c4c346fdb8a30fe0109784abc70 (#151643). - Updated configuration, data handling, and added tests to validate the new behavior and prevent regressions. - Improved historical data accuracy, leading to more reliable analytics and better decision support for product and operations teams. Impact: - Business value: reduces noise in historical statistics by excluding transient states, improving trust in dashboards and historical reports. - Technical: introduced a parameterized configuration path; enhanced test coverage; prepared ground for future refinements in history analytics. Technologies/skills demonstrated: - Python/Backend development, configuration-driven feature design - Test-driven development and test coverage improvements - Data handling and validation improvements - Commit-driven development and code review discipline
