Monthly summary — 2025-08: Focused on stability and correctness of Shelly binding in openhab-addons. Key accomplishments include a targeted bug fix where the deviceType parameter now correctly takes precedence when determining the Thing UID in the Shelly binding, improving binding accuracy and end-user experience. I also simplified tests by removing an unnecessary deviceType parameter and added a dedicated test (getThingUIDDeviceTypeTakesPrecedence) to verify the correct behavior. These changes were implemented in commit fa5ee6a6ba658ee68afc6bd1cb76af3224ed54cd, reflecting Java/JUnit-based testing discipline and improved CI reliability. Overall impact: reduced misbindings, clearer test coverage, and easier maintenance for Shelly binding in openhab-addons.

July 2025: Delivered major enhancements across openhab-addons, openhab-core, and openhab-distro focused on reliable device discovery, modernized APIs, and expanded device support. Key outcomes include Shelly discovery refactors and fixes, including thing type handling improvements, Pro 2 relay discovery fix, mDNS robustness, BLU name decoupling, and decoupling thing type IDs and service names; migration of discovery timestamps to Instant-based APIs with removal of deprecated listeners; addition of Shelly Plus device support; API cleanup removing deprecated DiscoveryListener usage; improvements in error diagnostics and test coverage; stability and maintenance upgrades such as BlueZ 0.3.2 and related improvements; and a breaking notice for Tibber binding to inform downstream integrations. These changes reduce runtime errors, improve discovery latency, enable safer migration paths, and broaden device compatibility, delivering tangible business value for customers migrating to Instant-based discovery and Shelly ecosystem expansions.
