April 2026: Tibber integration improvements in home-assistant/core. Upgraded the pyTibber library to 0.37.0 and implemented asynchronous access token handling for Tibber API access. Updated tests to cover the new access token method, ensuring regression protection as APIs evolve. These changes increase reliability of real-time energy data retrieval and reduce token-related failure risk, while paving the way for future Tibber API changes.

Month: 2026-03 — Delivered two critical updates in home-assistant/core, focusing on pricing data handling and energy reporting accuracy. 1) Tibber Price Coordination and Real-time Pricing Updates implemented via TibberPriceCoordinator to manage price data updates, enabling organized retrieval and faster responsiveness to real-time price changes. 2) Energy Unit Standardization: Watt-hours to Kilowatt-hours in Homevolt to fix reporting accuracy across energy metrics. The work included commit-level fixes for Tibber update tokens and energy unit calibration, improving reliability and data integrity.

February 2026 performance: Implemented comprehensive Homevolt integration enhancements and quality improvements across core and branding repos to improve monitoring, control, and reliability for Homevolt devices. Delivered features to monitor battery metrics, diagnostics, discovery, reauthentication, and local-switch control, plus zeroconf discovery and a dedicated switch platform. Added Homevolt support to the Home Assistant brands platform. Upgraded integration quality (Bronze to Silver) and refreshed documentation to reflect capabilities. Also fixed a key handling bug in the Homevolt integration. These efforts enhance device visibility, issue diagnosis speed, and user workflows, delivering measurable business value for Home Assistant users.

January 2026 monthly summary: Delivered security-forward Tibber integration improvements and expanded observability across core and docs. Key efforts include migrating Tibber to OAuth2 with session management and backward-compatible tokens to enable Tibber Data API access, expanding the Tibber sensor suite for improved monitoring, standardizing distance units to meters for accuracy, upgrading the pyTibber client library for compatibility, and improving API rate-limit handling. Also performed code cleanup of initialization/reauth flows and updated documentation for Homevolt and Tibber-related sensors to improve onboarding and troubleshooting. Business value: strengthened security, higher data fidelity, better operational visibility, and reduced maintenance risk for end users and maintainers.

December 2025: Focused integration maintenance on mib1185/homeassistant-core by upgrading the Adax-local library (0.2.0 -> 0.3.0) to gain compatibility, new features, and bug fixes. The work improves device support and stability within Home Assistant and positions the project for upcoming enhancements.

Concise monthly summary for 2025-11: Key contributions across mib1185/homeassistant-core focused on dependency maintenance to ensure long-term compatibility and stability of the Mill Home Assistant integration. Delivered a dependency upgrade to millheater 0.14.1, aligning the integration with the latest mill features and fixes.

October 2025: Focused on stabilizing the core dependency stack in home-assistant/core by upgrading key libraries to the latest releases to improve stability, compatibility, and access fixes. This work reduces risk of regressions and sets the stage for smoother future releases.

Month 2025-09 — Focused on upgrading Tibber-related libraries, dependency updates, and data-structure refinements for Tibber pricing, delivering compatibility, performance, and data integrity improvements for the home-assistant/core integration.

June 2025: Focused reliability improvements in the Tibber integration for the home-assistant/core repository. Upgraded the pyTibber client to version 0.31.6 and strengthened error handling for Tibber connections to enhance stability and user experience. This work improves energy monitoring reliability and reduces user-visible failures.

May 2025: Consolidated maintenance and value delivery in home-assistant/core by upgrading core data libraries to current releases, unlocking new features and improving data accuracy. Focused work delivered two major library upgrades with compatibility and data improvements: PyTibber to 0.31.2 and Mill to 0.12.5, including historic energy usage coordinator enhancements and clearer two-year data windows. These changes reduce external compatibility risks, enhance analytics capabilities, and support more reliable energy data across users.
