Welcome to Home Assistant Daily for February 1st through 8th, 2026.
Fifty pull requests merged with 99 additional commits this week.
Major infrastructure work dominated development. The team upgraded ruff to version 0.15.0, requiring extensive code reformatting across the entire codebase. Multiple PRs reformatted lambda functions, cleaned up unnecessary brackets in exception statements, and improved string splitting performance. These changes prepare the project for enhanced code quality standards.
Several AI conversation integrations received critical bug fixes for JSON serialization of time objects. OpenAI, Google Generative AI, Open Router, Ollama, and Cloud conversation components all had issues where datetime objects couldn't be properly serialized in tool results, causing failures when the assist pipeline preferred local command handling.
Feature additions were more limited but meaningful. Control4 climate integration gained fan mode support for Auto, Circulate, and On modes. Green Planet Energy added timestamp sensors for highest and lowest price times during day and night periods. Waterfurnace sensors now include proper device information for better organization.
The 2026.2.1 patch release addressed 21 linked issues, including dependency updates for Tuya climate, Tesla Fleet backup reserve sensors, and multiple other components. Breaking changes included removing redundant preset modes in Tuya climate and fixing backup reserve sensor classifications across Tesla integrations.
Template image platform moved to the new entity framework, simplifying the codebase. Bad entity ID detection became more lenient to reduce impact from recent validation changes. Several integrations received dependency bumps including librehardwaremonitor-api, snapcast, and Nintendo Parental Controls.
Testing improvements included better coverage for Shelly initialization and Xbox remote action exceptions. String corrections standardized "text-to-speech" and "speech-to-text" capitalization across Google Generative AI and ElevenLabs integrations.
Additional commits focused on dependency updates for Essent dynamic pricing and continued JSON serialization fixes across conversation platforms.
Next week should see continued stability improvements as the ruff upgrade settles and developers return to feature development.
That's your Home Assistant development update. Thanks for listening.
