Home Assistant 2026.10 is unusually relevant to a house full of connected devices. Its official release notes describe a new MCP card in the AI settings page that can expose selected home functions to AI tools such as Cursor or ChatGPT without hand-assembling server URLs.
The same release adds Apple iCloud calendar and Reminders integration, plus improved real-time reporting for some Roborock vacuums. These are useful capabilities, but they apply only if you actually run Home Assistant and the particular device integration supports them.
The safe experiment is to read the release notes, test with one low-stakes device or scene, and explicitly limit which entities an AI agent may control. Do not grant a general-purpose agent every door lock, camera or automation simply because the default setup makes that easy.
