I am trying to setup home assistant and it fails on start.

So far I have the configuration

  # HOME ASSISTANT

The home-assistant.log contains lines like

  File "/nix/store/62ca018946zd2hm8a959qqhq6p8lph6y-homeassistant-2025.11.3/lib/python3.13/site-packages/homeassistant/components/ai_task/__init__.py", line 35, in <module>

    from homeassistant.components.conversation import (

    )

    from hassil.recognize import RecognizeResult
ModuleNotFoundError: No module named 'hassil'

How should I solve this?

There is a wiki section that seems to relate to this but it is unclear. It partly explains how to find a component for a missing package but not what I should do with that information. Should I add this component manually to services.home-assistant.extraComponents? And any or all components that contain hassil?
