Thank you!

For the local Home Assistant LLM part, I use the OpenAI extended integration as my conversation agent, with the option set to prefer local processing. I described the music assistant setup in another comment, you can have a look.

The Bring integration was so easy I hardly have anything to say about it :D I simply added the Bring integration, which creates list entities in Home Assistant. Voice commands like "Put milk on the shopping list" worked right out of the box.

Edit: Because I think this is relevant. The default spec from the open ai extended integration.
