It fills me with ick, but I just connected OpenAI to my Home Assistant. It’s not doing anything like controlling my home or doing anything “intelligent” (as LLMs are, after all, merely Stochastic Parrots).
No, all it’s there for is to answer questions that we throw at it. My wife really likes asking Siri random stuff, and she’d miss it when it goes, and so she was happy to see the same replicated in the HA Voice.
