Same experience for me and HomeKit and HA. And the "investment" into HA seems to be better and better over time with AI.

LLMs/AI has taken my HA usage to another level. It worked great and I loved it pre-LLM but armed with LLMs I can do some amazing automations and tweak them with my voice [0].

I recently tasked Claude with creating a vector floorplan of my house, then added icons for lights/fans/etc (Claude wrote a little tool where I could drag everything where it goes), and then set it up in HA so I can click on devices on the floorplan to toggle them. It's so cool.
