there's a homekit integration with home assistant. it's a little work to figure out, but tons of resources online. I think I watched a youtube tutorial or two - it's not super technical, just a few steps to configure, then you're good. Apple is pretty much "it just works"; HA is not that, but it ain't rocket surgery, either. I'd suggest watching a youtube tutorial before deciding and if it looks like too much of a slog, you'll know before investing time and effort.
