Home Assistant Is the Hub

You probably wount t get in a car hub a if you don't have i acar hub. You could get a zigbe dongle am for home assistant am, pluck am that in and pare the car stuff with that and then share it back to home kit. But that is a lot more work than just buying the acara hub. For most people, i would not recommend that route. If you're really interested in all theo assistant stuff and trying to minimize the number of a hubs you've got, then then home assistant is wonderful.
