Of course you can control Hubitat devices through the HomePod mini! (& IPad)
(at least most of them).
One of the easiest approaches is to:
- setup & define all your devices in Hubitat; make sure everything all works natively in Hubitat.
- Use the superb HomeBridge V2 (from Tonesto) to send via MakerApi all that info via a RaspberryPi to your HomePod.
- What is very amazing is that with all those interfaces, status and control is amazingly fast
It sounds more complicated than it is. Once it's setup, it requires very little, if any maintenance.
This will take some time, but there are many here who do just that (they are Apple households).
