I am using Apple Home's built-in geofencing feature. I simply created a Virtual Presence with Switch device on my Hubitat hub. Then I exposed this device to Apple Home using Hubitat's built-in HomeKit integration. I then created two Apple Home Automations, one for arriving and another for departing, that simply turn 'on' and 'off' the Hubitat device. For this to work reliably, you will need an always on device on your home network that can act as an Apple Home 'Hub', like an AppleTV or HomePod Mini.
This has been extremely reliable for us.
You can also use Locative, as it works very reliably as well.
