I had a similar use case and played with the different options. Assuming you have an iOS device, I'd recommend:
- The Geofency App
- Hubitat driver to integrate with the app: [RELEASE] Geofency Presence
Pretty happy with it, I've been using it since I switched to Hubitat in December. I took a look at OwnTracks and I didn't personally care for the UI v.s. Geofency.
