Was going to ask the same thing. I joked with my wife that we could do geofencing out here but the cell data coverage is crap right at the end of the driveway and as soon as you start down it, the phones are in the middle of figuring out that they see the home WiFi and changing networks and I suspect it would go something like this...
Hit the driveway, drive 850’ down it, by now phone is on WiFi but still doing the DHCP thing, sit in front of garage door where outdoor WiFi is the weakest of anywhere on the property, especially 5 GHz and I have the phones locked to the 5 GHz network for unrelated reasons, a couple minutes later the phone finally has switched networks, is running on WiFi with massive packet loss, but geofencing finally knows where it is now, and pops the door open.
WiFi immediately gets better because the doors are steel. Now that we don’t need it anymore. Hahaha.
