Knowing I had left for a run was key to knowing when I had returned from a run, rather than a trip in the car for example.

Maybe I'm having a brain fart, but I don't see how his solution has accomplished this.

Frankly it'd be way easier for the phone to use its GPS and accelerometer to decide he's on a run and just open the door when it reconnects to the wifi.

I don't see the run specific part either. It seems to work whether he went for a run or drive to the store. But using a device on the WiFi to sniff that the phone has reconnected and therefor the garage should open was better than putting the logic on the phone. For one thing, it makes it so he can trivially add/remove devices with this functionality.

Frankly, if he wanted to do something with GPS on his phone, timing anything to the reconnection of WiFi is just worse than sending a signal to a public facing web server when he crosses a geofence.

I wonder if this will continue to work, as some phones (I believe all iPhones by default now, for instance) cycle MAC addresses.
