My use case would be to automatically update the status on the phone to home or away based on a trigger, the obvious one being if it's connected (or not) to the Almond+ via WiFi. I leave home, the WiFi disconnects, the status on the phone changes to away, so I get all alerts for sensors with 'away' or 'always' as the alert setting, and when I come home and connect to WiFi the status changes to 'home' and I get alerts for 'home' and 'always' sensors. I honestly can't think of any other scenario that would makes sense.
