I've just signed up for If This Then That and I'm trying to compose a recipe for the following situation.
My kids don't have their own Google Calendar accounts; we use the family account for appointments for them. For instance, "play date Kid A at classmate's place". Since I've added the location, I'll get a reminder from Google Now when I need to leave to drop him off. But I'd like a reminder when I need to leave to pick him up again.
For that, I'd like to automatically add a second appointment at the end of the first one, at the same location, that has a duration of five or ten minutes.
So what I had in mind, is something like
IF I have an event in my calendar with the name of one of my kids AND it has a location AND the event has started THEN add an event to my calendar: for that location starting when the original event ends for a duration of X minutes
But I don't know how to read the location of an event, nor how to read its from and to times.
Of course, this doesn't have to be done with IFTTT. Similar apps are okay.
I've also explored the options for Google Calendar's reminders, to have a reminder after the start of an event, but I couldn't get that to work. Also, it's not so much the reminders of the event I'm after, but rather Google Now's "leave now for X" reminders, which take your travel time into account.
