have you listened to Automators 38: Simon Leeb and Pushcut? there are a few examples in there in combination with Pushcut.
one thing I find useful is a get-out-of-here notification “at 9 pm when I am in the office” - where office is actually an iBeacon.
another fun thing are reminders to open an app when you get to an iBeacon/location (say a McDonalds 
)
