It worked the 2 times I left the house and went far away.
I don't get the goodbye notification when I go to my local coffeshop (its a little less than a block away).
The first time I went far away, it didn't work, but I didn't have WIFI on, so wonder if the GPS wasn't accurate enough or that is a bug?
I would be nice if you could set a the range of the perimeter (ie. larger with a House vs smaller with apartment) so it would actually give the Goodbye notification when I left my apartment.
I Also got a Goodbye, Welcome back and then Goodbye right after eachother when I left my place and drove around the block. I Wonder if should add a timer/delay so once a goodbye is triggered it waits a couple of minutes before it listens for a welcome (if that makes sense)
