I’m a brand new newbie to SmartThings.
There are two nuisances that are currently at the top of my list.
The dashboard does not accurately reflect the house state. E.g. it will show all present, even though I get the push notifications that folks have left, and you can see the activities in the activity stream. Same for door state. Force quitting and restarting seems to resolve that issue.
Presence on the Galaxy S4 seems to be very spotty. Sometimes just opening the app will register a presence, sometimes a restart is required, and occasionally it works. The Galaxy S5 seems much better. Both are on the latest Verizon Android version.
On the plus side, other than a couple of nuisances, I’m very happy with the overall system. Hopefully the Android app will only get better over time.
