Thanks for your questions!
The Play Store is the best place to get the most up to date apps.
Smart can be on any number of stations, but it does not need to be on all of them.
I will have to double check our Help page on Faults.
The controller does update automatically when we push new firmware out. It will go out overnight and most of the time, you won’t even know its chagned.
