ADT/Smart Things Hub Qs - Help Plzzz!

I have some questions about the ADT/ST combo hub that I am hoping someone can answer for me. I already bought and setup the ADT/ST hub and I am really disappointed so far…

  1. Is it possible to arm/disarm the alarm based on location? I currently can’t set this with a routine, and was hoping to do this since I cant configure how the away/home settings work for the alarm.

  2. Someone mentioned in another thread the ADT/ST hub is missing a number of apps. I noticed there were hardly any apps in my smart apps section. Is this BC I’m using the ADT hub?

  3. Is it possible to use the ST2 hub and the ADT/ST hub at the same time? If so what would the trade offs be?
