I could not find a new thread for this specifically, but I noticed the locations are tied together between the new and classic app. So using the following automatons in the new app I essentially tie the arm/stay/disarm setting to the classic app based on location. essentially letting me control the STHM in the new app via webCore or routines. This is a work around but has proven reliable since the new app came out last week, I like the idea of a delay for the alarm in the new app.
Yes, it became available with the latest app update. You can also arm/disarm using location services (presence) now but this part is not available through webcore, only the process you mentioned above.
there was a number of us got rather excited about this release
