@Stan Hello Stan, V2.4 works well. I have also added Arm Night Stay Tile to your program, you basically arm stay twice to activate Night stay. This allows user to arm all perimeter and selected motions around the house during night. It works. I changed the tile layout in the main tile as there was no space, moved the Chime tile to the end and now I have stay and night stay as two tiles on top of the main screen. I can share the code with any other user who needs this mode.
I am making progress

Next challenge : We all need to figure out how to report individual sensor alarm in the vista20p setup to trigger separate actions in smartapp. The open or closed zones are being reported in the smartapp, what we cannot do in current app is to use them to trigger various actions.
