I went to RM for this one and two virtual switches. I created a virtual switch "Is Arm House" which is turned on when I hold the pico button by the front door. I also created a "Doors Open" virtual switch which turns on if any doors (except the front door which is open for me to leave) are open.
The trigger is the front door closing while the IsArmHouse is on and DoorsOpen switch is off. If I forgot to close all the doors, then I get notified and the house won't arm so I can go back and close it. I'm not happy that I had to create an extra virtual switch to hold the state of the button "hold", but that's the best way I could come up with for now.
