You can use a button press to trigger an automation block on the panel. For example, I have a button I can hit that bypasses the motion detectors in the house and then arm the alarm away because I left my dog (a big boxer) at home.
So, I created a button called "Away Max" (max is his name).
Then in the automation programming, I have:
When AWAY MAX
BYPASS Hall Motion
BYPASS LR Motion
BYPASS MBR Motion
ARM AWAY
Then I can either start Haiku on my phone and hit the "Away Max" button and off we go.
