In the tutorial, I cover the steps necessary to bring up a full-featured system that group sensors by type, distinguished between "armed away" and "armed home", arms and disarms with grace periods and audible feedback, and even auto-arms and auto-disarms depending on presence.
All feedback is welcome! (But I can only promise corrections and additions work load and family permitting.)
