If your morning is as crazy as ours? Is just trying to get the kids to eat their breakfast, dressed and be glad they have their shoes on when we leave the house is an daily accomplishment? Then I’m assuming sometimes you may just rush out and forget the arm the Iris system. If so then you may want to consider a Iris key fob.
Once you have this you may set the following magic rule “When the last key fob or pendant leaves then set home mode to ‘away’ under the section for “Who is at home”.
Once this set you shouldn’t have to worry about forgetting to arm your alarm as much anymore as long as everyone else also remembers to take their keys too.
