Home Assistant - Alarmo Presence Disarm

Home Assistant - Alarmo Presence Disarm#

2026-09-19#

Updated Home Assistant on root@10.1.2.200 after a false critical notification occurred as Marc arrived home.

Configuration decisions#

  • Marc and Nadine Home-area automations now call alarm_control_panel.alarm_disarm before sending their arrival notification.
  • The former “Auto Arm to HOME when we arrive HOME” behavior now keeps Alarmo disarmed when both people are home.
  • Alarmo’s built-in immediate “Notify Notify when triggered” automation is disabled.
  • A delayed Home Assistant automation, Alarmo - Delayed critical notification only while away, waits 10 seconds and notifies only if:
    • Alarmo is still triggered;
    • the arm mode is armed_away; and
    • neither Marc nor Nadine is in the home state.

This delay prevents a camera detection and geofence arrival update occurring almost simultaneously from producing a false critical notification.
