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.

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.

Backups were created on the Home Assistant host before the change:

Updated the delayed away-only notification message on root@10.1.2.200.

The notification now resolves each Alarmo open_sensors entity ID through its Home Assistant friendly_name.
The front-camera trigger is therefore presented as Front Camera (G5 Bullet) Vehicle detected instead of the raw entity dictionary.
Triggers, delay, away-state checks, and critical push sound settings were left unchanged.
