Alarm Auto Arming

Automate the arming and disarming of the built-in Home Assistant alarm control panel, with additional support for manual override via remote control buttons, and mobile push actionable notifications.

Setup

Register this GitHub repo as a custom repo in your HACS configuration.

Notifications will work with any HomeAssistant notification implementation but works best with Supernotifier for multi-channel notifications with mobile actions.

Diurnal settings

Arming can happen strictly by sunset and sunrise. Alternatively, a defined sleep_start and sleep_end can be specified, so there’s more predictability, especially for high latitudes where sunrise varies wildly through the year.

Similarly, there’s a sunrise_cutoff option to prevent alarm being armed at 4am if you live far North, like Norway or Scotland.

Throttling

To guard against loops, or other reasons why arming might be triggered too often, rate limiting is applied around the arm call, limited to a set number of calls within the past so many seconds.

Example Configuration

Configure in the Home Assistant config, either as a block in a config file, or as a file of its own using an include.

Alarm Panel Configuration

Autoarm will work with any Home Assistant Alarm Control Panel based integration, whether with a physical panel, virtual, virtual with generic switches for some modes, or entirely automated.

If you don’t already have an alarm panel, set up a default manual as below, which creates the state machine for armed/disarmed status. This is all you need in the way of alarm support for AutoArm to function. You can also choose whether a PIN code is needed or not to arm or disarm.

alarm_control_panel:
  - platform: manual
    name: Home Alarm Control
    code_arm_required: false
    arming_time: 0
    delay_time: 0
    disarm_after_trigger: false
    trigger_time: 0

See Home Assistant Manual Control Panel docs for more info.

There’s also a handy Dashboard Alarm Panel widget to add to your Home Assistant dashboard.
