Alarm control panel

The Alarm control panel integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] brings your home alarm system into Home Assistant. Whether you have a professionally installed security system or a DIY setup, this integration gives you full control over arming and disarming from anywhere. Imagine your alarm arming itself automatically when the last person leaves the house, disarming the moment you arrive home, sending an urgent notification to your phone when the alarm triggers at 3 AM, or quietly switching to night mode when bedtime rolls around. With Home Assistant watching over your security system, you get peace of mind knowing your home protects itself.

The state of an alarm panel entity

An alarm panel entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more] reflects the current state of your alarm system. Not every alarm panel supports every state or every arming mode. Home Assistant shows only the modes your hardware provides.

• Disarmed: the alarm is off. Sensors are not being monitored.
• Armed home: perimeter protection while you are inside. Doors and windows are monitored, but interior motion sensors are ignored so you move freely around the house.
• Armed away: full protection for when nobody is home. All sensors (perimeter and interior) are active.
• Armed night: similar to home mode, but tuned for sleeping. Typically covers perimeter sensors and selected interior zones while leaving bedroom areas free.
• Armed vacation: extended away protection for longer trips. Some systems enable additional monitoring or alerts in this mode.
• Armed custom bypass: armed with one or more zones deliberately skipped. Useful when you want to leave a specific door or window open while arming the rest of the system.
• Arming: the alarm is counting down its exit delay. You have a short window to leave the house before monitoring begins.
• Pending: the alarm detected a sensor trip and is counting down its entry delay. You have a short window to disarm before the alarm triggers.
• Triggered: the alarm has gone off. Sirens, notifications, and any other alert actions are active.
• Disarming: the alarm is in the process of being disarmed.
• Unavailable: the entity is currently unavailable.
• Unknown: the state is not yet known.

Using an alarm PIN code in actions

Some alarm panels require a PIN code to arm, disarm, or both. Others work without a PIN code. If your panel requires a PIN and you omit it or enter the wrong one, the action fails silently, and the alarm stays in its current state.

1. Check your alarm integration’s documentation to find out whether a PIN is required for arming, disarming, or both.

2. In your automation or script, add the alarm action.

3. If a PIN is needed, under Data, add code with your PIN:

   actions:
     - action: alarm_control_panel.alarm_disarm
       target:
         entity_id: alarm_control_panel.home_alarm
       data:
         code: "1234"
   

About the “Changed by” attribute

If your alarm panel supports it, the Changed by (changed_by) attribute tells you who last changed the alarm state. This is the name or identifier reported by your alarm system, for example a person’s name like “Franck Nijhof” or a key fob ID. You can use this attribute in notifications and automations to keep your household informed about who armed or disarmed the alarm.

Alarm automation examples

The real power of this integration is combining triggers and conditions into automations that protect your home without you having to think about it. Here are a few ideas to get you started.

Automation: arm the alarm when everyone leaves

When the last person leaves the house, arm the alarm in away mode automatically. No more wondering whether you remembered to set the alarm after rushing out the door.

• Trigger: Everyone leaves the home zone
• Action: Arm the alarm in away mode

alias: "Arm alarm when everyone leaves"
triggers:
  - trigger: zone
    entity_id: person.alex
    zone: zone.home
    event: leave
  - trigger: zone
    entity_id: person.jamie
    zone: zone.home
    event: leave
conditions:
  - condition: not
    conditions:
      - condition: zone
        entity_id:
          - person.alex
          - person.jamie
        zone: zone.home
actions:
  - action: alarm_control_panel.alarm_arm_away
    target:
      entity_id: alarm_control_panel.home_alarm

Automation: disarm when you arrive home

When you pull into the driveway, Home Assistant recognizes you are home and disarms the alarm. You walk through the front door without fumbling for a keypad or app.

• Trigger: Your person entity enters the home zone
• Action: Disarm the alarm

alias: "Disarm alarm on arrival"
triggers:
  - trigger: zone
    entity_id: person.alex
    zone: zone.home
    event: enter
actions:
  - action: alarm_control_panel.alarm_disarm
    target:
      entity_id: alarm_control_panel.home_alarm
    data:
      code: "1234"

Automation: send an urgent notification when the alarm triggers

If the alarm goes off, you want to know immediately, even if you are on the other side of town. This automation sends a critical notification to your phone the instant the alarm triggers.

• Trigger: Alarm triggered
• Action: Send a critical mobile notification

alias: "Notify on alarm trigger"
triggers:
  - trigger: alarm_control_panel.triggered
    target:
      entity_id: alarm_control_panel.home_alarm
    options:
      behavior: any
actions:
  - action: notify.mobile_app_phone
    data:
      title: "Alarm triggered"
      message: >
        Your home alarm has been triggered.
        Check your cameras immediately.

Automation: arm in night mode at bedtime

When bedtime arrives, switch the alarm to night mode so perimeter sensors stay active while you move freely inside the house.

• Trigger: Time reaches 23:00
• Action: Arm the alarm in night mode

alias: "Arm alarm at bedtime"
triggers:
  - trigger: time
    at: "23:00:00"
actions:
  - action: alarm_control_panel.alarm_arm_night
    target:
      entity_id: alarm_control_panel.home_alarm

Automation: notify the household who disarmed the alarm

If your alarm panel reports who made the change, you get a notification telling you exactly who disarmed the system. Handy for families who want to know when the kids got home, or for keeping a log of who opened up the house.

• Trigger: Alarm disarmed
• Action: Send a notification with the name of the person who disarmed it

alias: "Notify who disarmed the alarm"
triggers:
  - trigger: alarm_control_panel.disarmed
    target:
      entity_id: alarm_control_panel.home_alarm
    options:
      behavior: any
actions:
  - action: notify.notify
    data:
      title: "Alarm disarmed"
      message: >
        The alarm was disarmed
        by {{ state_attr(
        'alarm_control_panel.home_alarm',
        'changed_by') }}.
