Home Assistant

Manual Alarm Control Panel with MQTT Support

This platform extends the manual alarm by adding support for MQTT control of the alarm by a remote device. It can be used to create external keypads which simply change the state of the manual alarm in Home Assistant.

It’s essentially the opposite of the MQTT Alarm Panel which allows Home Assistant to observe an existing, fully-featured alarm where all of the alarm logic is embedded in that physical device.

The component will accept the following commands from your Alarm Panel via the command_topic:

  • DISARM
  • ARM_HOME
  • ARM_AWAY
  • ARM_NIGHT

When the state of the manual alarm changes, Home Assistant will publish one of the following states to the state_topic:

  • ‘disarmed’
  • ‘armed_home’
  • ‘armed_away’
  • ‘armed_night’
  • ‘pending’
  • ‘triggered’

To use your panel in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
alarm_control_panel:
  - platform: manual_mqtt
    state_topic: home/alarm
    command_topic: home/alarm/set

Configuration variables:

The following configuration variables from the base manual alarm platform are available:

  • name (Optional): The name of the alarm. Default is “HA Alarm”.
  • code (Optional): If defined, specifies a code to enable or disable the alarm in the frontend. This code is not required for MQTT interactions.
  • code_template (Optional): If defined, returns a code to enable or disable the alarm in the frontend; an empty string disables checking the code. Inside the template, the variables from_state and to_state identify the current and desired state. Only one of code and code_template can be specified.
  • delay_time (Optional): The time in seconds of the pending time before triggering the alarm. Default is 0 seconds.
  • pending_time (Optional): The time in seconds of the pending time before effecting a state change. Default is 60 seconds.
  • trigger_time (Optional): The time in seconds of the trigger time in which the alarm is firing. Default is 120 seconds.
  • disarm_after_trigger (Optional): If true, the alarm will automatically disarm after it has been triggered instead of returning to the previous state.
  • armed_home/armed_away/armed_night/disarmed/triggered (Optional): State specific settings
    • delay_time (Optional): State specific setting for delay_time (all states except triggered)
    • pending_time (Optional): State specific setting for pending_time (all states except disarmed)
    • trigger_time (Optional): State specific setting for trigger_time (all states except triggered)

See the documentation for the manual alarm platform for a description.

Additionally, the following MQTT configuration variables are also available:

  • state_topic (Required): The MQTT topic HA will publish state updates to.
  • command_topic (Required): The MQTT topic HA will subscribe to, to receive commands from a remote device to change the alarm state.
  • qos (Optional): The maximum QoS level for subscribing and publishing to MQTT messages. Default is 0.
  • payload_disarm (Optional): The payload to disarm this Alarm Panel. Default is “DISARM”.
  • payload_arm_home (Optional): The payload to set armed-home mode on this Alarm Panel. Default is “ARM_HOME”.
  • payload_arm_away (Optional): The payload to set armed-away mode on this Alarm Panel. Default is “ARM_AWAY”.
  • payload_arm_night (Optional): The payload to set armed-night mode on this Alarm Panel. Default is “ARM_NIGHT”.

In the configuration example below:

  • The disarmed state never triggers the alarm.
  • The armed_home state will leave no time to leave the building or disarm the alarm.
  • While other states state will give 30 seconds to leave the building before triggering the alarm, and 20 seconds to disarm the alarm when coming back.
# Example configuration.yaml entry
alarm_control_panel:
  - platform: manual_mqtt
    state_topic: home/alarm
    command_topic: home/alarm/set
    pending_time: 30
    delay_time: 20
    trigger_time: 4
    disarmed:
      trigger_time: 0
    armed_home:
      pending_time: 0
      delay_time: 0

Examples

Refer to the Manual Alarm Control page for some real life examples of how to use this panel.

MQTT Control

The state of this alarm can be controlled using MQTT. Ensure you’ve configured that before adding this component.

To change the state of the alarm, publish one of the following messages to the command_topic:

  • DISARM
  • ARM_HOME
  • ARM_AWAY
  • ARM_NIGHT

To receive state updates from HA, subscribe to the state_topic. Home Assistant will publish a new message whenever the state changes:

  • disarmed
  • armed_home
  • armed_away
  • armed_night
  • pending
  • triggered
