MQTT Alarm Control Panel

The mqtt alarm panel platform enables the possibility to control MQTT capable alarm panels. The Alarm icon will change state after receiving a new state from state_topic. If these messages are published with RETAIN flag, the MQTT alarm panel will receive an instant state update after subscription and will start with the correct state. Otherwise, the initial state will be unknown.

The integration will accept the following states from your Alarm Panel (in lower case):

  • disarmed
  • armed_home
  • armed_away
  • armed_night
  • armed_vacation
  • armed_custom_bypass
  • pending
  • triggered
  • arming
  • disarming

The integration can control your Alarm Panel by publishing to the command_topic when a user interacts with the Home Assistant frontend.

Configuration

To enable this platform, add the following lines to your configuration.yaml:

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

Configuration Variables

Looking for your configuration file?
availability list (Optional)

A list of MQTT topics subscribed to receive availability (online/offline) updates. Must not be used together with availability_topic.

payload_available string (Optional, default: online)

The payload that represents the available state.

payload_not_available string (Optional, default: offline)

The payload that represents the unavailable state.

topic string Required

An MQTT topic subscribed to receive availability (online/offline) updates.

value_template template (Optional)

Defines a template to extract device’s availability from the topic. To determine the devices’s availability result of this template will be compared to payload_available and payload_not_available.

availability_mode string (Optional, default: latest)

When availability is configured, this controls the conditions needed to set the entity to available. Valid entries are all, any, and latest. If set to all, payload_available must be received on all configured availability topics before the entity is marked as online. If set to any, payload_available must be received on at least one configured availability topic before the entity is marked as online. If set to latest, the last payload_available or payload_not_available received on any configured availability topic controls the availability.

availability_template template (Optional)

Defines a template to extract device’s availability from the availability_topic. To determine the devices’s availability result of this template will be compared to payload_available and payload_not_available.

availability_topic string (Optional)

The MQTT topic subscribed to receive availability (online/offline) updates. Must not be used together with availability.

code string (Optional)

If defined, specifies a code to enable or disable the alarm in the frontend. Note that the code is validated locally and blocks sending MQTT messages to the remote device. For remote code validation, the code can be configured to either of the special values REMOTE_CODE (numeric code) or REMOTE_CODE_TEXT (text code). In this case, local code validation is bypassed but the frontend will still show a numeric or text code dialog. Use command_template to send the code to the remote device. Example configurations for remote code validation can be found here.

code_arm_required boolean (Optional, default: true)

If true the code is required to arm the alarm. If false the code is not validated.

code_disarm_required boolean (Optional, default: true)

If true the code is required to disarm the alarm. If false the code is not validated.

code_trigger_required boolean (Optional, default: true)

If true the code is required to trigger the alarm. If false the code is not validated.

command_template string (Optional, default: action)

The template used for the command payload. Available variables: action and code.

command_topic string Required

The MQTT topic to publish commands to change the alarm state.

device map (Optional)

Information about the device this alarm panel is a part of to tie it into the device registry. Only works through MQTT discovery and when unique_id is set. At least one of identifiers or connections must be present to identify the device.

configuration_url string (Optional)

A link to the webpage that can manage the configuration of this device. Can be either an HTTP or HTTPS link.

connections list (Optional)

A list of connections of the device to the outside world as a list of tuples [connection_type, connection_identifier]. For example the MAC address of a network interface: "connections": [["mac", "02:5b:26:a8:dc:12"]].

identifiers list | string (Optional)

A list of IDs that uniquely identify the device. For example a serial number.

manufacturer string (Optional)

The manufacturer of the device.

model string (Optional)

The model of the device.

name string (Optional)

The name of the device.

suggested_area string (Optional)

Suggest an area if the device isn’t in one yet.

sw_version string (Optional)

The firmware version of the device.

via_device string (Optional)

Identifier of a device that routes messages between this device and Home Assistant. Examples of such devices are hubs, or parent devices of a sub-device. This is used to show device topology in Home Assistant.

enabled_by_default boolean (Optional, default: true)

Flag which defines if the entity should be enabled when first added.

encoding string (Optional, default: utf-8)

The encoding of the payloads received and published messages. Set to "" to disable decoding of incoming payload.

entity_category string (Optional, default: None)

The category of the entity.

icon icon (Optional)

Icon for the entity.

json_attributes_template template (Optional)

Defines a template to extract the JSON dictionary from messages received on the json_attributes_topic. Usage example can be found in MQTT sensor documentation.

json_attributes_topic string (Optional)

The MQTT topic subscribed to receive a JSON dictionary payload and then set as sensor attributes. Usage example can be found in MQTT sensor documentation.

name string (Optional, default: MQTT Alarm)

The name of the alarm.

object_id string (Optional)

Used instead of name for automatic generation of entity_id

payload_arm_away string (Optional, default: ARM_AWAY)

The payload to set armed-away mode on your Alarm Panel.

payload_arm_home string (Optional, default: ARM_HOME)

The payload to set armed-home mode on your Alarm Panel.

payload_arm_night string (Optional, default: ARM_NIGHT)

The payload to set armed-night mode on your Alarm Panel.

payload_arm_vacation string (Optional, default: ARM_VACATION)

The payload to set armed-vacation mode on your Alarm Panel.

payload_arm_custom_bypass string (Optional, default: ARM_CUSTOM_BYPASS)

The payload to set armed-custom-bypass mode on your Alarm Panel.

payload_available string (Optional, default: online)

The payload that represents the available state.

payload_disarm string (Optional, default: DISARM)

The payload to disarm your Alarm Panel.

value_template template (Optional)

Defines a template to extract the value.

Examples

In this section you find some real-life examples of how to use this alarm control panel.

Configuration with local code validation

The example below shows a full configuration with local code validation.

# Example using text based code with local validation configuration.yaml
alarm_control_panel:
  - platform: mqtt
    name: "Alarm Panel With Numeric Keypad"
    state_topic: "alarmdecoder/panel"
    value_template: "{{value_json.state}}"
    command_topic: "alarmdecoder/panel/set"
    code: mys3cretc0de

Configurations with remote code validation

The example below shows a full configuration with remote code validation and command_template.

# Example using text code with remote validation configuration.yaml

  - platform: mqtt
    name: "Alarm Panel With Text Code Dialog"
    state_topic: "alarmdecoder/panel"
    value_template: "{{ value_json.state }}"
    command_topic: "alarmdecoder/panel/set"
    code: REMOTE_CODE_TEXT
    command_template: "{ action: '{{ action }}', code: '{{ code }}'}"

# Example using numeric code with remote validation configuration.yaml

When your MQTT connection is not secured, this will send your secret code over the network unprotected!
