MQTT Scene

The mqtt scene platform lets you control your MQTT enabled scenes.

Configuration

To enable a MQTT scene in your installation, add the following to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file:

# Example configuration.yaml entry
mqtt:
  - scene:
      command_topic: zigbee2mqtt/living_room_group/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.

command_topic string (Optional)

The MQTT topic to publish payload_on to activate the scene.

device map (Optional)

Information about the device this scene is a part of to tie it into the device registry. Only works 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"]].

hw_version string (Optional)

The hardware version of the device.

identifiers string | list (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.

model_id string (Optional)

The model identifier of the device.

name string (Optional)

The name of the device.

serial_number string (Optional)

The serial number 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.

entity_category string (Optional)

The category of the entity.

entity_picture string (Optional)

Picture URL for the entity.

encoding string (Optional, default: utf-8)

The encoding of the published messages.

icon icon (Optional)

Icon for the scene.

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 Scene)

The name to use when displaying this scene.

object_id string (Optional)

Used instead of name for automatic generation of entity_id

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.

payload_on string (Optional, default: ON)

The payload that will be sent to command_topic when activating the MQTT scene.

platform string Required

Must be scene. Only allowed and required in MQTT auto discovery device messages.

qos integer (Optional, default: 0)

The maximum QoS level to be used when receiving and publishing messages.

retain boolean (Optional, default: false)

If the published message should have the retain flag on or not.

unique_id string (Optional)

An ID that uniquely identifies this scene entity. If two scenes have the same unique ID, Home Assistant will raise an exception. Required when used with device-based discovery.

Important

Make sure that your topic matches exactly. some-topic/ and some-topic are different topics.

Examples

In this section, you will find some real-life examples of how to use the MQTT Scene.

Full configuration

The example below shows a full configuration for a scene.

# Example configuration.yaml entry
mqtt:
  - scene:
      unique_id: living_room_party_scene
      name: "Party Scene"
      command_topic: "home/living_room/party_scene/set"
      availability:
        - topic: "home/living_room/party_scene/available"
      payload_on: "ON"
      qos: 0
      retain: true
      device:
        name: "Living Room"
        identifiers: "livingroom_lights"

Use with a JSON Payload

The example below shows a configuration using a JSON payload.

# Example configuration.yaml entry
mqtt:
  - scene:
      name: Living Room Blue Scene
      unique_id: living_room_blue_scene
      command_topic: "home/living_room/set"
      payload_on: '{"activate_scene": "Blue Scene"}'
