To enable MQTT lawn mower in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
mqtt:
  - lawn_mower:
      command_topic: topic
      name: "Test Lawn Mower"

Configuration Variables

activity_state_topic string (Optional)

The MQTT topic subscribed to receive an update of the activity. Valid activities are mowing, paused, docked, and error. Use value_template to extract the activity state from a custom payload. When payload none is received, the activity state will be reset to unknown.

activity_value_template template (Optional)

Defines a template to extract the value.

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 the device’s availability from the topic. To determine the device’s availability, the 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.

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, the result of this template will be compared to payload_available and payload_not_available.

device map (Optional)

Information about the device this lawn mower is a part of to tie it into the device registry. Only works when the unique_id is set. At least one of the 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://, https://, or an internal homeassistant:// URL.

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 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.

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 the device topology in Home Assistant.

dock_command_template template (Optional)

Defines a template to generate the payload to send to dock_command_topic. The value parameter in the template will be set to dock.

dock_command_topic string (Optional)

The MQTT topic that publishes commands when the service lawn_mower.dock service call is executed. The value dock is published when the service is called. Use a dock_command_template to publish a custom format.

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 the incoming payload.

entity_category string (Optional)

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.

json_attributes_topic string (Optional)

The MQTT topic subscribed to receive a JSON dictionary payload and then set as entity attributes. Implies force_update of the current activity state when a message is received on this topic.

name string (Optional)

The name of the lawn mower. Can be set to null if only the device name is relevant.

object_id string (Optional)

Used instead of name for automatic generation of entity_id

optimistic boolean (Optional)

Flag that defines if the lawn mower works in optimistic mode.

Default:

true if no activity_state_topic defined, else false.

pause_command_template template (Optional)

Defines a template to generate the payload to send to pause_command_topic. The value parameter in the template will be set to pause.

pause_command_topic string (Optional)

The MQTT topic that publishes commands when the service lawn_mower.pause service call is executed. The value pause is published when the service is called. Use a pause_command_template to publish a custom format.

qos integer (Optional, default: 0)

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

start_mowing_template template (Optional)

Defines a template to generate the payload to send to start_mowing_command_topic. The value parameter in the template will be set to start_mowing.

start_mowing_command_topic string (Optional)

The MQTT topic that publishes commands when the service lawn_mower.start_mowing service call is executed. The value start_mowing is published when the service is called. Use a start_mowing_command_template to publish a custom format.

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 lawn mower. If two lawn mowers have the same unique ID, Home Assistant will raise an exception.

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

Example

The example below shows how to use a single command topic with a command template.

# Example configuration.yaml entry
mqtt:
  - lawn_mower:
      name: "Lawn Mower Plus"
      activity_state_topic: "lawn_mower_plus/state"
      activity_value_template: "{{ value_json.activity }}" 
      pause_command_topic: "lawn_mower_plus/set"
      pause_command_template: '{"activity": "{{ value }}"}' 
      dock_command_topic: "lawn_mower_plus/set"
      dock_command_template: '{"activity": "{{ value }}"}' 
      start_mowing_command_topic: "lawn_mower_plus/set"
      start_mowing_command_template: '{"activity": "{{ value }}"}'
