MQTT Text


The mqtt Text platform allows you to integrate devices that show text that can be set remotely. Optionally the text state can be monitored too using MQTT.

Configuration

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

# Example configuration.yaml entry
mqtt:
  - text:
      command_topic: command-topic

Configuration Variables

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

command_template template (Optional)

Defines a template to generate the payload to send to command_topic.

command_topic string Required

The MQTT topic to publish the text value that is set.

device map (Optional)

Information about the device this of text capability 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://, 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 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)

The category of 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 select state when a message is received on this topic.

max integer (Optional, default: 255)

The maximum size of a text being set or received (maximum is 255).

min integer (Optional, default: 0)

The minimum size of a text being set or received.

mode string (Optional, default: text)

The mode off the text entity. Must be either text or password.

name string (Optional, default: MQTT Text)

The name of the text entity. 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

pattern string (Optional)

A valid regular expression the text being set or received must match with.

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.

state_topic string (Optional)

The MQTT topic subscribed to receive text state updates. Text state updates should match the pattern (if set) and meet the size constraints min and max. Can be used with value_template to render the incoming payload to a text update.

unique_id string (Optional)

An ID that uniquely identifies this Select. If two Selects have the same unique ID Home Assistant will raise an exception.

value_template template (Optional)

Defines a template to extract the text state value from the payload received on state_topic.

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

Examples

This is an example of a manual configured MQTT text item.

# Example configuration.yaml entry
mqtt:
  - text:
      name: "Remote LCD screen"
      icon: mdi:ab-testing
      mode: "text"
      command_topic: "txt/cmd"
      state_topic: "txt/state"
      min: 2
      max: 20
