MQTT Number

The mqtt Number platform allows you to integrate devices that might expose configuration options through MQTT into Home Assistant as a Number. Every time a message under the topic in the configuration is received, the number entity will be updated in Home Assisant and vice-versa, keeping the device and Home Assistant in-sync.

Configuration

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

# Example configuration.yaml entry
number:
  - platform: mqtt
    command_topic: my-device/threshold

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.

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.

command_topic string (Optional)

The MQTT topic to publish commands to change the number.

device map (Optional)

Information about the device this Number is a part of to tie it into the device registry. Only works through MQTT discovery and when unique_id is set.

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)

model string (Optional)

The model of the device.

name string (Optional)

The name of the device.

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.

icon icon (Optional)

Icon for the number.

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 number attributes. Implies force_update of the current number state when a message is received on this topic.

name string (Optional)

The name of the Number.

optimistic boolean (Optional)

Flag that defines if number works in optimistic mode.

Default:

true if no state_topic defined, else false.

qos integer (Optional, default: 0)

The maximum QoS level of the state topic. Default is 0 and will also be used to 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 number values.

unique_id string (Optional)

An ID that uniquely identifies this Number. If two Numbers 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.
