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 Assistant and vice-versa, keeping the device and Home Assistant in-sync.
To enable MQTT Number in your installation, add the following to your
# Example configuration.yaml entry mqtt: number: - command_topic: my-device/threshold
The configuration format of manual configured MQTT items has changed.
The old format that places configurations under the
number platform key
should no longer be used and is deprecated.
The above example shows the new and modern way, this is the previous/old example:
number: - platform: mqtt command_topic: my-device/threshold
A list of MQTT topics subscribed to receive availability (online/offline) updates. Must not be used together with

The payload that represents the unavailable state.
The MQTT topic subscribed to receive availability (online/offline) updates. Must not be used together with
availability is configured, this controls the conditions needed to set the entity to
available. Valid entries are
latest. If set to
payload_available must be received on all configured availability topics before the entity is marked as online. If set to
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_not_available received on any configured availability topic controls the availability.

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. At least one of identifiers or connections must be present to identify the device.
A link to the webpage that can manage the configuration of this device. Can be either an HTTP or HTTPS link.
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"].
A list of IDs that uniquely identify the device. For example a serial number.
Flag which defines if the entity should be enabled when first added.
The encoding of the payloads received and published messages. Set to
"" to disable decoding of incoming payload.
The category of the entity.
Defines a template to extract the JSON dictionary from messages received on the
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.
Control how the number should be displayed in the UI. Can be set to
slider to force a display mode.
Flag that defines if number works in optimistic mode.

The maximum QoS level of the state topic. Default is 0 and will also be used to publishing messages.
If the published message should have the retain flag on or not.
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.
