MQTT Fan

The mqtt fan platform lets you control your MQTT enabled fans.

In an ideal scenario, the MQTT device will have a state_topic to publish state changes. If these messages are published with a RETAIN flag, the MQTT fan will receive an instant state update after subscription and will start with the correct state. Otherwise, the initial state of the fan will be false / off.

When a state_topic is not available, the fan will work in optimistic mode. In this mode, the fan will immediately change state after every command. Otherwise, the fan will wait for state confirmation from the device (message from state_topic).

Optimistic mode can be forced even if a state_topic is available. Try to enable it if you are experiencing incorrect fan operation.

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

# Example configuration.yml entry
fan:
  - platform: mqtt
    command_topic: "bedroom_fan/on/set"

Configuration Variables

name

(string)(Optional)The name of the fan.

Default value: MQTT Fan

command_topic

(string)(Required)The MQTT topic to publish commands to change the fan state.

state_topic

(string)(Optional)The MQTT topic subscribed to receive state updates.

payload_on

(string)(Optional)The payload that represents the running state.

Default value: true

payload_off

(string)(Optional)The payload that represents the stop state.

Default value: false

state_value_template

(string)(Optional)Defines a template to extract a value from the state.

qos

(integer)(Optional)The maximum QoS level of the state topic.

Default value: 0

optimistic

(boolean)(Optional)Flag that defines if lock works in optimistic mode

Default value: true if no state topic defined, else false.

retain

(boolean)(Optional)If the published message should have the retain flag on or not.

Default value: true

oscillation_state_topic

(string)(Optional)The MQTT topic subscribed to receive oscillation state updates.

oscillation_command_topic

(string)(Optional)The MQTT topic to publish commands to change the oscillation state.

payload_oscillation_on

(string)(Optional)The payload that represents the oscillation on state.

Default value: oscillate_on

payload_oscillation_off

(string)(Optional)The payload that represents the oscillation off state.

Default value: oscillate_off

oscillation_value_template

(string)(Optional)Defines a template to extract a value from the oscillation.

speed_state_topic

(string)(Optional)The MQTT topic subscribed to receive speed state updates.

speed_command_topic

(string)(Optional)The MQTT topic to publish commands to change speed state.

payload_low_speed

(string)(Optional)The payload that represents the fan’s low speed.

Default value: low

payload_medium_speed

(string)(Optional)The payload that represents the fan’s medium speed.

Default value: medium

payload_high_speed

(string)(Optional)The payload that represents the fan’s high speed.

Default value: high

speed_value_template

(string)(Optional)Defines a template to extract a value from the speed payload.

speeds

(string list)(Optional)List of speeds this fan is capable of running at. Valid entries are off, low, medium, and high.

availability_topic

(string)(Optional)The MQTT topic subscribed to receive availability (online/offline) updates.

payload_available

(string)(Optional)The payload that represents the available state.

Default value: online

payload_not_available

(string)(Optional)The payload that represents the unavailable state.

Default value: offline

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