:description: Instructions for setting up the base fan component.

|
|
|
|
With the ``fan`` domain you can create components that appear as fans in
|
|
the Home Assistant frontend. A fan can be switched ON or OFF, optionally
|
|
has a speed level between 1 and the maximum supported speed level of the fan, and can have an
|
|
oscillate and direction output.
|
|
|
|
This component restores its state on reboot/reset.

Base Fan Configuration
|
|
----------------------
|
|
|
|
.. code-block:: yaml
|
|
|
|
fan:
|
|
- platform: ...
|
|
name: ...
|
|
|
|
Configuration variables:
|
|
|
|
- **name** (**Required**, string): The name of the fan.
|
|
- **icon** (*Optional*, icon): Manually set the icon to use for the fan in the frontend.
|
|
- **internal** (*Optional*, boolean): Mark this component as internal. Internal components will
|
|
not be exposed to the frontend (like Home Assistant). Only specifying an ``id`` without
|
|
a ``name`` will implicitly set this to true.
|
|
- **disabled_by_default** (*Optional*, boolean): If true, then this entity should not be added to any client's frontend,
|
|
(usually Home Assistant) without the user manually enabling it (via the Home Assistant UI).
|
|
Requires Home Assistant 2021.9 or newer. Defaults to ``false``.
|
|
- **entity_category** (*Optional*, string): The category of the entity.
|
|
See https://developers.home-assistant.io/docs/core/entity/#generic-properties
|
|
for a list of available options. Requires Home Assistant 2021.11 or newer.
|
|
Set to ``""`` to remove the default entity category.
|
|
|
|
MQTT options:
|
|
|
|
- **oscillation_state_topic** (*Optional*, string): The topic to
|
|
publish fan oscillation state changes to.
|
|
- **oscillation_command_topic** (*Optional*, string): The topic to
|
|
receive oscillation commands on.
|
|
- **speed_level_state_topic** (*Optional*, int): The topic to publish
|
|
numeric fan speed state changes to (range: 0 to speed count).
|
|
- **speed_level_command_topic** (*Optional*, int): The topic to receive
|
|
numeric speed commands on (range: 0 to speed count).
|
|
- **speed_state_topic** (*Optional*, string): The topic to publish fan
|
|
speed state changes to (options: LOW, MEDIUM, HIGH).
|
|
- **speed_command_topic** (*Optional*, string): The topic to receive
|
|
speed commands on (options: LOW, MEDIUM, HIGH).
|
|
- All other options from :ref:`MQTT Component <config-mqtt-component>`.
|
|
|
|
Automation triggers:
|
|
|
|
- **on_turn_on** (*Optional*, :ref:`Action <config-action>`): An automation to perform
|
|
when the fan is turned on. See :ref:`fan-on_turn_on_off_trigger`.
|
|
- **on_turn_off** (*Optional*, :ref:`Action <config-action>`): An automation to perform
|
|
when the fan is turned off. See :ref:`fan-on_turn_on_off_trigger`.
|
|
- **on_speed_set** (*Optional*, :ref:`Action <config-action>`): An automation to perform
|
|
when the fan speed is set/changed. See :ref:`fan-on_speed_set_trigger`.

|
|
----------------------------------------
|
|
|
|
This :ref:`condition <config-condition>` passes if the given fan is on/off.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# in a trigger:
|
|
on_...:
|
|
if:

.. _fan-on_turn_on_off_trigger:
|
|
|
|
``fan.on_turn_on`` / ``fan.on_turn_off`` Trigger
|
|
------------------------------------------------
|
|
|
|
This trigger is activated each time the fan is turned on or off. It does not fire
|
|
if a command to turn the fan on or off already matches the current state.
|
|
|
|
.. code-block:: yaml
|
|
|
|
fan:
|
|
- platform: speed # or any other platform
|
|
# ...
|
|
on_turn_on:

|
|
- logger.log: "Fan Turned Off!"
|
|
|
|
.. _fan-on_speed_set_trigger:
|
|
|
|
``fan.on_speed_set`` Trigger
|
|
----------------------------
|
|
|
|
This trigger is activated each time the fan speed is changed. It will fire when the speed is either set via API e.g. in Home Assistant or locally by an automation or a lambda function.
|
|
|
|
.. code-block:: yaml
|
|
|
|
fan:
|
|
- platform: speed # or any other platform
|
|
# ...
|
|
on_speed_set:
|
|
- logger.log: "Fan Speed was changed!"
|
|
|
|
Lambda calls
|
|
------------
|
|
|
|
From :ref:`lambdas <config-lambda>`, you can call several methods on all fans to do some
|
|
advanced stuff (see the full API Reference for more info).
|
|
|
|
- ``state``: Retrieve the current state (on/off) of the fan.
|
|
|
|
.. code-block:: yaml
|
|
|
|
// Within lambda, get the fan state and conditionally do something
|
|
if (id(my_fan).state) {
|
|
// Fan is ON, do something here
|
|
} else {
|
|
// Fan is OFF, do something else here
|
|
}
|
|
|
|
- ``speed``: Retrieve the current speed of the fan.
|
|
|
|
.. code-block:: yaml
|
|
|
|
// Within lambda, get the fan speed and conditionally do something
|
|
if (id(my_fan).speed == 2) {
|
|
// Fan speed is 2, do something here
|
|
} else {
|
|
// Fan speed is not 2, do something else here
|
|
}
|
|
|
|
- ``oscillating``: Retrieve the current oscillating state of the fan.
|
|
|
|
.. code-block:: yaml
|
|
|
|
// Within lambda, get the fan oscillating state and conditionally do something
|
|
if (id(my_fan).oscillating) {
|
|
// Fan is oscillating, do something here
|
|
} else {
|
|
// Fan is not oscillating, do something else here
|
|
}
|
|
|
|
- ``direction``: Retrieve the current direction of the fan.
|
|
|
|
.. code-block:: yaml
|
|
|
|
// Within lambda, get the fan direction and conditionally do something
|
|
if (id(my_fan).direction == FanDirection::FAN_DIRECTION_FORWARD) {
|
|
// Fan direction is forward, do something here
|
|
} else {
|
|
// Fan direction is reverse, do something else here
|
|
}
|
|
|
|
- ``turn_off()``/``turn_on()``/``toggle()``: Manually turn the fan ON/OFF from code.
|
|
Similar to the ``fan.turn_on``, ``fan.turn_off``, and ``fan.toggle`` actions,
|
|
but can be used in complex lambda expressions.
|
|
|
|
.. code-block:: yaml
|
|
|
|
// Turn the fan off
|
|
auto call = id(my_fan).turn_off();
|
|
call.perform();
|
|
|
|
// Turn the fan on and set the speed, oscillating, and direction
|
|
auto call = id(my_fan).turn_on();
|
|
call.set_speed(2);
|
|
call.set_oscillating(true);
|
|
call.set_direction(FanDirection::FAN_DIRECTION_REVERSE);
|
|
call.perform();
|
|
|
|
// Toggle the fan on/off
|
|
auto call = id(my_fan).toggle();
|
|
call.perform();
|
