Fan Entity	Fan

A fan entity is a device that controls the different vectors of your fan such as speed, direction and oscillation. Derive entity platforms from 'homeassistant.components.fan.FanDevice'.

Properties

Properties should always only return information from memory and not do I/O (like network requests). Implement update() or async_update() to fetch data.

Name	Type	Default	Description
current_direction	str	None	Return the current direction of the fan
is_on	boolean	None	Return true if the entity is on
speed	str	None	Return the current speed. One of the values in speed_list.
speed_list	list	None	Get the list of available speeds. The allowed values are "off", "low", "medium" and "high". Use the corresponding constants SPEED_OFF, SPEED_LOW, SPEED_MEDIUM, SPEED_HIGH.
supported_features	int	0	Flag supported features

Supported Features

Constant	Description
'SUPPORT_DIRECTION'	The fan supports changing the direction.
'SUPPORT_SET_SPEED'	The fan supports setting the speed.
'SUPPORT_OSCILLATE'	The fan supports oscillation.

Methods

Set direction

Only implement this method if the flag SUPPORT_DIRECTION is set.

class FanEntity(ToggleEntity):
    # Implement one of these methods.

    def set_direction(self, direction: str) -> None:
        """Set the direction of the fan."""

    async def async_set_direction(self, direction: str) -> None:
        """Set the direction of the fan."""

Set speed

Only implement this method if the flag SUPPORT_SET_SPEED is set.

class FanEntity(ToggleEntity):
    # Implement one of these methods.

    def set_speed(self, speed: str) -> None:
        """Set the speed of the fan."""

    async def async_set_speed(self, speed: str) -> None:
        """Set the speed of the fan."""

Turn on

class FanEntity(ToggleEntity):
    # Implement one of these methods.

    def turn_on(self, speed: Optional[str] = None, **kwargs: Any) -> None:
        """Turn on the fan."""

    async def async_turn_on(self, speed: Optional[str] = None, **kwargs: Any) -> None:
        """Turn on the fan."""

Turn off

class FanEntity(ToggleEntity):
    # Implement one of these methods.

    def turn_off(self, **kwargs: Any) -> None:
        """Turn the fan off."""

    async def async_turn_off(self, **kwargs: Any) -> None:
        """Turn the fan off."""

Toggle

Optional. If not implemented will default to checking what method to call using the is_on property.

class FanEntity(ToggleEntity):
    # Implement one of these methods.

    def toggle(self, **kwargs: Any) -> None:
        """Toggle the fan."""

    async def async_toggle(self, **kwargs: Any) -> None:
        """Toggle the fan."""

Oscillate

Only implement this method if the flag SUPPORT_OSCILLATE is set.

class FanEntity(ToggleEntity):
    # Implement one of these methods.

    def oscillate(self, oscillating: bool) -> None:
        """Oscillate the fan."""

    async def async_oscillate(self, oscillating: bool) -> None:
        """Oscillate the fan."""
