Humidifier entity

A humidifier entity is a device whose main purpose is to control humidity, i.e. a humidifier or dehumidifier. Derive entity platforms from homeassistant.components.humidifier.HumidifierEntity

Properties

tip

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
action	HumidifierAction | None	None	Returns the current status of the device.
available_modes	list[str] | None	Required by MODES	The available modes. Requires SUPPORT_MODES.
current_humidity	float | None	None	The current humidity measured by the device.
device_class	HumidifierDeviceClass | None	None	Type of hygrostat
is_on	bool | None	None	Whether the device is on or off.
max_humidity	float	DEFAULT_MAX_HUMIDITY (value == 100)	The maximum humidity.
min_humidity	float	DEFAULT_MIN_HUMIDITY (value == 0)	The minimum humidity.
mode	str | None	Required	The current active mode. Requires SUPPORT_MODES.
target_humidity	float | None	None	The target humidity the device is trying to reach.

Available device classes

Constant	Description
HumidifierDeviceClass.DEHUMIDIFIER	A dehumidifier
HumidifierDeviceClass.HUMIDIFIER	A humidifier

Modes

A device can have different modes of operation that it might want to show to the user. They could be viewed as presets or some device states with reduced or enhanced functionality for special conditions, i.e. "auto" or "baby". There are a couple of built-in modes that will offer translations, but you're also allowed to add custom modes if that better represents the device.

Name	Description
MODE_NORMAL	No preset is active, normal operation
MODE_ECO	Device is running an energy-saving mode
MODE_AWAY	Device is in away mode
MODE_BOOST	Device turn all valve full up
MODE_COMFORT	Device is in comfort mode
MODE_HOME	Device is in home mode
MODE_SLEEP	Device is prepared for sleep
MODE_AUTO	Device is controlling humidity by itself
MODE_BABY	Device is trying to optimize for babies

Supported features

Supported features are defined by using values in the HumidifierEntityFeature enum and are combined using the bitwise or (|) operator.

Value	Description
MODES	The device supports different modes.

Action

The action property may return the current operating state of the device, whether it is humidifying or idle. This is an informational property. Please note that when the device is off, the action attribute, if present, will automatically be replaced with "off". Also, please note that setting action to off does not replace the is_on property.

Current values for HumidifierAction:

Name	Description
HUMIDIFYING	The device is currently humidifying.
DRYING	The device is currently dehumidifying.
IDLE	The device is on but not active right now.
OFF	The device is switched off.

Methods

Set mode

class MyHumidifierEntity(HumidifierEntity):
    # Implement one of these methods.

    def set_mode(self, mode):
        """Set new target preset mode."""

    async def async_set_mode(self, mode):
        """Set new target preset mode."""

Set humidity

If the current mode does not allow to adjust target humidity, the device should automatically change its mode to the one which makes it possible upon this call.

class MyHumidifierEntity(HumidifierEntity):
    # Implement one of these methods.

    def set_humidity(self, humidity):
        """Set new target humidity."""

    async def async_set_humidity(self, humidity):
        """Set new target humidity."""

Turn on

class MyHumidifierEntity(HumidifierEntity):
    # Implement one of these methods.

    def turn_on(self, **kwargs):
        """Turn the device on."""

    async def async_turn_on(self, **kwargs):
        """Turn the device on."""

Turn off

class MyHumidifierEntity(HumidifierEntity):
    # Implement one of these methods.

    def turn_off(self, **kwargs):
        """Turn the device off."""

    async def async_turn_off(self, **kwargs):
        """Turn the device off."""
