Climate Entity

A climate entity controls temperature, humidity, or fans, such as A/C systems and humidifiers. Derive a platform entity from homeassistant.components.climate.ClimateEntity

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

supported_features	int	`NotImplementedError()`	Bitmap of supported features. See below.

HVAC modes

You are only allowed to use the built-in HVAC modes, provided by the HVACMode enum. If you want another mode, add a preset instead.

Name	Description
`HVACMode.OFF`	The device is turned off.
`HVACMode.HEAT`	The device is set to heat to a target temperature.
`HVACMode.COOL`	The device is set to cool to a target temperature.
`HVACMode.HEAT_COOL`	The device is set to heat/cool to a target temperature range.
`HVACMode.AUTO`	The device is set to a schedule, learned behavior, AI.
`HVACMode.DRY`	The device is set to dry/humidity mode.
`HVACMode.FAN_ONLY`	The device only has the fan on. No heating or cooling taking place.

HVAC Action

The HVAC action describes the current action. This is different from the mode, because if a device is set to heat, and the target temperature is already achieved, the device will not be actively heating anymore. It is only allowed to use the built-in HVAC actions, provided by the HVACAction enum.

Name	Description
`HVACAction.OFF`	Device is turned off.
`HVACAction.HEATING`	Device is heating.
`HVACAction.COOLING`	Device is cooling.
`HVACAction.DRYING`	Device is drying.
`HVACAction.FAN`	Device has fan on.
`HVACAction.IDLE`	Device is idle.

Presets

A device can have different presets that it might want to show to the user. Common presets are "Away" or "Eco". There are a couple of built-in presets that will offer translations, but you're also allowed to add custom presets.

Name	Description
`ECO`	Device is running an energy-saving mode
`AWAY`	Device is in away mode
`BOOST`	Device turn all valve full up
`COMFORT`	Device is in comfort mode
`HOME`	Device is in home mode
`SLEEP`	Device is prepared for sleep
`ACTIVITY`	Device is reacting to activity (e.g. movement sensors)

Fan modes

A device's fan can have different states. There are a couple of built-in fan modes, but you're also allowed to use custom fan modes.

Name
`FAN_ON`
`FAN_OFF`
`FAN_AUTO`
`FAN_LOW`
`FAN_MEDIUM`
`FAN_HIGH`
`FAN_MIDDLE`
`FAN_FOCUS`
`FAN_DIFFUSE`

Swing modes

The device fan can have different swing modes that it wants the user to know about/control.

Name	Description
`SWING_OFF`	The fan is not swinging.
`SWING_ON`	The fan is swinging.
`SWING_VERTICAL`	The fan is swinging vertical.
`SWING_HORIZONTAL`	The fan is swinging horizontal.
`SWING_BOTH`	The fan is swinging both horizontal and vertical.

Supported Features

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

Value	Description
`TARGET_TEMPERATURE`	The device supports a target temperature.
`TARGET_TEMPERATURE_RANGE`	The device supports a ranged target temperature. Used for HVAC modes `heat_cool` and `auto`
`TARGET_HUMIDITY`	The device supports a target humidity.
`FAN_MODE`	The device supports fan modes.
`PRESET_MODE`	The device supports presets.
`SWING_MODE`	The device supports swing modes.
`AUX_HEAT`	The device supports auxiliary heaters.
