Climate

The Climate integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] allows you to control and monitor HVAC (heating, ventilating, and air conditioning) devices and thermostats.

Note

Building block integration

This climate is a building block integration that cannot be added to your Home Assistant directly but is used and provided by other integrations.

A building block integration differs from the typical integration that connects to a device or service. Instead, other integrations that do integrate a device or service into Home Assistant use this climate building block to provide entities, services, and other functionality that you can use in your automations or dashboards.

If one of your integrations features this building block, this page documents the functionality the climate building block offers.

The state of an HVAC entity

An HVAC entity can have the following states, depending on the specific climate device and its capabilities.

Off: The device is turned off.
Heat: The device is set to heat to a target temperature.
Cool: The device is set to cool to a target temperature.
Heat/Cool: The device is set to heat/cool to a target temperature range.
Auto: The device is set to a schedule, learned behavior, AI.
Dry: The device is set to dry/humidity mode.
Fan only: The device only has the fan on. No heating or cooling is taking place.
Unavailable: The entity is currently unavailable.
Unknown: The state is not yet known.

Actions

Climate control actions

Available actions: climate.set_aux_heat, climate.set_preset_mode, climate.set_temperature, climate.set_humidity, climate.set_fan_mode, climate.set_hvac_mode, climate.set_swing_mode, climate.set_swing_horizontal_mode, climate.turn_on, climate.turn_off, climate.toggle

Tip

Not all climate actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] may be available for your platform. You can check which climate action are available under Developer Tools -> Actions.

Action climate.set_aux_heat

Turn auxiliary heater on/off for climate device

Data attribute	Optional	Description
`entity_id`	yes	String or list of strings that define the entity ID(s) of climate device(s) to control. To target all climate devices, use `all`.
`aux_heat`	no	New value of auxiliary heater.

Automation example

automation:
  triggers:
    - trigger: time
      at: "07:15:00"
  actions:
    - action: climate.set_aux_heat

Action climate.set_temperature

Set target temperature of climate device

Data attribute	Optional	Description
`entity_id`	yes	String or list of strings that define the entity ID(s) of climate device(s) to control. To target all climate devices, use `all`.
`temperature`	yes	New target temperature for climate device (commonly referred to as a setpoint). Do not use if `hvac_mode` is `heat_cool`.
`target_temp_high`	yes	The highest temperature that the climate device will allow. Required if `hvac_mode` is `heat_cool`. Required together with `target_temp_low`.
`target_temp_low`	yes	The lowest temperature that the climate device will allow. Required if `hvac_mode` is `heat_cool`. Required together with `target_temp_high`.
`hvac_mode`	yes	HVAC mode to set the climate device to. This defaults to current HVAC mode if not set, or set incorrectly.
