Climate

The climate integration allows you to control and monitor HVAC (heating, ventilating, and air conditioning) devices and thermostats.

Building block integration

The climate integration cannot be directly used. You cannot create your own climate entities using this integration. This integration is a building block for other integrations to use, enabling them to create climate entities for you.

Services

Climate control services

Available services: 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.turn_on, climate.turn_off

Not all climate services may be available for your platform. You can check which climate services are available under Developer Tools -> Services.

Service climate.set_aux_heat

Turn auxiliary heater on/off for climate device

Service 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:
  trigger:
    platform: time
    at: "07:15:00"
  action:
    - service: climate.set_aux_heat
      target:
        entity_id: climate.kitchen
      data:
        aux_heat: true

Service climate.set_preset_mode

Set preset mode for climate device. Away mode changes the target temperature permanently to a temperature reflecting a situation where the climate device is set to save energy. For example, this may be used to emulate a “vacation mode.”

  trigger:
    platform: time
    at: "07:15:00"
  action:
    - service: climate.set_preset_mode
      target:
        entity_id: climate.kitchen
      data:
        preset_mode: "eco"

Service climate.set_temperature

Set target temperature of climate device

Service 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.

Attributes

The climate entity has extra attributes to represent the state of the thermostat.

Name Description
hvac_action Current state: heating / cooling / idle.
fan If the fan is currently on or off: on / off.

It depends on the thermostat you are using which states are available.
