Climate

The climate component is built for the controlling and monitoring of HVAC (heating, ventilating, and air conditioning) and thermostat devices.

To enable this component, pick one of the platforms, and add it to your configuration.yaml:

# Example configuration.yaml entry
climate:
  platform: demo

Services

Climate control services

Available services: climate.set_aux_heat, climate.set_away_mode, climate.set_temperature, climate.set_humidity, climate.set_fan_mode, climate.set_operation_mode, climate.set_swing_mode, climate.set_hold_mode, climate.turn_on, climate.turn_off

Not all climate services may be available for your platform. Be sure to check the available services Home Assistant has enabled by checking service developer tool icon 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 point at entity_id’s of climate devices to control. Else targets 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
      data:
        entity_id: climate.kitchen
        aux_heat: true

Service climate.set_away_mode

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

Service data attribute Optional Description
entity_id yes String or list of strings that point at entity_id’s of climate devices to control. Else targets all.
away_mode no New value of away mode.

Automation example

automation:
  trigger:
    platform: time
    at: "07:15:00"
  action:
    - service: climate.set_away_mode
      data:
        entity_id: climate.kitchen
        away_mode: 'on'

Service climate.set_hold_mode

Set hold mode for climate device. The hold mode changes the target temperature of the client device temporarily to a different temperature. Typical hold modes provided by a climate device are “away” or “home”, where the hold temperature is chosen depending on a predefined climate, or “temperature” hold, where a particular temperature is selected as the temporary target temperature. The particular modes available depend on the climate device.

Service data attribute Optional Description
entity_id yes String or list of strings that point at entity_id’s of climate devices to control. Else targets all.
hold_mode no New value of hold mode.

Automation example

automation:
  trigger:
    platform: time
    at: "07:15:00"
  action:
    - service: climate.set_hold_mode
      data:
        entity_id: climate.kitchen
        hold_mode: 'away'

Service climate.set_temperature

Set target temperature of climate device

Service data attribute Optional Description
entity_id yes String or list of strings that point at entity_id’s of climate devices to control. Else targets all.
temperature no New target temperature for hvac
target_temp_high yes New target high temperature for hvac
target_temp_low yes New target low temperature for hvac
operation_mode yes Operation mode to set temperature to. This defaults to current_operation mode if not set, or set incorrectly.

Automation example

automation:
  trigger:
    platform: time
    at: "07:15:00"
  action:
    - service: climate.set_temperature
      data:
        entity_id: climate.kitchen
        temperature: 24
        operation_mode: Heat

Service climate.set_humidity

Set target humidity of climate device

Service data attribute Optional Description
entity_id yes String or list of strings that point at entity_id’s of climate devices to control. Else targets all.
humidity no New target humidity for climate device

Automation example

automation:
  trigger:
    platform: time
    at: "07:15:00"
  action:
    - service: climate.set_humidity
      data:
        entity_id: climate.kitchen
        humidity: 60

Service climate.set_fan_mode

Set fan operation for climate device

Service data attribute Optional Description
entity_id yes String or list of strings that point at entity_id’s of climate devices to control. Else targets all.
fan_mode no New value of fan mode

Automation example

automation:
  trigger:
    platform: time
    at: "07:15:00"
  action:
    - service: climate.set_fan_mode
      data:
        entity_id: climate.kitchen
        fan_mode: 'On Low'

Service climate.set_operation_mode

Set operation mode for climate device

Service data attribute Optional Description
entity_id yes String or list of strings that point at entity_id’s of climate devices to control. Else targets all.
operation_mode no New value of operation mode

Automation example

automation:
  trigger:
    platform: time
    at: "07:15:00"
  action:
    - service: climate.set_operation_mode
      data:
        entity_id: climate.kitchen
        operation_mode: Heat

Service climate.set_swing_mode

Set operation mode for climate device

Service data attribute Optional Description
entity_id yes String or list of strings that point at entity_id’s of climate devices to control. Else targets all.
swing_mode no New value of swing mode

Automation example

automation:
  trigger:
    platform: time
    at: "07:15:00"
  action:

entity_id yes String or list of strings that point at entity_id’s of climate devices to control. Targets all when omitted.

Customization

The step for the setpoint can be adjusted (default to 0,5 increments) by adding the following line into configuration

customize:
  - entity_id
      target_temp_step: 1
