Climate Component

ESPHome has support for climate devices. Climate devices can represent different types of hardware, but the defining factor is that climate devices have a settable target temperature and can be put in different modes like HEAT, COOL, HEAT_COOL or OFF.

Note

Not all climate components support all possible features. Check the corresponding documentation page for details on what is supported.

Base Climate Configuration

All climate platforms in ESPHome inherit from the climate configuration schema. In ESPHome, °C is assumed for all temperature values. Some platforms allow conversion or setting in °F, this is specified separately.

climate:
  - platform: ...
    visual:
      min_temperature: 18
      max_temperature: 25
      temperature_step: 0.1
      min_humidity: 30%
      max_humidity: 99%
  - platform: ...
    visual:
      min_temperature: 18
      max_temperature: 25
      temperature_step:
        target_temperature: 0.5
        current_temperature: 0.1

Configuration variables:

  • name (Required, string): The name of the climate device.

    Note

    If you have a friendly_name set for your device and you want the climate to use that name, you can set name: None.

  • icon (Optional, icon): Manually set the icon to use for the climate device in the frontend.

  • visual (Optional): Visual settings for the climate device - these do not affect operation and are solely for controlling how the climate device shows up in the frontend.

    • min_temperature (Optional, float): The minimum temperature the climate device can reach. Used to set the range of the frontend gauge.

    • max_temperature (Optional, float): The maximum temperature the climate device can reach. Used to set the range of the frontend gauge.

    • temperature_step (Optional, float): The granularity with which the target temperature can be controlled. Can be a single number, or split as below:

      • target_temperature (Required, float): The granularity for target temperature

      • current_temperature (Required, float): The granularity for current temperature

    • min_humidity (Optional, percentage): The minimum humidity the climate device can reach. Used to set the range of the frontend gauge.

    • max_humidity (Optional, percentage): The maximum humidity the climate device can reach. Used to set the range of the frontend gauge.

Advanced options:

  • internal (Optional, boolean): Mark this component as internal. Internal components will not be exposed to the frontend (like Home Assistant). Only specifying an id without a name will implicitly set this to true.

  • disabled_by_default (Optional, boolean): If true, then this entity should not be added to any client’s frontend, (usually Home Assistant) without the user manually enabling it (via the Home Assistant UI). Requires Home Assistant 2021.9 or newer. Defaults to false.

  • entity_category (Optional, string): The category of the entity. See https://developers.home-assistant.io/docs/core/entity/#generic-properties for a list of available options. Requires Home Assistant 2021.11 or newer. Set to "" to remove the default entity category.

MQTT options:

  • action_state_topic (Optional, string): The topic to publish climate device action changes to.

  • current_temperature_state_topic (Optional, string): The topic to publish current temperature changes to.

  • current_humidity_state_topic (Optional, string): The topic to publish current humidity changes to.

  • fan_mode_state_topic (Optional, string): The topic to publish fan mode changes to.

  • fan_mode_command_topic (Optional, string): The topic to receive fan mode commands on.

  • mode_state_topic (Optional, string): The topic to publish climate device mode changes to.

  • mode_command_topic (Optional, string): The topic to receive climate device mode commands on.

  • target_temperature_high_state_topic (Optional, string): The topic to publish higher target temperature changes to.

  • target_temperature_high_command_topic (Optional, string): The topic to receive higher target temperature commands on.

  • target_temperature_low_state_topic (Optional, string): The topic to publish lower target temperature changes to.

Climate Automation

climate.control Action

This is an Action for setting parameters for climate devices.

- climate.control:
    id: my_climate
    mode: HEAT_COOL
    target_temperature: 25°C

Configuration variables:

  • id (Required, ID): The ID of the climate device to control.

  • mode (Optional, string, templatable): Put the climate device in a specific mode. One of

    • OFF - The device is manually set to off, the device is inactive.

    • AUTO - The device is should adjust the temperature dynamically. For example based on a schedule, or learned behavior.

    • HEAT - The device is set to heat to reach a target temperature.

    • COOL - The device is set to cool to reach a target temperature.

    • HEAT_COOL - The device should heat/cool to maintain a target temperature.

    • FAN_ONLY - The device only has the fan enabled, no heating or cooling is taking place.

    • DRY - The device is set to dry/humidity mode.

  • target_temperature (Optional, float, templatable): Set the target temperature of a climate device.

  • target_temperature_low (Optional, float, templatable): Set the lower target temperature of a climate device with a two-point target temperature.

lambda calls

From lambdas, you can call several methods on all binary sensors to do some advanced stuff.

  • Attributes: All climate devices have read-only attributes to get the current state of the device.

    // Current mode, type: ClimateMode (enum)
id(my_climate).mode
// Current temperature, type: float (degrees)
id(my_climate).current_temperature
// Current humidity, type: float (percentage)
id(my_climate).current_humidity
// Target temperature, type: float (degrees)
id(my_climate).target_temperature
// Lower Target temperature, type: float (degrees)
id(my_climate).target_temperature_low
// High Target temperature, type: float (degrees)
id(my_climate).target_temperature_high
// Target humidity, type: float (percentage)
id(my_climate).target_humidity
// Fan mode, type: FanMode (enum)
id(my_climate).fan_mode
// Custom Fan mode, type: string
id(my_climate).custom_fan_mode
// Swing mode, type: SwingMode (enum)
id(my_climate).swing_mode
// Current action (currentl on idle, cooling, heating, etc.), ClimateAction (enum)
id(my_climate).action
// Preset, type: Preset (enum)
id(my_climate).preset
// Custom Preset, type: string
id(my_climate).custom_preset

  • .make_call: Control the climate device

    auto call = id(my_climate).make_call();
call.set_mode("OFF");
// etc. see API reference
call.perform();

climate.on_state Trigger

This trigger is activated each time the state of the climate device is updated (for example, if the current temperature measurement or the mode set by the users changes). The Climate itself is available to automations as the reference x.

climate:
  - platform: midea  # or any other platform
    # ...
    on_state:
      - logger.log: "State updated!"
      - lambda: |-
          if (x.mode != CLIMATE_MODE_OFF)
            id(some_binary_sensor).publish_state(true);

climate.on_control Trigger

This trigger is activated each time a control input of the climate device is updated via a ClimateCall (which includes changes coming in from Home Assistant). That is, this trigger is activated for, for example, changes to the mode, but not on temperature measurements. It will be invoked prior to the on_state trigger, if both are defined. The ClimateCall control object is available to automations as the reference x that can be changed.

climate:
  - platform: ...
    # ...
    on_control:
      - logger.log: "Control input received; configuration updated!"
      - lambda: |-
          if (x.get_mode() != CLIMATE_MODE_OFF) {
              id(turnoff_script).stop();
              x.set_target_temperature(25.0f);
          }
