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.

Base Climate Configuration

All climate platforms in ESPHome inherit from the climate configuration schema.

climate:
  - platform: ...
    visual:
      min_temperature: 18 °C
      max_temperature: 25 °C
      temperature_step: 0.1 °C

Configuration variables:

  • 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.

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.

  • If MQTT enabled, all other options from MQTT Component.

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.

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

  • away (Optional, boolean, templatable): Set the away mode of the climate device.

  • preset (Optional, string, templatable): Set the preset of the climate device. One of ECO, AWAY, BOOST, COMFORT, HOME, SLEEP, ACTIVITY.

  • custom_preset (Optional, string, templatable): Set one of the supported custom_presets of the climate device.

  • fan_mode (Optional, string, templatable): Set the fan mode of the climate device. One of ON, OFF, AUTO, LOW, MEDIUM, HIGH, MIDDLE, FOCUS, DIFFUSE.

  • custom_fan_mode (Optional, string, templatable): Set one of the supported custom_fan_modes of the climate device.

  • swing_mode (Optional, string, templatable): Set the swing mode of the climate device. One of OFF, BOTH, VERTICAL, HORIZONTAL.

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
    // 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
    // Away mode, type: bool
    id(my_climate).away
    // Fan mode, type: FanMode (enum)
    id(my_climate).fan_mode
    // Swing mode, type: SwingMode (enum)
    id(my_climate).swing_mode
    
  • .make_call: Control the climate device

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