Climate Component
=================
.. seo::
:description: Information about the base representation of all climate devices.
:image: folder-open.svg
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.
.. _config-climate:
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.
.. code-block:: yaml
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:
- **id** (*Optional*, string): Manually specify the ID for code generation. At least one of **id** and **name** must be specified.
- **name** (*Optional*, string): The name of the climate device. At least one of **id** and **name** must be specified.
.. note::
If you have a :ref:`friendly_name <esphome-configuration_variables>` 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).
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.
Set to ``""`` to remove the default entity category.
- If Webserver enabled and version 3 is selected, All other options from Webserver Component.. See :ref:`Webserver Version 3 <config-webserver-version-3-options>`.
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

Climate Automation
------------------
.. _climate-control_action:
``climate.control`` Action

This is an :ref:`Action <config-action>` for setting parameters for climate devices.
.. code-block:: yaml
- climate.control:
id: my_climate

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.

.. _climate-lambda_calls:
lambda calls
************
From :ref:`lambdas <config-lambda>`, 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.
.. code-block:: cpp
// 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
.. code-block:: cpp
auto call = id(my_climate).make_call();
call.set_mode("OFF");
// etc. see API reference
call.perform();
.. _climate-on_state_trigger:
``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``.
.. code-block:: yaml
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:
``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.
.. code-block:: yaml
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);
}
