Thermostat Climate Controller

=============================

:description: Instructions for setting up Thermostat climate controllers with ESPHome.
|
||
:image: air-conditioner.svg
|
||
|
||
The ``thermostat`` climate platform allows you to control a climate control system in much the same manner as a
|
||
physical thermostat. Its operation is similar to the :doc:`Bang-Bang <bang_bang>` controller; a sensor measures a value
|
||
(the air temperature) and the controller will try to keep this value within a range defined by the set point(s). To do this,
|
||
the controller can activate devices like a heating unit and/or a cooling unit to change the value observed by the sensor.
|
||
When configured for both heating and cooling, it is essentially two :doc:`Bang-Bang <bang_bang>` controllers in one; it
|
||
differs, however, in that interaction with the thermostat component is nearly identical to that of a real thermostat.
|
||
|
||
This component can operate in one of two ways:
|
||
|
||
- **Single-point**: A single threshold (set point) is defined; cooling may be activated when the observed temperature
|
||
exceeds the set point **or** heating may be activated when the observed temperature drops below the set point; that is,
|
||
the controller can only raise the temperature or lower the temperature. It cannot do both in this mode.
|
||
|
||
- **Dual-point**: Two thresholds (set points) are defined; cooling is activated when the observed temperature exceeds the
|
||
upper set point while heating is activated when the observed temperature drops below the lower set point; in other words,
|
||
the controller is able to both raise and lower the temperature as required.
|
||
|
||
This component/controller automatically determines which mode it should operate in based on what :ref:`actions <config-action>`
|
||
are configured -- more on this in a moment. Two parameters define the set points; they are ``target_temperature_low`` and
|
||
``target_temperature_high``. In single-point mode, however, only one is used. The set point(s) may be adjusted through the
|
||
front-end user interface. The screenshot below illustrates a thermostat controller in dual-point mode, where two set points
|
||
are available.

|
||
|
||
Dual-setpoint climate UI
|
||
|
||
This component works by triggering a number of :ref:`actions <config-action>` as required to keep the observed
|
||
temperature above/below/within the target range as defined by the set point(s). In general, when the observed temperature
|
||
drops below ``target_temperature_low`` the controller will trigger the ``heat_action`` to activate heating. When the observed
|
||
temperature exceeds ``target_temperature_high`` the controller will trigger the ``cool_action`` or the ``fan_only_action``
|
||
(as determined by the climate mode) to activate cooling. When the temperature has reached a point within the desired range, the
|
||
controller will trigger the ``idle_action`` to stop heating/cooling. Please see the next section for more detail.
|
||
|
||
A number of fan control modes are built into the climate/thermostat interface in Home Assistant; this component may also be
|
||
configured to trigger :ref:`actions <config-action>` based on the entire range (at the time this document was written) of fan
|
||
modes that Home Assistant offers.

Controller Behavior and Hysteresis
|
||
----------------------------------
|
||
|
||
In addition to the set points, hysteresis values determine how far the temperature may vary from the set point value(s)
|
||
before an :ref:`action <config-action>` (cooling, heating, etc.) is triggered. They each default to 0.5 °C. They are:
|
||
|
||
- ``cool_deadband``: The minimum temperature differential (temperature above the set point) before **engaging** cooling
|
||
- ``cool_overrun``: The minimum temperature differential (cooling beyond the set point) before **disengaging** cooling
|
||
- ``heat_deadband``: The minimum temperature differential (temperature below the set point) before **engaging** heat
|
||
- ``heat_overrun``: The minimum temperature differential (heating beyond the set point) before **disengaging** heat
|
||
|
||
A question that often surfaces about this component is, "What is the expected behavior?" Let's quickly discuss
|
||
*exactly when* the configured actions are called by the controller.
|
||
|
||
Consider the low set point (the one that typically activates heating) for a moment, and assume it is set to a common room
|
||
temperature of 22 °C. Let's assume ``heat_deadband`` is set to 0.4 °C while ``heat_overrun`` is set to 0.6 °C. In this case,
|
||
the controller will allow the temperature to drop as low as the set point's value (22 °C) *minus* the ``heat_deadband``
|
||
value (0.4 °C), or 21.6 °C, before calling ``heat_action`` to activate heating.
|
||
|
||
After heating has been activated, it will remain active until the observed temperature reaches the set point (22 °C) *plus*
|
||
the ``heat_overrun`` value (0.6 °C), or 22.6 °C. Once this temperature is reached, ``idle_action`` will be called to deactivate
|
||
heating.
|
||
|
||
The same behavior applies to the high set point, although the behavior is reversed in a sense; given an upper set point of
|
||
23 °C, ``cool_deadband`` set to 0.3 °C and ``cool_overrun`` set to 0.7 °C, ``cool_action`` would be called at 23.3 °C and
|
||
``idle_action`` would not be called until the temperature is reduced to 22.3 °C.
|
||
|
||
Important Terminology
|
||
---------------------
|
||
|
||
Before we get into more configuration detail, let's take a step back and talk about the word "action"; we
|
||
need to carefully consider the context of the word in the upcoming section, as it has a double meaning and
|
||
will otherwise lead to some ambiguity.
|
||
|
||
- **ESPHome Action**: A task the ESPHome application performs as requested, such as
|
||
turning on a switch. See :ref:`Action <config-action>`.
|
||
- **Climate Action**: What the climate device is actively doing
|
||
- **Climate Mode**: What the climate device should (or should not) do
|
||
|
||
We'll call out which definition "action" we are referring to as we describe them below -- read carefully!
|
||
|
||
With respect to climate control, it is important to understand the subtle difference between the terms
|
||
"action" and "mode" as they *are not the same thing*:
|
||
|
||
Examples:
|
||
|
||
- **Heat Mode**: The climate device may heat but may **not** cool.
|
||
- **Heat Action**: The climate device is *actively distributing heated air* into the dwelling.
|
||
|
||
Got all that? Great. Let's take a closer look at some configuration.
|
||
|
||
Configuration Variables:
|
||
------------------------
|
||
|
||
The thermostat controller uses the sensor to determine whether it should heat or cool.
|
||
|
||
- **sensor** (**Required**, :ref:`config-id`): The sensor that is used to measure the current temperature.
|
||
- **humidity_sensor** (**Optional**, :ref:`config-id`): If specified, this sensor is used to measure the current humidity.
|
||
This is used for information only and does not influence temperature control.
|
||
|
||
Heating and Cooling Actions
|
||
***************************
|
||
|
||
These are triggered when the climate control **action** is changed by the thermostat controller. Here,
|
||
"action" takes on both meanings described above, as these are both climate actions *and* ESPHome
|
||
:ref:`actions <config-action>`. These should be used to activate heating, cooling, etc. devices.
|
||
|
||
- **idle_action** (**Required**, :ref:`Action <config-action>`): The action to call when
|
||
the climate device should enter its idle state (not cooling, not heating).
|
||
- **heat_action** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device should enter heating mode to increase the current temperature.
|
||
- **supplemental_heating_action** (*Optional*, :ref:`Action <config-action>`): The action
|
||
to call when the climate device should activate supplemental heating to (more aggressively)
|
||
increase the current temperature. *This action is called repeatedly at an interval defined by*
|
||
``max_heating_run_time`` *(see below).*
|
||
- **cool_action** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device should enter cooling mode to decrease the current temperature.
|
||
- **supplemental_cooling_action** (*Optional*, :ref:`Action <config-action>`): The action
|
||
to call when the climate device should activate supplemental cooling to (more aggressively)
|
||
decrease the current temperature. *This action is called repeatedly at an interval defined by*
|
||
``max_cooling_run_time`` *(see below).*
|
||
- **dry_action** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device should perform its drying (dehumidification) action. The thermostat
|
||
controller does not trigger this action; it is invoked by ``dry_mode`` (see below).
|
||
- **fan_only_action** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device should activate its fan only (but does not heat or cool). When ``fan_only_cooling``
|
||
is set to ``false``, the thermostat controller immediately triggers this action when set to
|
||
``fan_only_mode``; however, when ``fan_only_cooling`` is set to ``true``, this action is called
|
||
based on the upper target temperature (similar to ``cool_action`` above).
|
||
- All other options from :ref:`Climate <config-climate>`.
|
||
|
||
**At least one of** ``cool_action``, ``fan_only_action``, ``heat_action``, **and** ``dry_action``
|
||
**must be specified.**
|
||
|
||
If only one of ``cool_action``, ``fan_only_action``, ``heat_action``, and ``dry_action`` is specified,
|
||
the controller will configure itself to operate in single-point mode and, as such, Home Assistant will
|
||
display the single-point climate user interface for the device.
|
||
|
||
Heating and Cooling Modes
|
||
*************************
|
||
|
||
These are triggered when the climate control **mode** is changed. Note the absence of "action" in the
|
||
parameter name here -- these are still ESPHome :ref:`actions <config-action>`, however they are *not*
|
||
climate actions. Instead, they are climate *modes*. These :ref:`actions <config-action>` are useful
|
||
in that they could be used, for example, to toggle a group of LEDs on and/or off to provide a visual
|
||
indication of the current climate mode.
|
||
|
||
- **auto_mode** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device is placed into "auto" mode (it may both cool and heat as required).
|
||
- **off_mode** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device is placed into "off" mode (it is completely disabled).
|
||
- **heat_mode** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device is placed into heat mode (it may heat as required, but not cool).
|
||
- **cool_mode** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device is placed into cool mode (it may cool as required, but not heat).
|
||
- **dry_mode** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device is placed into dry mode (for dehumidification).
|
||
- **fan_only_mode** (*Optional*, :ref:`Action <config-action>`): The action to call when
|
||
the climate device is placed into fan only mode (it may not heat or cool, but will activate
|
||
its fan as needed based on the upper target temperature value).
|
||
|
||
**The above actions are not to be used to activate cooling or heating devices!**
|
||
See the previous section for those.
|
||
|
||
Fan Mode Actions
|
||
****************
|
||
|
||
These are triggered when the climate control fan mode is changed. These are ESPHome :ref:`actions <config-action>`.
|
||
These should be used to control the fan only, if available.
|
||
|
||
- **fan_mode_auto_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should be set to "auto" mode (the fan is controlled by the climate control system as required).
|
||
- **fan_mode_on_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should run continuously.
|
||
- **fan_mode_off_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should never run.
|
||
- **fan_mode_low_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should run at its minimum speed.
|
||
- **fan_mode_medium_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should run at an intermediate speed.
|
||
- **fan_mode_high_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should run at its maximum speed.
|
||
- **fan_mode_middle_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should direct its airflow at an intermediate area.
|
||
- **fan_mode_focus_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should direct its airflow at a specific area.
|
||
- **fan_mode_diffuse_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should direct its airflow over a broad area.
|
||
- **fan_mode_quiet_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should run at quiet speed.
|
||
|
||
Swing Mode Actions
|
||
******************
|
||
|
||
These are triggered when the climate control swing mode is changed. These are ESPHome :ref:`actions <config-action>`.
|
||
These should be used to control the fan only, if available.
|
||
|
||
- **swing_off_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan should
|
||
remain in a stationary position.
|
||
- **swing_horizontal_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should oscillate in a horizontal direction.
|
||
- **swing_vertical_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should oscillate in a vertical direction.
|
||
- **swing_both_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the fan
|
||
should oscillate in horizontal and vertical directions.

--------------------------------
|
||
|
||
Set Point Options/Behavior
|
||
**************************
|
||
|
||
- **set_point_minimum_differential** (*Optional*, float): For dual-point/dual-function systems, the minimum
|
||
required temperature difference between the heat and cool set points. Defaults to 0.5 °C.
|
||
- **supplemental_cooling_delta** (*Required with* ``supplemental_cooling_action``, float): When the temperature
|
||
difference between the upper set point and the current temperature exceeds this value,
|
||
``supplemental_cooling_action`` will be called immediately.
|
||
- **supplemental_heating_delta** (*Required with* ``supplemental_heating_action``, float): When the temperature
|
||
difference between the lower set point and the current temperature exceeds this value,
|
||
``supplemental_heating_action`` will be called immediately.
|
||
|

||
|
||
Presets
|
||
*******
|
||
|
||
Presets allow you to define a combination of set points, climate, fan, and swing modes that can be recalled from
|
||
the front end (Home Assistant) as a single operation for quick and easy access. This can simplify the user
|
||
experience and automation.
|
||
|
||
- **preset**: (*Optional*, list)
|
||
|
||
- **name** (*Required*, string): Name of the preset. If this is one of the *standard* presets (``eco``, ``away``,
|
||
``boost``, ``comfort``, ``home``, ``sleep``, or ``activity``) it is considered a *standard* preset. Any other
|
||
string will make the preset a *custom* preset. *Standard* and *custom* presets are functionally equivalent,
|
||
the only difference is that when switching the mode via :ref:`climate.control Action <climate-control_action>`
|
||
you will need to use the `preset` or `custom_preset` property as appropriate. The Home Assistant
|
||
`climate.set_preset_mode` service treats them identically
|
||
- **default_target_temperature_low** (*Optional*, float): The default low target temperature when switching to
|
||
this preset
|
||
- **default_target_temperature_high** (*Optional*, float): The default high target temperature when switching
|
||
to this preset.
|
||
- **mode** (*Optional*, climate mode): The mode the thermostat should switch to when this preset is activated.
|
||
If not specified, the thermostat's mode will remain unchanged when the preset is activated. One of:
|
||
|
||
- ``heat_cool``
|
||
- ``cool``
|
||
- ``heat``
|
||
- ``dry``
|
||
- ``fan_only``
|
||
- ``auto``
|
||
- **fan_mode** (*Optional*, climate fan mode): The fan mode the thermostat should switch to when this preset
|
||
is activated. If not specified, the thermostat's fan mode will remain unchanged when the preset is activated.
|
||
One of:
|
||
|
||
- ``on``
|
||
- ``off``
|
||
- ``auto``
|
||
- ``low``
|
||
- ``medium``
|
||
- ``high``
|
||
- ``middle``
|
||
- ``focus``
|
||
- ``diffuse``
|
||
- ``quiet``
|
||
- **swing_mode** (*Optional*, climate swing mode): The fan swing mode the thermostat should switch to when this
|
||
preset is activated. If not specified, the thermostat's fan swing mode will remain unchanged when the preset
|
||
is activated. One of:
|
||
|
||
- ``off``
|
||
- ``both``
|
||
- ``horizontal``
|
||
- ``vertical``

Default Preset
|
||
**************
|
||
|
||
These configuration items determine default values the thermostat controller should use when it starts.
|
||
|
||
- **default_preset** (*Optional*, string): The name of the preset to use by default. Must match a preset
|
||
as per :ref:`preset <thermostat-preset>`.
|
||
- **on_boot_restore_from**: (*Optional*, on_boot_restore_from): Controls what the thermostat will do when
|
||
it first boots. One of:
|
||
|
||
- ``memory`` (default): The thermostat will restore any settings from last time it was running.
|
||
- ``default_preset``: The thermostat will always switch to the preset specified by **default_preset**
|
||
|
||
.. note::
|
||
|
||
You can specify a ``default_preset`` and set ``on_boot_restore_from`` to ``memory``. In this mode when
|
||
the settings from last boot cannot be retrieved, for any reason, then the specified ``default_preset``
|
||
will be applied.

Additional Actions/Behavior
|
||
***************************
|
||
|
||
- **target_temperature_change_action** (*Optional*, :ref:`Action <config-action>`): The action to call when the
|
||
thermostat's target temperature(s) is/are changed.
|
||
- **startup_delay** (*Optional*, boolean): If set to ``true``, when ESPHome starts, ``min_cooling_off_time``,
|
||
``min_fanning_off_time``, and ``min_heating_off_time`` must elapse before each respective action may be invoked.
|
||
This option provides a way to prevent damage to equipment (for example) disrupted by a power interruption.
|
||
Defaults to ``false``.
|
||
- **fan_only_action_uses_fan_mode_timer** (*Optional*, boolean): If set to ``true``, the ``fan_only_action`` will
|
||
share the same delay timer used for all ``fan_mode`` actions. The minimum fan switching delay is then determined
|
||
by ``min_fan_mode_switching_time`` (see below). This is useful when ``fan_only_action`` controls the same physical
|
||
fan as the ``fan_mode`` actions, common in forced-air HVAC systems.
|
||
- **fan_only_cooling** (*Optional*, boolean): If set to ``true``, when in the ``fan_only_mode`` climate mode,
|
||
the ``fan_only_action`` will only be called when the observed temperature exceeds the upper set point plus
|
||
``cool_deadband``. When set to ``false`` (the default), ``fan_only_action`` is called immediately when
|
||
``fan_only_mode`` is activated, regardless of the current temperature or set points. Defaults to ``false``.
|
||
- **fan_with_cooling** (*Optional*, boolean): If set to ``true``, ``fan_only_action`` will be called whenever
|
||
``cool_action`` is called. This is useful for forced-air systems where the fan typically runs with cooling.
|
||
Defaults to ``false``.
|
||
- **fan_with_heating** (*Optional*, boolean): If set to ``true``, ``fan_only_action`` will be called whenever
|
||
``heat_action`` is called. This is useful for forced-air systems where the fan typically runs with heating.
|
||
Defaults to ``false``.
|
||
- **max_cooling_run_time** (*Required with* ``supplemental_cooling_action``, :ref:`config-time`): Duration after
|
||
which ``supplemental_cooling_action`` will be called when cooling is active. Note that
|
||
``supplemental_cooling_action`` will be called repeatedly at an interval defined by this parameter, as well,
|
||
enabling multiple stages of supplemental (auxiliary/emergency) cooling.
|
||
- **max_heating_run_time** (*Required with* ``supplemental_heating_action``, :ref:`config-time`): Duration after
|
||
which ``supplemental_heating_action`` will be called when heating is active. Note that
|
||
``supplemental_heating_action`` will be called repeatedly at an interval defined by this parameter, as well,
|
||
enabling multiple stages of supplemental (auxiliary/emergency) heating.
|
||
- **min_cooling_off_time** (*Required with* ``cool_action``, :ref:`config-time`): Minimum duration the cooling action
|
||
must be disengaged before it may be engaged.
|
||
- **min_cooling_run_time** (*Required with* ``cool_action``, :ref:`config-time`): Minimum duration the cooling action
|
||
must be engaged before it may be disengaged.
|
||
- **min_fanning_off_time** (*Required with* ``fan_only_action``, :ref:`config-time`): Minimum duration the fanning
|
||
action must be disengaged before it may be engaged.
|
||
- **min_fanning_run_time** (*Required with* ``fan_only_action``, :ref:`config-time`): Minimum duration the fanning
|
||
action must be engaged before it may be disengaged.
|
||
- **min_heating_off_time** (*Required with* ``heat_action``, :ref:`config-time`): Minimum duration the heating action
|
||
must be disengaged before it may be engaged.
|
||
- **min_heating_run_time** (*Required with* ``heat_action``, :ref:`config-time`): Minimum duration the heating action
|
||
must be engaged before it may be disengaged.
|
||
- **min_idle_time** (**Required**, :ref:`config-time`): Minimum duration the idle action must be active before calling
|
||
another climate action.
|
||
- **min_fan_mode_switching_time** (*Required with any* ``fan_mode`` *action*, :ref:`config-time`): Minimum duration
|
||
any given fan mode must be active before it may be changed.
|
||
|
||
Note that ``min_temperature`` and ``max_temperature`` from the base climate component are used to define
|
||
the range of allowed temperature values in the thermostat component. See :doc:`/components/climate/index`.
|
||
|
||
Hysteresis Values
|
||
*****************
|
||
|
||
- **cool_deadband** (*Optional*, float): The minimum temperature differential (temperature above the set point)
|
||
before calling the cooling :ref:`action <config-action>`. Defaults to 0.5 °C.
|
||
- **cool_overrun** (*Optional*, float): The minimum temperature differential (cooling beyond the set point)
|
||
before calling the idle :ref:`action <config-action>`. Defaults to 0.5 °C.
|
||
- **heat_deadband** (*Optional*, float): The minimum temperature differential (temperature below the set point)
|
||
before calling the heating :ref:`action <config-action>`. Defaults to 0.5 °C.
|
||
- **heat_overrun** (*Optional*, float): The minimum temperature differential (heating beyond the set point)
|
||
before calling the idle :ref:`action <config-action>`. Defaults to 0.5 °C.
|
||
|
||
.. note::
|
||
|
||
- While this platform uses the term temperature everywhere, it can also be used to regulate other values.
|
||
For example, controlling humidity is also possible with this platform.
|
||
- ``min_temperature`` and ``max_temperature`` from the base climate component are used the define the range of
|
||
adjustability and the defaults will probably not make sense for control of things like humidity. See
|
||
:doc:`/components/climate/index`.
