:description: Instructions for setting up a Tuya climate device.

|
|
The ``tuya`` climate platform creates a climate device from a tuya component.
|
|
|
|
The Tuya fan requires a :doc:`/components/tuya` to be configured.
|
|
|
|
.. code-block:: text
|
|
|
|
[22:03:11][C][tuya:023]: Tuya:
|
|
[22:03:11][C][tuya:032]: Datapoint 1: switch (value: ON)
|
|
[22:03:11][C][tuya:032]: Datapoint 2: switch (value: OFF)
|
|
[22:03:11][C][tuya:034]: Datapoint 3: int value (value: 20)
|
|
[22:03:11][C][tuya:034]: Datapoint 4: int value (value: 19)
|
|
[22:03:11][C][tuya:034]: Datapoint 5: int value (value: 0)
|
|
[22:03:11][C][tuya:036]: Datapoint 7: enum (value: 1)
|
|
[22:03:11][C][tuya:046]: Product: '{"p":"ynjanlglr4qa6dxf","v":"1.0.0","m":0}'
|
|
|
|
On this controller, the data points are:
|
|
|
|
- 1 represents the climate on/off state.
|
|
- 2 represents the child lock switch. (use the :doc:`/components/switch/tuya` component to control this)
|
|
- 3 represents the target temperature.
|
|
- 4 represents the current temperature.
|
|
- 5 represents the timer but is not yet available to be used in ESPHome.
|
|
- 7 represents the eco mode switch.
|
|
|
|
Based on this, you can create the climate device as follows:
|
|
|
|
.. code-block:: yaml
|
|
|
|
climate:
|
|
- platform: tuya
|
|
name: "My Climate Device"
|
|
switch_datapoint: 1
|
|
target_temperature_datapoint: 3
|
|
current_temperature_datapoint: 4
|
|
eco_datapoint: 7
|
|
eco_temperature: 20 °C
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- **name** (**Required**, string): The name of the climate device.
|
|
- **supports_heat** (*Optional*, boolean): Specifies if the device has a heating mode. Defaults to ``true``.
|
|
- **supports_cool** (*Optional*, boolean): Specifies if the device has a cooling mode. Defaults to ``false``.
|
|
- **switch_datapoint** (**Required**, int): The datapoint id number of the climate switch (device on/off).
|
|
- **active_state_datapoint** (*Optional*, int): The datapoint id number of the active state - :ref:`see below <active_state_detection>`.
|
|
- **active_state_heating_value** (*Optional*, int): The active state datapoint value the device reports when heating. Defaults to ``1`` - :ref:`see below <active_state_detection>`.
|
|
- **active_state_cooling_value** (*Optional*, int): The active state datapoint value the device reports when cooling - :ref:`see below <active_state_detection>`.
|
|
- **heating_state_pin** (*Optional*, :ref:`config-pin`): The input pin indicating that the device is heating - :ref:`see below <active_state_detection>`. Only used if **active_state_datapoint** is not configured.
|
|
- **cooling_state_pin** (*Optional*, :ref:`config-pin`): The input pin indicating that the device is cooling - :ref:`see below <active_state_detection>`. Only used if **active_state_datapoint** is not configured.
|
|
- **target_temperature_datapoint** (**Required**, int): The datapoint id number of the target temperature.
|
|
- **current_temperature_datapoint** (**Required**, int): The datapoint id number of the current temperature.
|
|
- **temperature_multiplier** (*Optional*, float): A multiplier to modify the incoming and outgoing temperature values - :ref:`see below <temperature-multiplier>`.
|
|
- **eco_datapoint** (*Optional*, int): The datapoint id number of the eco mode state.
|
|
- **eco_temperature** (*Optional*, float): The target temperature the controller uses while the eco mode is active.
|
|
|
|
If the device has different multipliers for current and target temperatures, **temperature_multiplier** can be replaced with both of:
|
|
|
|
- **current_temperature_multiplier** (*Optional*, float): A multiplier to modify the current temperature value.
|
|
- **target_temperature_multiplier** (*Optional*, float): A multiplier to modify the target temperature value.
|
|
|
|
- All other options from :ref:`Climate <config-climate>`.
|
|
|
|
.. _active_state_detection:
|
|
|
|
Active state detection
|
|
----------------------
|
|
|
|
Some Tuya climate devices report the active state (idle/heating/cooling) via a tuya data point. In this case, you can use the **active_state_datapoint** variable together with **active_state_heating_value** and **active_state_cooling_value**.
|
|
|
|
If your device does not make a data point available for this, it is possible to modify the hardware so that the relay outputs can be read by the ESP. Please refer to `this discussion <https://github.com/klausahrenberg/WThermostatBeca/issues/17>` for more details on the required modifications. You can then use the **heating_state_pin** and/or **cooling_state_pin** configuration variables to detect the current state.
|
|
|
|
If none of the above variables are set, the current state is inferred from the difference between the current and target temperatures.
|
|
If **supports_heat** is ``True`` and the current temperature is more than 1 °C below the target temperature, the device is expected to be heating.
|
|
If **supports_cool** is ``True`` and the current temperature is more than 1 °C above the target temperature, the device is expected to be cooling.
|
|
|
|
.. _temperature-multiplier:
|
|
|
|
Temperature multiplier
|
|
----------------------
|
|
|
|
Some Tuya climate devices report the temperature with a multiplied factor. This is because the MCU only utlizes
|
|
integers for data reporting and to get a .5 temperature you need to divide by 2 on the ESPHome side.
