|
The ``tuya`` climate platform creates a climate device from a tuya component.
|
|
|
|
Tuya climate requires a :doc:`/components/tuya` to be configured.

On this controller (BAC-002-ELW), the data points are:
|
|
|
|
- 1 represents the climate on/off state.
|
|
- 2 represents the target temperature.
|
|
- 3 represents the current temperature.
|
|
- 4 represents the schedule mode but is not yet available to be used in ESPHome.
|
|
- 5 represents the ECO mode switch.
|
|
- 6 represents the child lock switch. (use the :doc:`/components/switch/tuya` component to control this)
|
|
- 102 represents the HVAC mode (heating, cooling, fan-only, etc.).
|
|
- 103 represents the fan speed (auto, low, medium, high, etc.).
|
|
|
|
Based on this, you can create the climate device as follows:

|
|
- **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.

|
|
|
|

|
|

|
|
|
|
- All other options from :ref:`Climate <config-climate>`.

Active state detection
|
|
----------------------
|
|
|
|
Some Tuya climate devices don't have a data point for setting and reporting HVAC mode, they use a data point to report their active state (current action). In this case, you can just use the **active_state** configuration.
|
|
|
|
If your device uses a data point for HVAC mode, but not for reporting the active state, 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 active 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.
