:description: Instructions for setting up the Tuya component.
:image: tuya.png
The ``tuya`` component creates a serial connection to the Tuya MCU for platforms to use.
.. figure:: /images/tuya.png

:width: 40%
The ``tuya`` serial component requires a :ref:`UART bus <uart>` to be configured.
Put the ``tuya`` component in the config and it will list the possible devices for you in the config log.

# Register the Tuya MCU connection

Here is an example output for a Tuya fan controller:

Configuration variables:
------------------------
- **time_id** (*Optional*, :ref:`config-id`): Some Tuya devices support obtaining local time from ESPHome.
Specify the ID of the :doc:`time/index` which will be used.
- **status_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): Some Tuya devices support WiFi status reporting ONLY through gpio pin.
Specify the pin reported in the config dump or leave empty otherwise.
More about this `here <https://developer.tuya.com/en/docs/iot/tuya-cloud-universal-serial-port-access-protocol?id=K9hhi0xxtn9cb#title-6-Query%20working%20mode>`__.
- **ignore_mcu_update_on_datapoints** (*Optional*, list): A list of datapoints to ignore MCU updates for. Useful for certain broken/erratic hardware and debugging.
Automations:
- **on_datapoint_update** (*Optional*): An automation to perform when a Tuya datapoint update is received. See :ref:`tuya-on_datapoint_update`.
Tuya Automation
---------------
.. _tuya-on_datapoint_update:
``on_datapoint_update``
***********************
This automation will be triggered when a a Tuya datapoint update is received.
A variable ``x`` is passed to the automation for use in lambdas.
The type of ``x`` variable is depending on ``datapoint_type`` configuration variable:
- *raw*: ``x`` is ``std::vector<uint8_t>``
- *string*: ``x`` is ``std::string``
- *bool*: ``x`` is ``bool``
- *int*: ``x`` is ``int``
- *uint*: ``x`` is ``uint32_t``
- *enum*: ``x`` is ``uint8_t``
- *bitmask*: ``x`` is ``uint32_t``
- *any*: ``x`` is :apistruct:`tuya::TuyaDatapoint`

}
Configuration variables:
- **sensor_datapoint** (**Required**, int): The datapoint id number of the sensor.
- **datapoint_type** (**Required**, string): The datapoint type one of *raw*, *string*, *bool*, *int*, *uint*, *enum*, *bitmask* or *any*.
