|
|
The ``tuya`` component creates a serial connection to the Tuya MCU for platforms to use.

|
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.

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-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*.
