|
|
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.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Make sure logging is not using the serial port
|
|
logger:
|
|
baud_rate: 0
|
|
|
|
uart:
|
|
rx_pin: GPIO3
|
|
tx_pin: GPIO1
|
|
baud_rate: 9600

# 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 :ref:`Time Component <time>` which will be used.
|
|
|
|
- **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*.
