:description: Instructions for setting up a Tuya cover motor.
|
|
|
|
The ``tuya`` cover platform creates a simple position-only cover from a
|
|
tuya serial component.
|
|
|
|
This requires the :doc:`/components/tuya` component to be set up before you can use this platform.
|
|
|
|
Here is an example output for a Tuya M515EGWT (motor for chain roller blinds):
|
|
|
|
.. code-block:: text
|
|
|
|
[21:50:28][C][tuya:024]: Tuya:
|
|
[21:50:28][C][tuya:031]: Datapoint 2: int value (value: 53)
|
|
[21:50:28][C][tuya:029]: Datapoint 5: switch (value: OFF)
|
|
|
|
On this cover motor, the position control is datapoint 2.
|
|
Now you can create the cover.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Create a cover using the datapoint from above
|
|
cover:
|
|
- platform: "tuya"
|
|
name: "motor1"
|
|
position_datapoint: 2
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- **name** (**Required**, string): The name of the cover.
|
|
- **control_datapoint** (*Optional*, int): The datapoint id number for sending control commands.
|
|
- **position_datapoint** (**Required**, int): The datapoint id number of the cover position value.
|
|
- **position_report_datapoint** (*Optional*, int): The datapoint id number of the cover position report value, if separate from position_datapoint.
|
|
- **direction_datapoint** (*Optional*, int): The datapoint id number for setting the direction of travel.
|
|
- **min_value** (*Optional*, int): The lowest position value, meaning cover closed. Defaults to 0.
|
|
- **max_value** (*Optional*, int): the highest position value, meaning cover opened. Defaults to 255.
|
|
- **invert_position** (*Optional*, boolean): Sets the direction of travel to be inverted, if direction_datapoint is configured.
|
|
- **invert_position_report** (*Optional*, boolean): Invert reported position percentages calculated from `min_value` and `max_value` i.e. 70% becomes 30%. Defaults to false.
|
|
- All other options from :ref:`Cover <config-cover>`.
|
|
|
|
Supported devices
|
|
-----------------
|
|
|
|
Tuya cover devices known to be supported by this component:
|
|
|
|
- Tuya ``M515EGWT`` (motor for bead chain roller blinds)
|
|
|
|
- Only the ``position`` datapoint (2) is used for this device.
|
|
- Datapoint 5's function is not currently known.
|
|
|
|
- Zemismart ``ZM79E-DT`` and ``YH002`` (curtain motor)
|
|
|
|
- Supported datapoints: ``control`` (1), ``position`` (2), ``position_report`` (3) and ``direction`` (5).
|
|
- The direction of travel is persisted to the Tuya MCU, so doesn't need to be set if you've already configured it via the remote control.
|
|
|
|
If you have a Tuya cover device that isn't listed above, it may still work - but you'll need to determine which datapoints it uses
|
|
(and what their IDs are) for yourself.
|
|
|
|
Restore modes
|
|
-------------
|
|
|
|
The default restore mode (``RESTORE``) attempts to restore the state on startup, but doesn't instruct the cover to move to that state.
|
|
|
|
``RESTORE_AND_CALL`` additionally instructs the cover to move to the restored state - which might not work, depending on your device (see note below).
|
|
|
|
The Tuya MCU usually reports its position on startup, so ``NO_RESTORE`` will likely also appear to restore its state - but may take slightly longer.
|
|
|
|
Note that if your Tuya cover device uses relative position sensing (such as the ZM79E-DT), it can't tell if the cover was moved while not powered up.
|
|
This means that moving the cover while the device is powered off will result in its position not matching the reported/requested state.
|
|
In this condition, it will go into an error / uncalibrated state when it next tries to go in one direction (as it can't move as far as it wants to), requiring an open/close cycle to recalibrate.
