:description: Instructions for setting up a Tuya dimmer switch.
|
|
:image: brightness-medium.svg
|
|
|
|
The ``tuya`` light platform creates a simple brightness-only light from a
|
|
tuya serial component.
|
|
|
|
.. warning::
|
|
|
|
Some of these dimmers have no way of serial flashing without destroying them.
|
|
Make sure you have some way to OTA upload configured before flashing. This means you need
|
|
to have working wifi, ota, and maybe api sections in the config.
|
|
The dimmer switch I got would hang if the logger was configured to use the serial port
|
|
which meant it was bricked until I cut it open.
|
|
|
|
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 dimmer:
|
|
|
|
.. code-block:: text
|
|
|
|
[21:50:28][C][tuya:024]: Tuya:
|
|
[21:50:28][C][tuya:031]: Datapoint 3: int value (value: 139)
|
|
[21:50:28][C][tuya:029]: Datapoint 1: switch (value: OFF)
|
|
|
|
On this dimmer, the toggle switch is datapoint 1 and the dimmer value is datapoint 3.
|
|
Now you can create the light.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Create a light using the dimmer
|
|
light:
|
|
- platform: "tuya"
|
|
name: "dim1"
|
|
dimmer_datapoint: 3
|
|
min_value_datapoint: 2
|
|
switch_datapoint: 1
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- **name** (**Required**, string): The name of the light.
|
|
- **dimmer_datapoint** (*Optional*, int): The datapoint id number of the dimmer value.
|
|
- **min_value_datapoint** (*Optional*, int): The datapoint id number of the MCU minimum value
|
|
setting. If this is set then ESPHome will sync the **min_value** to the MCU on startup.
|
|
- **switch_datapoint** (*Optional*, int): The datapoint id number of the power switch. My dimmer
|
|
required this to be able to turn the light on and off. Without this you would only be able to
|
|
change the brightness and would have to toggle the light using the physical buttons.
|
|
- **color_temperature_datapoint** (*Optional*, int): The datapoint id number of the color
|
|
temperature value.
|
|
- **rgb_datapoint** (*Optional*, int): The datapoint id number of the RGB (red/green/blue) value.
|
|
If this is set then ESPHome will set the color using a 6 digit hex RGB value.
|
|
- **hsv_datapoint** (*Optional*, int): The datapoint id number of the HSV (hue/saturation/value) value.
|
|
If this is set then ESPHome will set the color using a 12 digit hex HSV value.
|
|
- **min_value** (*Optional*, int): The lowest dimmer value allowed. My dimmer had a
|
|
minimum of 25 and wouldn't even accept anything lower, but this option is available if necessary.
|
|
Defaults to 0.
|
|
- **max_value** (*Optional*, int): The highest dimmer value allowed. Most dimmers have a
|
|
maximum of 255, but dimmers with a maximum of 1000 can also be found. Try what works best.
|
|
Defaults to 255.
|
|
- **color_temperature_max_value** (*Optional*, int): The highest color temperature
|
|
value allowed. Some ceiling fans have a value of 100 (also for ``max_value``). Defaults to 255.
|
|
- **color_temperature_invert** (*Optional*, boolean): Control how color temperature values are
|
|
sent to the MCU. If this is set to true ESPHome will treat 0 as warm white and
|
|
**color_temperature_max_value** as cool white when setting **color_temperature_datapoint**.
|
|
Defaults to false.
|
|
- **cold_white_color_temperature** (*Optional*, float): The color temperature (in `mireds
|
|
<https://en.wikipedia.org/wiki/Mired>`__ or Kelvin) of the cold white channel.
|
|
- **warm_white_color_temperature** (*Optional*, float): The color temperature (in `mireds
|
|
<https://en.wikipedia.org/wiki/Mired>`__ or Kelvin) of the warm white channel.
|
|
- All other options from :ref:`Light <config-light>`.
|
|
- At least one of *dimmer_datapoint*, *switch_datapoint*, *rgb_datapoint*, or *hsv_datapoint* must be provided.
|
|
- Only one of *rgb_datapoint* or *hsv_datapoint* can be provided for one light.
|
|
|
|
.. note::
|
|
|
|
The MCU on the Tuya dimmer handles transitions and gamma correction on its own.
|
|
Therefore the ``gamma_correct`` setting default is ``1.0`` and the
|
|
``default_transition_length`` parameter is ``0s`` by default.
