The ``status_led`` light platform allows to share a single LED for indicating the status of
the device (when on error/warning state) or as binary light (when on OK state).
2021-09-09 00:15:06 +02:00
This is useful for devices with only one LED available.
You can also use a binary :ref:`output`.
2021-08-10 09:55:37 +02:00
It provides the combined functionality of :doc:`status_led component </components/status_led>` and a
:doc:`binary light component </components/light/binary>` over a single shared GPIO led.

When the device is on error/warning state, the function of ``status_led`` will take precedence and control the blinking of the LED.
When the device is in OK state, the LED will be restored to the state of the ``binary light`` function and can be controlled as such.

# Example configuration entry
light:
- platform: status_led
name: "Switch state"
pin: GPIOXX
2021-08-10 09:55:37 +02:00
.. note::
When using this platform the high level ``status_led`` component should not be included (at least over the same pin),
as its functionality is directly provided by this platform.
2021-08-10 09:55:37 +02:00
The only difference is that the platform won't be loaded in OTA safe mode, while the component would be.
Configuration variables:
------------------------
- **name** (*Optional*, string): The name of the light.
2021-08-10 09:55:37 +02:00
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- **pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The GPIO pin to operate the LED on.
- **output** (*Optional*, :ref:`config-id`): The id of the binary :ref:`output` to use for this light.
2021-08-10 09:55:37 +02:00
- **effects** (*Optional*, list): A list of :ref:`light effects <light-effects>` to use for this light, though binary lights
only support very few of them.
- All other options from :ref:`Light <config-light>`.
.. note::
If your Status LED is in an active-LOW mode (such as with the D1 Mini ESP8266 boards), use the
``inverted`` option of the :ref:`Pin Schema <config-pin_schema>`:
.. code-block:: yaml
2022-01-27 00:41:36 +01:00
pin:
number: GPIOXX
2022-01-27 00:41:36 +01:00
inverted: true
