:description: Instructions for setting up a Status LED shared also as binary ON/OFF light in ESPHome.

|
|
|
|
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).
|
|
This is useful for devices with only one LED available.
|
|
|
|
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: GPIO2
|
|
|
|
.. 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.
|
|
|
|
The only difference is that the platform won't be loaded in OTA safe mode, while the component would be.
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **name** (**Required**, string): The name of the light.
|
|
- **pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The GPIO pin to operate the LED on.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- **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>`.
