The ``status_led`` hooks into all ESPHome components and can indicate the status of
2018-06-13 22:38:49 +02:00
the device. Specifically, it will:
- Blink slowly (about every second) when a **warning** is active. Warnings are active when for
example reading a sensor value fails temporarily or the WiFi/MQTT connections are disrupted.
- Blink quickly (multiple times per second) when an **error** is active. Errors indicate that
2019-02-16 23:25:23 +01:00
ESPHome has found an error while setting up. In most cases, ESPHome will still try to
2018-06-13 22:38:49 +02:00
recover from the error and continue with all other operations.
- Stay off otherwise.

# Example configuration entry
status_led:
pin: GPIO2

.. note::
If your device has a single led that needs to be shared use :doc:`status_led light platform </components/light/status_led>` instead.

Configuration variables:
------------------------
- **pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The
GPIO pin to operate the status LED on.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
.. note::
If your LED is in an active-LOW mode (when it's on if the output is enabled), use the
``inverted`` option of the :ref:`Pin Schema <config-pin_schema>`:
.. code-block:: yaml
2018-06-13 22:38:49 +02:00
status_led:
pin:
number: D0
inverted: true
