:description: Instructions for setting up status LEDs in ESPHome to monitor the status of an ESP.

|
|
The ``status_led`` hooks into all ESPHome components and can indicate the status of
|
|
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, the WiFi/MQTT connections are disrupted, or
|
|
if the native API component is included but no client is connected.
|
|
- Blink quickly (multiple times per second) when an **error** is active. Errors indicate that
|
|
ESPHome has found an error while setting up. In most cases, ESPHome will still try to
|
|
recover from the error and continue with all other operations.
|
|
- Stay off otherwise.

# Example configuration entry
|
|
status_led:
|
|
pin: GPIOXX
|
|
|
|
.. 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
|
|
|
|
status_led:
|
|
pin:
|
|
number: GPIOXX
|
|
inverted: true
|
|
|
