:description: Instructions for setting up Improv via BLE in ESPHome.
:image: improv-social.png
The ``esp32_improv`` component in ESPHome implements the open `Improv standard <https://www.improv-wifi.com/>`__
for configuring Wi-Fi on an ESP32 device by using Bluetooth Low Energy to receive the credentials.
The ``esp32_improv`` component will automatically set up the :doc:`BLE Server <esp32_ble>`.
.. code-block:: yaml
# Example configuration entry
wifi:
# ...
esp32_improv:
authorizer: binary_sensor_id
Configuration variables:
------------------------
- **authorizer** (**Required**, :ref:`config-id`): A :doc:`binary sensor <binary_sensor/index>` to authorize with.
Also accepts ``none``/``false`` to skip authorization.
- **authorized_duration** (*Optional*, :ref:`config-time`): The amount of time until authorization times out and needs
to be re-authorized. Defaults to ``1min``.
- **status_indicator** (*Optional*, :ref:`config-id`): An :doc:`output <output/index>` to display feedback to the user.
- **identify_duration** (*Optional*, :ref:`config-time`): The amount of time to identify for. Defaults to ``10s``.
- **wifi_timeout** (*Optional*, :ref:`config-time`): The amount of time to wait before starting the improv service after Wi-Fi
is no longer connected. Defaults to ``1min``.
Status Indicator
----------------
The ``status_indicator`` has the following patterns:
- solid: The improv service is active and waiting to be authorized.
- blinking once per second: The improv service is awaiting credentials.
- blinking 3 times per second with a break in between: The identify command has been used by the client.
- blinking 5 times per second: Credentials are being verified and saved to the device.
- off: The improv service is not running.
