The ``ble_rssi`` sensor platform lets you track the RSSI value or signal strength of a
BLE device. See :ref:`the binary sensor setup <esp32_ble_tracker-setting_up_devices>` for
instructions for setting up this platform.

.. code-block:: yaml

    # Example configuration entry
    esp32_ble_tracker:

    sensor:
      # RSSI based on MAC address
      - platform: ble_rssi
        mac_address: AC:37:43:77:5F:4C
        name: "BLE Google Home Mini RSSI value"
      # RSSI based on Service UUID
      - platform: ble_rssi
        service_uuid: '11aa'
        name: "BLE Test Service 16 bit RSSI value"

.. note::

    Service UUID can be 16 bit long, as in the example, but it can also be 32 bit long
    like `1122aaff`, or 128 bit long like `11223344-5566-7788-99aa-bbccddeeff00`.

Configuration variables:
------------------------

- **name** (**Required**, string): The name of the sensor.
- **mac_address** (*Optional*, MAC Address): The MAC address to track for this
  sensor. Either this or ''service_uuid'' has to be present.
- **service_uuid** (*Optional*, 16 bit, 32 bit, or 128 bit BLE Service UUID): The BLE
  Service UUID which can be tracked if the device randomizes the MAC address. Either
  this or ''mac_address'' has to be present.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- All other options from :ref:`Sensor <config-sensor>`.
