ESP32 Bluetooth Low Energy RSSI Sensor
======================================

:description: Instructions for setting up RSSI sensors for the ESP32 BLE.
:image: bluetooth.svg
:keywords: ESP32
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"
# RSSI based on iBeacon UUID
- platform: ble_rssi
ibeacon_uuid: '68586f1e-89c2-11eb-8dcd-0242ac130003'
name: "BLE Test Service iBeacon 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. Note that exactly one of ``mac_address``, ``service_uuid`` or ``ibeacon_uuid`` must 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. Note that exactly one of
``mac_address``, ``service_uuid`` or ``ibeacon_uuid`` must be present.
- **ibeacon_uuid** (*Optional*, string): The `universally unique identifier <https://en.wikipedia.org/wiki/Universally_unique_identifier>`__
to identify the beacon that needs to be tracked. Note that exactly one of ``mac_address``,
``service_uuid`` or ``ibeacon_uuid`` must be present.
- **ibeacon_major** (*Optional*, int): The iBeacon major identifier of the beacon that needs
to be tracked. Usually used to group beacons, for example for grouping all beacons in the
same building.
- **ibeacon_minor** (*Optional*, int): The iBeacon minor identifier of the beacon that needs
to be tracked. Usually used to identify beacons within an iBeacon group.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- All other options from :ref:`Sensor <config-sensor>`.
