    :description: Instructions for setting up AirThings bluetooth-based sensors in ESPHome.
    :keywords: AirThings, BLE, Bluetooth, Wave Plus

The ``airthings_wave_plus`` sensor platform lets you track the output of AirThings Bluetooth Low Energy devices.

This component will track radon, airborne chemicals, CO2, temperature and humidity and others depending on the device sensors.

Device Discovery
-----------------

AirThings devices can be found using the ``airthings_ble`` ble scanner.

To find out your device's MAC address, add the following to your ESPHome configuration:

.. code-block:: yaml

    logger:
      level: DEBUG # Required for the tracker to show the device

    esp32_ble_tracker:
    airthings_ble:

The device will then listen for nearby devices, and display a message like this one:

``
[D][airthings_ble:019]: 
Found AirThings device Serial: 123456789 (MAC: 01:02:03:04:05:06)
``

Once the device is found, **remove the ``airthings_ble:`` device tracker** from your configuration and take note of the device MAC address, and use it when configuring a sensor below.

Supported Devices

          name: "WavePlus Humidity"
        co2:
          name: "WavePlus CO2"
        tvoc:
          name: "WavePlus VOC"

    ble_client:
      - mac_address: 01:02:03:04:05:06
        id: airthings01

    esp32_ble_tracker:

.. note::

    The sensor uses active polling of devices every 5 minutes as per the device reported internal refresh timeout.
