AirThings BLE Sensors

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:

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.
