Integrations that need an instance of a `BleakScanner` should call the `bluetooth.async_get_scanner` API. This API returns a wrapper around a single `BleakScanner` that allows integrations to share without overloading the system.
```python
from homeassistant.components import bluetooth
scanner = bluetooth.async_get_scanner(hass)
