Hcitool not working

[Burningstone]

Hmm not so familiar with hass.io.

Did you try this suggestion from the docs:

If you can’t use hcitool or bluetoothctl but have access to an Android phone you can try BLE Scanner or similar scanner applications from the Play Store to easily find your sensor MAC address. If you are using Windows 10, try the Microsoft Bluetooth LE Explorer app from the Windows Store.
