adding airthingwave sensors

[Vendo232]

Hi

running already Airthingswave addon in HA which reads BLE data from Radon sensors over BT. Problem is that it is cloding with BLE Monitor probably conflict over access to the BT device,

Would it be possible to add AirThingsWave sensors?

The airthingswave integration is setting up a connection with the device. This is not supported in BLE monitor at the moment. To run both blemonitor and airthingwave integration, I would recommend to use a second Bluetooth adapter, e.g. a ASUS BT400 or something else. You can set BLE monitor to use one device while the airthingswave integration can use the other.

The Airthings has official repositories for its devices:

• Wave Mini
• Wave
• Wave Plus

... and as I see, all of them use only BLE instead of connection-oriented BT.

(I think, the Wave Plus is very impressive because it can provide humidity, temperature, radon, relative atmospheric pressure, CO2 and TVOC)

Are you sure its using BLE broadcasting instead of connnection-oriented BT? For example in Wave mini I see

    def connect(self, retries=1):
        tries = 0
        while (tries < retries and self.is_connected() is False):
            tries += 1
            if self.mac_addr is None:
                self.mac_addr = self.discover()
            try:
                self._periph = btle.Peripheral(self.mac_addr)
                self._char = self._periph.getCharacteristics(uuid=self.CURR_VAL_UUID)[0]
            except Exception:
                if tries == retries:
                    raise
                else:
                    pass

Wow... sorry! In this case, the README.md files are lying a "bit":

This is a project to provide users an interface (read_waveplus.py) to read current sensor values from the Airthings Wave Plus devices using a Raspberry Pi 3 Model B over Bluetooth Low Energy (BLE).

Both types are BLE. See for some explanation this page. https://www.blemobileapps.com/ble-mobile/

BLE communication can be done as "advertising" (one-way communication, supported by BLE monitor) or as "connecting" (two-way communication, not supported by BLE monitor). But they are both BLE communication.
