core: Airthings Wave+ not detected and can't be added after deleting device

The problem

Thanks much for finally making a native integration for Airthings!

I have an rpi 3b and I’m using home assistant container.

I first got my Airthings BLE integration working immediately after upgrading Raspbian OS from buster to bullseye. It even auto detected my Wave+ correctly and everything was fine but then after a reboot the device was disconnected and sensor data was no longer updating.

I went back to the integration instructions and realized I had forgotten to switch from dbus to dbus-broker. I thought maybe Bluetooth is being unreliable because of it so I went ahead and installed dbus-broker and enabled it.

Unfortunately, even after several reboots, Airthings Wave+ was still showing disconnected. So I deleted my Airthings Wave+ device and restarted home assistant.

Now it neither auto detects it, nor can I add it manually. If I try to add it manually I get the spinner for the config flow for a while and then finally an error message “Config flow could not be loaded: Unknown error”
