Bluetooth devices can be added today and if in the library will be discovered, if they aren't in the library just go into Settings -> Integrations -> Battery Notes screen add a new device where you can enter the battery details manually.

If you want to add to the library, just copy the manufacturer/model from the device info and create a pull request as detailed in the readme.

OK. Then I ask otherwise.
Those two sensors are using the BTHome integration.
The information displayed doesn't match, what is displayed in your documentation. Maybe it is not even possible to add information for automatic configuration at the moment for such devices.
I added the information manually anyway.

I've not seen bluetooth devices showing like this and I don't have any to test.
You are right, they will have to be added manually.
