Integration ftLab Bluetooth Smart Geiger BSG-001

I would like to integrate the “FTLab Bluetooth Smart Geiger BSG-001” in home Assistant.
The connection with the App uses Bluetooth LTE. On the Phone it works for Example with the App “BLE-Geiger”. The device is also visible with the App “BLE Scanner”.

Is there already an existing FTLab Bluetooth Smart Geiger BSG-001
integration for this purpose? Any suggestion?
