I think it is a Hardware Problem.
Can i send you the Spirit Pro unit and the WiFi Modul to
Check it and if possible repair?

Yes, this is not a problem.
We can fix any problem in 1 day. We will check everything and tell you where was the problem. I believe that it will be nothing too bad.
Please send everything that you wish to the address that is on the white Spirit box.

I have no white spirit box .
To which address should I send the device

That's what I meant, I was wondering if the App was thinking you have a BT adapter and trying to connect like that.

If Bluetooth is ON in the phone, the Spirit App lists the possible BT connections and not the WIFI text I wrote you above (WIFI [192.168.4.1]).
