XIAOMI Temp and humidity not discovered

[robygi]

Hello to everybody,
I' running openHAB 2.4.0 and I'm not able to discover my XIAOMI Temperature and Humidity sensor in openHAB.
I installed the bluetooth-binding following the instructions, but when I try to discover the device in PaperUI it is not discovered.
I got other devices, but not the XIAOMI.

My bluetooth is working:

pi@mypi:~ $ sudo hciconfig -a
hci0:   Type: Primary  Bus: UART
        BD Address: fa:ke:ad:dr:es:01  ACL MTU: 1021:8  SCO MTU: 64:1

        LMP Version: 4.1 (0x7)  Subversion: 0x2209
        Manufacturer: Broadcom Corporation (15)

Moreover my raspberry get the XIAOMI device:

pi@mypi:~ $ bluetoothctl
[NEW] Controller fa:ke:ad:dr:es:01 mypi [default]
[bluetooth]# scan on
Discovery started
[CHG] Controller fa:ke:ad:dr:es:01 Discovering: yes
[NEW] Device fa:ke:ad:dr:es:02 MJ_HT_V1
[CHG] Device fa:ke:ad:dr:es:02 ServiceData Key: ------removed-------

I can use gatttool to get notifications from the device.

When we come to openHAB the XIAOMI is not discovered.

What am I doing in the wrong way?
TIA
