KNX2, how to set it up?

Abandoned OH2 a while ago for various reasons and now trying to get it working again.
Raspberry Pi 3
Raspbian GNU/Linux 8 (jessie)
openHAB 2.3.0~20180331153334-1 (Build #1246)

I tried to get the KNX2 binding working for 2 days now but without success.
First installed the binding using the paperui.
Then I searched for the KNX.cfg file in the Services folder but it wasn’t there.
The knx.things example seems to start with the configuration of the gateway device (I’m using an EIBMARKT KNX/EIB IP Router) so I just replaced the numbers there.

Used the “Full Example” from the KNX Binding information page as an example and was expecting Frontail to show some KNX traffic but it doesn’t…
The Things file I use:

Bridge knx:ip:bridge [
    ipAddress="192.168.1.110",
    portNumber=3671,
    localIp="192.168.1.114",
    type="TUNNEL",
    readingPause=50,
    responseTimeout=10,
    readRetriesLimit=5,
    autoReconnectPeriod=3,
    localSourceAddr="1.0.0"
] {
    Thing 1-1-45 [
        address="1.1.45"
    ]{
    /* Temperatuur sensors */
        /* Woonkamer */
        Type number :   KNX_Temp_Woonkamer_1L               "Temperature"   [ ga="9.001:<4/1/0" ]   /* Temp_Woonkamer_1L */
    }   
}

The Items file I use:

/* Woonkamer */
Number  KNX_Temp_Woonkamer_1L               "Temperature [%.1f °C]" <temperature>   { channel="knx:device:bridge:1-1-45:KNX_Temp_Woonkamer_1L" }

1.1.45 is the individual address of a Gira TS3 tastsensor and 4.1.0 is the group address linked to the internal temperature object which is being transmitted every minute.

Should be “Thing device 1-1-45 [”
Now at least I get to see the sent temperature in the log!
