Issue with receiving any update from KNX Binding

hi,

i have an issue with a plain new installation (openhab2 stable from yesterday, ubuntu server).
knx binding: 2.4.0
openhab: 2.4.0

i added a thing file to connect to my KNX gatway, which is working (i can switch on/off lights, dimmers etc via my basicui/habpanel) - but i do not receive any updates on the ui if something on KNX side happening (switch etc).

my configuration for a simple Test switch/dimmer/temp:

Bridge knx:ip:bridge [
    ipAddress="192.168.1.105",
    portNumber=3671,
    localIp="192.168.1.184",
    type="TUNNEL",
    localSourceAddr="1.0.199"
] {    
    Thing device DALI_Gateway   "DALI Gateway" [
        address="1.2.50",
        fetch=false,
        pingInterval=0
    ] {
        Type dimmer             : og_office_DimmerLeft      "Light"         [switch="1/1/61+<1/4/61", position="1/3/61+<1/5/61",increaseDecrease="1/2/61"]
        Type dimmer             : og_office_DimmerRight     "Light"         [switch="1/1/60+<1/4/60", position="1/3/60+<1/5/60",increaseDecrease="1/2/60"]
    }
    Thing device OG_Office_Tastsensor_Komfort_3fach [
        address="1.2.75",
        fetch=false,
        pingInterval=0
    ] {
        Type number             : og_office_temperature     "Temperature"   [ga="9.001:<7/0/0"]
    }
    Thing device OG_54A1_Aktor [
        address="1.2.1",
        fetch=false,
        pingInterval=0
    ] {
        Type switch             : og_wc_Licht                "Light"         [ga="1/1/42+1/4/42"]
    }
}

items file

Dimmer og_office_DimmerLeft "Light Left [%]" <light> {channel="knx:device:bridge:DALI_Gateway:og_office_DimmerLeft"}
Dimmer og_office_DimmerRight "Light Right [%]" <light> {channel="knx:device:bridge:DALI_Gateway:og_office_DimmerRight"}
Number og_office_temperature "Temperatur [%.1f °C]" <temperature> {channel="knx:device:bridge:OG_Office_Tastsensor_Komfort_3fach:og_office_temperature"}
Switch og_wc_Licht  "Light" <light> {channel="knx:device:bridge:OG_54A1_Aktor:og_wc_Licht"}

all the addresses are ok, and i also switched the logging on for the KNX binding

for example, switching light via UI

13:14:14.483 [TRACE] [knx.internal.client.AbstractKNXClient] - Received a Group Write telegram from '1.2.1' to '1/4/42' with value '[0]'

as you see, i also get back a 0 from 1/4/42 which is the backchannel

if i switch now via py gira app the light, nothing happens in the openhab basicui or habpanel
log:

13:20:54.663 [TRACE] [knx.internal.client.AbstractKNXClient] - Received a Group Write telegram from '10.0.10' to '1/1/42' with value '[1]'
13:20:54.802 [TRACE] [knx.internal.client.AbstractKNXClient] - Received a Group Write telegram from '1.2.1' to '1/4/42' with value '[1]'

any idea whats wrong here ? neither of my examples with dimmer, switch or temperature are working on the KNX->openhab direction, openhab->knx working normal

hmm ok i solved it, if i remove the address definition from the device definitions, the value in openhab getting also updated for KNX -> openhab.

but it seemd it getting now updated twice, (one time hitting the button, another time from status actor status update=

for example with og_office_DimmerLeft after pressing physical button (1.2.75)

why the above rule with address=“1.2.50” is not working ?

same for the temperature sensor on the switch sensor, if i remove the “1.2.75” im getting the update processed ?

whats my error ? is there an issue with the address parameter on the knx binding ?
