Read KNX value in Scripting

[Laudi111]

Hi,
i‘m new in Tasmota Scripting and need some help to read a KNX value in Scripting and write it into a variable.
I tried various expressions but nothing seems to work.
If the variable comes from the KNX bus, I get the following output in the console:

14:01:13.251 KNX: Empfangen von 6/6/10 Befehl Schreiben: 16391.46 zu KNX RX 2
14:01:13.258 RSL: RESULT = {"Command":"Unknown","Input":"EVENT KNXRX_VAL2=16391.46"}
17:38:42.873 KNX: Empfangen von 6/6/11 Befehl Schreiben: 1559.97 zu KNX RX 1
17:38:42.875 SRC: Knx
17:38:42.878 CMD: Grp 0, Cmd 'EVENT', Idx 1, Len 18, Pld -99, Data 'KNXRX_VAL1=1559.97'
17:38:42.884 RSL: RESULT = {"Command":"Unknown","Input":"EVENT KNXRX_VAL1=1559.97"}

I tried the following expressions to catch the value of KNX_RX1 or 2 an from KNX_ENERGY_TOTAL.

>D
knx_rx1=0
knx_rx2=0
knx_rx3=0
knx_rx4=0
knx_rx5=0

>E
print ===event ===
;knx_rx1=KNXRX_VAL1
;knx_rx2=EVENT#KNXRX_VAL2
knx_rx5=EVENT#knxrx_val2
knx_rx2=CB#1
knx_rx3=KNXRX_Req1
knx_rx4=KNX#KNX_ENERGY_TOTAL
knx_rx1=event#knxrx_val2

print %knx_rx1%
print %knx_rx2%
print %knx_rx3%
print %knx_rx4%
print %knx_rx5%

But I always get the value 0 as output.
I use Scripting actually to read a counter, sending values to KNX and to display some values on an OLED display.
All that works great. I hope it is possible to use Scripting because using Rules is actually not possible for me to use.

Thanks.

Hi,
unfortunately I can't get any further, who can help?
Is this function currently not implemented in Tasmota script or am I just using the wrong syntax?
Is it possible to read the KNX variables via webconsole to check if they are read in correctly?
