How can I Command my KNX light with Basicui interface

Hello everybody,
When I switch on manually my light, on basicUI light switch on, but when in basicUI I switch on/off the light, physically nothing happen.
my Item definition :
Switch Led “LED” (Lights) {autoupdate=“true”, knx=“1.001:0/0/1”}
in my sitemap I have:
Switch item=Led icon="light"
my knx Binding is :
binding-knx1 - 1.10.0
my version of openhab is:
openhab 2.1.0 release build
I have to tell that knxtool groupswrite ip:localhost 0/0/1 1 works and light on my device.
I have an install made of a raspberry pi zero connected on a Zennio USB interface

I don’t know where is the problem, KNX binding seems working.
Can someone give me some help please?
if more information needed let me know.
