Control local zigbee gateway

I have Zigbee Gateway model “NAS-ZW05B0” connected via local network and have local ip address 192.168.y.x
I want to control it via openhab bindings for all the devices it contains
openhabian version 4.0.3
I find out that zigbee binding only support usb stick
help please

I think it also should work via serial over IP … search for ‘socat’ or RFC2217 …
