Send directly attached sensor data through Ethernet gateway

Hi,

Doe anyone have a code example how to send sensor data through the ethernetgateway? This besides the attached nRF24L01? I have some sensors directly attached to the arduino and also want to send this data to domoticz (and vice versa to a 433mhz transmitter). I'm using an UNO R3 with W5500 ethernet chip.

Thanks!
