Hello everyone!
It is the first time here because nowhere I can find information on how to integrate a DMX module purchased on alieexpres.
The module is DMX D12 DMX or DMX D24 DMX.

By far the easiest way to get DMX out of HA is Artnet (DMX over UDP/IP). I use this thing which is available through HACS.
You will need an additional device to convert Artnet to DMX, this is called an “Artnet node”. You can buy these (again on Aliexpress) or can DIY one with Arduino/ESP8266 for a few dollars.
LED dimmers do exist with Artnet & wifi/ethernet built in, but I would imagine they are much rarer than the DMX type you linked.
Hello again and thank you for your reply. Can I ask for information on how to make Artnet node on LAN not on wifi.
Typically I would just use this firmware but it is wifi only. Most of the artnet stuff for ESP8266 is the same.
You can still use an ESP8266 with Ethernet though, but you would have to write your own firmware. There are libraries for Ethernet UDP and DMX, all you have to write is the “glue” for a simple node.
It would be much better to extend the above firmware to use an Ethernet module, since it has a bunch of nice features built in - RDM and a web UI. That’s a bit more of an involved task, however.
