Control Livolo switches / Livolo switch library

Hi spch
I am following your post quite sometime after I bought livolo switch and face same problem.
It is very useful information in your post and codes are working perfectly.
What I am doing right now is, to have more codes ( I wanted around 20 codes to control 20 different switches) by doing try and error method on your codes. I have to admit that it is not successful at all. I cannot get even one more code.
Is it possible to get more codes to control livolo switches and how?

Sorry, I am very new to RF and Arduino.

Regards
