Thank you very much,
I already read the whole Getting Started Section, Very instructive.

One of my many doubts was about the controller, I can already read de debug through the Debug and serial monitor (easy to understand) so I was wondering why I would need them.. Ty for the awnser!

I kind of understood the Node IP adress thing. I mean, I saw a few videos on youtube using the MySensors but I'm not entirely familiar with the library.

Perhaps you know the Mysensors.h set of instructions and maybe and example of the program

Again, thank you very much and I promess you, once I finish, to donate a small amount, buy a few thing in the store and put my whole project into the forum!
