Hi Barf , thanks for your response when I say non-commercial I meant non-popular since I need to be sure that they will not interfere with the equipment that will be installed in the house, which in most cases is always the brands traditionally used in automation, I take the opportunity to ask you if there is any software to generate random IR codes that I can store in my IR library, and use them when required, it is difficult to express in English I hope you understand what I am trying to tell you, thank you
