This should work with Domoticz, it's what I intend to use with it. I've received the boards from China and I'm currently working on a version 2 of this board. There are some errors in the design of version 1 that I need to get out. New version will be up shortly.
Wow, great! Its alway nice to see others using my work too. Your code improvement seem to be very helpful too.
I have most recently also integrated this directly into my gateway build (see here). I am still struggling with code there though.
@YuryPol as far as I know, all licenses require some form of documentation. In all cases I know of, this is documented with the license or on the licenses official site.
