Hello and sorry, if I gave the idea of being courteous !! sorry again
I didn't publish the code because I really don't know where to start, but now that I understand WAIT, that in MySensors and a separate thing, I also understand your example, and I thank you for helping me !!
But then again I didn't know that this WAIT, was something different from DELAY
I answer little, because I'm a little busy these days ..... But anyway for now thanks again for help
