Hello, first of all, congrats, this is amazing work and im, planning on doing it, just i have a little question, i hope someone can explain it to me, im a little confused about the comunication nodes, ¿are the sensors conected in the same arduino where the rfm module is conected? thats what i understand from text and videos, but, it also shows that the two arduinos are conected by two cables via i2c, while it says the module makes the conection btewen arduinos "wireless" ¿could somemone explain this to me? ¿how come it says you only need two arduinos when diagrams show one for sensors one for wireless and one for ethernet?
