i want to make a communication to nodes which basically is a relay. I do not want to spend cost on equipping every nodes with mcu, so my idea is to make a one line wireless communication between main mcu and nodes. First idea that came to my mind is using rf 315MHz receiver on each nodes, but it would interfee each other right? So are there any solution on this? Thanks
