Sure, there is already the KiCAD file including everything to play around with on your own; added a picture of the schematic here for a quick glance without downloading.
Hi, not sure if @Floca get his nodes working, but for me, the problem got fixed with this
#define MY_RF69_IRQ_NUM MY_RF69_IRQ_PIN
as mentioned by @mfalkvidd Thanks!
I think I found the problem. I think it misbehaved because of an illegal character in the "HOSTNAME". Changed the hostname yesterday and It was still alive this morning even if I have not pinged it.
