Hi electrik,
Yes, my nodes send the sketch name within the presentation function.
As for the gateway, I have not set up a sketch name, the example I found did not implement this, so I didn't think it
was necessary?
I manually named the gateway node in the configuration.yaml file, and the "missing sketch name" message no longer appears in the log. I guess, I'll add an entry for node 0 (controller) as well .
I'm still getting the "USB0 not ready after 15.0 secs" at startup, but all seems to work regardless.
I connected the gateway to my pc using mycontroller, it all works fine. Logs look normal.
Here is the code for one of my nodes, a temperature node with Arduino mini & RFM69 radio, running on battery.

I usually set up my pi by Ansible, but it's very slow. I was thinking about ways to speed that up.
