Hi @huex, welcome to the forum!
Insufficient/unstable power supply is the most common reason for NACK. What capacitor(s) are you using? What power supply are you using?
If you haven't already, see https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ for the most common problems and how to troubleshoot them.
You can also use the log parser to help interpret the logs.
