Hi there, it was indeed permissions case - or capabilities as its called. I had to issue this command to get libpcap working on normal user:

sudo setcap cap\_net\_raw=eip /usr/bin/node

Then I could start seeing arps being captured by nodered and amazon dash button presses are now fully functional.

Thank you for point this to me.
