[SOLVED] Amazon dash button: Steps for a complete setup

I have issues running the dashbuttons since upgrade to 2.5 M3.
They have worked flawlessly and I wonder what’s wrong.

I don’t even see the dash… triggered messages in the events log.

I did all the steps above, but did not succeed. :frowning:

What does this mean?

Could not get value by org.pcap4j.dlt.raw, use default value: null
