Thank you for your help. I had restarted my nodes with reset button.
I tested the following today:
-restart my raspberry gateway
-restart mysgw.service. Don't know why, it starts automatically and then gets killed:
Aug 07 20:48:57 gateway systemd[1]: Started MySensors Gateway daemon.
Aug 07 20:49:40 gateway systemd[1]: mysgw.service: Main process exited, code=kil
Aug 07 20:49:40 gateway systemd[1]: mysgw.service: Failed with result 'signal'.
So I have to restart it manually with sudo systemctl start mysgw.service .
-Once the service was active , I turned on my sensor at 20:57. mysgw log says:

Waited two minutes as proposed, then I went back to Webthings gateway and triggered a thing detection. It does not seem to work better:

Finally says no new things found.
So I'm afraid I did not make any progress since yesterday
