My Shake already updated to 0.18, no issues found.
My Boom is still on 0.16 showing Server connection: not connected. Does this disturb the auto update process?
Release notes of 0.18 are not yet online, just for info.
Cheers

I just rebooted the Boom and the device updated to 0.18 
All seems to be working.
Had to reconfigure the sensor type to yellow/20 sec.
Static IP is working
Datacast contains two IP addressee: 10.0.0.4 and 201.16.18.33. What are they for? They are not in my boom.
Boom:
Static IP had to be set two times, than it was stored.
So it looks, like all is working fine again…
Many thanks for your support and fix
Jochen
