Hi Patrickse,
it seems, that updating the plugin as well as updating openhab didnt solve the issue. My logs are full of the following entries:
2018-12-27 07:40:03.452 [ERROR] [ng.volumio2.internal.Volumio2Service] - Timedout while conntecting to Volumio on volumio.local.

The status change from offline to online happen whenever i update my thing to the local ip adress, meaning volumio.local does not work. but i can reach volumio via webbrowser by using this adress.
Any ideas?
