@fishermans I'm glad to hear that! I'll upgrade to RC1 soon, thanks for reporting back!

@TimO now I tried the new combination of a recent OH2 snapshot as of 2016-12-21 with the recent mysensors binding. I had to restart the gateway and every single node but then everything works well. The nodes were found in the inbox and could be acknowledged as new things. Values are transmitted regularly and my relay node follows the switch items as desired. So no glitch at the moment. Well done @TimO.
