I am seeing this in my logs when I switch on/off my Qubino Flush 2 Relays:
[INFO ] [class.ZWaveMultiInstanceCommandClass] - NODE 5: Received a multi instance encapsulation with a destination endpoint = 2.
[WARN ] [class.ZWaveMultiInstanceCommandClass] - NODE 5: The originating endpoint is 1. Please notify author.
Is this [WARN ] a problem, or can it be ignored? I was wondering about “Please notify author”. The Switch functions fine, but I have a test setup and currently only 2 ZWave Things/Devices. Though I am now very convinced about OH2 and have ordered some more ZWave devices 
I am running OH2 unstable.
