I am not sure how all this works yet so bear with me.
I have a VeraPlus Z-wave controller. This is a standalone controller/box with its own IP etc. so it is not part of the HTPC I installed Engen on - presumably this is why I am getting an error in the log.
(btw: when I run Engen I don't get an error message.
Here is my log file:
2016-05-25 09:42:26: main:The zdriver failed to initialize: '('Multiple devices found: %s', ['COM5', 'COM6'])'. Aborting...
2016-05-25 09:42:26: main:Leaving start_from_service

Also of note when I installed OneRemote on my phone and did a search it did seem to find my controller with the message: "Linux/3.10.14, UPnP/1.0, Portable SDK for UPnP devices/1.6.6
