@marceltrapman Frankenstein's Monster? :D

So, the UI is not detecting anything, although testing mysgw shows it receiving data. Is this a misconfiguration on my part?

Edit: Nevermind. I think what you said just sank in. Thanks for your help!

@TimO I'll be honest with you: I'm not sure I configured everything properly. I don't have things or items files, because I set things up through the PaperUI. Do I need to set everything up through config files?

I've attached the complete log file. I'm running stable.

Thanks for your help!

Edit: Nevermind. I don't have permission to upload a file. So, here's a pastebin: http://pastebin.com/jLeTXbvX (the timestamps are wrong, you can ignore the date).

Edit2: One thing that I was having trouble with was determining the Node and Child IDs. I finally settled on what I think they are (105 and 255, respectively), but I may be wrong. Any advice with regard to figuring that out would also be greatly appreciated!

I was able to successfully install the binding, but when I added a temperature sensor as a test, it keeps failing. This is the error message I'm getting:
