Hi Jim/JR guys - I'm a regular MediaCenter user and have been using OpenHab for the last year or so for automation. I've played around with Engen a bit (less than an hour, but still) and like the idea of integrating some of the scheduling from MC and perhaps moving forwards with it for more regular use (I'm buying a licence regardless - you guys do good work, and I don't mind supporting even if I end up not using Engen/OneRemote/etc).
I do have one request - Phillips Hue support. I saw a comment farther down about Z-Wave vs Zigbee, etc, etc, and frankly I'm not sure that it matters that much; and there are lots of Hue bulbs floating around, which makes for a decent business case.
Phillips Hue also happens to provide a decent web api - it took me all of 15-20 minutes to do basic control of my bulbs through Fiddler (you need access to add JSON strings to the body of the message in a PUT, but GET commands can be executed from a browser - unfortunately these seem to be mostly informational). There's also a "sync" issue - ie, press the sync button, fire off a GET command, and get a registered API key for all your URLs....
I suspect that wrapping the Hue API then redelivering would not be a terrible amount of effort - I've noted some wrappers on GitHub that would make this very quick indeed, if one exists within the same language that you are using from Engen.
I'm also happy to volunteer a bit of time to help out on the technical side (coding/architecture/research/advice) if you are interested.
Cheers,
Brendon
