I like that you are working hard to be compatible with so many devices. I would like to suggest a few for consideration that I use (or plan to use)
-Fitbit (http://dev.fitbit.com/) could use this much like the ifttt for jawbone up, turn things on when I wake up
-Smart power strip (I know they have a smart things version but I currently don't use smart things, so I am planning on getting the standard version)
-Ivee. It was mentioned earlier in this thread. And at the beginning of the campaign it seemed like WW and Ivee would be working together but haven't heard anything about it in a long time.
