I don't know if it has been posted yet, but there is a Beta version of Plugwise available.
Plugwise notified me after I put a message in the Dutch Plugwise facebook page about statistisch of solar panels that are totally wrong. I get very varying results when switching between day, month or year stats.

You can read my story about Plugwise in Dutch. In my opinion Plugwise is going the wrong way by crippling their software bit by bit....
Please, let me (and the other visitors especially Plugwise) know what you think of their Business model. But please keep it positive. Maybe there are some good ideas they could work out.
