Super cool stuff, anyone who's dug into this know how the integration for the actual measurement works? Would it be possible to use with some shunts or hall effect sensors for DC applications with a little electrical shoehorning? I run about half my stuff off DC directly for increased efficiency and save that this would be perfect.
