I love those things as well! We've gone a bit overboard and have "smarty" boat the traditional sailors loathe. Solar and battery monitors are wired into a Raspberry Pi for logging and graphing. I'm currently using Signal-K [0] as an instruments data server. You may be also interested in my friends project called Boat Remote [1].
