After outgrowing the capability of his Homeseer home automation system this guy decided to build his own. The system consists of a wide variety of hardware, everything from off the shelf X10 to custom build modules. For example to monitor his electricity consumption he is counting the number of times his meter flashes in a minute. What does it monitor? The easier question is what doesn’t it monitor… Currently it
