Gadget Freak Case #151: Warm up to Remote Energy Monitoring

Does Apple's iPhone really have "an application for everything?" Benson Hougland thinks so. He built his own energy monitor for use in his home. A programmable automation controller, a power-monitoring I/O module, and two current transformers let him measure current and voltage to provide power-use data in real time. And Benson can tap into his system to collect power-consumption data from anywhere and view it on his Apple iPhone. The result? An interactive, real-time awareness of energy use that helped him save $200 a month on his power bill.
