You know you’re wasting electricity around your house. And as a geek, you’ve always dreamed of being able to run your home from a portable device – maybe something slick and hand-held? Well, this fellow got the DIY spirit and made it all happen:
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.
