Using mightyohm’s tutorial to hack the ASUS router for use with the Tweet-a-watt – you don’t need a computer to report your power usage, just a hacked up Wi-Fi router (m4v).
The Tweet-a-Watt kit is a DIY wireless power monitoring system. The project uses an ‘off the shelf’ power monitor called the Kill-a-Watt and adds wireless reporting. Each plug transmits the power usage at that outlet to a central computer receiver. The receiver can then log, graph and report the data. This pack contains nearly everything* necessary to build a single outlet monitor and receiver. To monitor additional outlets, you will need an add-on transmitter pack. One outlet can monitor up to 1500 Watts.
