Flukso is an open source (HW & SW) web-based community metering application. Flukso allows you to accurately monitor and reduce your household electricity consumption via its website and API.
This talk will focus on the embedded development of our 801.11g wireless sensor node called the Fluksometer. Fluksometer development went through several iterations. It evolved from a hacked-up Arduino - WRT54G prototype, via an Arduino Wee - Fonera in alpha to the custom sensor board - Abocom WAP2102 which we are now using in our beta trial.
This hybrid approach, connecting a custom sensor board to an off-the-shelf wifi router via UART, allowed us to develop a generic sensing platform that can be used for monitoring almost any physical unit, provided a suitable sensor can be found. We currently focus on measuring household electricity consumption and, in the near-future, photo-voltaic production. We will present our sensor node's hardware (AVR and Atheros AR1217) and software (based on AVR-libc and OpenWRT 8.09) architecture and discuss its (dis)advantages and a lessons learned.
