Electricity, gas and water are typically some of the largest regular expenses in any household. Having the ability to monitor trends in utilities usage means that you can easily notice discrepancies and pick up gas or water leaks promptly, saving you unnecessarily high bills! Plotting the daily electricity usage allows you to find out which devices or activities are inefficient and optimise your home accordingly, saving your even more money! This project from Chris Nafis uses an ethernet connected Arduino to send the information it collects from utility meter data packet broadcasts, onto the internet.
