I wrote a script to parse my data per hour, price per hour and compute the time of use price and total daily price (which can sometimes yield a negative price with a positive consumption if my solar panels do a good job during sunny hours). http://marc.merlins.org/perso/solar/2009-11.html#Brand-One-Powermeter_-Solar-and-Power-Monitoring-with-Cacti-and-Real-Time-PG_E-Time-of-Use-price-calculation Does that help? To see what energy I used/made during a timerange, I just zoom on it, look at the average number and multiple by the time interval I'm looking at.
