My first observations...

A glance at my USB connect graphs took me to the conclusion that on weekend days we use more electricity than on week days. yesterday out highest peak was around 2 pm where the graph rose to 1.884 kwh. . Our lowest was around 5 am where we used 0.43 kwh. in total we used 19.86 kwh, but on the week days our highest peak was 7pm, 2.086, whereas our lowest was at 6am - 0.436.
