I am similarly frustrated by the inability to graph “total usage”.
I have sensors on the solar lines coming into my panel. I also have sensors on the main lines that run from my breaker panel to the meter. This gives me a lot of nice information. If I enter the Emporia app and hit the “graph” icon, then hit “day”, I will see how much power I drew from or pushed into the grid on that day. The numbers for each day correspond very closely to what is shown on the myPGE website. I can click on my “solar” line in the main screen, select day for the interval, and then see my total solar generation for each day.
The one metric that I also track is how much power I am consuming each day. Sometimes I see unexpected anomalies in consumption that cause me to investigate what is going on or take steps to reduce high consumption activities. However, the only way that I can easily see trends in my total power consumption is to download the data and use a spreadsheet to track it myself.
I recognize that total usage is a calculated figure and consequently may not have specific entries in the database that holds the measured sensor values. But isn’t net usage (which is graphable) also a calculated value? Can’t the same technique as is used for net usage be used for total usage?
My bottom line is that graphing total usage is highly desirable for those people who want to manage their power consumption. Isn’t that the center of the Emporia target market?
