So, just a quick note. I just updated the code for the power summary (which is on the left), and fixed the “current meter reading”. There were a couple issues, one of which was a bad sql query (not sure why the previous one didn’t work, but oh well), and for some reason, 2 days of data were missing (which you’d see if you clicked the “history”, and saw two “0” graph points.
Anyway, after fixing those problems, it turns out the “current meter reading” is dead on. I’m not sure how… and maybe it’s just a coincidence, but the meter reads exactly what the webpage says. Not too shabby. That means the drift for about 33 days is less than 1KWH, or less than about 300W per day, which given a 30KWH day, that’s less than 1% inaccuracy.
So, that’s it. Just thought I’d share. =) More actual interesting info later today, or tomorrow.
