I’ve been happily moving along with my two IotaWatts but since these things give a level of customization that’s above and beyond I wanted to dial in the accuracy.
When I first installed my IotaWatts I calibrated the voltage from 10.79 down to 10.75.
My last billing period showed that I was a net consumer of 374 kWh
During the same time the IotaWatt that measures the mains calculated 385 kWh
Which right off the batt is stunning accuracy!! Amazing job @overeasy!!
I want to get even closer because why the heck not! Does this math check out for further calibration?
[Old Calibration Factor] - (1 - ([PoCo Power Usage] / [Measured Power Usage]))
New Calibration Factor: 10.724025974
Either way I’m not sweating it because it’s already quite accurate for my use case.
