One note to add. If I subtract the solar production of 28.362 from the net usage of 25.707 I get -2.655. If you round that up, you get the 2.7 kWh that my utility says I exported.
Alternately, you can subtract the 28.362 from Total Usage of 47.251 to get 18.889. And then if you subtract the 21.544 Balance from that, you once again end up with -2.655. So the data to compute what I’m exporting is there, it just can’t be easily presented in the app.
