Power Meter Settings - JSON - Results = difference between two values

[FilipeAmadeuO]

Hello
I have configured Power Meter Settings - JSON correctly but i am only able to get one result.
Is there any chance for the results to be the difference between two variables ?

Explaining better:
I get export and import energy value. The goal is to get the difference export minus import.

Found solution by configurating Phase 2 + Change Sign.
