Difference between production and consumption

[Juju-35]

Is it possible to scrape the difference between the production and the consumption on ECU-C model ?
The information is disponible by querying "http://X.X.X.X/index.php/meter/old_meter_energy_graph".
The result is a json like that :
{ "energy1": [ {"date":"20250903","energy":10.95}, {"date":"20250904","energy":10.21}, {"date":"20250905","energy":12.73}, {"date":"20250906","energy":14.23}, {"date":"20250907","energy":9.74}, {"date":"20250908","energy":10.26}, {"date":"20250909","energy":7.03} ], "energy2": [ {"date":"20250903","energy":-4.87}, {"date":"20250904","energy":-3.38}, {"date":"20250905","energy":-5.04}, {"date":"20250906","energy":-7.98}, {"date":"20250907","energy":-2.28}, {"date":"20250908","energy":-4.44}, {"date":"20250909","energy":-2.13} ], "total_energy":"0", "subtitle":""}

I saw that the energy2 field is the difference between th eproduction and the consumption: a negative value means that the production is returned to the grid and when there is a positive value, that means the electricity is consumed from grid.
With this value, it is possible de have the electricity consumed by the house.

Currently these entities are available for the ECU-C and are derived from the url mentioned above:
sensor.ecu_{ECU-ID}production_ct_a..c
sensor.ecu{ECU-ID}grid_ct_a..c
sensor.ecu{ECU-ID}_consumed_a..c

Thank you. After a research on how to obtain values in kWh, it's OK.
