The absolute energy consumed shall be ever growing
At the moment the energy_abs value is reset on power cycling the AC011K.
This value should be persisted and survive reboots of the GD chip.
Solution I'd like
Just save energy_abs onto flash.
Additional context
If this value is not persisted, and the ESP32 reboots during charging, the values are off and lead to wrong tracked charges with negative energy_charged values:
