As you can see there is a spike to almost 7000kWh at 20:28:30.
Why its visible this plot, and not visible at first one?
From where this spike comes from?
So I have:
1.integral that counts total power usage → Pomocnik Prąd Total
2.I have Utility meter → Dzienne zużycie prądu total that resets every day and
Periodically resetting and Sensor always available is ON
For what reason that spikes occurs? on this utility meter?
