Hi, everything was fine last March. As soon as April started, in the energy panel in the current year view all the data from March was moved to April. March is empty. In other reports like the last 12 months, quarterly or monthly view everything is ok.
This has happened to me repeatedly. It has happened to me on two out of three HA installations.
Did you possibly switch to daylight saving overnight? Maybe your sensor platform doesn’t handle that well. Are the two that are wrong the same type of sensor?
