under Developer/Statistics the graph is shown correctly
but the statistics card shows a different picture: Below max and sum values. Bevor feb 3 no curve is shown.
after feb 3 the curve stays on the same value, resulting in a straight line.
Do you happen to have a GoodWe inverter? I’m facing the same issue. I guess it has something to do with the fact that the inverter becomes unavailable when it’s not producing energy anymore. The top image shows historical information, the other images show statistical information. I’m no sure why, but the history-graph and statistics-graph behave differently when there’s no sensor data coming in.
