I use the Energy Dashboard but from Tiome to Time i get huge negative readings.
I have engery meters that dont reset, they increase kwh like a energy meter should (see in the grafana dashboard)
In home assistant energy dashboard there is a huge negativ…
it makes no sense for me, the next thing that wonders me is that the meeter wasnt able to read data from the sensor a few days, you can see the jump at the end from the graph, at all the time the sensor was present to home assistant. (esphome with a sd230? meter)
the jump there is about 120 kwh, so ha should know that and dont make a jump that big 
could it be that HA has a problem with “NULL” or “N/A” readings? and if yes we should consider filter them out in the Energy integration i think
