I’m hoping someone might be able to clarify the use of the Cumulative Flag when it’s set to 1 (c1=1). Currently I am making API calls with v1 (Energy Generation) and v2 (Power Generation) also voltage and temp. It appears as though that the PVOutput site is always 100Wh behind what the API is sending for v1, eg at 08:55 this morning v1=700 however the site is only showing 600Wh. This is pretty consistent over the entire day. Does the flag do anything else other than represent that v1 is reset to 0 at the start of the day? Perhaps some sort of calculation?
Happy to provide more data if needed.
