I am trying to graph multiple daily energy feeds on a single daily graph on a local raspberry pi based emoncms. The historical daily energy feeds are generated via input processing using the Power to kWh/d process. The Forecast solar energy feed data is generated from Solcast data using node red and loaded using the Feed API. :
My difficulties are associated with the type of graph selected. If I select a Fixed Interval 86400sec graph type, the current day’s data is shown on the previous day. If I select a Daily graph type, the current day’s data is shown on the correct day however the future forecast data loaded as above is incorrect on the graph. The CSV outputs of the subject data for the two different graph types is shown below.
As there is only one data point for each day for the forecast, I can’t imagine how the Daily graphing function can generate a different value.
Can someone point me to an explanation of the Daily graphing function or help me get the correct values displayed on my Daily graph?
