I am working on a service which will take current energy production data from my PV solar monitoring system and store it in the weewx database, to be reported to a modified version of the (pre-4.2) Seasons skin. The data I want to store is already being written at 5 min intervals to a transient file on the Raspberry Pi on which I am running weewx, so so far, so easy. I would also like to *display*, in 'Current Conditions', but not store, current totals for various periods (e.g. Today, this month, this utility billing period, this year). I assume that the Report generator could compute these from the archived energy generation values, but accurate values for all these totals are already available in the same file that contains the current production data, and it seems stupid, as well as potentially error-prone, to recalculate them. Is it possible just to make such values available to the report generator - e.g. by inserting appropriate tuples in Loop or Archive records within the Service?
