Various stats captures from the myenergi eddi PV diverter. The YYYYMM[DD].log files capture eddi stats every few minutes. * Each line is a record. The YYYYMM.daily.csv files capture a by-day summary of diversion and boost. end the eddi's views on overall grid import and export. * Each line is a record. * Lines starting with # can be ignored as comments. The YYYYMM[DD].freqResp.log files capture grid-support frequency response. * Each line is a record. * Every minute if the eddi state is boost, divert or stopped then grid frequency is checked. * If grid frequency is too low (eg <49.9Hz) then the eddi is stopped, adding supporting power to the grid, and a log entry is made. * if grid frequency is OK then the eddi is resumed if stopped. * Each continuous sequence of records showing state 6 (stopped) whould be preceded by one in state 3 or 4. * Analysis of this initial record in particular indicates how much power was repurposed for grid support, eg anything boosted, or anything above the export threshold.
