VRM Battery capacity used kWh - Li BMS as battery monitor

Is there an accurate VRM data field showing used battery capacity (kWh used)? The battery is Lithium with its own BMS as battery monitor and no external BMV. Battery summary widget only shows power output etc. Maybe the only way is to take total solar generation and subtract AC power delivery but there will be some variance...

Hi Jaques - the only way I know of (for now) is to use the dashboard, select consumption and then select a useful range (past 2 days or past 7 days both give useful info, the 7 day one counts from 00:00 to 23:59 so it might show usage split over two discharge periods)

Ah yes. That makes perfect sense! Much appreciated...

See MurrayNated’s answer for the best way, but for completeness there is another way with slightly different features as well, in the advanced tab, click the export button up the top right, and select kWh.
