+## Energy Dashboard
+
+This card supports partial Energy dashboard integration. You still need to specify the entities and connections for now. See `energy_date_selection` option.
+
+Currently this chart just shows historical data based on a energy-date-selection card. It doesn’t know/care if your entities are in the default energy dashboard.
+
+### Total [daily] energy
+
+There isn’t a general Consumed Energy sensor in the HA Energy dashboard AFAIK. HA calculates it based on all the in/out kWh values. I can’t tell you exactly how to calculate it because it depends on what values you can monitor. Some people already have a Total Consumption sensor, others have a Current Consumption and create an integration sensor from that, etc.
