HAEnergy dashboard
ThroughModbusIntegration willEM02AccessHAOn the energy dashboard, it automatically displays: today's electricity consumption, cumulative electricity consumption for the month, power curve, and estimated electricity bill. Combining photovoltaic inverter data to achieve the calculation of "spontaneous self consumption rate".
matters needing attention
⚠️ Please calculate the margin based on the actual load power. If the power of a single meter is insufficient, multiple meters can be added for independent circuit segmented control.
