How to configure Homeassistant Energy Dashboard

[thomasramm]

How do I configure the Homeassistant energy dashboard correctly?
In the energy dashboard I need Wh or kWh values ​​for charging and discharging. So i have only set the PV-Module. The Energy Dashboard don't show my battery storage.

relevant noah-mqtt sensors

• BAT0 SoC= 61 %
• Charging Power = 110 W
• Discharge Power = 0 W
• Generation Today = 4,90 kWh
• Generation Total = 1 826,80 kWh
• Output Power = 536 W
• SoC = 61 %
• Solar Power = 651 W

PV-Module settings

• Energy -> Generation Total
• Performance -> Solar Power

Home storage battery system settings

Energy into Battery = ??
Energy from Battery = ??
Type of performance measurement

• 2 Sensors
  Discharge = Discharge Power
  Charge = Charging Power

(The options might have slightly different names; I translated them myself from German to English for this conversation).

You have to create integral sensors (helpers, Wh or kWh) for both battery charging and discharging sensors (W). Select these in the energy dashboard setup then.

Setting up the Home Assistant Energy Dashboard

Settings → Devices & Services → Helpers → Create Helper

-> Integral Sensor

For Battery Charging

Name: Noah Battery Charge Energy
Metric Prefix: k (kilo)
Time Unit: Hours
Input Sensor: 0PVP...Charging Power
Integration Method: Keystone Rule
Accuracy: 2

OK.

For Battery Discharge

Create another integral sensor:

Name: Noah Battery Discharge Energy
Metric Prefix: k (kilo)
Time Unit: Hours
Input Sensor: 0PVP...Charging Power
Integration Method: Keystone Rule
Accuracy: 2

Save.

The following two sensors now exist:

sensor.xxxxxxxxxx_noah_battery_charge_energy
sensor.xxxxxxxxx_noah_battery_discharge_energy

Configure Energy Dashboard

Home Assistant -> Energy -> Settings -> Electricity

Grid

Energy drawn from the grid -> Electricity meter consumption
Energy fed into the grid -> Electricity meter generation

PV Module

Energy generated by PV -> Total generate energy (Growatt xxxxxxxxxx)
Power generated by PV -> PV total power (Growatt xxxxxxxxxx)
Forecast of PV generation -> no forecast

Home Storage

Energy charged into the battery -> Noah Battery Charge Energy (the new helper sensor)
Energy discharged from the battery -> Noah Battery Discharge Energy (the new helper sensor)
