Hello,
I had the same look of chart when I was providing an entity with wrong entity type, unit of measurement or device class.
I don’t recall for sure but you need:
Device class energy
UoM: kWh or Wh
If the entity of the battery is like charge 15kW it would not work.
This is just a guess.
Setting the Battery Power sensor to “Inverted” has fixed it when the batteries are discharging. I’ll have to wait and see if the Sankey is then wrong when the batteries are charging from grid…as the Sankey has been correct during charging previously.
well, not sure that is correct.
In energy dashboard setup there is power in battery and power out of battery and these are energy (Wh), the sensor that can be set to inverted is the power so (W), I’m not sure it will work.
do you have the other two sensors correctly setup?
