Currently my setup is running in ESS mode. On some days there is not enough solar generation to bring the batteries back to 100%. I’m playing with Node RED and would like to achieve something like:
If expected solar less than X kW
Determine lowest energy price for Y hours.
Set Charging Schedule to charged from Grid ad lowest energy price time and Y duration.
End
Determining the expected solar is possible through the VRM API and “Solar Yield Forecast”.
How can I determine the lowest energy price? I’m using Zonneplan with dynamic contract.
