Solar Stats - have a look here?

[TonyM1958]

Hi Al,

Not an issue, but a convenient ways of messaging you... seeing Solar Stats on FB - possibly worth you having a look at https://github.com/TonyM1958/FoxESS-Cloud#charge-needed

You can run this in Colab or any Jupyter Notebook if you want to see what it does with your inverter and battery: https://github.com/TonyM1958/FoxESS-Cloud/wiki/Using-Jupyter-Notebook

This uses the Solcast forecast and battery stats to produce a forecast and then sets the battery charging schedule like this:

I run it as a scheduled job in Saturn Cloud every night - but you could do the same thing in your app. Here are some example of the predicted versus actual:

The code is a bit intense to work all this out but I'm sure you will follow it...

BTW - it appears Solcast may produce forecasts using GMT so I find I need to adjust for BST. Don't know what you will get if you are in Germany, for example. You might think, given the location data that Solcast has, it could do a better job of producing a forecast using local time but I'm not sure that is the case, so something to check out for your app?
