I have a couple of flows that charge my home battery when prices are low and makes it discharge when they are high.
this works mostly fine but sometimes the difference between the high and loW price is to small to effectively earn money (when they are closer then 10 percent itmis effectively more expensive to use the home battery then just use power.
does anyone have an idea for a for a formule that calculates the difference between high and low in the next 12 hours and then makes that a percentage of the low price ? If I can do that I cancmake this work only when it is worthwhile..
Thanks !
