Die Annahme, dass ich nicht meine gesamte Energie im Laufe des Tages verbrauche, ist falsch. Ich verbrauche sie komplett! Wenn mein Akku geladen ist, schalte ich so viele elektrische Geräte wie möglich ein.
Korrigier deinen PV_Battery_Charging-Sensor und dann beobachte den Verlauf die kommenden Tage - das sollte dann besser werden. Und so weit schien SFML ja nicht daneben gelegen zu haben. Den Wert kannst du ja auch unter Sensoren in SFML ablesen - wie gut es bisher war.
Well, maybe lets switch to english fo this technical detailed discussion, because it seems that some informations are missing for both sides because of the translation. And normallyif you are using a translator, mostly translation from english to your language works better then from german.
So, according to your logfiles you have also good results, which also your screenshot from Post 20 shows. AI Metrics with 0.92 is nearly perfect.
Next, please check your Sensors, specifically the one for the “Solar to battery” of your system. If this one doesn´t work ( less than 50W ), SFML thinks MPPT-throttling is always active and excluding the hours from learning!
And it doesn´t make sense to turn of the option “battery storage”, it will make it more worse, because without activated option, if you are running into a full battery the AI will learn “I have full sun and input of 200W”. Please only deactivate “zero feed in”-option.
As @nobbilie wrote, correct your PV_Battery_Charging-sensor ( please check that only Solar to battery will be shown for this sensor) and have a look during the next days if it will be getting better. If not, maybe a complete restart will make sense with clean sensors and due to this clean values.
Kaysen is correct—your forecast accuracy has been exceptionally high given the short timeframe. Also pls check your internet-conection
Furthermore, his observations regarding the option flow in relation to MPPT throttling are 100% correct. I would also be interested to see the data from the STATS module regarding this accuracy. Could you please share a screenshot?
In my experience, STATS provides significantly higher precision than the standard Home Assistant Energy Dashboard due to its superior data processing arithmetic.
