Irgendwie ist das schon toll: Du hast eine Hardware-Software-Kombination, die nur ganz knapp nicht das tut, was Du gerne hättest. Und weil Du’s kannst, änderst Du das einfach.
Worum geht’s? OpenDTU-OnBattery kennt zwei kombinirbare Modi, die Batterie zu entleeren: a) wenn einmal voller als $ObererGrenzwert, entlade bis zu $UntererGrenzwert; b) nach Sonnenuntergang entlade die Batterie von ihrem aktuellen Ladezustand bis zum unteren Schwellwert oder bis zum Sonnenaufgang. Beides toll, aaaaber, nunja. Eine relativ kleine Batterie möchte man ggf. über den Tag neu aufladen, anders, als die Software meint.
To make a long story interessting, ich habe den Code dahingehend geändert, daß morgens eine Entladung gestoppt wird, danach greifen die üblichen Werte.

Tja, »[DPL] it is now daytime, stopping any discharge because charge is prioritized« ist doch eine ganz vorzügliche Meldung 😉
All praise the power of Free Software …
