So, maybe the problem is, that bypass is still true ore? But there is no sun atm (heavy thunderstorm, totally dark here) Or is the problem the sunset/rise setting and he did not try to change the bypass to false again?

If yes, would it be a better idea to not check the time, instead of checking solar input? Like a new setting enable_batterie_at = 20w e.g. and if the solar is below of this value, it's like the sun is gone ? :)

i disabled the bypass mode manually. now it works.

okay, worked like a half :D because of the minimum-charge level and still really dark weather, sc like to charge the batterie instead of feeding the house :(

reinhard-brandstaedter commented 4 months ago

So, maybe the problem is, that bypass is still true ore? But there is no sun atm (heavy thunderstorm, totally dark here) Or is the problem the sunset/rise setting and he did not try to change the bypass to false again?

That might lead to the same issue as the firmware has: a lot of (unnecessary) switching on the relay, e.g. cloud's on/off. I considered the option on low light conditions but then discarded it again for exactly that reason. A typical summer thunderstorm hits and then leaves rather quick again, with sunshine afterwards. So leaving the bypass on is a reasonable "drawback".

busaku commented 4 months ago

Hmm, yes you are right. Just thinking: What do you thinking about an setting like if darknessTime > x minutes and timeToSunset > y and dailyByPassSwitch ount< z: disableBypass()

Maybe all settings configurable with min/max values?

reinhard-brandstaedter commented 4 months ago

Nah that doesn't provide much value, just makes things more complicated. If you want feed-in from the hub throughout the day, you can adjust the morning/evening offset time-ranges, that will give you the same result.
