admin Yes, it does make sense. As I'm quite likely to have done SOMETHING to my slots between 19:30 and 23:00 I have split the window in two, to ensure 23:00-08:30 gets populated every day, and I'll see what happens in the pre 23:00 window - it might turn out I don't need it at all, as it is all so fiddly in there with the falling trend through the evening, while not always a consecutive fall in prices, that I'll end up doing it manually anyway. At least the programming is easier than with the Growatt interface!
