Have you given it time to work out what is happening? I think it takes a few days.You know, that's what I thought! BUT instead it wants to start the day with 54% battery charge and for some dumb reason it starts discharging well in the off-peak period... Crazy algorithm man. Next time i send screen shots...
As I said, mine works very well. The battery goes to 100% during Off-peak, maintains it at 100% through most of the Shoulder and doesn't use the grid at all during Peak, unless the battery drops to Reserve.
It also anticipates sunny days, like today, where it started using that battery before Peak started knowing there'd be a lot of solar.
