New user here. Suspect I'm being thick, but I can't seem to change my timezone. Manually updating coordinates doesn't help. From description it takes it from the growatt inverter but there's no obvious way to update the coordinates that I can see (the time in inverter itself is wrong half the time but that's a known non-issue as it still does as it's told at scheduled times!)
It's probably not a massive issue, just that the time periods where it's cheap/expensive are all out by 12h! :)
Many thanks for any help!
