I'm currently on Octopus Go (the normal one) that should start charging at 00:30pm. This is what I set in my wonderwatt schedule settings. But every night my givenergy inverter "Timed Charge" setting changes to 11:30pm start. I can turn it off, or change it to 00:30 but the very next night its back to 11:30pm.
Weiredly, most nights the battery usualy starts charging at 00:00, meaning charging for half an hour on expensive electricity. I can't understand it? Something is definately messing with my system.
