Since the last update (0.6.3, HEMS 2.0), I can define my Peak/Valley prices. However, in Auto Mode it suddenly starts charging the battery from the grid in valley period (while that is obviously more expensive because it's higher than the return tariff). I don't think this is an improvement.
I can turn off this behavior by selecting Self-Consumption Mode, but it would be better if Auto Mode would have the same behavior (as before the update).
When I select Fixed Rate instead of Peak/Valley (although not according to my contract), it's working as expected.
