What happened?

The DESS Minimum SOC resets after a few minutes back to the ESS Minimum SOC and is never applied/used.

Screenshot after changing the value from 10% to 25%:

Screenshot_20240414-120514

After a few minutes and/or a change in the DESS config (eg battery capacity), the value changes back to 10% without notification. VRM also never shows the 25% value in the forecast.

I can't use DESS like that as my forecasted consumption at night ist always off.

When did it happen?

This is a remnant of an older implementation that should have been removed from the menu a while ago. But we forgot about it. And it adds confusion. Sorry about that. This menu option will be out in the next release.

You need to adjust the regular Minimum SOC (unless grid fails), which is also used by DESS (and one menu up). You can also check the current value on VRM under the controls.
