since version 0.80.0b1 minimum brightness slider has been set to 1, because it was considered a bug the slider being able to go all the way down to 0.

this is an unfortunate series of events, breaking a fundamental option in the HA interface, which was so easily adjusted, if needed, by the custom-ui.

please see if there is anything possible, to re-enable this, overriding the minimum brightness of 1?
