better user interface to control for number entities

I have one number control that sometimes I have to change, this number range is from 0 to 1440 (but most of the time I use numbers below 120).

When opening the entity there is a bar to change the number, when moving the finger on the bar we can't know what will be the exact number because of the large range.

Suggestions for this interface:

• When moving the bar indicate the new number
• Have an option to cancel the change, currently even if we move finger far from bar the number still changes, there is no option to cancel the change, and also is difficult to return to previous number because we dont know the selected number
• follow the digits of entity this specific sensor has no decimals (show correct on tile), but show one decimal place in the graph and changing bar
