Slider option - minimum value (Lights)

[Nornode]

Is your feature request related to a problem? Please describe. I'm always frustrated when sliding a dimmer to the lowest value, it turns my lights off, not to 1% light.

Using the toggle to turn it off completely

Describe the solution you'd like on slider: definition implements a min: (And a max:) configuration.

e.g.:

    slider:
      direction: left-right
      background: gradient
      use_state_color: true
      use_percentage_bg_opacity: false
      force_square: false
      min: 1
