Arc slider, Colour temp slider and Modern slider
Three sliders control light level and colour temperature on a group or device: the Arc slider for dimming, the Colour temp slider for tunable white, and the Modern slider, a stepped bar-graph style that can do either.
All three take a target from Use my targets under Command / Target.
Shared slider appearance
The Arc and Colour temp sliders share these settings under Slider settings > Slider Appearance (Reset to defaults restores them):
| Setting | Options |
|---|---|
| Thickness | 50% to 1000% of the default track width |
| Orientation | Horizontal, Vertical |
| Slider ends | Round, Square |
| Slider button | Round, Line |
| Track icons | Show a min icon and a max icon at each end of the track |
Larger thickness values make the track easier to grab on a touch screen.
Arc slider (dimmer)
Default size: 1 x 6 cells, vertical.
| Setting | Options |
|---|---|
| Show percentage | Show the current value on the widget |
| Slider type | Percentage (0 to 100%) or Arc (DALI arc level) |
| Min level / Max level | Limit the range the user can set, for example 10 to 100 |
Set a Min level above 0 where you never want the user to dim lights fully off from the slider.
Colour temp slider (tunable white)
Default size: 1 x 6 cells, vertical. The track shows a warm-to-cool gradient.
| Setting | Default | Notes |
|---|---|---|
| Min level (K) | 2700 | Warmest temperature |
| Max level (K) | 6500 | Coolest temperature |
| Show value | On | Shows the current Kelvin value |
Match the Kelvin range to the fixture's rated range (for example 2700 to 5000 K) so the full slider travel is usable.
Modern slider
Default size: 2 x 1 cells, ceiling-light icon. It shows a row of level boxes that fill as the level rises.
| Setting | Options |
|---|---|
| Mode | ARC (dimming) or Colour temperature (adds min and max Kelvin, default 2700 to 6500 K) |
| Orientation | Horizontal, Vertical |
| Style | Rectangle (equal boxes) or Ascending (boxes grow in height) |
| Number of levels | Number of boxes, default 8 |
| Minimum / Maximum value | Range covered by the boxes; the step per level is shown below (for example 12.5 per level for 0 to 100 over 8 levels) |
| Gradient fill | Fills the boxes with a gradient |
| Show value / Show icon | Value text and icon on the widget |
Inactive boxes use the theme's Alt Button Colour; active boxes use the On or Active state colour.
Choosing a slider
Continuous, precise dimming: Arc slider.
Tunable white with a visible gradient: Colour temp slider.
Compact, tap-to-level control with fixed steps: Modern slider.
A system variable rather than a light level: Data slider (see System variables: Data slider, Variable and Adjustable data).
