documention: thresholds

[nschloe]

The main documentation gives

color_thresholds:
  - value: 0
    color: "#ff0000"
  - value: 1.333333
    color: "#ffff00"
  - value: 2.666667
    color: "#00ff00"
  - value: 4
    color: "#0000ff"

as an example for color thresholding. What exactly does this mean?

• Between 0 and 1.3333 we have #ff0000?
• What happens below 0?
• What happens above 4?

Hi, this should indeed be cleared up a little!

Essentially, the color_treshold value works like a minimum: if the graph value is higher than a threshold, its color will apply (highest gets precedence and the first color is used as the lowest color, regardless of its value)

Between 0 and 1.3333 we have #ff0000?

Correct!

What happens below 0?

Currently, the first threshold color is used; although we might want to expose the default color if no threshold was reached in the future (to improve multi-graph & allow for "red alert only" thresholds)

What happens above 4?

#0000ff is applied.

i.e.:

color_thresholds:
  - value: 0 # currently ignored
    color: "#ff0000"
  - value: 1.333333 # anything above 1.33333 
    color: "#ffff00"
  - value: 2.666667
    color: "#00ff00"
  - value: 4
    color: "#0000ff"

If the the first "threshold" is ignored, then perhaps it shouldn't be there at all. That'd make it clearer that the thresholds are thresholds from below.

/Hi, it looks like it’s broken or something for past few months? Or user is broken? :D

Env: HA on HAOS on RPi4

My config (skipping value 0 does nothing)

Code:

- type: custom:mini-graph-card
   name: VOC last hour
   entities:
    - entity: sensor.airquality_drukarka_voc_index
      color_thresholds:
      - value: 0
        color: blue
      - value: 100
        color: blue #'#44739e'
      - value: 200

I don't know how I managed to write it per entity not global as you said and not found it for several months :D

Thank you so much, naturally works like a charm!
