Dual gauge card

Two gauges in one, built mostly with CSS.

Heavily inspired by ciotlosm's gauge-card, but completly written from scratch.

Config

Name	Type	Default	Description
title	string		Common title
min	int	0	minimum value
max	int	100	maximum value
colors	object		color config (optional)
shadeInner	bool	true	shade (darken) colors of the inner gauge by 25%
cardwidth	int	300	width of the card in pixels (see below)
outer	object		config for the outer gauge
inner	object		config for the inner gauge

gauge config

Both gauges have the same attributes:

Name	Type	Description
entity	string	entity id
attribute	string	use this attribute of the entity instead of its state (optional)
label	string	label for this gauges value (optional)
unit	object	unit to add to the value (optional)
min	int	minimum value
max	int	maximum value
colors	object	color config (optional)

cardwidth

You may use the config value cardwidth to set the overall width of the card as an absolute value in pixels. All elements of the gauge are sized relative to this so that the gauge scales to this, but the card is not responsive for now, i.e. it doesn't resize automatically.

color config

Colors can be configured as list of pairs of each a color and a minimum value.

If a gauges value is greater than or equal to one of those minimum values, the according color is used for that gauge. If no color is found, the last color in the list is used as a fallback. To use a single color regardless of the value just use a single list entry with any value to always trigger the fallback.

By default, colors for the inner gauge are shaded by 25% (see option shadeInner).

The list is automatically sorted so you don't need to do that in your config - but I recommend it anyways.

common config vs. individual config

Colors, as well as the min and max values, may be configured once for both gauges or individually for each gauge. Individual values override common values.

Example

The example on the screenshot is configured like this:

- type: custom:dual-gauge-card
  title: Living room
  min: -20
  max: 40
  outer:
    entity: climate.living_room
    attribute: current_temperature
    label: "Current"
    unit: "°C"
  inner:
    entity: climate.living_room
    label: "Target"
    attribute: temperature
    unit: "°C"
  colors:
    - color: "var(--label-badge-red)"
      value: 27.5
    - color: "var(--label-badge-green)"
      value: 25
    - color: "var(--label-badge-yellow)"
      value: 18
    - color: "var(--label-badge-blue)"
      value: 0
    - color: "var(--paper-blue-400)"
      value: -40

In this example, the outer gauge has individual min and max values and uses default colors, whereas the inner gauge has individual colors and uses the common min and max values.

- type: custom:dual-gauge-card
  title: Living room
  min: -20
  max: 40
  outer:
    entity: climate.living_room
    attribute: current_temperature
    label: "Current"
    unit: "°C"
    min: -30
    max: 50
  inner:
    entity: climate.living_room
    label: "Target"
    attribute: temperature
    unit: "°C"
    colors:
      - color: "var(--label-badge-green)"
        value: 25
      - color: "var(--label-badge-yellow)"
        value: 18
      - color: "var(--label-badge-blue)"
        value: 0
