canvas-gauge-card

Build

This card is basically deprecated and do not expect maintainence.

Development

I recommend use vscode devcontainers. do

npm install
npm run build

Inside container you can build, start HA using vscode tasks.

This card allows you to use the awesome gauges at https://canvas-gauges.com/ in your lovelace GUI. This is still a very early and untested alpha version. Tested only on chrome and safari browsers.

If you want to support the developer, please support the lib devs of the canvas-gauges.

Screens

Here is a some different screens from my own setup. But the possibilites to make your own look and feel are great.

Usage

Download through HACS (recommended) or ...

Download the file canvas-gauge-card.js from the latest release to your home assistant config. Add a module link to the canvas-gauge-card.js file. The link needs to be the same as where you put it. Example:

resources:
  - url: /local/custom_cards/canvas-gauge-card.js
    type: module

Configure the card properties.

Skip nameproperty if you dont want the name with the shadow area to show.

Use the javascript names of properties from the examples at https://canvas-gauges.com/documentation/examples/. Click on an example that you like, check the JS version and copy the properties to the lovelace yaml file. Just remove the ',' after copy from site.

Example 1, simple half gauge

ui-lovelace.yaml:

Notice the differences in card_height and gauge/height to get correct half size for full circle, set both to same.

- type: custom:canvas-gauge-card
  entity: sensor.processor_use
  card_height: 125
  gauge:
    type: "radial-gauge"
    title: Processor (%)
    width: 220
    height: 220
    borderShadowWidth: 0
    borderOuterWidth: 0
    borderMiddleWidth: 0
    borderInnerWidth: 0
    minValue: 0
    maxValue: 100
    startAngle: 30
    ticksAngle: 180
    valueBox: false
    majorTicks:
      ["0", "10", "20", "30", "40", "50", "60", "70", "80", "90", "100"]
    minorTicks: 2
    strokeTicks: true
    highlights: [{ "from": 80, "to": 100, "color": "rgba(200, 50, 50, .75)" }]
    borders: false

Example 2, simple half gauge with shadow text

ui-lovelace.yaml:

- type: custom:canvas-gauge-card
  entity: sensor.processor_use
  name: Processor (%)
  card_height: 145
  shadow_height: 15%
  font_size: 1em
  gauge:
    type: "radial-gauge"
    width: 220
    height: 220
    borderShadowWidth: 0
    borderOuterWidth: 0
    borderMiddleWidth: 0
    borderInnerWidth: 0
    minValue: 0
    maxValue: 100
    startAngle: 90
    ticksAngle: 180
    valueBox: false
    majorTicks:
      ["0", "10", "20", "30", "40", "50", "60", "70", "80", "90", "100"]
    minorTicks: 2
    strokeTicks: true
    highlights: [{ "from": 80, "to": 100, "color": "rgba(200, 50, 50, .75)" }]
    borders: false

Example 3, simple full gauge with shadow text

ui-lovelace.yaml:

- type: custom:canvas-gauge-card
  entity: sensor.processor_use
  name: Processor (%)
  card_height: 210
  shadow_height: 12%
  font_size: 1em
  gauge:
    type: "radial-gauge"
    width: 220
    height: 220
    borderShadowWidth: 0
    borderOuterWidth: 0
    borderMiddleWidth: 0
    borderInnerWidth: 0
    minValue: 0
    maxValue: 100
    startAngle: 40
    ticksAngle: 280
    valueBox: false
    units: "%"
    majorTicks:
      ["0", "10", "20", "30", "40", "50", "60", "70", "80", "90", "100"]
    minorTicks: 2
    strokeTicks: true
    highlights: [{ "from": 80, "to": 100, "color": "rgba(200, 50, 50, .75)" }]
    borders: false

Example 4, 4 gauges in a row in a horizontal-stack

This example shows gauges with or without text. This text are placed below the actual gauge this time.

Properties

Some of the properties that could be set. italic is not mandatory.

Property Description
entity your sensor
name shows the name in shadow remove to hide it
