Cool UV Index gauge for my swimming pool area

I have made a cool gauge card to visualize the UV index and its level before going out to my Alfresco area. The UV in Australia can go extreme and you will need to be protected :sunglasses:

for this you need to use Open UV platform:

for automation of OpenUV I am using the suggested 30 minutes updates which gives you enough points within your free 50 API requests.

for the gauge I am using combination of cards:

  - type: custom:card-modder #UV Gauge
    style:
      border-radius: 25px
    card:
      type: picture-elements
      image: /local/pics/UV_gauge_wa.png
      elements:
      - type: custom:canvas-gauge-card
        entity: sensor.current_uv_index
        style:
          top: 50%
          left: 50%
        gauge:
          type: "radial-gauge"
          title: UV Index
          width: 200
          height: 200
          minValue: 0
          maxValue: 13
          startAngle: 40
          ticksAngle: 280
          valueBox: true
          majorTicks: ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13"]
          minorTicks: 5
          strokeTicks: true
          highlights: [{"from": 2.5, "to": 5.5,"color": "rgba(247, 228, 1, .75)"},{"from": 0, "to": 2.5,"color": "rgba(40, 149, 0, .75)"},{"from": 5.5, "to": 7.5,"color": "rgba(248, 123, 1, .75)"},{"from": 7.5, "to": 10.5,"color": "rgba(216, 23, 0, .75)"},{"from": 10.5, "to": 13,"color": "rgba(75, 46, 154, .75)"}]
          borders: no
          needleType: "arrow"
          needleWidth: 4
          needleCircleSize: 7
          needleCircleOuter: true
          needleCircleInner: false
          animationDuration: 1500
          animationRule: "linear"
          valueBoxBorderRadius: 10
          colorValueBoxRect: "#222"
          colorValueBoxRectEnd: "#333"
          valueDec: 2
          valueInt: 2  

I made the background myself to fit the gauge and my screen nicely:

I hope you enjoy. Let me know if any feedback or suggestion to improve. I haven’t figured it out if I can get the UV index from any other source like BOM.

The end result:

Cheers
Ali

Thanks for this. I will give it a try. UV sensor can also.be.obtained from DarkSky component.

yeah, could’t find it reliable for australia

Hi Ali,

Nice work! I’m trying your card out as well. Yet, I see that lovelace-card-mod has replaced lovelace-card-modder. Have you updated your code accordingly? Wondering how I can get it working with this newer card-mod module. Any suggestions?

Thanks, Roland.

Very nice work thank you for this

I have one problem, the config is the same as yours.

how can i remove the white part from the background?

thi is my code:

      - type: custom:card-modder
        style: {background-repeat: no-repeat, background-color: 'rgba(50,50,50,0.3)', background-size: 100% 68px, border-radius: "12px", border: "solid 1px rgba(100,100,100,0.3)", color: white,}

                        animationRule: "linear"`Preformatted text`

I struggled with the same issue. Was able to resolve it with 2 simple lines:

background-color: transparent
box-shadow: none

Place these 2 after the 50% markers and before the “gauge:” section

I was happy after this change.

Your background was a great starter for my other gauges:
https://community.home-assistant.io/t/allergen-and-asthma-dashboard/118793/15

I have several different displays I have to accommodate so I just have to find live with good enough. It would be great if the canvas-gauge could use percentage instead of pixels.

Amazing work! :slight_smile:

This all started from me plagiarizing your UV gauge:
https://github.com/GlennGoddard/CanvasGaugeBackgrounds

I have not fully put this in all my cards but adding

transform: scale(1,1) translate(-50%,-50%)

under the style section for the gauge allows you to successfully resize the canvas gauge without having to change the pixel size for different size displays.

I tried to do complement colors for the text but it does not always work, so for the most part I stayed with Black and White but colors are easily changeable for text. I put the text inside the yaml and removed it from the background image; this will allow non English users to change the language to whatever they want.

I see the appeal of the SunSmart logo, but did not use it on mine (yet anyway). I might add the logo to my repo though to allow others to add the picture if they want to; it would be done the exact same way I do the logos in the center of the gauge. User just needs to change position to where they want it. Order in the picture elements yaml determines what goes on top of what; lower down on the list is higher on top.

I would like to figure out how to make multiline state-labels that are not a disaster. I attempted a max word limit css new lines; nothing worked well if at all.

Anyway, your work has made my dashboard look so much better. I have had many people comment on how good they look; so I might as well let you know you stated all this.
