A Home Assistant rain radar card using the new tiled images from the Australian BOM

Hey dude! Help me out for a couple of 🍻 or a ☕!

The new Austalian BOM radar products (mobile app and https://weather.bom.gov.au/) now use map tiles to distribute the radar images. This allows for one continous map that can be zoomed and panned seamlessly. This card allows this to be displayed within Home Assistant. The one drawback of the new system is that currently the BOM only publishes new tiles every 10 minutes (compared to 6 minutes with the old radar products) and there is a bigger lag in them being published. This results in the most recent radar image being between 10 to 20 minutes old at any point in time. The upside is that the radar tiles are available for a much longer time frame. This means you can create radar loops of up to at least 24 hours. The alternative tiles provided by RainViewer update every 5 minutes and are much more timely.

All of the options below can be selected using the GUI config editor, there is no need to edit the yaml config directly.

There are currently two sources of radar tiles available. The standard tiles provided by the Australian Bureau of Meteorolgy and an alternative set provided by RainViewer (with 8 different colour schemes). The BoM tiles are only updated every 10 minutes and lag by a further 10 minutes (ie. the most recent image is between 10 and 20 minutes old). The RainViewer tiles are updated every 5 minutes with a lag of just one minute (ie. the most recent image is between 1 and 6 minutes old). The valid values for this field are:

• BoM
• RainViewer-Original
• RainViewer-UniversalBlue
• RainViewer-TITAN
• RainViewer-TWC
• RainViewer-Meteored
• RainViewer-NEXRAD
• RainViewer-Rainbow
• RainViewer-DarkSky

Specifies the style of map to use. Valid values are:

• light
• dark
• voyager
• satellite

These are based off the Carto and ESRI map styles that are available.

This is the configuration used to generate the radar loop on this page.

type: 'custom:bom-radar-card'
frame_count: 10
center_latitude: -25.567607
center_longitude: 152.930597
marker_latitude: -26.175328
marker_longitude: 152.653189
show_marker: true
show_range: true
show_zoom: true
show_recenter: true
show_playback: true
zoom_level: 8

This will display a radar for the whole of Australia showing the previous 24 hours of radar images with a 100mSec delay between frames.

If you use HACS, the card is now part of the default HACS store.

If you don't use HACS (seriously you should as it makes life so much easier), you can download the required files from latest releases. Drop all of the files in www/community/bom-radar-card folder in your config directory. It should look like this:

    └── ...
    └── configuration.yaml
    └── www
        └── community
            └── bom-radar-card
                └── bom-radar-card.js
                └── home-circle-dark.svg
                └── home-circle-light.svg
                └── leaflet.css
                └── leaflet.js
                └── leaflet.toolbar.min.css
                └── leaflet.toolbar.min.js

Next add the following entry in lovelace configuration:
