Maybe try this link.

Oh wow. What’s the deal? 
No deal. Just an unofficial api that can easily be found if you know how to 
Legend. I actually had a dig around for it too but couldn’t figure it out.
thanks, this is super helpful!
I’m chipping away at it and making some progress. Don’t really know what I’m doing though.
I’ve been trying to hack something together this morning to use the asthma forecast.
The HTML nested within the JSON makes it hard to work with.
my solution at the moment is this:
I’m using a shell command to extract just the asthma forecast HTML from the API (this is div 5)
asthma_refresh: 'curl "https://api.pollenforecast.com.au/app/json/app_data.php?app=1&version=2" | jq .div5 >/config/www/asthma.html'
I’m running this as a service every 30 mins.
I’m then running multiscrape over the output:
- resource: http://[IP address]/local/asthma.html
scan_interval: 3600 #3600 sec = hr
name: Asthma forecast
sensor:
- unique_id: asthma_forecast_scrape
name: Asthma forecast
select: '#\\\"ta-forecast-table\\\" > tbody > tr:nth-child(1) > td.\\\"center\\\" > p'
attributes:
- name: Website Last Updated
select: 'body > div > div > div:nth-child(8) > p'
This is not a neat way to do it, but it does give me a sensor in homeassistant.
if it works, it works! you’ve made great progress

Hey guys, Multiscrape is now also supporting json: Scrape sensor improved - scraping multiple values - #188 by danieldotnl
It might help you to merge your rest and template sensors into one.

Appreciate the heads up @danieldotnl .
The thing with the api we are using is it actually has html nested within the JSON.
So we kind of need to be able to first do some JSON type selects and then do some HTML based selects on the results.
Any thoughts on if we can tackle this query chain with just Multi-scrape and the new features?
It would be great if so as our current solutions are clunky.
Thank you.
Thank you so much for this!!
For anyone playing in 2022 this still works

No prob. I’ll be revisiting it closer to spring, as I definitely would like it working.
They seem to change what data they offer almost annually.
I use it to plan my week, alert me about the day, close my windows, turn on my air purifier etc. Basically manage my exposure.
I’ve told the boss I’ll be trying to work from home on Extreme days etc.
HI
I have manged to get both the API and HtML working.
But for some reason when I try and add it to Lovelave, the code fails
ButtonCardJSTemplateError: TypeError: Cannot read properties of undefined (reading '0') in 'return (states['sensor.melbourne_pollen_forecast_api'].attributes.melbourne_6day_pollen_forecast.d...'
I pretty much copied the lovelace card, so not sure what exactly, i am doing wrong
Thanks as always
Thanks for getting back to me
Here is a screenshot of the api sensor
It seems to have a slightly different formatting, which I think might be why the lovelace doesn’t like it.
Here is the code I used for the rest and template sensor
rest:

#Change myDistrict value above to one of:

# Mallee

So not sure if I have misconfigured something.
Thanks you, that appears to have worked. Thanks…

Great work @Mahko_Mahko. I set it up a couple of days ago and it was working fine until today when I ran into the same issue with rendering cards as @obrien.craig.

Mine appears to have broken too. Stay tuned. Seems to just be the card.
Not sure what’s up with the Thunderstorm Asthma forecast for this season.
Also at time of publishing one day of forecast seemed to be missing (from the API).
Will monitor that.

Mine’s broken again lol. Stay tuned…
And so hilariously this has now changed back to lower case and so I’ll revert back to previous code. If it happens again I might do something smarter…
