Make it compatible with WAQI.

[Ndrinta]

Given the recent issues with the AirVisual API (#42776), I'd be nice to have a backup when stuff like this happen.
WAQI looks like the only alternative for home assistant right now.

Is this feasible?

[dnguyen800]

thanks for letting me know about WAQI. I'll see what sensors are available from this integration.

[Ndrinta]

Super-quick fix if you don't want to wait.
These sensors make WAQI compatible with AirVisual Card.

This is a bodge; there are surely shortcuts and errors but for the moment it works on my config, so I am happy with this. I did my best; I am sure that my code will be gross to watch for some of the experienced chaps in here and I am open to suggestions!

I left my Location and Stations of interest in, so for you to quickly try the config with a working configuration; change it accordingly to your location.
I decided to select those 2 stations because (in my specific case) the integration populates a 3rd sensor which is not of interest (somewhere in US I think), and I thought it was a waste of resources.
I chose to make the average of the 2 sensors (for a try) but to take in consideration only the closest station for the main pollutant.

In the declaration of sensor.waqi_air_pollution_level, the attributes latitude and longitude are commented out. This because I found out these are not strictly necessary for the functionality of AirVisual Card.

[dnguyen800]

Thanks. I started implementing it but ran into some issues. I'm pretty slow so it's good you wrote a template sensor instead. Thanks for figuring out the values for main pollutant, I will add that to the code.

[Ndrinta]

I'll leave this with you. Shout if you need any help, closing this now. Cheers

[dnguyen800]

Hey @Ndrinta , I'm almost done adding WAQI support, but wanted your help on calculating this value (see red circle)

Do you know how this value is calculated? Is it possible to calculate with the data from the WAQI sensors?

[dnguyen800]

I've added in WAQI support, but I'm not going to publish a new release due to insufficient testing. It technically works, and if Airvisual has problems again, I'll probably pick this up again.

You can put the .js file in your /www/community/air-visual-card directory
https://github.com/dnguyen800/air-visual-card/blob/master/dist/air-visual-card.js

[Ndrinta]

Amazing, thanks!
I'll give it a go early next week and let you know if anything odd.

Do you know how this value is calculated? Is it possible to calculate with the data from the WAQI sensors?

As far as I know, the AQI is "calculated" in this way:
Raw concentration (pollutant) = Reference value (pollutant) * AQI }(pollutant) / 50
The main pollutant raw value isn't provided by the AirVisual integration but it's available with the WAQI integration instead. And not only the main one, but all (super cool). (Note: The value for 'Sulfur' is missing from WAQI)

Also, if I can say, the way in which IQAir derives the Air Quality Index (AQI) is a bit of a mystery:

The index formula usually considers up to 6 main pollutants (PM2.5, PM10, carbon monoxide, sulfur dioxide, nitrogen dioxide and ground level ozone), and calculates the respective health risk (or AQI number) for each one at any given time. The overall AQI number at a given moment is dictated by the "riskiest" pollutant, with the highest AQI number.

While WAQI is pretty simple and open (US EPA standard).
Sweet article you might be interdireste in (https://aqicn.org/faq/2015-07-16/air-quality-scale-in-quebec-and-montreal/faq/2015-03-20/a-comparison-of-worldwide-air-quality-scales-part-1/faq/2015-03-20/a-comparison-of-worldwide-air-quality-scales-part-1/), check the bottom of the page (Note: This article is part of a series on Worlwide Air Quality scales.), more in there. Furthermore, IQAir use data not only from certified stations but also from their (indoor) AirVisual Pro sensors they sell all around the world. I'm not sure how that impacts the data but I would't trust data coming from end users (never ever, ahah).

Hi all,

I've setup a air visual card using WAQI from a year or so.

I worked great but starting from few days values are always shown in english even if my template sensor use my native language:

@walkercz Do you see any errors in the developer console in your browser (F12) when the card is rendered?

Do not get me wrong .. the output of the custom sensors is accurate, but the output is displayed only partially in the card itself

maybe the card expect different input?

i see no error in chrome dev console regarding the card

[Swampen]

Could you try to set your template to match these sensors sensors.en.json?
After changing to localized values, the sensors must match exactly one of these to be able to translate it.

Need help on AirVisual since I try to follow everyone's guide here.

However, it seems to not be able to show its value_template

Any help?

I having the same problem here.

Hi guys. I've made a little tweak to show main pollutant value when using WAQI sensor (it still doesn't work for AirVisual tho). Can't tell if I did it 100% right (this is my first time tinkering with Lovelace cards tbh) but you all are very welcome to take a look at the code.

[fcastilloec]

I'm using only WAQI and I have the same problem. Only AQI is shown and nothing else, no text, no pollutant.

[jurgenweber]

@ngseer even using your repo; I still get:

Is this still working for people?

[c0bra99]

AirVisual suddenly stopped working for my city for some reason (returns city_not_found) so I switched to the WAQI integration. I was pleasantly surprised that this air-visual-card worked just fine with no extra sensors or modifications required, I just put the same waqi sensor for all 3 air quality entities.
