How to add PurpleAir AQI to your Apple Watch
PurpleAir air quality index on your Apple Watch.
Do you like your Apple Watch? Do you like PurpleAir?
I certianly do and was bummed when I found out there was no way to add the current AirQualityIndex (AQI) to my watchface.
I made this for myself and am happy to share it with others who might be interested.
It's a prototype therefore the setup is not oversimplified but it gets the job done.
Air Quality Index (AQI) scale
|101-150||Unhealthy for Sensitive||Orange|
The beauty of PurpleAir is quantity of sensors placed around the city to provide the most accurate reading for your location.
The widget will query the sensor closest to you therefore you need to figure out which one it is.
To do this:
・head over to PurpleAir
・allow it to use your location
・turn off inside sensors from the control panel in the bottom left corner
・zoom in to your location and click on the closest sensor (a popup window will open)
・move your mouse over Get this Widget, click on "JSON" (a new window will open)
・in the new window copy the number after "ID": (53269 is mine for example)
・save this number, we will need it later
I tried several apps to add custom complications but the easiest one was Simple Complications.
・Download the app to your iPhone.
The UI is very barebones but it reflects the simplicty of the app.
・in the top field (URL) type BigBalli.com/purpleAir.php?id=53269 (replace 53269 with the sensor ID you copied earlier)
・select JSON and Often
・tap on Setup Data Source in the top right corner
・type aqi in the top field
On your iPhone, open the Watch App add Simple Complications as a complication on your watch face.
