How to set up custom AQHI notifications

What are Custom AQHI notifications?

Custom AQHI notifications alert you when your chosen AQHI value has been reached or is forecasted, so you can take steps to protect yourself and those in your care from the effects of air pollution. You can set up notifications in the WeatherCAN app in a few simple steps.

How do custom AQHI notifications work?

You can set custom notifications for your unique risk level, depending on your sensitivity to air pollution. The notifications alert you when your chosen AQHI value has been reached or is forecasted for your selected locations.

You can turn custom AQHI notifications on if they are available for your chosen location. By doing this, you will get AQHI notifications for the current conditions and for the forecast. Notifications will also be sent when:

  • The current AQHI conditions or forecast have reached or exceeded your custom value compared to the previous hour.
  • The current AQHI conditions have decreased below your custom value in the previous hour.
How often will I get custom AQHI notifications?

AQHI notifications are sent based on the number of locations that are turned on and the value set for each location. Current AQHI conditions are updated every hour and forecasts are issued twice daily at 6 a.m. and 5 p.m. local time, with updates as needed. You can limit the number of notifications by reducing the number of locations turned on or increasing the value set for notifications.

How are custom AQHI notifications different from air quality advisories?

You receive Special Air Quality Advisories for your saved locations when there is a high level of health risk to the general population (the AQHI reaches 7). The custom AQHI notifications feature allows users to set notifications for any value between 3 and 10+. This is especially useful if you or someone in your care is sensitive to air pollution.

How do I choose the correct AQHI number for notifications?

You should choose your AQHI number using your own experience and symptoms as a guide. If you are sensitive to air pollution, you may want to set notifications for the moderate risk category (4 to 6). If you are not sensitive to pollution, you may only want to set notifications for when AQHI reaches the high-risk category (7 to 10).
