hi there. i have been having mysterious PM 2.5 spikes on my Purple Air several times a day (usually from ~12 ug/m3 to 100 ug/m3!!). i recently figured out what is causing it: i live by a charcoal burger place that sends smoke throughout my neighborhood when they relight their grill at peak hours. it is what it is unfortunately, until these restaurants get properly regulated.

but i like to work in my yard, and id love to be able to just put on an N95 when a charcoal smoke event is happening. but i can't sit refreshing purple air all day either -- and the episodes tend to last about 20 minutes.

is there any software that would allow me to monitor raw PM 2.5 levels from the PurpleAir in real-time, and send a push notification when they exceed a certain threshold?

i feel like this type of dynamic background monitoring using the PurpleAir would be useful for other people too!

Hopefully something in there can help and fit with the time resolution you'd need!

these are very helpful, thanks so much!!

Thanks @bhamster for the mention.

After two years push notifications still work for me. Received more than 8k of them saving countless time by non constantly checking the map. I looked around for different options but found none satisfactory. They show AQI only or rely on background app refresh or are more cumbersome or show ads.

Mine has the advantage of being very lightweight once discord is installed. Can be improved though with in-app onboarding, custom message, variable frequency and more. I have not received the right push to implement it yet.

Also @eustatic contacted a developer some time ago. They may have an improved version available by now.
