UPDATE: 01/10/2018

I have released Achoo beta version 0.1! Check it out at achoo.us. Also, check out the blog post about it. Most of the info below is now obsolete and will be replaced shortly as Achoo is now a web app for users instead of just a repo for devs :)

Achoo uses a Raspberry Pi to predict if my son will need his inhaler on any given day using weather, pollen, and air quality data. If the prediction for a given day is above a specified threshold, the Pi will email his school nurse, and myself, notifying her that he may need preemptive treatment. TUTORIAL COMING SOON

Prompted by this reddit post. Lots of great ideas in there.

Here's my Pi setup (obsolete as this is all done through the app now)

Blue button is for inhaler (first line of defense)

red button is for breathing treatment (second line of defense; use this one if his symptoms are really bad)
