PurpleAir Air Quality Station v1.1.01, updated on March 28, 2019
This DTH provides continuously updated Air Quality Index based on the PM2.5 data supplied by a Purple Air air quality sensor (see www.purpleair.com for more information).
Now automatically supports both SmartThings and Hubitat - no edits required
Now supports PurpleAir “Inside” sensors (with a single laser)!
Simple Setup
To use this Air Quality Station in SmartThings, you will need to:
Create a new SmartThings device handler using the supplied source code
Create the actual device: log into the IDE, select your Location, select Devices and then select Create New Device
Specify your preference for update frequency
Specify the desired PurpleAir Station ID you want to monitor
1.1.01 - Automatic support for both SmartThings and Hubitat|

Thanks for this. Does it work with the indoor sensor as well? I can get it working with my outside one but I want to turn on air cleaners etc (nor cal) based on indoor air quality. I set the indoor one to be public in case that was the issue but still have not been able to get it to work.
I am able to find the ID. The differences I am aware of are the indoor sensor has only one laser and also has a color changing LED to indicate air quality.
Do you mind sharing with me the ID # of your internal device? I’ll have a look at the JSON it is providing and see why it isn’t making it through my code…
FWIW, I use FooBots for my internal Air Quality Sensor, and it has direct integration with Nest & Ecobee to run the fan when it gets yucky inside. That said, I don’t think it ever has actually turned on the fan (my house is pretty tightly closed up, with HEPA 15 filters in the HVAC…
I could be wrong, but it looks to me like that FooBots mentioned up above does a ton more than just simple particle detection and it is only $200. What am I missing?
Obviously, I agree that the Foobot is better for indoors, and PurpleAir for outdoors, since that is the path I’ve taken. There is a SmartThings DTH for the Foobot as well, although it doesn’t use the same AQI Scale.
The only thing missing is that neither Foobot nor PurpleAir provide (true) CO^2 measurements (Foobot’s interpolate abs estimate).
Foobots is meant for indoor air quality. PurpleAir for outdoor. If you live in the Western US these days, and you have people in your family with lung issues. You know the value of having good outdoor air quality readings. (as well as indoor)
Barry (@storageanarchy), I’m using your DTH for a webCoRE piston that displays the AQI/PM values. However, when retrieving the AQI and PM data, any trailing zero (0) gets dropped from the retrieved value. For example, here’s a screen shot of the piston’s status page with the AQI10 and AQI24 values of 3 and 2, respectively … they’re supposed to be 30 and 20:
This also applies to the retrieved PM data, but is doesn’t really matter (to me) since it’s dropping the zero (0) at the end of a decimal number.
For a quick fix (I haven’t found the time yet to thouroughly look at the code), I temporarily changed (back?) the AQI attributes from ‘number’ to ‘string’ in my local copy of the DTH. The following example screen-capture now correctly displays the AQI10 value of 30, in this case:
