PurpleAir Air Quality Station for Hubitat and SmartThings

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).

To use this Air Quality Station in SmartThings, you will need to:

1. Create a new SmartThings device handler or Hubitat Driverusing the supplied source code

• This version auto-detects the host platform, so no further editing is required.

2. Create the actual device:

• SmartThings: log into the IDE, select your Location, select Devices and then select Create New Device
• Hubitat: Simply create a new Driver from the main menu

2. Specify your preference for update frequency
3. Specify the desired PurpleAir Station ID you want to monitor

To find a specific Station,

1. Use the PurpleAir Map to locate a station (https://www.purpleair.com/map)
2. Open this URL in a new Window or Tab: (https://www.purpleair.com/json)
3. Search for the NAME of the station you found in step A
4. The Station ID is the first element in the results[:] map - you will enter this ID (1-5 digit number) into the preferences for the Air Quality Station

That's it - save, and you should be up and running!
