The downloaded PurpleAir CSV files associated with my three sensors are no longer being populated with the requested readings. The file is created and the column headers and date appear but the time is midnight UTC and no sensor data is listed, just blanks. It makes no difference what averaging period is requested; i.e., 10 to 1440 secs. I recently needed to change my gmail account password and went through the process of re-establishing a PurpleAir account thinking that may be the problem but apparently not.
Has anyone had a similar experience or thoughts on what may be happening? Any ideas would be appreciated.
The new PA download tool from the map is much worse than the old one.
Now you can only download one parameter at a time and for limitied times,
depending on what you have graphed. For example, its impossible to look at conversion factors without doing multiple downloads for temp, RH, CF1, CFatm, etc. And if you want 2 minute data, you can only get a few days at a time. PA used to have a great download that “democratized” access and availabilty of air quality data. I think you are risking your lead in this, but making the data much harder to get.
Hi @Dan_Jaffe, we are still working on providing more extensive download tools in the future. The new graph download tool is a minor feature to help provide data to those who don’t need as much or only handle small amounts of data at a time.
