Hello! Im summarizing information of sensors information in South Korea. As a new user to Purpleair.com I wonder how can I count number of censors for indoor and outdoor for Korea. It would be great if anyone shows me the way to solve this question. Thank you!

@Ethan That’s what I want to find for. I appreciated you support.

@Ethan Hi, How do I know which updated number of total features corresponds to which area?

You should be able to refresh your page and the data will be reloaded fresh. Then you’ll only see one set of “updated features”.
