# How do I import changing/dynamic data on a webpage?

A remote device (sensor) is sending measurements (that I get in JSON format) to a given URL and is sending new measurements (data points) every couple of minutes. I cannot share the URL but the originating sensor is an air quality sensor (see https://www.purpleair.com/map?589048#11/18.0825/-67.039, as an example; note that the data I am getting is NOT the same as this example). Here is an example of data that I am getting at the URL:

A new record (like this one) is added to the bottom every 2 minutes or so

How do I import this streaming data into Mathematica. Here is the output I get from URLExecute[url]:

Websocket not connected - no realtime data will be shown!

• Can you provide an URL that behaves the way your server does? Can you share the code you are using to connect, including your URLExecute call? Put yourself in the position of somebody trying to help you. What information would you need to reproduce your problem and find a solution? That, YOU should provide in the question. Please edit your question and add more context. – rhermans Jul 11 '19 at 9:30
