Hi. As I am sure you can see, that data you posted has nothing useful for us to try and help you.
Could you capture the output data once more but use the built in "Copy Value" button so that usable JSON is copied. You can find this "Copy Value" button by hovering your mouse over the payload.
PS, please always press the `` code button in the forum post toolbar BEFORE pasting code - to ensure the code is not corrupted/formatted by the forum.

I would install the buienradar node in node-red.
You can get the values, run it through a change node with jsonata to average the data
example flow (requires [this node](https://flows.nodered.org/node/node-red-contrib-buienradar) to be installed)
