Hi all
I am trying to use Grafana dashboard to show my Thingspeak data which is generated by a Microbit IoT device. The data logs perfectly to the thingspeak website, and the GET command works fine as I copied and pasted into a new browser and i got json data (channel is public).
However, when I try connect my grafana dashboard and add the JSON channel feed (through simple JSON a plugin), I get a error in Grafana (although it says connection established). The error is:
<!DOCTYPE html> <html> <head> <title>We're sorry, but something went wrong (404)</title> <style type="text/css"> body { background-color: #fff; color: #666; text-align: center; font-family: arial, sans-serif; } div.dialog { margin: 3em auto 0 auto; } h1 { font-size: 100%; color: #f00; line-height: 1.5em; } </style> </head> <body> <!-- This file lives in public/404.html --> <div style="padding-top: 50px"> <img src='/thingspeak_logo_white.png' width='200' height='35' style='background-color: #2f7eb2; padding: 10px;' /></div> <div class="dialog"> <h1>The page you were looking for doesn't exist.</h1> <p>You may have mistyped the address or the page may have moved.</p> </div> </body> </html>
I am using a windows machine.

I have this set up like this and it works:
1) Set up the datasource. In my case, I set up a new JSON API with this URL:
2) Next I created a new dashboard with the above datasource, the "Query string" set to "results=8000" and 2 queries
a) $.feeds[*].created_at
b) $.feeds[*].field1
Now I select a graph visualization and get this dashboard:
This is no different than the chart here:
So, can you provide more context on your use case for Grafana instead of the built in charts?

You can use Grafana Infinity Datasource for this purpose. Below screenshot is an example from and how to use it. This plugin also allows you to other formats like csv/json.
PS: I am the author of the grafana infinity datasource plugin

hi thanks for making such a great plugin! I had my data up and displayed in grafana in no time! i am wondering if you can help as I am only recieving 26-27 minutes worth of data displaying in grafana?
Is this to do with thingspeak only sending 100 lines at a time?
What do i need to do to be able to see more historical data than 26 mins ago?
All help appreciated
