  Yes, that is possible with our gcode/server commands using a custom dialog and
  

  • http_get(url)
    Sends a simple GET query to the url. The response is stored in a json object string with the fields code for the status response code data for the response body. Normally a positive answer has the status code 200.

  computed expression. With this you get the result and can store it in a variable that you then show in a dialog. Be aware that in contrast to @webaction this is a blocking command - means until we get the answer the server can not send commands to printer! No problem beside a print or when the sensor is available and answers quickly.

  Thanks a lot, I am glad that this is possible. Well, it really is to check quickly the weight of the remaining filament on the spool and to get rid of the necessity of a separate LCD (space and design concerns...). So it would be sufficient to have the value displayed before the print starts. 
  
  Would you mind pointing me a little bit more detailed in the right direction on how to implement that, please?
  
  Thanks a lot!

  Best is to write it as wizard or quick command. Completely untest, just to get a feeling.
  
  @set global.spoolWeight {{get_json(http_get("http://192.168.1.22/your_url"),"/data")}}
  

  @dialogStart "Spool weight: {{global.spoolWeight}}" "Weight"

  @dialogButton "Close" 
  

  @dialogShow
  

  
  First line queries the url and gets a json object where the content is in data field, which we extract with get_json and store it in global value spoolWeight. The rest is opening a dialog and adding some text including the spoolWeight value.
