Hi there

I am a Visual Studio Web Developer and have recently started using Node Red and all is new to me.  
I want to pass a variable result using a URL such as [https://xxxxx.fred.sensetecnic.com/api/var/?weight=40](https://xxxxx.fred.sensetecnic.com/api/var/?weight=40) from another device and then get the URL via http get request and display it on a chart. If someone can be of assistance I would really appreciate it. I understand it should be very simple and short.

Kind regards

Like I said I'm a first timer, trying to figure out how everything comes together. I want to open the url for example

[https://riaan.fred.sensetecnic.com/api/var/?weight=25](https://riaan.fred.sensetecnic.com/api/var/?weight=25) on another device and then the gauge should display 25.

Thanks in advance

I'm not infront of my PC at the moment. But if you can copy from and paste into Node-RED it's in the correct format. If not please EDIT your post rather than posting again.
