Http request help from web

Hi, I am very new to node-red, I am currently using it from homeassistant.

I want to extract the information from the web page of my solar panels as the current watts, in the first image I want to extract the information of the h2, in the second image I have started an http request to the page of the solar panels and then an html node to search h2, finally when I debug I get the line I want but not the numerical information.


Try span.generated-energy-value and set the html node to text from element.

Thanks for the answer but I still don't get the information back :frowning:

Post the payload from the http request node, so I can test.

okey let me change the pass

I'm sorry I wasn't understanding you, my fault.
