I suspect you are attempting to access the values on the page?

The request is recieving 5700 characters because that is exactly the size of the HTML

HOWEVER - the html for `http://alloy.geocom.cl/` does NOT contain any of the data - the data on that page is populated via a SCRIPT and the data actually comes from `http://alloy.geocom.cl/xml/dynamic/merge.xml?svTrack=&dataLogger=&ioConfig=&power=&conn_status=`

e.g...

so if you instead access that URL and convert from XML to JS object, you can access all the values (and there are lots - happy hunting)

Demo flow...
