Scrape Informations combined with a Restful sensor?


I want to scrape some informations from this site: ChargeFinder - Ladestationen für Elektroautos.

I want to have the informations in my ha, if these charging stations are available (“verfügbar”) or currently blocked (“belegt”). It seems, with normal scraping I cant make it work. Am I right in my assumption that it doesnt work because the informations are shown with javascript? Is there a way to get this informations in any other way? I read some things about Restful Sensor, but Im not skilled enough to even test this. Any ideas?

Just a suggestion, why use that particular site when you could use others that have APIs? Even have built Home Assistant integrations?

You could extract info from OpenChargeMap just like this one does.
