PHP Scaping data from a webpage

I have tried a couple of things for trying to scrape data from the following page https://app.hotspotty.net/hotspots/11euSptu1Ee3HgDCMfepYELwWMGMqkNdD9DQJqKbzPkasFebGne/rewards i am interested in fetching the rewards for yesterday so i can set an alert if it reach zero like it is now…

due to then the hotspot might be offline due to low power or something else that needs an operators attention.

i have tried curl, simple_html_dom and file_get_contents(‘https://app.hotspotty.net/hotspots/11euSptu1Ee3HgDCMfepYELwWMGMqkNdD9DQJqKbzPkasFebGne/rewards’);

For some reason i havent been able to fetch any data from that page…

So now i ask you experts for some help and guidance, what is the best way to monitor the activity yesterday for that webpage?
