well, now we are in full lockdown in Germany, and all gyms are closed. But until November, they were able to operate with a limited number of people training at the same time.

To make it visible to the members, My gym had a progress bar, being update as soon anybody entered or left the gym.

This information was available in their website. So I was scrapping this data and getting alerted (via telegram bot[1]) when the gym was operating under 50% the capacity and therefore avoiding wasting my time.
