Thank you, I stand corrected!

"Capable of drawing 28,000,000 watts of power" doesn't tell us anything. As was noted, it should've been given in megawatts (28 mW) or kilowatts (28,000 kW). Clickbait aside, how many kilowatt-hours (kWh) does it actually use?

28 mW isn't that much energy, relatively speaking. As of 2015, Forbes estimated LV uses 8000 mW on an average summer day.

The potential is impressive. I doubt it pulls anywhere near that. Unless I did my math wrong, this seems sensationalist.

Is there a way or an app to automate that?

Sadly, not to my knowledge. It's an app-by-app process. I could see an Ansible play or similar potentially fulfilling such a role, but I'm not aware of any existing projects.

I use Heimdall and Portainer myself, and I'd recommend them both. Portainer is for keeping a visual on Docker and/or Kubernetes containers, while Heimdall acts as a "home page" / front end for your various web GUIs (incl. Portainer).
