I only use two simple values from one device on the GitHub. But this can easily be changed to make a very powerful dashboard for a web developer. Each GitHub has basic instructions. I can add more if anyone has questions.
I wrote a NodeJS project that queries the smartthings API for device values every 5 minutes and stores them to local .json files and serves them.
Then I wrote a SvelteKit website to display the values.
This should all be familiar for web developers.
