After some struggling, I managed to properly install webCoRE (I think). And, I went through the process of creating a piston on the phone app, and deleting it.
I think it would be easier to work on creating a useful piston from a browser. I can generate a code from the “Register a browser” button on the ST app on my phone, but plugging that code into dashboard.webcore.co yields only spinning tiles in the bottom right corner.
I’m obviously missing something. (and, am obviously a newbie).
Thanks for any suggestions!
