Here’s something I wrote to learn the platform. It ain’t fancy, but it does what it’s supposed to.
All it does is keep a list of what presence sensors have arrived since the last time any of a list of doors have been opened, and then greets them by name. I was previously doing this with CoRE, but I had a heck of a time getting the logic to welcome more than one person at once. This app will do that, e.g., “Welcome home, Bob and Alice!”
Let me know if you’d like to see anything else in it!
