Greetings,
I thought I would share my first SmartApp that pushes temperature updates to an Adafruit IO Internet of Things feed. This then allows you to graph multiple feeds on a dashboard. I saw enough people asking in the forums about how to graph temp history that I thought I’d share my project. It’s really simple and it was fun to learn how to make a SmartApp.
