Hello, and thank you for taking the time to respond. To be honest, I didn’t understand your tutorial at all. I’m an absolute beginner, I have no knowledge of JSON, or REGEX or OpenHAB 1.x or OpenHAB 2.x or even MQTT. All of this is new to me. I honestly don’t know how to translate what you mentioned in the tutorial into what I need and want.
I’m just trying to figure out and build on top of what I already know, based on this tutorial.
