Hello folks,
I’ve recently migrated from OH1 to OH2 using the OpenhabainPi image. I’m slowing moving from my old system to this new and now I’m starting to tackle the MQTT objects. I’m reaching out to the community because I can’t seem to grasp where to start using the whitepapers. I find that I can better understand how to work through these things on the forums.
Should I start with the Paper UI or just a text editor?
Here’s my current working (MQTT 1.x) items. I understand that I need to create a .things to create a broker and channels. I don’t understand how the channels and items work together.
Would someone help walk me through how to convert these?
