I recently updated my Openhabian from 2.5 to 3. I really like the new Website but I feel like I have to learn everything from scratch again (And I was just getting used to the 2.5 GUI).
But my reason for making this post is something different. I have the used RRD4j in OH2.5 to create Charts of multiple MQTT Temperature Sensors. But when I try to make the same in OH3, the Charts remain empty. Is there some settings I am missing or does my changes made in 2.5 (Creating a Persistence) interfere with the OH3 Features.
