  1. Your tutorials, especially the accompanying videos, are wonderful. I’m a retired computer engineer and still love exploring IT. I have a fairly extensive knowledge of many aspects of IT but I am no programmer!

    However, Node-Red and MQTT have helped me mitigate my limited programming skills. One aspect of Node-Red I am struggling to fully understand is version control within projects. I’ve managed to commit changes both locally and remotely but can’t see how to revert to an earlier specific commit. It would be great if you were able to create a tutorial on this subject.
