Ok … I have got a basic understanding of the DSL Rules and got HABApp working (thanks to Sebastian) … I am going to focus on JSR Python following Rich’s post [Journey to JSR223 Python 1 of 9](https://community.openhab.org/t/journey-to-jsr223-python-1-of-9/78556)

At this point, staying within OpenHab will probably allow me to learn more before I take a plunge into HABApp.

So far I have found that its hard to follow the documentation since there are so many platforms to support and evolving concepts … one needs to work carefully and have low expectations 🙂 for quick progress.
