Then you need to write them. I’ve been working with openHAB for near on a decade. In that entire time I’ve dedicated myself to helping new users get started with openHAB. I’ve written scores of tutorials. I’ve written more than half of the Getting Started tutorial.
Yes, I have lots of experience with OH. But I have even more experience helping new users get started with OH.
I’ve even written end-to-end tutorials. Heck, the Getting Started tutorial is an end-to-end tutorial. Here are some more:
Dozens of users have written hundreds of other tutorials and posted examples. Some are point and some are end-to-end too. Solutions - openHAB Community
There are lots of resources outside of this forum and the docs too. See How to get started (there is no step-by-step tutorial) where I collected a bunch of them.
Examples we have coming out of our ears. What we don’t have is an end-to-end show me everything using my specific technologies X, Y and Z. That’s not feasible. There would be 350! (that’s factorial) different tutorials just to cover the different combinations of add-ons alone. That wouldn’t even touch Items, the UI, Persistence, etc.
So what we do have are point examples. We have examples that document, as @StefanL38 called it, “the pattern” for how to do something in OH. But you have to be able to take that tutorial, extract the pattern, and apply it to your specific bespoke situation and goals.
And if that isn’t good enough, anyone can step up and see if they can do better. Demanding that other people donate their time to document things exactly how you want isn’t going to get you anywhere. We’ve all already done the best we can. If it’s not good enough, step up and show us a better way.
