Because home automation is very complex and there is only so much that can be done to make it more simple without eliminating capability. I’m not saying that OH can’t be made simpler, but it’s never going to be something a casual user is going to pick up and create a home automation system the same way they would write an email.
If the loss of capability in favor of simplicity is something you seek, there are several commercial options that might be a better fit for you.
tl;dr: what each and every individual user wants to create with their home automation system is completely unique and unique in radically different ways. There is no way to distill that down into a simple wizard.
I’ve asked about 15-20 times for people to review the new Getting Started Tutorial for OH 3. Hundreds to thousands of users of this forum have read my pleas. 0 newish users have volunteered to help.
We don’t get to “pick” a user and assign them a task. Such users have to volunteer. And no one has. So all we can do is beg and no one bothers.
About 80% of all the core docs have been written by three people.
Will you volunteer or are you like all the rest, full of suggestions but “no time to help.”
[Yes, I’m a little tired of seeing “you’re doing the docs all wrong” posts with no offers to actually help fix it.]
