I think it is both: a tool building it and if it is build using it.
I agree with this.
Sure this works. There are initial steps that have a certain pattern and regardless if somebody uses
Somfy, whatever brand wallplugs, whatever smoke-detectors, whatever brand onewire-sensors, whatever brand hifi-equipment there will be differencies in details like what kind of options, how many channels etc. etc.
But there is a underlying pattern that is the same for all of them.
And there is a sequence of steps in a certain order that is the same for most of them.
If you are trying to tell me there is no common pattern at all OpenHAB would be the most complex, irrigating non-useful software ever programmed (except maybe brainfuck)
I want to emphasise I don’t believe this. OpenHAB is a very flexible and versatile software-system.
Though learning it can be more efficient than “Try and Error - clicking, this clicking that reading here reading there” on a small system
The more efficient way is to show it on a small system with more or less typical components like some light-switches and something simple like a thermostat which have a small number of adjustable features but still enough to show the basic principles.
So here are some specific questions:
