Imho everything became more complicated when the devs tried to make things easier.
The moment hassio came out everything became very fragmented, and people can’t follow half of the old guides because they only work for an ‘old fashioned’ homeassistant install.
The moment the automation editor came out the forums were filled with messy automations that don’t work and can only be fixed by going ‘back to basics’ and changing the code the ‘old fashioned’ way.
Each of these things are getting better with time, but it makes it harder and harder for people to find what they’re looking for and get a fix when something doesn’t work.
Back in the ‘old fashioned’ days there was one set of instructions, a quick learning curve for the nuances of yaml, and off you went. If you couldn’t make it work, you came here and somebody could fix it without having to ask you several questions about install methods and/or trying to rearrange your code just to make head or tail out of it first.
It’s just the stage it’s at really.
