Smart is not that I can shout at a lamp through a speaker, but that it behaves the way I would expect anyway.

That is still the main appeal of Home Assistant for me: not just making as many things as possible smart, but making them behave correctly on their own. Smart, to me, is not voice-controlling a lamp through a smart speaker. Smart is when lighting does not turn into full castle floodlighting at night, reacts just right during the day, and lets me think about the technology as little as possible.

Smart home was very clearly a Corona project for me, but not one that stayed a toy. The setup is mature, productive, and that is exactly what makes it interesting. You can plan a lot in theory and prepare things in a test system, but the really relevant edge cases usually only show up in real life. That is where you find out whether an automation is actually good or only looked good on paper.

I would still recommend a dedicated test system to every smart-home user. I have one myself and would not want to miss that separation anymore. But it does not replace production. Nobody notices as honestly as the real world at three in the morning that a light is too bright, a presence rule is too nervous, or some fallback logic was not actually robust enough.

There is also enough real scale behind it by now: 21 areas, 3595 entities, and 166 automations. That is why I am interested not only in what is technically possible, but in how a system like that can stay pleasant to operate over time. The writing here comes directly out of that. So not abstract smart-home ideas, but things built from real rooms, real sensors, and productive daily use.

I have a fairly absurd number of standards in use, mostly because I was genuinely curious and at some point had a lot of different things running productively. That is also why I am always interested in exchanging experiences. If you need advice, feel free to reach out. I do not only help occasionally, I also look after remote instances for friends.

At the same time, the fundamentals are already covered very well in a lot of great formats. Instead of rebuilding that here, I would rather point to people who explain those basics really well. One very good starting point is Simon Oberstedt on his Simon42 YouTube channel .
