I am writing this article for those who think, whether it is worth it or not, and who are beginning to build their smart home, I hope it will help you make your choice. For those who think that I am not a programmer, I will not succeed, I too, although I have a technical (heat and power) education, but I have never worked in IT, I do not know a single programming language. The road will be mastered by the walking one. Let's start with the discussion of what a smart home is, take my word for it, it won't solve all your household and family problems, but it will definitely make life a little more comfortable. What is a smart home in my mind a year ago: 1. A beautiful tablet with a diagram of the house hanging on the wall in the hallway from which you can control everything in the house; 2. Control everything you can with your voice. Revelation in a year: a tablet is not needed, since it is inconvenient to run from the second floor to the first in order to control.For voice control to work well, you need to install a smart speaker in each room, when two of them are one. And when much more is a question. Now for me a smart home is something that works by itself without my participation, and does not require management. Everything that will be discussed further has been done by me personally, maybe you can do it differently, maybe easier and better. But this is the way.
