"Make something that doesn't exist!" What is the aim of "mania" who made the clinic home-automated by himself (Part 1)?

"Make something that doesn't exist!"

For example, if you want to make your home a smart home, you will probably want to use ready-made products from well-known manufacturers. Simply connect smart lights, smart locks, infrared remote control units, etc. to your home network, and then link with dedicated switches and smartphone apps. It's really easy.

However, there is a limit to what you can do because it is easy. Even if I'm not satisfied with my ideal use and want to do more, it may take too much time to realize it, or it may not be possible in the first place. Know what you can and cannot do with the product, and then compromise what you can't do. That should be a general feeling.

Some may think, "If you can't, you can make it yourself." If it can be solved by building a small script or program, it is worth the challenge. However, it is rare for people to rush to "make everything" just because there is no ideal software or hardware. Even more so, when it comes to personally creating a large system called home automation (HA) ...

With such a light-hearted feeling, "Then, make everything", a fierce man who turned his own clinic into HA on his own appeared. Moreover, he said that he is considering general sales from around June 2019, saying, "If you make it, let's make it sellable." What kind of system did you build? This time, I would like to visit the clinic and tell you the whole picture of the HA system that I saw locally.
