3r3173. 3r3-31. A smart house, quite a hackneyed topic in our time and in this publication I will not tell you about new technologies, manufacturers and current trends of this topic, everything is written to me once a hundred. I will try to briefly describe the process of creating a smart home (hereinafter UD) without deep technical narratives. If this topic is of interest to readers, I will lay out completely all the listings of programs, MK firmware, diagrams and everything needed to make this miracle the heart of your home. 3r3-33160.  3r3173.
3r3-33160.  3r3173. The main concepts in the development of a DD are the complete absence of a “collective farm”, in other words, the electronic stuffing should not stand out aesthetically (ordinary sockets, switches, light bulbs) and not burden users (duplicating the main functionality in usual ways: any light source can be turned on either from the switch and from the phone, and not as with smart lamps, who is in the subject, he will understand). I will even apply the picture for clarity: 3r3-3160.  3r3173. 3r3-33160.  3r3173. 3r3-33160.  3r3173. 3r3-33160.  3r3173. Last addition and with the lyrics finish. I could buy a ready-made smart home system, but in the recent past I was well versed in circuit engineering, electronics, programming, and I had a car of time, and at that time I started building a country house that I really wanted to endow with a brain. In general, this is how to ask the fisherman why you fish if you can go buy it! For the pleasure of the guys, for the pleasure, the understanding that you can automate your home, and put your soul, your ideas, your logic in it, really makes your home somehow alive. Let's go! 3r3-33160.  3r3173. 3r3-33160.  3r3173. First of all, I determined the DD functional that is really needed:
 3r3173. 3r3-33160.  3r3173. 3r361  3r3173.
Control of all light sources, both from the switch and from the application 3r370.  3r3173.
Lamp brightness control
 3r3173.
Various lighting modes: automatic shutdown, presence mode, light in the night - this mode I thought up when you turn it on it lights up your way at night to the toilet. You do not iron your hands on the wall in search of a switch, you can think of something else.
 3r3173.
Control of certain sockets where the iron, curling iron, hair dryer, hob, etc. is connected The ideology is as follows: left, forgot turned it off or not, turned it off through the application.
 3r3173.
It follows from the previous point that it is necessary to control the house from anywhere in the world and a lighttense remains:
 3r3173. 3r3-33160.  3r3173. -Temperature and humidity in the house, on the street and in the basement 3r3-3160.  3r3173. -the temperature and pressure in the heating system (private house, nowhere without it) 3r-3160.  3r3173. -protection against leaks, smoke, even more precisely not protection, but notification.

From words to deeds

3r3-33160.  3r3173. Split the system into three blocks: 3r3-3160.  3r3173. 3r3-33160.  3r3173. 3r361  3r3173.
The control unit lighting and power load 3r370.  3r3173.
Monitoring unit (various sensors) 3r370.  3r3173.
Mini computer (Primary Brain, OS server core, .Net)
 3r3173.
3r3-33160.  3r3173. 9-channel light and power load control unit 3r3122. 3r3-33160.  3r3173. 3r3-33160.  3r3173. The basis of MK from Atmel atmega1284 is no arduino, only hardcode, only C, the ethernet module ENC28J60 was selected as the communication channel with the brain (UART is boring, limiting the length of the wire, even hangs on fumes), a few words about the ENC28J60 module, in fact, a dubious microcircuit : errata has more datasheets, but for the month of work it has never hung up, so for now I have no complaints about it. He promised without technical narratives, but this is not floor cleaning, completely without terminology, nowhere. 7 switches are connected to the unit and, accordingly, 7 lighting devices, two channels go to contactors of 25A each, one to the outlet where the wife strokes my trousers for work, and the second to the nursery, there are two for parallel sockets. First, I collected everything on my knee in my lab 3-3-33160.  3r3173. 3r3-33160.  3r3173. 3r3-33160.  3r3173. 3r3-33160.  3r3173. Grass board method LUT 3r3-33160.  3r3173. 3r3-33160.  3r3173. 3r3394. 3r3-33160.  3r3173. 3r3-33160.  3r3173. 3r3-33160.  3r3173. 3r3-33160.  3r3173. After the board was tested for operability, I ordered several copies of the circuit boards in Novosibirsk, 3-333160.  3r3173. 3r3-33160.  3r3173. 3r3108. 3r3-33160.  3r3173. 3r3-33160.  3r3173. I collected two copies of the control unit, one to test the loads of the second already for installation in a country house. It is terrible to install equipment in a house that is not sure. Each channel in theory withstands a current of 12 amperes, but 2-3A is enough to illuminate or control the contactors. No matter how I tried to burn the test board, I did not succeed, I even connected a 3 kW heat gun, the triacs warmed up almost to red, but none of them failed. Summarize the board passed the test as well as possible. 3r3-33160.  3r3173. 3r3-33160.  3r3173. The microcontrollers on the board were programmed and installed in the house, the light could already be turned on through the switches, but the smart house still did not smell. 3r3-33160.  3r3173. 3r3-33160.  3r3173. [b] Mini computer 3r3-33160.  3r3173. 3r3-33160.  3r3173. At work, I discovered a thin client with 1GB RAM and 8GB ROM, on Amazon, the price for it is slightly more than 100 bucks. I chose Server Core as the OS, because I am a C # oriented person). I don’t know how to write native software for android and apple and for a long time I decided for myself that my bot on the Pashka Durov platform would manage the smart home (Telegram who didn’t understand) for a week I sat behind the laptop under spaten and the bot is ready. It's nice to work with smart people, this is me about telegrams, the bot was written in one breath, clear documentation, working libraries, no glitches. One well-known sad moment: the Roskomnadzor wants to block the cart with all its might, and it works on smartphones as it worked, but with the bots the situation is slightly different, they connect to the servers one time and in order not to tempt fate I picked up on AWS (Amazon Web Services) openvpn server (and for free, in the Amazon there is a payment for the traffic, and the traffic through the bot is minimal). After downloading, the thin client connects to the vpn server and, already bypassing all Roscomnadzor blocking, quietly processed requests. 3r3-33160.  3r3173. 3r3-33160.  3r3173.
The result is 3r3-33132. 3r3-33160.  3r3173. The system works for a month in real conditions without a single glitch. In the telegrams on the android there is a bun that you can bring the bot directly to the desktop and open as a separate application. Yes, I am far from being a creative person and called the bot Jarvis
 3r3173. 3r3-33160.  3r3173. 3r3-33160.  3r3173. I am very pleased with the bot and there is simply no need to write native software for mobile devices 3r-3160.  3r3173. 3r3-33160.  3r3173. 3r3-33160.  3r3173. Some information from the monitoring unit 3r3-33160.  3r3173. 3r3-33160.  3r3173. 3r3-33160.  3r3173. Ask questions, I repeat, if the topic is interesting, then I’ll post all project sources on github as well as all the schemes so that you can, like KIT, put the firmware in and fill it up with a bang without much knowledge of programming and circuit design.
