Smart home - common system architecture
When I finally decided to tell Habra about my smart home - he was ready, and I did not know how to tell so much, and most importantly - where to start. In the previous post I talked about room controllers, but without a general idea of the role this thing plays in the house and why it is necessary at all - it all seems, to put it mildly, divorced from the context.
Better late than never. I finally understood my mistake, and now I will begin with what all books usually begin with - from the table of contents.
Structural representation of a smart home:
Separately, you can select:
I use DHT11 as temperature and humidity sensors, Foton-9 motion sensors.
Hallway:
In a black box with a green diode (for the battery) lock controller and automatic charging system of the battery.
In the case of the Dlink's switch is my room controller, it is plugged into the bus (the bus socket on the bottom right), the inputs / outputs are routed by DB25 to the terminals on the left, so that you can quickly and easily replace the controller, if that.
The DHT11 temperature and humidity sensor hangs on the bottom left.
On snot in the center of the photo you can see the semiconductor key, which controls the light.

Restroom:
There is the same room controller, plus a leakage sensor (right behind the controller), to the right of the battery is its self-charging board, to the left is a tricky counterweight system that blocks the water.
Klemnika room controller is not visible here, it closes the wall.

So, about what you can tell:
- Semiconductor keys
- Leakage control subsystem
- Touch buttons
- Stepper motor driver
- Room controller
- Bus controller
- Android app
- Widgets for Android
- Qt server side
- Script language for writing smart home algorithms, CELAC (Condition - Event - Link - Action - Command) system. You can call it the other way around - but I liked the name CALEC less.
- Node.js Web Server
- Web interface itself
Separately, you can select:
- Door lock subsystem (controller, reader, power)
- How is the power of the smart home in general organized?

Finally a couple of photos of the filling rooms:
