Need help from like-minded people to develop inexpensive smart home equipment?

Question

Arduino

There are thoughts, developments, and even the implementation of one of the iron modules live with firmware.
What's the catch?
The catch is that I'm not a programmer, and it's very difficult for me to do exactly the part with programming. Therefore, I am looking for like-minded people who, perhaps, would also like to build a smart home for themselves, they know how to program, but there are gaps in the circuitry. For my part, I offer help in circuitry.
The idea is that different modules are created on microcontrollers: light control, alarm, climate control, voice alert system, automation control, etc. All this communicates via RS485 with a central controller that already carries ethernet.
One of the modules is already ready, namely the light control for seven groups, it allows you to control the lighting both from switches and from a PC using a usb-rs485 converter, and read statuses. okbit.ru/blog/arduino/pervyij-modul.html , there are already thoughts on the implementation of the remaining modules and even circuitry has been developed, but I think that until there is at least a test solution for the central controller, there is no point in soldering further.
So, respond like-minded people, maybe there are those, in turn I will help in any way I can, otherwise it’s hard to master this alone.

Answer 1

The topic is very interesting to me, but I’m just learning arduino so far (I can’t help. While I’m watching the topic, maybe I’ll catch something useful for myself.

Answer 2

If I understand your idea correctly, then this decision is not for sale, but rather for myself, because. in any case, the Chinese are already doing this and you won’t overtake them for the price, because everything will be cheaper for them, and even if you do it cheaper, they will still do the same as yours, but again cheaper.
In any case, in essence, I can help with programming the central module, if it is on any atmega chip. As an option, there is a prototype of such a controller, only it does not work through ethernet, but through the blue tooth, because I don’t like to carry cables, and its firmware is also over the air.
Judging by the sketch, the first module is controlled via serial, which is not good, because you need to allocate too many ports for each module via serial and it will work sucks, you will need to redo the connection, for example, to i2cwww.instructables.com/id/I2C-between-Arduinos

Answer 3

It doesn’t work out cheaper for the Chinese for a very long time, the option is only then to order boards from the Chinese, cheap and cheerful, it works not for the series, but for RS485, that is, it will calmly pull 60 modules over two wires.
A project for myself and for enthusiasts who want to repeat.
For the time being, it is planned to make visualization through the central controller using Mazherdom.
Vitaly , if you are interested, then let's make contact, I will tell you in more detail?

Answer 4

1) A more convenient solution is to use the ESP8266, including for accessing the Internet. Two com ports, I2C, PWM, ADC, WiFi, etc.
2) almost any sensors do not require strapping (I connected everything that I could purchase).
3) now it is interesting to implement frequency control of the motor, in particular, I am interested in possible budgetary circuit solutions and to manufacture compact control devices for power heating and lighting devices.
4) if I am interested in the ideas of using automation, I can write software, develop algorithms for processing sensor signals and generating control signals.

Answer 5

Good afternoon. I have just the software part of the control system so far with a minimum of peripherals (more precisely, in the amount necessary to manage my home, for which it was originally developed), but the whole chain - from MK to the Internet / intranet. Might be useful. Links to sources and description on ernold.net/ssn

Answer 6

Hello! I'm doing a passing thing. MAX485+mega32. dht22 sensor, thermistor, clock on ds1307 and more. Power part on triacs and mosfet. Everything is still in development. We need to complete our exchange protocol.

Answer 7

foxvlad I’m interested in your proposal, I would like to try to take part, I’m slowly doing the same only for my apartment, there are some developments - I’m setting up the Raspberry Pi for the central controller, I can also tell the Chinese-Chinese strife and they are not all great. He is also a supporter of the RS-485 transmission protocol - but as mentioned above, there really is a problem with organizing the power supply of devices. One of the options, several power supplies for an apartment (house) should solve this problem, you can also drive 4 wires - 2 interface RS-485 + 2 for power (the only question remains is power). Unsubscribe if you still have a desire to do something. In turn, I will also support the opinion that turning on a light bulb from a smartphone, a Wifi kettle, a schedule for opening the door to the pantry is sadness, not a smart home !!!
