Smart home in a ready-made house - what is the best way to do it?

Question

Smart House

Friends, I read it, honestly :) But I still didn’t find an answer to my question, on which system is it better to make a “smart home” in your already finished home with repairs, without wires, without Rasperry Pi and other extreme sports, while what would the cost be sane.
I read a lot about Z-wave, it seems to be what I need, I looked at the prices for sensors ... a temperature sensor is 4000 rubles, I have a need to measure the temperature in all rooms, that is, for five rooms and a street, I will need to buy some temperature sensors for 24 t.r., not so much I liked this technology.
Of the tasks - a server (based on windows for example) or a separate controller with a web interface or something like that. Control from an android smartphone and based on scripts.
Features that I would like to have:
1. Sensors for temperature, humidity, light, etc.
2. Smart switches that can be installed instead of the usual
ones 3. Smart sockets that can be installed instead of the usual ones
4. IR controller for controlling "non-smart" equipment
5. If possible, something similar alarms on motion/door/window sensors
6. Possibility to write some scenarios for managing this household, without the need to write kilometer-long scripts in java or something like that.
Accordingly, all of the above with wireless control.
On what equipment / technology can this be done? Thank you.

Answer 1

A smart home starts from a million for the filling. And you want a canary for a penny that would be cheap and without Rasperry Pi and extreme bases. Do you include a server rack and a server in the price? This is already 150 thousand will come out.

Answer 2

If you need to do it once, reliably, and not worry about performance - Crestron. If you want to constantly dig into the code and change cheap sensors - then anything else)))
Only here in the finished house there will be a real difficulty. "Smart home" requires serious design at the stage of building / repairing the premises, you need to carefully think through everything. And when there is no way to stretch an extra cable, one way or another it will turn out to be pampering.

Answer 3

I'm afraid that for an acceptable amount it will turn out only with a soldering iron in hand and ferric chloride in a jar. I have seen several developments of this kind, but they are all in a semi-finished state, when you have to solder the piece of iron yourself.

Answer 4

We do it all the time on the Fibaro Smart Home equipment , a fairly obedient thing, minimal repairs, no wires.

Answer 5

extremely cheap, dangerous - Chinese modules with Ali.
cheap, but sometimes buggy - noolite
cheap, but strange - some sonoff is
relatively inexpensive - zigbee (but you have to write a lot of software yourself) expensive
, but it works - z-wave https://docs.google.com/spreadsheets/d/1ZpO5bMvB4T...

Answer 6

Now it’s cheaper to buy ready-made, here, for example, for Russia -, for Kazakhstan -
I didn’t forget the links) apparently on moderation or something)))

Answer 7

For your case, Fibaro makes its own products. And yes, you correctly found z-Wave, maybe others are cheaper.
But, if done qualitatively, then it should be planned at the repair / construction stage - to lay the necessary wires and control everything via KNX / DALI / Modbus, but accordingly it will cost a lot of money.

Modules are purchased up to the kettle. Inexpensive. Everything you listed is available for purchase.
Compared to Fibaro, a penny!

Answer 9

If a major solution is required, until the next major overhaul, then I think it is worth looking towards the KNX standard. Yes, it's expensive. But it's worth it.

Answer 10

You can see the Livicom system.
A decent wireless smart home solution with easy scenario setup, cloud server and smartphone control.
Supports up to 256 radio sensors. I think this is quite enough to realize almost any fantasy.
