Smart Home Wiring: Ethernet, Alarm, SAT, Wired vs Wireless Systems?

Question

Hello, I will soon be converting the installation from 2 wire (1988r) to normal. As forging is unavoidable - I would like to add other installations as well - alarm, SAT for a few rooms, Ethernet, and maybe a control for the Smart Home. What's worth doing? Maybe some other ideas still? Give Eth...

A wired system is always better than a non-wired system (wi-fi can be easily interfered with and bandwidth through walls decreases considerably). For this reason, you should have a twisted pair of cables for each light outlet in the room (for future remote light control), plan the sockets of the comp network and pull the twisted pair of cables there; you can also isolate one circuit for maintaining the network and put lighting on it (not the whole circuit, but one lamp per room), some sockets e.g. for a computer, router, refrigerator. Give the UPS-SIEC switch at the beginning of the circuit, then a normal power supply and a differential. And to the UPS only a normal circuit breaker and from it to the switch. This way, if the UPS fails, you can switch to the normal power supply, and if the power supply is OK, it will go through the UPS.

It is not that simple or obvious. Such installations can be done in a number of methods and probably everyone speaking will have a different vision.

As far as the alarm installation is concerned, it is really worth asking the installer for support. The placement of detectors (and therefore the pulling of cables to specific points) is not so obvious or trivial.

As for Ethernet - I'm in favour of bringing all the cables to one central point. A switch, a router and that's it. Here, you need to anticipate the number of devices in individual rooms and only to this .... cables. Plus cables to APs where necessary.

Now the house automation. It's best to make the insallation for a specific automation. If not, then I suggest bringing all the circuits to the switchboard where the automation will be, and from there to the next switchboard where the circuit protection will be.

That's it in a nutshell. If you think you can do it yourself and it will be fine, you are wrong. I've already made a few mistakes thinking I know what I'm doing, and in fact I've only just now figured out how I want to do it, which I've described in a few sentences above.

One ideal would be feed-throughs (channels) to allow for future additions of e.g. TV cables, additional Ethernet cables, etc. This is because sometimes the purpose of a room changes (e.g. growing children) and a problem arises because "you have to put a switch" or "pull the cables behind the skirting boards". It doesn't happen often, but still...

So much in a nutshell.

. Holy crap ! . And so you end up putting a switch in each room - that's another Holy Truth . . It's not like that. I myself am at the stage of ditching from basement to attic of an old cottage, and I wonder if my great-great-great grandson will use Wi-Fi to open the gate or perhaps the Force of the Jedi Knights. . It's worth thinking about so that changes and modifications can be made without having to re-do the whole cottage. And that's really where the difficulty of the whole installation operation lies. Therefore ... . It is worth thinking about wickets that allow changes and modifications to be made. This allows you to use one system today and something supposedly more modern or(and) completely different tomorrow. A system is one thing and preparing a house for modifications without demolition is .... another matter. By the way Link . P.

Quiet! At least it will have an order at the beginning .

It looks like the one koelga wrote @Erbit in #3 Regarding inspiration, let me toss in two topics for you to read. One completely loose, a bit of fun by our colleague @marek216 and a second one where not only the individual installations are discussed, but also how they are interconnected: It is one thing to be inspired, but it is quite another to install an installation correctly, in accordance with the needs and the existing conditions.

I know from experience that only a star topology.
central point allows for order and upgrade. it is also easier when professional help is called for. the wires are labelled and everything is in its place. working in such a house is immediately easier.

You don't have to use lan at all and rely solely on wi-fi, but you always have a less fail-safe solution. If you are talking about unavoidable forcing, then maybe you could run it along the façade? unless you already have insulation, then that's a bummer.

The worst thing about all this is that the lack of cables will be a limitation later on. That is, if you don't foresee something today it's a problem later. Here you also have to bear in mind (when renovating) a possible intercom (and intercom installation inside - I have two devices on which I can receive the intercom omitting of course smartphones), cameras (and installation inside) although exactly these two installations today are quite easily built based on Ethernet. So again, I find that a central point (star topology) will make it easier to use and possibly expand.

Ethernet - star topology as much as possible, but I can't predict how much equipment there will be in the future and whether this technology will be used at all in 10 years' time, so 1 socket, and you can always make 2 sockets out of 1 cable - or eventually a switch.
Alarm installation - also, although if you run 8 wires, you can connect several detectors on 1 cable. My house is not a fortress and I am not a millionaire...
Electrical installation - star topology is too many wires for me - especially lighting, of course, the kitchen has several power supplies, bathrooms separately, but the rooms do not need separate ones - not much power-consuming equipment now.
Intercom: taking advice I think I'll do eth + 8 strands of alarm, we'll see what comes in handy.

retrofood · Answer

. It is only in this central point that you need to provide room for expansion . Because in the frenzy of planning, the concern not to forget anything, somehow it usually escapes us that this mythical focal point likes to be quite large after all. And after all, it must not be an ugly hindrance to householders and non-household alike.

I'm sorry that I got out of the way with this help. My colleague started something about a smart house and alarm cables to each window, so I thought (wrongly) that we are talking about a properly made installations and not such a DIY, just to be

. Something Krasicki once wrote about this . Anyway... many of us (myself included) think that ... know better. Unfortunately, this way of thinking is most often due to ignorance (and I know this from autopsy). Only later it turns out that it was others who were right . Or then the alarms go off at night or, as in my neighbour's case, it howls for no reason and no one actually reacts to it anymore. Well... maybe only a thief will react one day. [edit] . Unfortunately (for me unfortunately) I confirm. I seem to have anticipated but ... not enough .

. Do you think Ethernet will share the fate of the wire phone ? Taking into account some advantages of wires such as the difficulty of jamming the signal and the speed of transmission it will probably be used for some time yet. . And this is usually the most difficult part. After all, usually even in the design of a new house there is room for a boiler room but but the designer rarely thinks of a server room. Well, maybe only when the building is designed from A to Z with an IQ slightly greater than a pine cone. And if the house is from the pre-Internet era, the larder is at most usable. To the Author. The installation should be, as they say, prepared for all possible and the most imaginative of all possibilities. Costs are rising, but who knows if at some point in the future there will be no installation of roller blinds, window detectors, intercoms in a few places because children grow up, etc. etc. Of course, it is not necessary to install all the devices at once, but ... In the event of a W, the cable is already there and is just waiting. The more cables, the less Wi-Fi, although these days it is probably although nowadays it is probably easier to have Wi-Fi than cable options. But that's just blah, blah because the reality ... is quite different. Thus, a cool topic but very, very difficult because there is no ready recipe. P.

Me on the subject of forging and puttying.
Regardless of what you choose it's a good idea to lay down conduit for switches and sockets depending on the construction of the house.
Just straight pieces from the box to the floor. If you need to add a cable in five years' time, you can simply run it through the cable duct to the floor without any drilling and it will still be there. Maybe you can hide it behind the plinth. Forget that you will be able to run a cable through a conduit that has some kinks in it. It's a myth.
In my house, I have a wooden ceiling where all the cables go. The attic is not in use and the floor is covered with OSB.
I also recently needed to add a new cable and the fact that he has sunken grommets in his boxes helped a lot. I simply unscrewed a couple of boards and laid the cable and inserted it into the grommet from above. No forging.

And now for a bit of a different story.
If you don't know what system you're going to use now, then choose a star and lay 5 x more cables than you originally planned.
My opinion is that if someone doesn't build a system from the beginning but prepares for the future, he or she will end up with kilometres of unnecessary cables in the walls, because the probability that he or she will start to destroy an existing and working installation in the name of some kind of automation is small.
