ᐅ General: Network, TV cable, bus system

Hello dear community,

we are planning to buy a house, preferably an energy-efficient House 55. To be clear, we are still searching and currently have nothing fixed.

However, I am already thinking a lot about topics such as the home network, home bus system, and TV wiring. I have searched a lot online, but many questions remain. I now have some questions and hope you can help me with your experience:

Home Network
  • Which cables should I install, considering future-proofing? Cat 6 or Cat 7?
  • How does it work with the cables? They are bought, for example, on a 100 or 200 meter (328 or 656 feet) roll. Do connectors need to be attached afterward?
  • How are the cables connected to flush-mounted sockets?
  • The central point should be the basement. Everything should come together here. Do you use a patch panel (which I have never heard of before) or a router with switches? Internet will be provided by a cable provider. Would the installation then be as follows? Wall socket in the basement --> cable provider’s modem --> router --> patch panel --> flush-mounted sockets?
  • How are the network cables actually routed? One cable from the patch panel to each flush-mounted socket? The sockets should each have 2 ports. Or do you have to run 2 cables per socket? IMPORTANT: At least gigabit is required everywhere, preferably 10 Gb! If you assume one cable per port, that will result in a lot of cables.
Home Bus System
  • Our house should also be future-proof. I keep reading about KNX/EIB bus systems for homes. Can you recommend them? I am thinking, for example, of programming lights and monitoring and controlling the heating and ventilation system.
  • What do you think of the company GIRA (KNX system, sockets, etc.)?
  • For security reasons, I do not want the home bus system to be connected to the Internet. I do not need to control the heating via the Internet, etc. Is something like this possible (a private home network)?
TV Wiring
  • TV wiring is actually related to my questions about network installation. What kind of cables are used here?
  • Is one cable installed per socket?
  • How is this implemented if you have a satellite dish with one LNB? Can the signal be distributed throughout the house? Can everyone watch what they want? Or is additional equipment needed?
Sorry for the many questions, but I need to close my knowledge gaps step by step.

Thank you very much for your help.

Mate, not bad Steffen. So you’re probably active in the hi-fi forum too, right?

All those abbreviations don’t mean much to me at the moment, I’ll have to Google them at home.
How does the “you’ve got mail” thing work?
My wife will kill me if I tell her... She says I’m already involved in too many forums, and it just makes everything more expensive.

The "you’ve got mail" topic relates to smart home systems. But definitely don’t browse around that forum here. If you’re interested, check out the KNX forum (Google it! There’s only one major one). “You’ve got mail” is actually a pretty "boring" feature... there are much cooler ones available...

I had read that and, of course, became immediately curious. However, the development of our building area started around 2013/2014, and back then, that wasn’t the case yet, right?

That's correct, it came into effect at the beginning of 2016, if I remember correctly.

@Steffen80, of course I'm interested in KNX, but it’s too expensive for me and I probably won’t understand it.
My electrician might install a BUS cable from switch to switch. No idea what that would bring.

What kind of empty conduits do you have for the speaker cables?
For my main speakers, I use 2x2.5mm², which is more than enough.

I'm also interested in ceiling speakers, but I’m not sure if it’s possible in a concrete ceiling. I think that might be difficult.
That’s why I wanted to switch from Atmos to Auro 3D (so far it’s just been a theoretical plan for both).

I’d love to take a look at your installation, but you probably don’t live near me.

Not really much... but it’s better than nothing...

Data cables, etc., are installed in empty conduits (also called installation pipes) so they can be replaced if needed.

It’s all possible if planned in advance...

This was not planned in advance, meaning I would now have to drill into the ceiling. I wonder if the structural engineer needs to approve that.

I wanted to know what size he chose for the empty conduits. How do I actually get them from the ground floor to the upper floor when there is a ceiling in between? Just drill “a hundred” holes?

If this was not planned in advance, it is too late now... only assembly and similar work left, no more drilling into the ceiling.

For empty conduits, the larger the diameter, the better.

From the ground floor to the upper floor, yes, drill holes or use existing ones.
