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:

Thank you very much for your help.

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.
- 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 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?
Thank you very much for your help.
Most of the information about the network is already mentioned above.
KNX and lights / blinds / heating control: It’s a nice feature, but for a standard house it’s purely a gimmick. To me, KNX is not an investment in the future-proofing of your home. The resale value will hardly decrease without KNX, nor do I expect future generations to necessarily require it.

A gimmick, nice to have if there is extra money, but not a future-proof investment with returns. Without returns, yes, approved.

From my perspective, your questions about the wiring are quite basic, so I assume you haven’t dealt with the topic in depth yet. I would recommend having an electrician plan it for you, and possibly taking on only certain tasks yourself, such as laying the cables. Installing the cables into the outlets and patch panels is not easy for a beginner and, if done incorrectly, can lead to connection problems later on.
Overall, though, I think it’s good that you’re gathering information here so that you know exactly what you want when talking to the electrician.

Devices from the very first generation still operate perfectly fine alongside the latest ones fresh out of the factory... KNX does not have generations—that’s actually one of its biggest advantages.
Everything is backward compatible, and the basic principle hasn’t changed for decades... only new devices with more functions have been developed... but as I said, the old ones still perform their job perfectly well... Building technology can’t be compared to smartphones or TVs.

The company GIRA is great, but also very expensiveDo you have any other recommendations that are similarly good but more affordable than GIRA?

Whether duplex cable or two separate cables doesn’t really matter... for example, I simply installed two cables everywhere because it was easier and cheaper...Okay, so as an alternative to duplex cables, pull two or more single cables each time. Are 25mm (1 inch) conduits sufficient?
Mycraft schrieb:
From each outlet, the cables must run to your central point—meaning the basement/utility room—where the cables (since they are installation cables) are then connected to a patch panelRegarding the patch panel: I understand why a patch panel is used. But how and where exactly is the patch panel module mounted?

For example, I have 4 satellite receivers connected to 8 tuners... so there are 17 cables from the dish to the multiswitchDo you have 17 cables running from your satellite dish into the house? Or do you actually have 4 satellite dishes?
Mycraft schrieb:
KNX is a great system... I have installed it myself... the possibilities are endlessHow could one pre-wire for KNX if planning to install it later? For example, is it useful to already lay the cables now?
Thanks a lot to everyone in advance. This forum is really great, with very friendly, clear, and detailed explanations!

Basically, I think it’s good that you’re educating yourself here so that you know exactly what you want when talking to the electrician.Hello Jochen,
You are 100% right. My questions are basic. My intention is to do things like pulling cables myself. The actual connection work has to be done by an electrician. It is important for me to understand what I’m doing, why I’m doing it, and to avoid being taken advantage of by an electrician.
When I don’t understand something, I ask questions until I do. Sorry if some of my questions seem too simple to some. But I think you all explain things really well. Thank you very much for that.
PS: I still have time to carefully familiarize myself with the subject.
