Hello everyone,
some of you might know that I’m new here and slowly getting familiar with the relevant topics. As a very tech-savvy person, I am particularly interested in automation.
I’m surprised that the current trend in advice for new builds leans towards connecting everything via bus cables. This involves a huge amount of planning with a very high likelihood of retrofitting over the next 30 years. A wireless solution or a powerline communication system would technically be completely feasible, requires much less planning, and involves hardly any extra work for the electrician. Every component to be controlled is powered anyway. Therefore, each component could be addressed via the regular power cable. And if someone wants to save a bit during construction, they could simply upgrade certain components like lighting later on and operate them manually until then. There are no additional costs for a non-smart installation of a light fixture.
Or is this already the case, and I have misunderstood the recommendations for implementing bus systems like KNX and others?
Best regards,
Matthias

You’re "dead" faster than you can blink because you see your opponent 30ms later than they see you.

At our company, there was once the idea to install a few access points per floor so that all laptops would use Wi-Fi exclusively. After six months, everyone had their LAN cable back at their docking station, and Wi-Fi was only used when moving around the building.
In my opinion, all stationary devices should be connected via LAN, and only mobile devices should use Wi-Fi, which is what Wi-Fi was originally designed for. Nowadays, people want fast and stable Wi-Fi, but this is not achievable. Speed comes at the cost of stability, and stability comes at the cost of speed!
Wi-Fi can never replace LAN; it can only complement it.

By Powerline, I simply meant using the electrical wiring (no matter for what purpose).Yes, we understand you. However, it is very suitable for transmitting high voltages; for data, it is only suitable for isolated solutions and not for complete building automation.AleXSR700 schrieb:
Personally, I try to avoid LAN as much as possible.Why is that? A general dislike of cables?AleXSR700 schrieb:
But okay, technically they obviously haven’t succeeded in using the electrical network cleanly. A star topology is the "cleanest" in terms of speed and peer-to-peer communication but also the most complex to implement in hardware.Well, basically yes, but it’s not necessary. It has more disadvantages than advantages.AleXSR700 schrieb:
I don’t mean that every meter of cable is expensive. But, for example, if you want to retrofit the attic later, you have to pull cables through the entire building to supply the attic.Where do you see a problem with that? I don’t see any.AleXSR700 schrieb:
With a powerline network, that wouldn’t have been necessary.Yes, it would. Even with existing power cables on the roof, you still need to pull additional cables if you want to supply more than just a few lights.AleXSR700 schrieb:
And with wireless, not either.Yes, absolutely even with wireless. You still need an infrastructure. For the attic, you’d need additional mounting panels, etc., which are generally more expensive to install and operate than a cable at 36 cents per meter.AleXSR700 schrieb:
Okay, so ideally you should plan lots of cable routes very early and know exactly where each device will go—and where each piece of furniture will be. Then maybe even install an empty conduit in every room just to be safe? The planning sounds really complex.Building a house should never be taken lightly anyway. I don’t understand why electrical work is still treated as an afterthought. Most homeowners usually spend far more time carefully planning tile selection or the kitchen layout.Mycraft schrieb:
Building a house should never be taken lightly. I find it incomprehensible why the electrical trade is still often neglected. Most homeowners usually give much more thorough attention to choosing tiles or planning a kitchen.
Above all, people almost always start thinking about this topic too late.
On top of that. For this reason, modern houses often have the mandatory fireplace and three power outlets. But outside the door, there is an electric car filled with sensors.
Interesting fact: Even in cars, buses are used instead of wireless communication. Only the essentials are operated wirelessly, such as the car key (and its variants), hands-free systems, radio, and mobile internet access.

[...] Wi-Fi can never replace LAN, only complement it.Exactly. Cables and stationary users belong together – this association works both ways! Wireless makes sense wherever devices or users are mobile or nomadic, but a roller shutter motor is always fixed in the same unit. “Wireless cables” are the most expensive option in every respect: complex to plan, difficult to control for quality – basically only popular with admins who struggle to use punch-down tools.https://www.instagram.com/11antgmxde/
