Bus system / home installation, looking for advice, cost plan

not to speak badly, but rather everyone should think beforehand about what is sensible and worth their money, and what is just an expensive gimmick.

Then the additional costs remain somewhat manageable.
Have a nice evening...

Personally, I have had the software for > a few years. First EIB experience was in ’92, then training on ETS1, license purchased.
Problem: You can hardly sell this stuff in the private sector. Public installations excluded, like hospitals, authorities, etc.
Some architects only look at the price and that’s where the fun unfortunately stops. The builder then decides on the budget version with relay switching, because KNX components + material + configuration/project planning + cables cost a lot of money.

Many clients often don’t want large technology at all – technophobia. One just wanted a 63A cam switch at the house entrance. All on – all off. Done.

Much has been written about cost/benefit. Personally, KNX/EIB never really convinced me and I stashed that stuff somewhere in the warehouse corner.

There are enough other bus providers on the open market. I currently have a colleague in Bulgaria who builds and programs finest Ethernet/wifi interfaces that can be controlled remotely from any PC. Also for Android there are tools where you can remotely water balcony plants in Croatia. Tablets in 10" format + Win7 + GUI offer enough interfaces for remote control in the house. When you compare what EIB/KNX specialist visualization displays cost?
In the heating sector, a well adjusted/parameterized heating system should run completely autonomously;
With EIB there is hardly any savings potential. Every remotely controlled relay card is noticeably cheaper?
Shutter controls are available from many providers. Central locking can also be managed with KNX.
Alarm systems via KNX? What is the current security standard? I once heard that various insurance companies do not accept KNX because it is manipulable.

I’ve also dealt with HomeMatic (elv). I find some solutions not bad.

Conventionally, I would route all lamp wiring to the floor distributor anyway. Whether the distributor is 2-row or directly 8-row… the price difference is no longer big. Copper is cheap anyway.
I would build push-button wiring on a DC basis? I built and engraved control panels myself. Often clearer than those KNX push-buttons (overpriced).

Siemens once said: This stuff will get cheaper anyway.
For a microchip produced in Taiwan for 10 cents and then sold expensively in an actuator, I find the device prices horrendous. Power supplies aside, because good power supplies always cost money.

Personally, I find it more sensible: Lay LAN Cat cables wherever possible; in hallways, children’s rooms, living rooms, kitchen. There you can then connect servers, cams, sensors, Ethernet LAN interfaces and control numerous consumers worldwide via the internet.

KNX/EIB has shot itself in the foot in the private sector. Mercedes is smarter there. They installed the CAN bus – no garage mechanic can mess around with that anymore.
They could have given the local electrician some extra income, but the industry was/is too greedy.

Personally, I threw EIB in the trash years ago. My conclusion: waste of time.
Today I prefer to ride my bike through the forest and sit in the beer garden.
Whoever wants to control their shutter control from the iPhone should install the KNX bus.

Good luck

What is the difference between KNX and EIB? .. do you have an electrical store kamnik? Do you need a different cable for that? I will lay a network in almost every room anyway. What convinces me about the bus system is that I have fewer switches and can also program the switches. Yes, the stuff is expensive ;( Regards Stefan

It used to be called EIB; currently, it should probably be called KNX. I haven’t dealt with it for a long time. That stuff was enough for me when at the trade fair the EIB or KNX equipment was made accessible for "home parametriers" without any ETS.
After that event, I just put all that stuff in a corner somewhere.

You pull the consumer supply lines into the floor distributors to the respective actuators.
For the sensors, you lay the modified telephone cable (YSTY 2x2x0.8 KNX) to the respective sensors (switches) as a ring, star, or combined layout? It’s a bus line.

An electrical store? – With a net profit of < 2.95%, no one opens an electrical store anymore today? For whom? For the tax office or for Greece?
You let others work and don’t work yourself anymore.

You do less programming there. It’s more like parameterization, isn’t it?

Anyone who wants to control their roller shutters from the iPhone should install the KNX bus.

Good luck

I read that we almost share the same opinion.
My statement about manageable costs did not necessarily refer to KNX.
