ᐅ Bus system / Home installation, seeking advice and cost planning

I will do it on my own as well and only install what truly makes sense. For example, it doesn’t make sense to control your oven remotely.

For example, it doesn’t make much sense to control your oven remotely.

Yes, there are many more or less ridiculous examples from manufacturers trying to make the topic appealing...

In the morning, when I press the switch in the kitchen, the light turns on, the coffee machine starts, and the internet radio begins playing my favorite station throughout the house. The blinds go up, and the towel warmer in the bathroom switches to maximum...

But if I just want to turn on the light or skip the radio, it already gets complicated...

The same goes for motion sensors controlling lighting in the stairwell... It can be done, but you will probably get annoyed more often than you expect, especially if you have pets... and you probably won’t save energy either when you consider the power consumption of the involved bus components...

Useful things include automatic shading... retracting external blinds during strong winds... automated control of heating and mechanical ventilation with heat recovery, detection of open windows... an "all off" switch at the door...

Many things are just expensive gimmicks that consume electricity and can break down...

Here is my two cents on the subject:

Personally, I’m not a fan of EIB systems because I don’t see their benefits.
“Simple” expandability always involves programming (which costs significantly more per hour compared to a regular electrician’s rate).
For a new power outlet or switch, you still need the supply line plus the bus cable, which means higher costs.

Just search for "Siemens Logo"—it offers at least the same functionality at a much lower cost.
However, it should be installed centrally (for example, in the distribution board).
The wiring has to be adjusted accordingly, but you don’t need bus cables for this.

Wow... I programmed PLC controllers in my studies until I was completely fed up. You really don’t want to hear my pain—uh, hourly rate.

Hehe, a logo is basically just a small PLC.
However, I find the functions more than sufficient for controlling roller shutters, lighting, etc.

If you combine that with a nice touch panel or two, it’s really a great setup. (just my taste!)
And above all, a switch doesn’t then cost 100 €.

---> Decentralized <--- that is the main advantage of EIP compared to a PLC solution.

“Simple” expandability here always involves programming. (which costs significantly more per hour than a regular electrician’s labor.)

Programming it yourself? You have to do that with a PLC as well...

Just Google “Siemens Logo” — it provides at least the same functions for much less cost. It is just supposed to be installed centrally (e.g., in the distribution board). The wiring needs to be adapted, but no bus cables are required.

My main concern with such solutions: if the PLC fails, nothing works! No lights, no shutters, etc. How long does a PLC last under continuous use? It might last 10 years... it might fail after 5... or after 15... will you still get compatible replacements then?

If an EIP participant fails, all the others continue to work without errors...
