KNX is certainly not flexible. Just try laying a new bus cable in a freshly plastered house in a new location.
I do that from time to time, it’s no problem, especially in a freshly plastered house everything is still possible. But even if there is already paint or wallpaper, it’s not a big deal. Just because someone can’t imagine how something is done doesn’t mean it’s impossible. Besides, with KNX you plan ahead and lay the cable everywhere in advance.
Also here: if you don’t know how it works, you don’t have to claim it’s impossible and everything is inflexible. And renovations happen from time to time as well, then you can throw in even more cables if there is a demand.
KNX is much more flexible than it seems at first glance. Unfortunately, for many, the first glance is the end.
It’s certainly not easy either. Or why would I need the 1000€ professional software, which actually isn’t intended for end users?
Well, creating an Excel sheet with nested functions is more difficult. The professional software is rarely needed in a normal single-family house and 1000€ is also only the recommended retail price, nobody actually pays that.
Enocean is certainly older than KNX.
Ah, here again poorly researched half-truths and nonsense. When EnOcean was still a dream in the minds of Siemens engineers, KNX was already getting serious and the big players had merged into a alliance. By the way, thousands of installations have already been running across Europe for decades. Because KNX (=EIB) originated already in the mid-80s. Back then, it emerged from the Instagruppe which came from C-Bus, which is still used nowadays in Australia and New Zealand etc.
A small fact on the side: There are still installations from the very beginning and they are still running, and you can still find and buy the devices from back then today. You can then integrate these into a modern KNX installation (usually without the slightest problems with two or three mouse clicks).
Second fact on the side: One of my power supplies in the house I have had since 1999, and it has been more or less continuously in operation over the years, also in the new house. It was simply too good to throw away. It is functional, which is the rule with KNX devices and not the exception. This is one reason for the price, among others. Once bought, it works for decades and doesn’t need to be touched again.
And future-proofing still has to prove itself.
With EnOcean yes, the future will show whether it ever leaves its niche existence.
KNX has proven itself a long time ago and nowadays can only first play out its strengths. Because it is only through the possibilities we have today (smartphones, tablets, fast internet, IoT etc.) that you can actually exploit and experience the potential of a connected house. In the 90s and 2000s KNX was far ahead of its time.
