Lighting and electrical planning in new construction

Psssst, I already patted myself on the shoulder :D

This thread is great. I had actually already thought that I neither need Smart Home nor KNX. Now I am sure. Never ever. A simple (light) switch always works, needs no software update and no control devices. How many hundreds of computer connection plugs and interfaces have been developed in the last 25 years? And every time people thought this was the perfect system. Until another one came. And 5 years later there is nothing left that you can connect to it.

That actually says everything about your post :rolleyes:

Thanks for the hint! That already helps a lot! But 60K is of course a whole different ballgame

60K € is a lot of money. You have read my list of what we implemented for this money. Keep in mind that quite a bit of it has nothing to do with KNX. Our architect at the time also estimated 20K € for a classic electrical installation. However, since she (we honor her, seriously) has no clue about modern electrical systems, I claim that was very optimistic. With those 20K € we would never have been able to implement our current network installation, the audio/video door station, the camera surveillance. She also didn’t consider any "frills" like central lighting and roller/shutter/blind control or motion detectors for the outdoor area. If you want to consider all that, 20K € is completely unrealistic. Thus, I cannot say we paid 60K € for KNX. Rather, we paid 60K € for an upscale electrical setup including KNX.

KNX is the same. Always works and doesn't need updates. You probably confuse it with the pseudo-smart systems from online retailers.

How many hundreds of computer connectors and interfaces have been developed in the last 25 years?

Yep, many, for various reasons. KNX has stuck with the KNX terminal, USB, and RJ-45 connector for these 25 years, and nostalgics can still address it via RS-232.

And every time people thought this was the perfect system now.

No, nobody ever thought that. At least no one who is (even slightly) more than just a user. It has always been clear that the interfaces will keep changing. Alone for reasons of resource conservation.
