Make our new building smart

Never attack the KNX disciples... They defend their system to the death!

Unfortunately, neither "side" has presented any compelling reasons.

Now I am also being falsely accused of things. I never said that laying a cable is an insurmountable obstacle. It would be nice if we could stick to the facts. What I said is that it is not particularly flexible if you first have to break open the wall. It is doable or affordable but not flexible.

I have no deficits. But thanks for seeming concerned. I know how things work. And planning 99% in advance is KNX, but as I said, that is not flexible.

Just compare the prices of the KNX components when KNX is comparably expensive. Until then, the statement is just propaganda.

And then you are the one who believes in the horse because the car is just a temporary phenomenon.

The thing with cars, okay. But the internet won’t work... Don’t worry, I think Enocean itself is great. The battery-less concept is, in my opinion, the most well-thought-out among wireless systems. And since it is a real standard, it is clearly superior to a proprietary system like e.g. Loxone, even though that is a completely different mechanism again. What I don’t like, however, are direct comparisons like you make here with EnOcean vs. KNX. That’s still far from comparing apples and oranges. EnOcean is absolutely great for retrofitting or if you roughly messed up during planning. But not in new construction when you have everything under control from the start. These are simply empirical values from many years in this industry. Always cable over wireless, anyone with at least a modicum of knowledge will confirm that to you. If only wireless works, very gladly. Jäger has established a great EnOcean program with OPUS GreenNet with a really good product range. I currently have that in a project, but only because it can’t be done any other way. Those are just my 2 cents on it.

People... settle this privately! So childish by now

The components of Opus Greennet are, I believe, rebranded eltako components. The product range of Eltako is also much more extensive.

Instead of decentralized UP installation, I would opt for a central installation in new buildings. Actuators on DIN rails in the fuse box and technical room.

Flush-mounted actuators are more of a retrofit solution.

Push buttons and sensors can also be connected via bus cables, but the system can be expanded at any time with radio modules and remains flexible. The advantage of radio is that you can do it yourself and save on the technician.
Visualization and programming are cheap and versatile, e.g. Openhabian (Openhab) on a Raspberry PI. IOBroker, FHEM, NodeRed, etc. also lead to the goal. Apps for tablet or smartphone can also be easily created this way.
Compared to KNX, this is cheaper. You can see it negatively that you have to do something yourself, or positively that you can do something yourself.

Neither of them manufactures it. They all just buy from 2-3 actual manufacturers and have their name printed on it. The joke with OPUS is that the gateway is the only EnOcean gateway certified for HomeKit so far. But even that is not built in-house; it comes from Stuttgart.
