where could I read something briefly, concisely and seriously informative to grasp this

Pages 46 to 65 of Stefan Heinle's book "Home Automation with KNX, DALI, 1-Wire and Co."

With the electrician?? How do I recognize if he belongs to the 10% who are knowledgeable? I belong to the 90% :D

Recommendations, forums, groups. Definitely not websites and business directories. Otherwise, I can add one of my favorite quotes to this discussion: "I think there is a world market for maybe five computers". Thomas Watson, Chairman of IBM, 1943. Just because some people can't imagine certain things doesn't mean they are "unnecessary." Or does, for example, Alessandro drive his car around the world with a suitcase radio on the passenger seat, a fan heater in the footwell, maps on the dashboard, a radio phone at the ventilation slot and a consumption indicator in the form of a sight glass and still manually roll his windows up and down? I don't think so.

The car is a great example, I also often explain it that way. Because the other person suddenly understands what is being talked about. The car is well known and you can then imagine everything.

I lack the understanding of how it is detected with PM and two sensors that the roller shutter is not allowed to go down. Therefore, the question is how this is implemented.

Just because some people cannot imagine certain things doesn’t mean they are automatically "unnecessary." Or does, for example, Alessandro drive his car with a portable radio on the passenger seat, a fan heater in the footwell, maps on the dashboard, a radio phone in the air vent, and a consumption gauge in the form of a sight glass while manually rolling his windows up and down? I don’t think so.

Well..... we know that he probably doesn’t do that, so extreme comparisons mostly fall short. It’s his point of view and he apparently manages with it, and that alone is what counts. But I also equally understand the other perspective. I also like to read about topics that never interested me before because I want to understand why people think this way and to see if something might be interesting for me; therefore, I am always absolutely open to new things but at the same time critical. With some must-haves that I often read about here, I know that they are not an option for MY life regarding what is being discussed, or I set completely different priorities in living and see much as a passing trend. With this topic KNX/automation it is certainly different, yet so far I find it hard to extract an essence for myself because from many posts I believe you can see that people do it simply because they do it and because nowadays men prefer to sit in front of the server cabinet programming some functions instead of sitting around a campfire or stirring the concrete mixer as in the past... how unmanly o_O I just sometimes wonder when I read that someone is planning their house and it definitely has to include Kfw-xy and KNX etc., but I don’t read or see anything about beautiful living style, thoughtful color design, comfortable, high-quality furniture, and so on. By the way, thanks for the hint about reading material, I will continue reading and see what I like or don’t like about it.

But hardly ever in such a way that I can find someone locally who offers it competently and reliably like a chimney builder or paver; so I either throw myself into it endlessly myself or risk accidentally hiring an amateur. It is not due to a lack of imagination on my part, but so far rather due to my PERSONAL comfort gain measured against the costs incurred, the effort for searching and researching as well as the risk of getting the wrong person, as was the case here even with people from the industry.

How would you implement lighting on a radio basis that adjusts the warmth of the light and possibly the brightness of the lamps according to the time of day? Unfortunately, I couldn't find a solution anywhere. It is mainly about ceiling spots, but also other lamps. The Ikea Tradfri sounded attractive regarding direct integration into the spots and being inexpensive, but they only work with this remote control. Furthermore, Yeelight lamps are already present that should preferably also automatically adjust the temperature.

Maybe this makes it a bit clearer how the price structure of KNX devices is built up and why the devices are never exactly cheap.

The motor in my case is not a "dumb" one with 4 cables attached, which can barely just move up and down and possibly automatically store the end positions. Instead, it has a fully-fledged microprocessor control integrated, which has roughly the same intelligence as the control of a heat pump. In other words, dozens of parameters are continuously monitored and output just on this motor. You just have to feed it with sensor data from other sources, like e.g. a PM, window contacts, or also temperature and solar intensity. Then you click together the desired functionality, set e.g. delays, locks, and alarms, and that’s basically it. Usually, manufacturers are not stupid either and offer many helpful tools out of the box which can then be used in the motor’s user interface. For example, scenes, learning functions, or in the case of a tubular motor even a complete shading control.

For those who can't deal with the heat pump control as a comparison: You could also say every KNX device basically has a Raspberry Pi integrated on which you just click together its required functions. So in my case, there would be a RaspBi at every window which then constantly communicates with the others and exactly knows what's going on in the house.

With this KNX/automation topic it’s certainly different, yet so far I find it hard to extract a gist for myself, because in many posts I seem to recognize that one just does it because one does it, and because today’s man instead of sitting around a campfire or stirring the concrete mixer, prefers to sit in front of the server cabinet and program some functions... how unmanly o_O

No, no, no... completely wrong again. You don’t sit there daily/weekly/monthly, that would drive you crazy if the automation causes more problems than it solves. Although admittedly there are quite a few systems that behave exactly like that and something is always stuck or buggy. KNX is not one of them. The philosophy here is: set it once and forget it.

Of course, it takes a couple of days at the beginning during commissioning, because you can’t estimate everything exactly and 100% beforehand. How what should run and is desired.

And yes, of course, if you change something or add something new, you have to tweak briefly. But not in front of the server cabinet but comfortably from the sofa. While browsing the internet, for example.

I think I only had to do it twice this year. Once installed a new device in the system and once adjusted a few settings. Each time no longer than 10 minutes on the laptop.

I just sometimes wonder when I read that someone is planning their house and it definitely should have Kfw-xy and KNX etc., but I don’t read or see anything about beautiful living style, thoughtful color design, comfortable, high-quality furniture etc.

Most of the time what you listed is already given with KNX because it still has the reputation of being expensive, unnecessary, etc. The best example is Rick. Nevertheless, KNX is now available for everyone as costs are slowly but surely trending downwards.

A big plus of KNX besides the endless variety and uncompromising interoperability is the design of the touch sensors. And these can even be adapted color-wise or material-wise to the mentioned high-quality furniture/tiles etc. Because it's not just plastic in white or colored plastic. But many metal variants, wood, and other materials as well. So it’s not just a plain light switch and definitely not 3/4/5 one under the other but chic and discreet. But always multifunctional.

But hardly ever someone on site offers it competently and reliably, like a chimney builder or paver; so I throw myself in endlessly or risk accidentally hiring an amateur.

The risk is the same with chimney builders or pavers. They can have as many reviews and orders as they want. In the end, you might just catch their Monday project.


Osram Lightify could do it but they are now dead.

Innr lamps can be bought with tunable white and then for example connected to Philips Hue.
