Hello everyone,
I am currently planning the components for my smart home in a new build.
Thanks in advance
I am currently planning the components for my smart home in a new build.
- The electrical installation will be done conventionally.
- Roller shutters controlled only via smart home, without physical switches. Seasonally controlled (Sonoff relays).
- I also want to control underfloor heating circuits solely via smart home. For this, I would need temperature and humidity sensors in the rooms. Which ones would you recommend? Which relays could I use for the valves? They are just on or off. I would probably need about 8 to 10 units.
- I want to override light switches in the rooms using Shelly devices.
- There will be touchscreens on two floors displaying all information and control options.
- Additionally, Android apps on every phone for home control.
- In the living room, a configurable button with a display? What would be suitable here?
- Alarm system with motion sensors and possibly door contacts.
- Control via OpenHAB.
- Which sensor can I use to control any actuator with a simple wall switch?
Thanks in advance

Where could I find a brief, clear, and reliable source to understand this? Pages 46 to 65 of Stefan Heinle's book "Home Automation with KNX, DALI, 1-Wire and Co."

With the electrician?? How can I tell if he is among the 10% who are knowledgeable? I belong to the 90% 😀 Recommendations, forums, groups. Definitely not websites and industry directories.
Otherwise, I would like to 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 necessarily "unnecessary." For example, does Alessandro drive his car with a portable radio on the passenger seat, a fan heater in the footwell, paper maps on the dashboard, a cordless phone in the air vent, and a consumption indicator in the form of a sight glass, while still manually rolling his windows up and down? I don’t think so.

Just because some people can’t imagine certain things doesn’t mean they’re unnecessary. For example, does Alessandro drive his car with a cassette radio on the passenger seat, a fan heater at his feet, maps on the dashboard, a mobile phone in the air vent, and a consumption gauge in the form of a sight glass – all while rolling his windows up and down by hand? I don’t think so. Well... we know he probably doesn’t do that, so extreme comparisons usually don’t hold up. It’s his point of view, and apparently he’s fine with it, which is what matters. But I do also understand the opposite perspective. I like reading about topics I would never have been interested in before because I want to understand why people think that way and see if something might be interesting for me; so I’m always open to new things but equally critical.
For some of the “must-haves” I often see discussed here, I know they don’t fit MY way of life or priorities, and I consider many things just passing trends.
Regarding KNX/automation, it’s probably different. Still, so far it’s hard for me to find the key point because I sense from many posts that people do it just because it’s what you do, as nowadays men prefer sitting in front of a server cabinet programming functions rather than sitting around a campfire or mixing concrete like in the past... how unmanly 🤨
Sometimes I wonder when I read that someone wants their house definitely with KfW-standard XY and KNX, etc., but I don’t see or read anything about a pleasing living style, thoughtful color design, comfortable, high-quality furniture, and so on.
By the way, thanks for the reading recommendation; I’ll keep reading and see what I like or don’t like about it.

It’s not a lack of imagination, but so far my personal comfort gain compared to the costs incurred, the effort of searching and researching, and the risk of ending up with the wrong person is what’s stopping me, as has happened here even with people from the industry.

Oraclefile20 Nov 2020 20:51How would you implement a wireless lighting system that adjusts the color temperature and possibly the brightness of the lamps according to the time of day? Unfortunately, I haven't been able to find a solution anywhere. It mainly concerns ceiling spotlights, but also other lamps. The Ikea Tradfri system sounds attractive because it can be integrated directly into the spotlights and is affordable, but it only works with its remote control. Additionally, Yeelight lamps are already in use, which ideally should also automatically adjust their color temperature.

This might clarify how the pricing structure of KNX devices is built up and why these devices are never exactly cheap.
In my case, the motor is not a "dumb" one with just four wires that can only move up and down and maybe save end positions automatically. Instead, it has a full microprocessor control integrated, which has about the same level of intelligence as the control system of a heat pump. That means dozens of parameters are continuously monitored and output just for this motor. You just have to feed it with sensor data from other sources like, for example, a power meter, window contacts, or also temperature and solar intensity. Then you configure the desired functionality, set delays, locks, and alarms, and that’s basically it. Usually, manufacturers are not stupid and provide many helpful tools out of the box, which can be used in the motor’s user interface. For example, scenes, learning functions, or in the case of a tubular motor, a complete shading control.
For those who don’t understand the heat pump control comparison: you could also say every KNX device basically has a Raspberry Pi integrated, on which you just click together the necessary functions. So in my case, there would be a Raspberry Pi at every window, which constantly communicates with the others and knows exactly what is going on in the house.
No, no, no… completely wrong again. You don’t sit there daily, weekly, or monthly; that would drive you crazy if the automation caused more problems than it solves. Although, admittedly, there are quite a few systems behaving like that, constantly glitching and bugging. KNX is not one of them. The philosophy here is: set it up once and forget about it.
Of course, it takes a few days at the start during initial commissioning, since you can’t exactly predict 100% how you want everything to run beforehand.
And yes, if you change something or add something new, you have to brief yourself. But then not in front of the server cabinet—instead comfortably from the sofa while browsing the internet.
I think I only needed to touch it twice this year. Once to add a new device and once to adjust a few settings. Each time not longer than 10 minutes on the laptop.
Most of what you mentioned is usually already in place when using KNX because it still has the reputation of being expensive and unnecessary. The best example is Rick. Nevertheless, KNX has now become accessible to everyone since the costs are slowly but surely trending downward.
A major plus of KNX, besides the limitless variety and uncompromising interoperability, is the design of the touch sensors. These can even be customized in color or material to match high-quality furniture, tiles, and so on. Because it’s not only white plastic or colorful plastic. There are also many metal variants, wood, and other materials. So it’s not a plain light switch, especially not a row of three, four, or five stacked switches, but rather stylish and discreet. Yet always multifunctional.
The risk exists with chimney builders or pavers as well. They can have dozens of reviews and many orders. In the end, you might just end up with their Monday project.

Osram Lightify could do it, but they’re now discontinued.
You can get Innr lamps with tunable white and then connect them to, for example, Philips Hue.
