ᐅ Consultation for Smart Home New Construction Wireless Systems

I always find it unfortunate when electricians stuck in the past with an "old school" mindset limit the options available to clients. However, this is still far better than the many electricians who see dollar signs instead of questions in their minds. Projects like these often contribute to KNX’s "bad reputation," making it seem like it offers little added value in private homes, hardly works properly, and is very expensive because someone else has to fix the work of the inexperienced electrician at a high cost.

Everyone has different priorities. Personally, building automation along with IT infrastructure ranks much higher on my list than, for example, the front yard. Both are perfectly legitimate.

It always depends on what you want and whether you can find someone who will implement it at a price you find acceptable.

I’m by no means a smart home expert; it’s more about partial “ease of use.” Still, I want what is done to be properly executed. For example, having the roller shutter motors wired in a star topology so that I can install the control centrally from the distribution board. Unfortunately, the star wiring costs me an extra €55 per roller shutter/blind, but it’s done properly and not a makeshift flush-mounted solution. That way, I can consider using DIN rail actuators or even connecting a LOGO! 8 later on.

Absolutely right. Nowadays, rigid and inflexible wiring from grandfather’s times should be avoided in favor of structured cabling. This way, you have full flexibility and can easily adapt the cables inside the walls later if something changes, if something was forgotten, or if something new is developed—without having to tear open the walls.

You might also want to take a look at Digitalstrom. It doesn’t require any additional wiring and can be retrofitted or expanded at any time.

Basically, I have never really understood the cost/benefit ratio of a smart system in a standard single-family home. 90% install underfloor heating, so heating control systems are usually unnecessary. Shading solutions with integration of wind, rain, and sunlight sensors are available from many manufacturers using wireless technology. The same applies to lighting.
If desired, you can even implement constant light regulation through this, but who really wants that in a single-family house?
Otherwise, I can’t think of anything else I would want or could smartly automate in the house...

A constant light control system is not particularly impressive and is generally not necessary in a single-family home; it is mainly designed for office environments.

In contrast, Human Centric Lighting (HCL) is very relevant in single-family homes and is becoming increasingly popular.

Individual systems usually perform their tasks well, such as the heating control or shading solution you mentioned. However, if you want to coordinate these systems and benefit from their integration, it becomes difficult without a common platform, and you end up with something like an iron in the refrigerator.

That's true, but for me, the cost-to-benefit ratio is not justified.
