Hello
Are there good retrofit smart home systems available?
We bought a semi-detached house as a new build from a developer.
The electrician declined to work with KNX and said he is not familiar with it and won’t do it.
My question is: Are there good retrofit options for smart home systems that don’t require opening up the walls (that is not an option)?
Which systems would you recommend?
Functions:
Light control
Window sensors (preferably invisible)
Shutter control
Music control
Video doorbell
It should definitely be possible to create scenes and rules.
I’m also open to other suggestions for useful functions I may not have thought of yet.

As mentioned in a few posts earlier, just run a 5-core cable to every room, and you’ll have all the options later to make individual sockets switchable. In rooms where I already have exactly two use cases for switchable sockets, either a 7-core cable was installed or a second 5-core supply was added.
There are also many system integrators active in the KUF. Of course, they don’t like it when a self-made homeowner thinks they can handle it just as well on their own.

It hardly gets simpler, cheaper, or more flexible than a ring circuit made of 5x1.5 mm² (AWG 15) per room. Then, flush-mounted actuators are not necessarily required. You simply wire it in the distribution board as needed, and if your requirements change 10 years later or even just after 3 months, you can rewire it (or have it rewired) exactly as you need.
All without dust or noise.

The only one I know with power measurement is the RF-AZK1ST.01.
I don’t think it’s bad, but it’s not exactly very elegant either. ;-)
5NYM for sockets is not exactly a miracle solution either. It just offers one permanent, one measurable, and one switchable line...
@AllThumbs: Did you really implement it that way, or is that just the idealistic view? It worked for me in children’s and guest rooms, but bathrooms, kitchens, living rooms, heat pumps, technical rooms, outdoor areas, ... quickly became very complicated. Sometimes one neutral conductor is no longer enough, and detailed discussion and planning are necessary.

You can switch or measure up to two (groups of) sockets per room flexibly. I especially like this when I don’t yet know exactly how or where I will use the sockets.

I especially like that if you don’t yet know exactly where or how you’ll use the outlets. Better than nothing, true, but my wife wants the reveal outlet to be switchable, I want the TV to be measurable for scenes, and then nothing is left over.
And of course, this only works if the lighting is already wired individually, plus you have to convince the electrician to run 5NYM cable past every outlet. Mine runs single wires and sometimes connects the ends directly at the switchable outlet, which makes rewiring impossible.
