Best retrofit smart home new build

Hello

Is there a good retrofit smart home?

We bought a semi-detached house as a new build from the developer.

The electrician dismissed the topic KNX and said he is not familiar with it and that we are not doing it.

My question is, are there good retrofit options for smart homes without having to tear open the walls (that is not an option)?

Which systems can you recommend to me?

Functions:

Light control
Window contacts (preferably not visible)
Shutter control
Music control
Video doorbell

It should definitely be possible to create scenes and rules.

I would also welcome further suggestions for good functions I may not have thought of yet.

Hi, we are also building with a property developer and had to forego KNX and other bus systems for cost reasons. I will mainly rely on Homematic, supplemented by Shellys and centrally controlled via iobroker. However, I made considerations about the desired functions in advance and had additional sockets and empty conduits installed accordingly. Let's see if it works out in the end...

is there a good retrofit smart home?

That is basically a contradiction in terms.

But if you want to bring everything under one roof then z-Z-Wave would currently be the best option.

If you look at the topics and the DIY sector then:

Light control – there is Hue

Window contacts (preferably not visible) – z-Z-Wave and Enocean

Roller shutter control – what should it be able to do? There are quite a few options from proprietary to....

Music control – what is meant by that? A few Bluetooth speakers or do you need a system that plays music depending on your mood and accompanies you through the house? Sonos is an option for the usual user.

Video doorbell – here comes the big budget question, because the good stuff is relatively expensive and also what should it be able to do?

gladly more suggestions for good functions I haven’t thought of yet

So far, I haven’t been able to discover any functions in the list. Scenes and rules yes, but that is a basic feature of all of them.

How much do you want to tinker (mainly) with software? That would be the first question... if you are good at that, you can put together quite a few of these toys reasonably well.

Are you an Apple user? If yes, OPUS GreenNet with the gateway. Runs very well and can also connect to some other systems. I just find the feel or the pressure point of the buttons poor, but that is similar with all buttons with Energy Harvesting (Zigbee, EnOcean, Z-Z-Wave, etc.). But that's also a matter of taste. OPUS covers many trades and is easy to configure.

Audio will be autonomous in 99% of cases, that only works with the app of the respective music device manufacturer or you put everything together, for example, with ioBroker. But then we are back at my first sentence – or at more expensive solutions that you can no longer install yourself.

Unfortunately, I am an Android user and actually want a system that does not limit me in my next phone choice. So it should be available for Android and IOS.

What should my next approach towards smart home be so that I can reach a result?

Forget about Apple, OPUS can also do Google Home anyway. So it would not matter.

Answer questions: 1. do you want to tinker yourself or have it done? 2. are you familiar with Linux basics? 3. what budget is available 4. what kind of "music" do you want to control 5. are you fixed or free in your choice of video intercom? Lighting, shading, and contacts can be managed by almost any system, even the magenta-colored one. It gets very exciting with music (what exactly?) and the door intercom.
