ᐅ Prepare new construction for future wireless smart home integration

Hello,

I spoke with the electrician for our new build, and he wants to install KNX. Because of that, I want to prepare my house for a wireless smart home system.

At the moment, our budget is tight due to the new build, and we want to focus more on having a nice bathroom.

Since the new smart home standard Matter will be introduced this year, which I believe will become the leading solution for retrofit installations, I want to prepare our new build for a later Matter retrofit.

I know that these retrofit wireless solutions are not the optimum (KNX remains the absolute top), but unfortunately, you don’t always have the budget for the best system.

I think Matter will establish itself, but if it doesn’t, I want to be able to install another system later, for example Homematic IP, Zigbee, Z-Wave, or EnOcean.

What should I tell the electrician to ensure that one of these retrofit smart home systems can be installed later, preferably Matter with Thread?

What does the electrician need to do differently compared to conventional electrical work or installations?

Or does the electrician not need to do anything differently, and I can just replace light switches, heating controls, etc., later and simply attach window sensors to the windows?

Sorry, I have very little knowledge about electrical work.

However, I know someone who can later replace the light switches and such (although he has zero knowledge about smart homes and would just connect everything according to instructions).

So, can the normal electrical wiring be installed first and then I replace the switches afterwards?

There are several options. You can either replace the switch or install an additional device behind the switch. The cost is about the same for both. So if you are happy with the look of your current switch design, you will just need a small device behind it. The larger the electrical box, the easier it will be to handle later on. You can look up the difference by searching for “Kaiser deep box” and “Kaiser electronics box.”

What is important to me:
Roller shutter controls with window sensors
Heating with window sensors
Lighting
a few power outlets
and a video doorbell

All of that is straightforward except maybe the video doorbell. I would research that in advance and probably install it during the initial wiring. In theory, there are battery or rechargeable solutions, but if possible, I would avoid them. Therefore, the right cable needs to be installed there.

Why battery replacement? If the light switch or roller shutter switch has power, then they don’t need batteries, but for window sensors, of course, you need to replace the batteries.

Yes, I mean the window sensors. The others can work without batteries—as long as the switches are installed in the proper locations.

What are electronics boxes?

See above.

Make sure to install deep flush-mounted boxes everywhere.

What do I need for the video doorbell?

The doorbell should definitely be wired and not battery-powered.

Deep mounting boxes should always be installed, regardless of whether you want automation or not. It simply makes things easier for the electrician later on and allows for faster and simpler modifications if needed.

What you need for the video doorbell depends on the system itself. However, I would recommend providing LAN and telecommunications cables, for example A-2Y(L)2Y 4x2x0.8.
