Hello,

we are currently building a semi-detached house with a developer.
Our assigned electrician does not offer smart home (he only wants to do the standard electrical installation) (that's just how it is with developers).

However, we would like to have a simple "smart home" (I know smart home is the wrong term) or retrofit it later.
Our new building is supposed to be handed over before March 2023.

What options do we have for retrofitting a smart home?

What do you think of the new smart home standard Matter?
I can already imagine that Matter can replace the current wireless smart home protocols (Zigbee and Z-Wave).
As an alternative to Matter, I could imagine Enocean.
What do you think of EnOcean? I like the idea of it being batteryless.

Which smart home wireless standard would you say is future-proof and could recommend to me?

I do not have to set up the smart home immediately after handing over the house; I can also do it after about a year (in case Matter is delayed).

We actually only want to cover the standard functions:

Light switches
Sockets
Roller shutter control (we have electric roller shutters everywhere)
Window contacts (preferably invisible in the handle with handle position detection)
Underfloor heating controller
Weather station
Video doorbell (to retrofit ourselves)
possibly also a door lock (e.g., Nuki)

All of this should then also work together with smaller simple automations.

You would advise against Homematic IP because only one manufacturer is behind the technology, right?

To be able to retrofit later, what do we need to have prepared by the electrician during the new build?
Since these are retrofit systems, not much, right?

I think we should have the electrician prepare the following:

- Deep flush-mounted boxes to be able to retrofit the smart home technology?
- only simple light switches installed (I have never seen these toggle switches on smart light switches where you can switch a light on and off from right and left)
- sufficient LAN cabling

What else do we need to consider?

Thank you very much for your help so that we don’t make mistakes.

A wired smart home like e.g. KNX is unfortunately not offered by the electrician (it would probably be too much and too expensive for us anyway). We do not have the biggest smart home demands; we just want to increase our comfort a bit, and of course, it is a bit of a toy.

There you can already find a thread about Matter.

If you want to use "only" wireless anyway, it basically doesn't matter what you use. I have already used Homematic. It works.
Soon I will install a few Shellys and run everything via ioBroker.

Note: You can save the money for automating the heating. If the heating is properly set, it will run. Then you can also remove all switches and actuators.

We are building without heating in the basement. The entire development area is to be supplied with local heating from a combined heat and power plant.

According to the developer, we will get ERR that also respond to the temperature.

Unfortunately, we cannot do this via the heating.

Do we need to consider anything else besides the light switch (is that even correct?) and the deep installation boxes?

Deep boxes are probably important first of all. These are standard in our construction specification. Then the question is how much you want to combine all this under one roof? I have now decided to simply use different apps. Smart Home may be something else, but I will first implement the following:

- Bosch roller shutter actuators
- Bosch Smart Home smoke detectors Twinguard
- Bosch motion detectors with integrated alarm system
- Doorbell, cameras, and vacuum robot come from Eufy
- Philips Hue for lighting

Then everything is connected with Alexa and that’s it. Costs are very manageable and I have my playground :cool:

I would like to have everything in one APP (or as few as possible), which is why I find Matter so interesting, for example, where everything from all manufacturers is compatible with each other and then everything is combined in one APP

and then everything connected with Alexa or Google (with Matter you can also choose and switch anytime)

But similar to you , we want to do it that way too

What do you think about Enocean? for example Eltako or Opus

Engine displacement cannot be replaced by anything. In this sense, I only know one effective remedy when an electrician is incompetent and/or unwilling, and that is armies of empty conduits* (note especially: only an empty empty conduit is an empty conduit!). Since I am not in favor of unnecessarily generating my own electromagnetic pollution, I see wireless connections exclusively for nomadically used end devices - what is used in a fixed location should be offered wired connection options.
The most important thing about "standards" is not how "new" they are, but how "compatible" they are, because for the latest craze in electronics season 2022/23 you may hardly be able to get the necessary legacy drivers even second-hand by 2035. Also note a trivial insight here: traffic routes reserved for star/tree network topologies* can be more easily converted to a bus topology than vice versa. Standards and quasi-standards are not only difficult for beginners to weigh against each other, an important criterion is their spread: better to have a large consortium of manufacturers and co-developers behind it than just a single one (even if it has a very impressive market share). You fundamentally have to ask yourself what type you are: do you place more value on the hippest and fattest feature set and are willing to pull all cables again after eight years (when it is "unfollowed" by all the hype starters), or do you understand "smart home" and "retrofitting" rather as immediately retrofitting only the shutter controls in the week after the house acceptance and/or that’s it and the construction will never be touched again for all eternity. This inevitably leads to accordingly different decisions.

*) EVERY knee joint of a wiring should also simultaneously be an inspection hatch!
