IT professionals are usually very biased on this topic.
So, then I dealt with it and especially saw the costs.
20,000 + normal electricity (whether KNX or Loxone) is no small matter,
Mistake number 1... why 20K + normal electricity? Why would you impose double costs on yourself? Or were you just badly advised here? It should say 20K instead of conventional wiring, which usually represents a large chunk of those 20K.
Shutter control - NO (I don’t need to be able to do that from anywhere in the world)
Of course, this has nothing to do with it at first and is mistake number 2... the general thing with smart home, that you equip such houses with automation and mainly do it because then you could control it from anywhere in the world. Whether it’s the shutters or other things. That’s not what a smart home is about at all. That is just a bonus or a function that simply arises as a byproduct and of course can be switched off on request. Also physically on site so that no external access to the system would be possible.
Door intercom system - YES, but this is covered by the TKS provider and since I am alone the app is enough for me.
Surveillance cameras - YES, but this is covered by the camera provider.
A patchwork of apps on the phone/tablet for every subsystem is far from the reality of a smart home.
Mailbox - YES, that would be cool if you have a display at the entrance and a sensor in the mailbox, then you don’t always have to unlock.
Yes, it’s quite useful. Implementation? 2 binary inputs and contacts... so peanuts if you have a finished construct. Something like that just arises because one thinks about this or that function and has the possibility to implement it relatively quickly and easily. Because the house understands when you tell it: Here contacts -> if closed (or open/or sequence of actions/depending) = mail. That doesn’t work so quickly and easily with conventional electrical wiring. Of course, you can tinker something with an Arduino or something, but hey, youth researches for simple mail detection?
Switchable sockets - YES, that would be the 1st thing I would really like to have.
Yes, they are useful because, for example, you save switches/buttons but everything remains operable and scenarios can be played (watching TV, sleeping, away, dinner etc.) and, for example, everything is also turned off and disconnected from power (except of course devices that need constant power like refrigerator, OLED etc.) after leaving the house or going to bed.
YES for presence detectors and different brightness for day and night.
Yes, especially different lighting moods and scenarios up to a simple alarm system are possible with presence detectors without extra costs. You just need these above-mentioned presence detectors and some imagination, the rest you do on the computer. Provided you have something to control. But you do, if we talk about different lighting scenarios day/night/evening etc.
So I came to the conclusion that there is no smart home after all and I will wire everything conventionally.
In entrance hall, bathroom, utility room, guest WC, pantry there will be motion detectors, but they don’t adapt the brightness - that’s all I can do.
That’s your decision and if that’s the case I’m sure you’ll still love your house. However, motion detectors are the little ugly brother of presence detectors. Obviously better than nothing, but I, for example, always get annoyed by the rudimentary settings, the poor detection and of course by the noises of the relays. But that is just my opinion.
"Presence detectors for light control + time-dependent light control can also be regulated autonomously, then that would already be something.
Sure that works, but it comes with many compromises. A little bit here and a little bit there is usually not effective. It’s like buying a Fiat and trying to turn it into an Audi. Why not just buy an Audi or at least a VW. (Brand names chosen randomly).
EDIT: And just laying a control cable into every room doesn’t help either,
because then you have to break open the room from there to lay it to an actuator.
Of course not, that’s nonsense. Because then you are still trapped in the cage of conventional wiring.
Exactly, if I’m not at home (and don’t have a sensor) then I have to tell the window to close.
That’s far from a smart home. Although the term itself is misleading. Nowadays everything that requires even the slightest less interaction is given this title. Formerly we called these things remote-controlled sockets, today it suddenly is smart home as soon as something becomes remotely controllable. But smart is rather what works on its own without manipulations by the resident.
This function doesn’t matter anyway - because too expensive.
In the smart home you usually get such simple things practically for free. Most of it is already on board.
Like a modern phone. When you buy it, you can not only make calls with it but also send and receive messages or schedule appointments or or or. The phone with the rotary dial on the other hand is the equivalent of conventional wiring with the switches on the wall.
