Smart home consultation new construction wireless

I don’t understand the locking out part. Because even with smart home, I at least have to have my phone on me to get back in. Same with Somfy. With a fingerprint lock, I can almost never lock myself out ;) It would be more effective to control everything by voice and not install input devices like light/shutter switches and even thermostats at all. But who actually does that ;) The company I work for manufactures devices and sensors for building automation. Currently, we are working on a system that tracks users' smartphones via ibeacon signal. This way, for example, it can be determined how many users are in a room to inform the ventilation how much fresh air it should provide. In case of an evacuation, you can see where people are still located in the building. At the airport, for example, you are automatically guided to the gate via your e-ticket, etc. That is smart and useful. That half the employees at a large German corporation left their smartphones at home on the second day of a field trial so the boss wouldn’t see how often and how long they are in the coffee kitchen is another story :p The smart home in a single-family house is just very costly and, in my opinion, unnecessary installations and nice gimmicks for tech fans ;)

Well, you can take the risk if you rely on reputable manufacturers. In the worst case, there are radio actuators like EnOcean, Zigbee, etc.

Yes, these functions (except for the washing machine) are nice , but if you compare the costs of installation and commissioning, you can run the dryer, the heat pump, and the dishwasher for decades at a cost of 0.50 euros per start.
Such a partial solution never pays off...
Not even if I’m an eco-freak, because the production of the individual devices and their disposal are not proportional to the "green electricity" used from photovoltaics.
It gets even worse when a power storage system comes into play.

And: I can definitely preset times for the dishwasher, washing machine, dryer, etc. on the device itself.
What good is it if the devices only turn on when the photovoltaics are supplying power, but I need the laundry, dishes, etc. immediately?

Sure, there will always be scenarios that require immediate use of a household appliance.

I also don’t want to overwhelm those with such an idea.

My definition of smart is that it should support people as much as possible but not isolate or patronize them.

So my Siemens dishwasher has WLAN capability and can be addressed via an API interface. The only thing you still have to do by hand is to start the device and press the button for remote triggering. From that point on, I can start the device via smartphone or API.

If you extend this further, and in the future all household appliances have WLAN, which will definitely happen, you only need one system in charge.

All you then need is a Raspberry Pi. On it, you run the iobroker (free of charge). The iobroker can now connect so many devices that it's incredible. And more are constantly being added. There is also a huge community providing support behind it.

So it doesn’t get any easier than that.

I don’t understand the locking out thing. Because even with smart home, I at least have to have my phone on me to get back in. Same with Somfy.

Completely the wrong way to think. As you yourself have noticed, the phone is not the right solution at all. Sure, there are people who cannot part with it. But most would rather just leave it somewhere in the house. Therefore, the roller shutter/blind should not go down at all as long as the residents are still in the garden.

In a smart home, you should not be forced to remember to take the phone with you before going outside. The necessary technology should function as inconspicuously and securely as possible and ideally be invisible and operate almost without manual intervention.

With fingerprint locks, I can almost never lock myself out ;)

A possible approach to master the task, but you are still forced to walk around the house. Which is, again, not smart.

It would be more effective to control everything by voice

That is also not the best solution but works quite well nowadays. Unfortunately, most solutions have problems with data protection. However, it is a good addition because many tasks are often completed faster than you can say the command.

and not install input devices like light/blind switches and thermostats at all. But who does that anyway ;)

Here you are getting closer to the matter. Exactly that has been done by system integrators for decades. As few control points, thermostats, etc. as possible because, basically, many are completely obsolete and only due to conventional wiring. And many immediately agree that such a piano on the wall neither looks particularly good nor is functional.

If you eliminate conventional wiring, you suddenly become much more flexible regarding control points as well.

In a single-family house, these are only very costly and in my opinion unnecessary installations and nice gimmicks for tech fans ;)

The actual extra cost is often less than one might think. Because you always have to consider the entire trade and need a proper company that knows what it’s doing. Of course, this area still gets exploited as long as possible. The numbers you sometimes see here in the forum alone (regardless of the system used) make you shake your head.

Nevertheless, such an intelligent home is contagious and you quickly get used to it. You also get much more information about the house and building technology, and many things run automatically that you would otherwise have to think about.

If you spin this further now and in the future all household devices have wifi,

Well, WIFI rather not. Too insecure and too power-hungry, etc. It will most likely be some other standard.

There are just things in the single-family house that will never die. I also count switching points for lights among them. Comparable to the volume knob in the car (which has also been tried to be eliminated by buttons), the user blindly reaches out to switch the light on/off. It is ALWAYS the user or their preferences themselves that override a well-automated building and make regulations redundant.

I stick to my point: To really make a single-family house intelligent, you pay a fortune relative to the total construction costs!

I still don't get your example with locking out. How is that supposed to work without sensors in the garden? Window contact is out of the question because many keep the patio door closed for the insects.

There are just things in a single-family house that will never die. I also count control points for lights among them... users blindly reach there to switch the light on/off.

Yes and no, you don’t have to blindly reach anywhere if the light is already on because you entered the room. Try it out. As long as the sensors work well, you can easily do without these unnecessary movements. You just walk through the rooms and the light "follows" the person, and if you use predictive sensors/algorithms, the light in the room/area where the person is heading even turns on a bit earlier—before actually entering.

In my case, we have eight control points in the 11 rooms of the house, of which four are regularly used, two very rarely, and two not at all. It turned out that these are not necessary in a household of four people.

So in my opinion, way too much importance is attributed to the light switch. Most people can’t imagine how it should work, because they often lack imagination or compulsively want to hold on to the supposed control over everything.

So yes, I only partially agree with you. The light switch will never completely disappear, but it will most likely only be used where it is really necessary.

It is ALWAYS the user or their preferences themselves who override a well-automated building and make regulations redundant.

Sure, because there will always be exceptions to the rule. But even these can sometimes be calculated and mapped in advance. Good automation adapts as well and is not set in stone.

I stick to it: To make a single-family house truly intelligent, you pay a fortune relative to the total construction costs!

We’re out of the ’90s. The technology and electronics have become so cheap that much of what used to cost the price of a mid-range car now costs as much as a Vespa. The advantage of a networked building is also that you don’t need everything duplicated triple times (as opposed to stand-alone solutions); many devices can take on multiple tasks, thus drastically reducing costs.

Also here our example: the total costs for the electrical trade were about 10% of the construction sum. But of course, you can also push it higher and spend five times as much. But you don’t have to.

How is that supposed to work without sensors in the garden? Window contact is out, because many who close the terrace door do so for the insects.

It is always an interplay of several input variables. It is never just a single parameter that maps the behavior of the residents. The window contact(s) obviously belong in the mix. Sensors in the garden make the whole thing even more precise (and easier to implement), but if necessary, it also works without them.

well, of course I can equip everything with motion detectors or presence detectors, but I also often have situations where, for example, I do not want to turn on the light when entering the room. Typically in the children's room. As mentioned before, I work professionally with building automation, where everything you write about can be implemented. However, different requirements apply here that are only partially applicable to single-family houses. The devices have become cheap in part, that's true, but commissioning by a professional is getting more and more expensive... The fact is also that licensing for KNX is also becoming more expensive!
