Best retrofit smart home new build

Rules that really?

Depending on the system you choose, everything ranges from fully manual to fully automatic.

But don't controlled residential ventilation systems just have 3-4 levels and actually constant airflows for each?

The one who pays... also decides on the type of control. Most builders don't want to deal with it or pay more for more options and just end up getting the step selector switch.

but is that done?

There is no patent recipe. You can measure one or several parameters per room, or per floor, or even only within the system. How the control algorithms look then is up to you with the appropriate equipment.

KNX and door lock initially have nothing to do with each other. You can connect the two, but some do not want to for security reasons. Although I do not see how that should be a disadvantage if there is a separate outside line.

At least I have implemented the following with us:

[*]I have additionally connected the two relays of the fingerprint reader controller to KNX binary inputs. This way, the KNX system already knows that someone is entering the house and you can, for example, disarm the alarm system (certainly not VDE compliant). After moving in, you will probably think of even more evaluation options.
[*]I initially let the controller’s push-button inputs switch actuators. Whether I will actually use this, I do not yet know. The security aspect mentioned above also comes into play here.

In new buildings, you solve that with a motor lock and fingerprint/RFID reader. Nothing runs on battery and you don't have an ugly box on the lock like with retrofit solutions.

The fingerprint scanner from Ekey at least has live detection. Even if other solutions don’t have that... who copies your fingerprint James Bond style instead of just throwing a stone through the window? (Warning, may contain traces of exaggeration)

The video intercom has nothing to do with KNX, at most the button that opens the door via the switching actuator. Advantage: You don’t need a key and don’t have to go to the door to open it. What else should the advantage be?

A door lock is not smart either, it’s just connected to a switching actuator! I have an ekey fingerprint scanner connected to the intercom, which opens the door lock via KNX. Additionally, there are contacts for lock monitoring. The building control runs on my UPS in the rack, so it should survive at least an hour of outage. Otherwise, the door still has a completely normal lock and the key is with my parents-in-law :)

How would you make the smart door lock run, is it battery powered?

What is a smart entrance door?
No
No
What is a smart door lock?
Our motor lock is powered by the house electricity. Why would it need a battery?
I find fingerprint scanners impractical and seemingly insecure.

Did you make the front door smart in your KNX system?

Yes, the door should report whether it is open/closed/locked.

Have you installed a video intercom system on your KNX system?

If you need it, it’s not a problem. However, it is often a costly factor regardless of whether you connect it to KNX or not. This is because mostly proprietary systems and buses from manufacturers are used here. With pharmacist prices. Which are then sometimes connected to KNX via SIP.

What are the advantages and disadvantages of the smart door lock?

What does smart mean to you regarding a door lock? There are quite many variations and interpretations of this term. Generally speaking, the advantages are also the disadvantages. For example, if you can open it remotely, then you have to make sure that no one else can do so, and that is sometimes a very difficult task.

How would you make the smart door lock work, does it run on batteries?

You have to ask the manufacturer of the preferred lock how they have solved this.

How secure is it? How secure would a fingerprint scanner be? (actually very insecure on a phone)

It is as secure as you feel it is. To put it simply, it is not more secure than a key. Exactly where the strengths and weaknesses lie is always shown by tests. Results can often be found relatively easily on the internet.
