Wired Smart Home Integration: Satel Integra + INT-KNX-2 for Old House Renovation?

I'm doing a complete renovation of an old house and I wanted to integrate it a bit so that it could be controlled from a mobile phone and a wall control panel in the house.

I am interested in combining such systems as an integrated video intercom with the function of calling to a mobile phone, alarm, control of the entrance gate, control of the garage door, control of heating, air conditioning and possibly cameras + DVR (it will be Dahua).

For the moment I'm considering Satel Integra + INT-KNX-2 (because I think it needs it) with some kind of touch keypad, because I can see that it's nicely designed, but for that I know there are problems with video intercoms. What specific keypad video intercoms are supported?
Maybe you can recommend something else? Or take the smart alarm from Dahua separately ?

I am only interested in a WIRED system !

There are already quite a few toys for KNX on the aftermarket, just remember that in order to program anything you need to have a legitimate ETS soft and a few things without which you can't do anything with KNX blocks. The system is generally very flexible, but not intuitive. Its intelligence depends on the intelligence and experience of the programmer. Generally speaking, the places you want to control need to be wired up, with a normal 2x2x0.8 EIB trunking cable, but if you are planning a control panel, you will need two such cables, one for transmission and one for power supply. In some solutions where you use power ports, e.g. for motion detectors, you will need to supply additional voltage via the bus cable. In the demo version of ETS, you can program up to 5 addressable pads (but you probably know that). I bought the LITE version and with up to 20 bricks you can already create a small installation in a detached house on this. As for using the control panel to control things in the house, I prefer the alarm system to be on typical SSWIN devices and the controls should be implemented on typical KNX actuators and sensors. Then integrate it all on the KNX bus and it's a breeze.

Ok and is this software downloadable somewhere or do you have to buy it? I am only interested in new ones.
I have no experience with this, maybe you can recommend something else panel to control the alarm and so I have to give one at the entrance and in the garage I prefer to be easier to set up.

ETS5 you download from my.knx.org go to the shop download the lite or professional version and fire it up on your PC. As long as you don't buy a dongle, it works with up to 5 KNX blocks, when you buy lite it works with up to 20 blocks. I bought LITE because if you are short of 20 elements, you can divide the project into 2 parts and treat them as separate systems. If you're prof, it's unlimited. It is not an intuitive soft but there is a lot of literature. To integrate, you will need a programming interface for the knx blocks and a KNX power supply. the cost is around 1pkln. and then you are only limited by your ingenuity and your wallet. To sum up, you will need a KNX module from Intergy anyway with another system, i.e. soft knx you must have. Draw a block diagram of what you really want to achieve, because at a general level I can guess, but the devil is always in the detail.

How do you draw such a diagram, do you have any software for this?

A piece of paper, a pen _> a picture from your phone and I'll suggest something:-)

If you have no experience, KNX is not the best system to learn. It is neither easy (intuitive) nor cheap. There are many simpler to set up and cheaper systems - e.g. Ampio, Loxone, Grenton.
Like Col. Szorterek, I am not in favour of combining systems responsible for security with others (if only to a limited extent).

As for the block drawing somehow I don't know how to go about it because I've never done it. I don't require any crazy stuff as long as you can control a few things from your phone.
Possibly Grenton and a Satel control panel for this?
I don't even know where to start shopping. From what I understand, I need to buy a central unit and then add control modules and a wall panel.

Let's summarise, maybe this will illuminate something.

Integrated video intercom with call to mobile - this has to be integrated with something? Maybe just use an intercom app - if it has to send video to a mobile it won't be wired anyway.
alarm - it is best as a separate system (or with the possibility of controlling devices) - Satel, or see ROPAM - in my opinion more intuitive configuration, lower price, touch panel in the price (there are resistive and capacitive ones - it is worth paying attention to that), allows to control various devices, there is an application (it can be paid, recently it was 20 PLN for a year) - on Ropam's website there is a project of a whole house controlled from the control panel - you can watch and look for inspiration.
control of the entrance gate, control of the garage gate - this could be controlled by the control unit.
control of heating and air-conditioning - it is also possible to use the Ropam control unit - with air-conditioning it depends on the model and possibilities, with heating it also depends on what you have.
Possibly cameras + DVR (Dahua) - the manufacturer's application may be sufficient here.

What I want is to have one panel on the wall which will display the image from the video intercom (it is not necessary to call the phone), to be able to use this panel to open the gate, door or garage and to perform the function of a thermostat for heating as usual wired or wireless thermostats do. My main concern is not to hang 4 devices next to each other which will control everything separately. At the moment I've still got absolutely nothing just plumbing the walls, but I know I need to figure it out at the very beginning to get the cables laid properly.

The SATEL configuration is simply tragic, which is true, I don't have a super old one at my company, but to oblige it through the COM port is a disaster and this program is prehistoric.
I am looking at this Ropam and the prices are ridiculous, but won't it fuck up...? too fast ?

As for monitoring it is probably enough I currently have one and am satisfied.

If you want to have everything in one panel and the prerequisite is a cable system it will not be easy - and therefore cheap - .

I don't want any additional signals and it is just my belief that all waves are not good for the human body at all. Somehow I will not be surprised if in a few years people will be dismantling them.

The 21st century and it's really that hard to wire something up? As for the price, it does not have to be cheap, there is not much if it does not cost a fortune then I can manage .

In general, you want to combine different solutions into one system and connect this with a cable and still have everything on one panel - here KNX is the solution, but it costs money. Do the math and assess whether it's a fortune or not.
Panels for everything in my opinion are not useful, I got rid of .

I've been looking at some Grenton starter kit, it's £3500 but I don't need some of that anyway and probably something else needs to be bought.
As for ROPAM I can't find this "house project" and it looks encouraging, can you send a link?

And what did you put in your house?

I am going to install a water underfloor heating system and I want to install a temperature sensor on the floor (to prevent overheating) and I want to install it in the light switch in each room and connect it with this system to control the underfloor heating system and the gas cooker with this one panel (system). Isn't this overkill with these sensors ?

Don't look at starter kits - this is more for demonstration or training - choose what you need.
