Light control: INT-ORS Satel expander + conventional switches

Welcome to the esteemed group. 🙂

I am about to have my electrics laid out. I'm delving into the subject of home automation, as I'd like to be able to control the roller shutters and lighting at my home from the control panel (via an expander) as well as from traditional switches.

Searching the internet for wiring diagrams, the ones described by pik_1 on this forum seem interesting.

Light and roller shutter control - INT-ORS satellite expander .

The control of the roller shutters is clear to me. However, I have a question regarding the lighting scheme. I have the impression that the presented scheme prevents the simultaneous use of traditional switches and the INT-ORS expander. Let's assume that I am activating bulb C1 via the Expander - can I now switch it off via a traditional switch? In my opinion, no.

Below is a diagram I have drawn. In general, nothing revealing - an application of a stair switch diagram so to speak.
A 3x1.5 cable from the bulb to the box and a 4x1.5 cable from the box to the expander. Terminals C1, C2,.... are connected directly to voltage, unless you want to dedicate the last terminal Cx to switching off all the lighting (as in the attached diagram).

.

What do you think of this solution? Is it optimal or can you think of something better?

PS. One more question - maybe someone knows: with the application installed (from Satel) on a smartphone, is it possible to read whether the bulb is on or off? I guess that having INT-ORS expanders we can only see the position of the individual relay (whether it is in NO or NC position), and since the bulb can be on at both NO and NC (depending on the position of the traditional switch) we don't have that possibility?

I would appreciate your opinions!
Greetings!

If you want to know the actual state (and use it) then you can use the inputs of the control panel and connect e.g. bell switches to them - a click changes the state to the opposite on the output. The condition would be that the switchboard is working properly (in case of a fault there would be no lighting control).
With a staircase system, you don't know if the light is on or not - you would have to check this in a different way (e.g. detect the power supply and feed the information to the input), but this complicates the task.

If you want to make your life more complicated, check out ROPAM's solutions - their roller shutter and lighting control modules can be autonomous and do not require a control panel to operate, although once they are integrated into the system, you get full control capabilities and feedback on the status of a given output.

Although I should add that in Satel also the output status can be visually shown on the app or keypads.

Gentlemen, thank you for your comments! .
I did some more searching and found a schematic along the lines of what sk1977 .
Except that instead of INT-ORS I'm going to use INT-IORS, which also has inputs (so as not to pull cables to the control panel).
I will use bell buttons that change the relay state on the output.
Below is the diagram:

.

It's also advantageous that to make two or more buttons to switch on the same light source (read: stair/cross switch), you only need to pull a 2x0.5 wire from each successive switch to the expander and connect in parallel to Z1 and COM.

However, another question arises - let's assume that I would like to do it in an analogous way for roller shutters, below is a diagram:

.

Only that in the above diagram the roller shutter button should work slightly differently.

In the first diagram, clicking the button changes the state to the opposite (from NO to NC or from NC to NO).
In the second diagram, pressing the button should change the state on the output to NO, but when the button is released the state should return to the original NC position. Do you think this is programmable in DLOADX ?

Or maybe someone of you already has a roller shutter control from Satel and could comment/share the schematic ?

PS. adwlodar Thanks for the pointers to ROPAM - I'll have a read.

There is a lot of information about controlling roller shutters with Integra - also on the forum.
On the Ropam website you will find an example project for controlling light, roller blinds, heating and other elements (https://ropam.com.pl/pomoc_techniczna/). Additionally, if you have no experience with alarms then Ropam is probably more intuitive.
