Which control for external blinds should I choose? Cabling 4x1.5 vs 5x1.5

Question

Hi, I am looking for some help with the control of external roller shutters. I should also add that I am a total layman when it comes to automation and electrics. I have a pre-made installation for the roller shutters and am wondering if this makes sense/will it work. The design looks like this:...

No way, at least not in this way. In order to close/open all the roller shutters by remote control, you would have to use a radio-controlled roller shutter controller in each switch box and assign all of them to one (several-channel) remote control. In this case it is not possible to control the roller shutters with some kind of controller in the switchboard. An alternative is a Wi-Fi control, e.g. Zamel's Supla. If you used a 5x1.5 cable, you could have central control (you go out/enter the house, press the button by the door and all the roller blinds go up/down; you could also connect this switch with the alarm control panel - disarming lowers the roller blinds, disarming - raises them), group control (the button lowers/raises a group of roller blinds, e.g. in a single room or a group of rooms) or local control - each roller blind individually. There are many solutions, I have given only the simplest, most common ones.

Thanks a lot for the reply. That's what I was afraid of, something told me it was impossible to control 3 x 1.5 each, I don't know where this electrician got the idea. I have one more question. I have to get out of the current situation (the bathroom and the kitchen are already plastered and I can't change the power supply to 5x1.5), if I run a cable like the one for the alarm 6x 0.5 between the roller shutter buttons and connect them in series, could I have an additional main button which would close all the roller shutters? Is this solution associated with any additional costs - I mean, would I then have to buy any special controllers for the roller shutter buttons?
Best regards and thank you very much for your help.

I mean, you can, wirelessly (radio/Wi-Fi control) but there has to be a controller in each window and it has to be radio-controlled - it does make the cost a bit much, but group control (and probably even central control) can be done - although it will be difficult to combine it with the house automation. Wired control would be more convenient and easier to possibly combine with e.g. an alarm or automation, nevertheless, there would also have to be controllers in the boxes anyway - although definitely cheaper. Both types of controllers use 230V power supply, so the use of YTKSY or YTDY (alarm) cables is out of the question due to insufficient insulation resistance of the cable; instead, you can use a two-wire cable e.g. OMYp 2x1.5 (although these colours ) or similar only to control roller blinds, for their power supply the one already laid is sufficient. BTW, how many roller shutters are there and on how many electrical circuits? Because I read in the first message that a separate cable runs to each roller shutter from the switchboard? And deep or extra-deep boxes would be useful under the switches. PS. You could also use two relays instead of the modules and then you could use these pasta cables, but then the power supply for the relays would only be low voltage, the control would be difficult and there would be an additional power supply only for them - I would be against it, if only because of the proximity of the high and low voltage installation and thus the danger in case of a possible short circuit.

There will be a total of 14 roller shutters. At the moment, almost every roller shutter (I could make it so that there is one for every roller shutter with little effort) has its own power cable (each roller shutter on a separate es). All the power wires are routed out to one switchboard. From the electrician before he abandoned me I had information that for the switchboard I would have to buy :
1) special modules - I think it was marked SEP (signal separator?)
2) a controller

Best regards

For rich.... SEP-01 (in the switchboard) or SEP-02 (in the box) are used to separate/separate a group of blinds, for example for several windows in the living room. But these separators are used to separate control signals, which your installation lacks. Without control cables they are useless. What good is a controller in a switchboard (which one?) if we do not have controllers for individual shutters...? What are these roller shutters? What colours of cables are coming out of them? .

I would like to install roller shutters in the future, I haven't chosen a model yet, right now I have just the 'cables' on the façade.
I have commissioned an installation for the roller shutters with the possibility of controlling locally from a button by the roller shutter and "all" with one switch/pilot "close all/open all". As you can see I was pretty well cheated on the material (why do I need a separate cable for each roller shutter ;/).

I've analysed my situation, and I guess the most sensible thing to do now would be to connect all the "switches" for the roller shutters with the 2-core cable you mentioned, and thus gain the ability to send a signal to close/open all the shutters (unless I'm wrong :/).
Just an additional question, is it better to run this cable between the "switches" or to run a cable from each switch and exit with them in the switchboard?
One more question: if I make a "master" button per floor, if I connect these main buttons with a 2-core cable, will I get a button controlling all the floors? (I have 3 of them ;/)

Thank you very much for your help.

3 power wires to the roller shutter and in the boxes insert a Zamel Supel, this works over WIFI. You then have control, individual, group, schedules etc. All controlled by phone. I recommend, I have 40 units, 0 failures for 3 years.

First of all, I wouldn't be ragging on statements like:

You are the one who claims that the electrician said so, but you wrote that

so you might have mixed something up...(e.g. are you sure in the switchboard? Do you have space there for at least an additional 14 modules in addition to the 14 eSecs for the roller shutters?)

Why did he abandon if I may know?
The electrician was rather referring to the SRP type modules (22 exta life) of Zamela and the controller/controller e.g. exta life controller efc01.
Did the electrician put in recessed switch boxes?
The power supply to each roller shutter from a separate eSki is a good solution. If one motor or module fails, the others will work. Imagine a situation where all the shutters are closed and then "boom...". the eSka from all shutters flies out. Not to mention the programming of modules or radio motors (where switching the power off and on activates the programming mode of all modules or roller shutters at once....
