ᐅ Is it possible to operate roller shutters with individual switches and a central timer?

Hello everyone,
I am currently building and have a question about roller shutters.
1) We would like our roller shutters to all open and close simultaneously using a central timer switch (morning and evening), and then be able to operate each roller shutter individually with a switch located directly at each window.
Is this possible with a standard, conventional wiring system? I have heard something about a relay or isolating relay. If this is possible, how would the wiring look?
2) For the individual roller shutters, do you need to install a junction box at each location for the electrical cable, or would a standard flush-mounted box be sufficient?
I would be very grateful for some serious and good advice.
Good luck
Gerd

This can also be done very easily and inexpensively by placing a Shelly2 device behind each switch. This way, you can control all the roller shutters at once, according to any complex schedules or sensor data (brightness), while still being able to use the switches manually. You don’t need any additional wiring, and the software for these devices is open source.
I would prefer to control this through a central controller (PLC) and use push buttons instead of switches—so "momentary presses" rather than "on/off states."
This way, the most recent command always applies, and the signal sources cannot electrically interfere with each other.
By "switching" near the patio door, I mean something different: namely, a lockout or safeguard to prevent the central controller from automatically locking me out because time X has been reached while I am still outside.

It would be simpler, for example, with Homematic IP. You don’t need any special wiring; you just install a switch on each blind (which is optional), and then you have a central unit that communicates wirelessly. You can then pair additional switches, remote controls, smartphones, and all kinds of automation with it.I’m not familiar with that at all. Can I simply program the times with my smartphone, have everything operate simultaneously, and then control each blind manually on site with a switch?

I installed a system like this. The control unit is located in the bedroom. It controls all the roller shutters that are set on timers. The control unit has an astronomical function, which means you tell it to close the shutters 30 minutes after sunset and open them 45 minutes before sunset. Next to it, I have a switch that manually operates the upper shutters and another switch for the lower shutters. There is also a switch at each window for raising and lowering the shutters.
Wiring: at each window, there is positive, negative, and ground wiring. For the roller shutters, I used a 4-core cable, and from the control unit to all the shutters, I daisy-chained a 6-core control cable.
I avoid wireless connections as much as possible to minimize the risk of interference.
The wiring sounds more complicated than it actually is.

There are now Alexa switches available for electric roller shutters, which I would prefer due to their low installation effort. Additionally, they can be operated from anywhere using a smartphone.
