Roller shutters with a switch and central timer, is that possible?

Hello everyone,

I am currently building and have a question about the roller shutters.

1) We would like our roller shutters to all go up and down simultaneously with a central timer switch (morning and evening), and then operate the individual roller shutters separately with a switch located directly at each window.

Is that possible with a completely normal classic wiring? I heard something about a relay or isolation relay.
If this is possible, what would the wiring look like?

2) And for the individual roller shutters, do you have to install a junction box for the electrical cable at the respective position, or would a completely normal flush-mounted box also suffice?

I would be very grateful for a few serious and good pieces of advice.

Best regards
Gerd

Yes, that's possible, of course it's easier with radio. But the wiring looks something like this:



or like this:





depending on which motors and switches are used.

Is it possible to have both? Switches where I can operate the individual blinds separately and then a timer switch for all the blinds on the floor? Or are both shown in the last picture? Does a separating relay definitely have to be included?

Yes, both are certainly possible. The first picture shows, for example, an individual and central control.

The last picture shows two groups, i.e. 2x 4 windows.

Each group can then be operated either individually or together.

So basically, any conceivable configuration is possible; the more blinds, the more cables and isolation relays.

That means I need 6 wires going to my switch.

Regarding the first picture,
I have two motors M1 + M2, next to them are the switches.
And on the far left is my timer switch which controls my switches and then they control my motor, or how is it meant in the picture with the terminals 1 and 2 on the switch??
Do the isolating relays have to be installed directly at the switch?

And are these special switches from a specific brand?
