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

And all of this is possible without a bus system

Which manufacturers are shown in images 1-3? Are they all Gira?

No, only the first one is from GIRA.

It usually depends on which switches and motors you end up using. Some manufacturers have specific features, and yes, everything can also work without bus systems.

So, that would mean I install a timer switch on the ground floor and the upper floor. These would then use a normally closed contact to activate the respective switches for opening and closing the windows, and the blinds would move accordingly. From the switches, the open and close contacts would go again to the respective blinds, allowing me to operate them individually. Additionally, does the switch need to have an isolation relay installed?

As mentioned, there are different options and systems, but yes, you can do it the way you described.

In addition to GIRA, other manufacturers also offer ready-made switches with auxiliary inputs, meaning switches that can be operated from another location.

It would be simpler, for example, with Homematic IP. You don’t need special wiring; you place a switch on each roller shutter (although this is optional) and have a central unit that communicates wirelessly. You can then pair additional switches, remote controls, smartphones, and various automation functions with this unit.
