One central relay might claim to handle 5 amps. But if you close six powerful shutters at once, the inrush current (the surge when motors start) could spike to 10 amps. Result? Fried relays and a house where half the shutters are stuck at 30%. A good schematic includes a power calculation in the margin.

More modern and wire-efficient is the (often called "fil pilote" or pilot wire). Here, the schematic looks less like a star and more like a daisy chain. One central relay might claim to handle 5 amps

A central switch needs a neutral wire at every control point. Many a DIYer has wired a beautiful central switch, only to find the shutters twitch erratically because they used a simple "two-wire" switch designed for lights. The schematic must clearly show the neutral return path, or you get a phantom shutter poltergeist.
