ᐅ Venetian Blinds and Roller Shutter Motors – Is It Possible to Retrofit Wireless Remote Control?

Without a live wire, the switch couldn’t control anything with conventional wiring....

Yes and no. The question is not about the live wire, but about the neutral conductor.

It depends on how the motor is wired. In my electrical setup, I insisted that all three conductors are present – there are installations where the neutral conductor only goes as far as the motor.

Well, theoretically you could run a single conductor there. But does anyone really do that?!
NYM 3x1.5mm (3x0.0059 inches) cables make up the majority in conventional electrical installations.

NYM 3x1.5mm (3x0.06 inches) cables make up the majority in conventional electrical installations.

yes. Tip into Google "roller shutter switch without" and see what it suggests as a search term :P

Just because the switch doesn’t require a neutral wire doesn’t mean that a cable with only a single live conductor was pulled there. That’s what I’m trying to say. The electrician has a roll of NYM 3x1.5mm cable and uses a few hundred meters of it in a single-family house. And for roller shutter switches, they come with a different cable just for that purpose?
That would be incredibly foolish. But it can’t be completely ruled out, yes.
The original poster will probably have to check that themselves.

That would be ridiculously stupid. But it can’t be ruled out, yes.

They usually take the cables from the roller shutter motor, those are long enough.

Take a look inside your setup.

I insisted on this and have all three wires down there, but not all are standard installation cables; some are thinner copper-stranded ones. The ones from the motor.

I also paid a flat extra 200€ for all the flush-mounted boxes to be deep boxes, or even double-deep... otherwise, the cluster of Wago connectors wouldn’t fit behind the wireless switch at all...
