Wiring diagram for electric roller shutter up/down control via switch and microcontroller

Welcome,

i would like to control an electric roller shutter (up/down) from two places based on the principle of the operation of a staircase switch, the first place being classically a dedicated switch, and the second place being connected via relays (at least that's what I think) so that these are then controlled from a microcontroller, ultimately remotely, wirelessly.
I don't know how to connect the wires to make this work. Does anyone have a diagram?

Regards

Cristof

Intermediate relays must be used.

Thank you for your answers.

They will not be connected to the control panel as I do not plan to have one.

You mean the intermediate relays between the switch and the roller shutters, is that so? If so, this is what I was thinking of.

Best regards

Cristof.

Relays will be controlled from 2 locations and will protect against command collisions.

As Zbigniew's colleague wrote, relays will solve the problem, but you need to be aware that during the whole cycle of raising or lowering the roller shutter you have to hold the G/D switch button which has to be "momentary". If you want another option you can use a ready-made one.
