Blinds motor with impulse command

Hi,

I'm tying to install Shellies 2.5 in the roller shutters of the house we just purchased. Works fine in most but for 2 shutters. The motors are from a Polish company, STARCUS, (model ER). They are supposed to work with a pilot but can be hard-wired as well.

The problem is that that there seems to be a relay inside the motor itself which works with a momentary switch on the wall (black wire and white wire). There doesn't seem to be power going to the switch.

1 click, the shutter goes down, 1 more click it stops, 1 more click it rolls up again...

I can't think of an elegant way to connect that to a shelly 2.5.

Do you think doubling the switch wires and connecting them black on SW1, white on O1, second black on SW2, second white on O2 might work? Then I might as well use 1L?

Any other idea?

PS: the motor itself has limit switches, so I'm not worried about having to stop it when the blind is fully up or down.

Thanks.

That's probably going to be the way. Or a bridge to connect to the remotes.
