Rollershutter and Raspberry GPIO

I’ve got some rollershutter with engine and I would put UP/DOWN command into habPanel UI.
I search on Google and openHAB to find example about control Raspberry’s GPIO with rollershutter but I don’t find anything.
My first choose was
Switch RELE_UP “UP” { gpio=“pin:24 activelow:yes” }
but I think the rollershutter item is best.

I would know your opinion before start work because I wan’t damage rollershutter engine!

Thanks, rodsmr
