Connecions between rollershutter Faac TM XX ER-ERO with Shelly 2.5

Hello to everyone,

I have a faac rollershutter (TM xx ER-ERO) that works by RF. The rollershutter only have 4 wires (brown --> L, blue --> N, green/yellow -->ground, and red) as you can see in image below

In my case, i don't have any switch, so the only the the blue wire is connected to the main Neutral and the brown is connected to the main Phase. In that situation i can work by RF. But i don't want only depends on RF, so i would like to have second system in case that the command control doesn't work and i think to use shelly.

In case that I plug the red wire into the O1 of shelly, then the rollershutter goes up or down, just when i press button "OPEN" or stop when press "PAUSE", if i press button "CLOSE" don't do anything. How i need to plug my rollershutter to the shelly, that also button "CLOSE" works?

Thanks for help!

Thanks both for reply.

So in that case (if i use a shelly1 or shelly 2.5) i never will know the the state of the rollershutter, really?

SebMai , when you say, "So you can't open or close by %.", you mean that i can't open or close by percentatge, really?

thanks
