If I connect the Shelly 2,5 switch inputs to my existing roller shutter controller will it work ?
Ie drive the Shelly from the existing controller.
The input would not be momentary but would be on for duration of movement up or down.
Ie is the switch input edge triggered ?
Using 240v
Interfacing to existing controller allows in room wall buttons and hand held remote to still function.
thanks 
Hi
@Gah , welcome to the forum.
Do you have any data to your existing controler? 
Hi Stephan
Unfortunately I have no data for that controller
It simply switches the 240v to the motor in the same way that the Shelly does
It could be wired into the 2 switch inputs on the Shelly to activate it and let the shellys relays operate the motor
The problem I foresee is that the Shelly may require a momentary input whereas this would be
In the switch state for the period of time that the roller shutter would normally operate
Would this cause the Shelly to not operate correctly ?

No, the shelly works with a switch properly.
I think, there is no problem. 
Hi Stephan
Found a small document on the controller see attached
