External roller shutters - how do I apply a system similar to Zamel to controllers from other manufa

I have 10 external roller shutters to connect at a customer's house in such a way that there will be several levels of control. Roller shutter -> room -> floor -> house. Originally I was going to put controllers in the boxes and use the inputs of the central buttons, but with Zamel for example (and I think F&F too) this can be solved with suitably connected diodes. There are already local controllers in the roller shutters themselves, the problem is that I don't know which ones. Can anyone playing around with such automation tell me whether an arrangement similar to Zamel's can be applied to controllers from other manufacturers? This would make my task so much easier that I would only have to mount (in some safe and sensible way) these LEDs under the buttons and there would be no need to buy controllers at all.
