Hi,

I have 3 fibaro roller shutters.
The momentary switches (physical switches on the wall) are working fine - meaning up will get them up and down will get down.
this are 3 venetian blinds.

rollers 1+2 = at 0% = open (switches are blind percentage)
roller 3 = at 0% = close (switch is blind percentage inverted)

created a group where
roller 1 + roller 2 = 0% and roller 3 = 100%.
so they should close/open together.

only roller 3 is being fully controlled by the group, meaning open and closes.
1+2 are affected only in one direction (only open).

1 Is it possible to invert roller 3 percentage bar ? so that 0% will open (same as roller 1 and roller 2)
2 how to get them all working together in the group ?

Thanks,
