Fibaro Roller Shutter 2 - not opening or closing completely

Hello,

i have problems with 3 of my fibaro roller shutter 2. After having worked for many days and weeks they suddently stop at about 80% and again 20% when opening or closing. (Always the same %) A forced calibration worked without these stops, so there isn’t something in the way of the shutter that lets him stop by himself. There are 7 shutters in my house and the other 4 work.

I use a group with 4 shutters in the basement and 3 of these run completely up or down but just one stops in between…

Do you have any hints?

No idea anyone?

Hi !
I have the same problem, did you find what to do ?
Thanks,
Nicolas
