Hello, Yesterday there was a general electrical problem. Since then, part of my Somfy curtains inverted their rotation. I tried the procedure of pressing up and down in the same time but nothing happened. I have Somfy Yokis box in the derivation box of the 3 curtains that have problems.

I tried the other procedure of turning off/on/off the electricity but I can’t do it separately for the curtains, so if I reset them I’ll be stucked with no curtain functional.

What can I do ?
