Hi,

Installed a fibaro roller shutter 3 but when i try to calibrate my sunshade it just stops. I figured out that i have to change the parameter 155.

But how do i do that, the app doesent save my input.

It says: id , size , value;

So i try to add : 155,200,200;

Sometimes nothing happens, sometimes: 155,2,2;  
I restarted the app, homey, changed language but no success…

Anyone had the same problem…?
