The English version of the manuals is available from the zwave alliance site, so that’s fine. 
I have a couple of thoughts, but since these are quite new devices, let’s start with the simplest: what security level did these join at? (Check all the devices.)
Zwave only allows direct association between devices at the same security level, so if the switch is joined at S0 and the shutter is joined at S2, the shutter will ignore commands sent from the switch.
I believe you will be able to see the security level in the API browser plus details screen.
