Aeotec trisensor led alarm led remains on

Hey guys I like the aeotec trisensor but i just want to turn off the green LED activated by motion alarm sensor. I am using the sensor dirrectly connected to homey via Z-wave and there is a setting to deactivate the led but it seems to me that the setting has no effect on the sensor. Does anyone have the trisensor and has been able to turn off the led?
