dst_endpoint not reflected in binding

[kdsp-net]

Hi, I'm trying to bind several wireless sensors (Sonoff SNZB-02P) to my UFH Controller (Ubisys H10). I can bind the sensor to the temperature measurement cluster on endpoint 1 withou any problems but when i try to set the dst_endpoint parameter to the second sensor it gets ignored and the sensor gets bound to the endpoint 1 regardles. Here is the command log:

    dst_endpoint_id: 1 <-- here the destination is "1"
    cluster_id: 1026
    result:

I have also contacted Ubisys since I'm not sure who's "at fault" here.
