Bacnet problems LM

[Alexander]

This is just a scanner, you should scan each time you want to see update.  The bacnet client app is pooling for mapped objects so in there you should see update.

Ok, but I could not use the client app because it was to much objects. 
So I try to do this in LM. 

I use Mosaic for lighting and heating control (knx), and I want to use Mosaic to read values from my bacnet device (ventilation). 
Can someone please tell me how I can do this the easiest way
