logistic filter for item?

[kuchenmann]

Hi,
is there a simple way to filter the amount of specific items in the logistic network?
For example if you just want to unload items from train if there are not enough of these items in logistic network?
Thanks.

Click the center button on the top and you can connect an inserter to the local logistics network

Thank you. Yes, this will work.
But what, if I just want to see specific items which are in my logistic network?
When moving mouse over a chest, I see all the stuff and it can be hard finding just the items you want to see.
My solution: First multiply all items in logistic network by "-1" with arithmetic combinator, then add all items you want to see with a high value like "10000" using constant combinator.
Then use decider combinator which is set to "> 0" to get out all items greater zero. After that decrease by "10000" with another arithmetic combiner. Then using another arithmetic combiner to multiply by -1 so that values are positiv again.
I also set another decider combinator which is set "> 0" at the beginnging of calculation-logic, because some items might be below zero when requester chests are requisting more than available.
