I was wondering, is there a way to check if the logistics system (all storage and provider chests) together, contain a specified amount of an item. I tried connecting the storage chests to the wires but it wouldn't let me.

Thanks in advance

Not directly. The best way to do this at current is to use smart inserters to check the logic network, which then move a dummy item into a chest when a condition is true, and out when it is false. The circuit network connects to the chest, detecting when the dummy item is present.

Hmmmm, very interesting...
It is possible to create such system that will automatically finds the amount of specified items in logistic network using binary search and dummy checking.

If you're willing to use a mod, I made one for that. In my sig, "Logistic Combinators."

constant combinator gui, select up to 15 items/signals, it will output on the connected wire the logistic values for those.
