I, i'm trying to set a blue chest on Produstia floor and ask for several items to automatically replace on ground floor when there is some attacks (specially Gleba ><)
I've put some request on the blue chest and, on the ground, the red chest serve it to my base. But when smeting is missing, , it's filled up by another one so i've got trouble to maintain everything. How you guys are doing that ?

I've tried to limit the size of the chest to get one stack of each one but it failed. Same for the other way around when i'm trying to request from ground to produstia. Is there a way to accomplish that ?

with logic:
- count the surface item with a roboport
- set negative quantity of what you need
- add both value and every negative quantity left you pass them to the other surface (then you make them positive and use as "set request" on blue chest) on the teleporters between both surfaces.

this way you call items in other surfaces and stop calling when you're full

Not sure to see it all but will try. Thanks for the tip ^^

Tried but can't seem to know how to pass the signal to the other surface....

ok, found it. I think i've found a simplier way to do that.
- On my roboport I can send the request from the logistic network.
- I link my robotport to the player teleporter
- I link my blue chest on -1 to the player teleporter
- I check the option to create request according to the network on the blue chest.

This way, anything requested on the ground floor will be requested on the -1 blue chest. I can let the things to be place be requested on the fly or add a blue chest on the surface to create some spare in advance
