THANKS @Klonan for the combinators, and @Squish for the info !
Depot writer has an enable condition: Setting the writer with the requested item and a =
condition and a count, will set the depot ot only request that number of items
For others that stop by, I connected it, clicked on the logistic icon in the upper-right, enabled it (even though no logistic network in range), then set it "item=value".
i did almost the same, but used a local network (connected a wire) and almost got desparate when i couldn't get it to work ... to me it would seem to be a more logical way of setting values by giving (constant) values by wire, and not (apparently) reading a (non-existant) value from logical network. setting values by wire would also allow us to dynamically change that limit depending on readings and calculations from other sensors or chests ...
with this functionality, we also don't need other methods any longer to limit the requested amount after researching the stac bonus. no more need for a "overwrite stack bonus" switch in the gui or something similar. this should work even better. HUGE THANK YOU !!!
Road network reader, you choose the signal to read, and it will update with the number in the attached road network.
this worked perfectly for me. i even have set up some kind of "main display" to have all the info at a central location from where i can check whether any resource or product is running low :-) maybe this will be a real UPS-killer in a megabase, but in smaller bases it is real nice. and having one in the pocket (inventory) at all times is very useful when you are wondering why a requester never gets fed some items: just put the network reader down and see whether that kind of items is produced at all anywhere in the network :-)
