I've tried to automate a reactor with a track upgrade in a machine buffer, but it didn't seem to have any effect ("0 Items found in the reactor to Track", although there are items that are configured to be tracked).

Switching modes also wasn't documented in the tooltip or the wiki, it took a while to figure out how to switch modes.

The wiki mentions something about linking the upgrade to the reactor by right-clicking it, but that isn't possible, only switches the siding, and likely the cause of the bug.

you need to click it with the side inventory key to bind it.
And yes the upgrade is janky. Its implementation was done at the end of the development ciricle and problems with the usability (only how annoying it is to use) were not made do to being burned out of mc modding because it was a 1 year project.

Ok, the linking with the reactor worked, it says it's tracking, but it doesn't extract the cooling cell, even when at zero durability.

I guess I should stick with my Integrated Dynamics system for extracting damaged cells, which is much more complex, but works reliably.

I suggest removing the reactor tracking upgrade altogether when a new small bugfix patch needs to be released, as fixing it may not be worth the effort (since I'm probably the first person trying to use it).

Well, Integrated Dynamics allows for reading NBT data and I used it successfully to read the ReactorHeat-tag of the reactor block as well as advDamage-tags on coolant cells in the reactor.

Anyhow, I still haven't gotten the tracking upgrade to work fully: It extracts the wrong items in the slot, how it's supposed to be, but doesn't extract coolant cells, regardless of damage (I've even tried at exactly 90% damage). Insertion mode works fully, but I haven't got extraction mode to work. It's not just limited to coolant cells, but heat vents and heat exchangers also don't extract, I haven't tested the rest of the extractable items, but it's very likely that the extraction mode is bugged entirely.

I've also tested 1.4.0.0 to 1.4.0.2 and it doesn't seem to work there either. I've lost my bookmark to the 1.10 pre-releases, so I couldn't test if the bug was always present.

I didn't expect another content patch to release, but I'm not complaining.
Thanks for you efforts.

well when you bind it to a reactor it takes a snapshot of the layout and then tries to enforce that layout @Erik3003
thats why it is not working for you in most of the cases.

I've re-linked it to the reactor (with the cells or other things inside) every time I made changes, I don't think that is the cause of my issues.

@Erik3003 it only sucks out the "Durability" items when they are at 90% or more damage. And it only inserts items when the slots required have a missing item.
Also the Upgrade direction needs to face the reactor/chamber from the machine buffer (if that side is not right it wont take/insert it).
Same goes if the item does not match then it will extract that item too.

Also about other mods doing this. Good luck I made this upgrade so you "Actuall" can automate the "Coolant" options because the "Durability" you see is not the Durability that other mods see. What other mods can see is the "Type" of the coolant cell, not its durability because thats stored in the NBTData under a tag. And there is little to no mods that can say "ReadNBTInteger & Compare" like they do with ItemDamage.

There will be soon a content patch with additions that may or may not address that issue.

I am not happy with that upgrade either but back then everything was a bit more different for me.

Edit: And no you are not the first person who used it. That would be me. And i used it extensivly in my testplaythrough on a server with a couple other people. Its just that it is a "Pain" to use until you understand its limitations.
