I/Overseer

About this project
What does I/Overseer add?

I/Overseer lets you watch every machine in your base, from any mod. Hold the tablet and see at a glance what's working, what's idle, what's full and what's out of power. It's made for kitchen-sink packs and needs no per-mod setup.

I/Overseer Tablet
- Use it to list every machine within 32 blocks, grouped by mod. Each one shows as Working, Idle, Output full or No power.
- Filter tabs show only one status.
- Click a machine to see its energy, fluids, slots and position. Ars Nouveau Source and Mekanism chemicals show up too when those mods are installed.
- Ctrl-click a machine to find it: a gold outline that shows through walls, a light beam, and a HUD arrow with the distance. It clears when you get there.
- Sneak-use a machine to pin it. Pinned machines stay in the list from any distance or dimension, and you get a toast when one runs out of power or fills its output.


Live preview
While you hold the tablet, its screen shows the power draw of nearby machines in FE/t with a 16-second graph, a stored energy bar and the status mix. Turn it on or off with the Preview button in the tablet screen.

Pin alerts

I/Overseer Screen
A wall monitor that shows a live status list on its face. Right-click it for the full view.

Works with any mod
I/Overseer reads the standard NeoForge energy, item and fluid capabilities, so most tech mods work out of the box. It was tested with Mekanism, Powah, Applied Energistics 2, Ars Nouveau and Create (every block that draws stress is listed. Details show its speed (RPM), the network's stress against capacity (SU) and the SU it uses. The held tablet preview shows nearby SU use too.)

- No power: the energy buffer is empty, a furnace has input but no fuel, an Ars machine has no Source, or a Create machine is stalled or overstressed.
- Working: the block shows a lit or active state, or its contents changed in the last few seconds.
- Output full: the machine is idle and a slot or tank is full.
- Power draw uses Mekanism's own usage figure. For other mods it's worked out from the drop in stored energy.
- Chests, energy cells, cables, tanks and AE2 network blocks are skipped. Packs can add blocks to the
ioverseer:ignoredtag to hide them, or toioverseer:machinesto force them in.
