Thaumic Duality Interface

by CaelixOrbit

Thaumic Duality Interface lets an AE2 interface output items and essentia at the same time, so automated alchemy receives essentia on demand.

What it does

A standard AE2 interface cannot output essentia directly. This add-on, built for the GTNH edition of Thaumic Energistics on Minecraft 1.7.10, introduces an interface that outputs both items and essentia at once. Its processing patterns encode both kinds of input, so a single crafting job can deliver them together.

Automated alchemy usually depends on Essentia Providers that supply essentia continuously. Here, the essentia a job needs is counted in the crafting plan, which works out the exact essentia cost of each operation and starts auto-crafting only once that essentia is present, so no task begins with essentia missing. A fluid-based Dual Interface works the same way for fluids, and an Essentia Dual Interface covers the essentia side.

The mod requires Thaumcraft 4, Applied Energistics 2 GTNH Edition and Thaumic Energistics GTNH Edition. It is published for Forge on 1.7.10 only, with the latest file 1.0.1 dated 2026-05-01. Only the server and players who join need the add-on, and it is open source under the GNU Lesser General Public License v3.0 only.

Key features

  1. Combined item and essentia output

    One interface sends items and essentia together, which standard AE2 interfaces cannot do.

  2. Essentia cost in crafting

    The AE2 crafting calculation includes the exact essentia needed for each operation before a job starts.

  3. Closed-loop essentia supply

    Crafting waits until the essentia is available, which replaces continuous supply from Essentia Providers.

  4. Dual Interface variants

    An essentia version and a fluid-based version share the same simultaneous output approach.
