AUN Group Controller

By the time a ComfyUI workflow earns the name "complex," it's almost always organized into groups - a green box around the upscale chain, a red box around the refiner, a blue box you labeled "don't touch." The AUN Group Controller is the node that finally puts a dashboard on those boxes. Point it at a group name, and one toggle bypasses, mutes, collapses, or does any combination - for the entire group, no matter how many nodes are inside.

How it works

It's a graph-state controller: pick a mode (Bypass, Mute, Collapse, or Bypass+Collapse / Mute+Collapse), give each slot a group name, and the node pushes state changes to the ComfyUI frontend before the run starts. Group matching is partial, and it supports exclusions - put !load in the slot and everything in the group except nodes matching "load" gets hit. That exclusion syntax (also -load) is the same convention AUN uses across its controllers, so it's worth learning once.

The killer feature is use_all_groups. Flip it on and the node scans the workflow, lists every group it finds, and gives you a toggle for each one automatically - no typing names. For a one-off tidy-up that's the fastest way to mute a section you're not using this batch without deleting anything. Turn it off and you're back to manual slots, which is the better long-term setup because slot positions survive workflow edits.

Slot-level toggles show the AUN convention: 🟢 active, 🔴 controlled by mode. There's an AllSwitch ("All 🟢" vs "Individual") to force every listed group active in one click, a toggle_restriction for the familiar max one / always one / iterate / random behaviors, and a control_mode that switches the whole node to index-driven - wire the Index input and the slot matching that number activates, which is how you chain this to a randomizer for rotating group presets.

The few inputs that matter

• mode - the real choice. Bypass and Mute behave differently: bypass passes data through unchanged, mute stops the node running at all. For groups full of loaders and samplers, mute is usually what you want.
• group_name_N - target group(s) per slot; partial match, newline/comma/semicolon separated, !/- to exclude.
• use_all_groups - auto-populate from the graph. Try it first; it's the "wow" moment.

Outputs: Active Groups (STRING, the names actually active - handy for filenames or logging) plus Switch 1…Switch 20 BOOLEAN pins you can feed into other switches. show_outputs hides those pins if you want a clean canvas.

Gotchas

Group targeting depends on the group title matching - rename a group and a hardcoded slot silently stops matching (partial matching helps, but a totally new name won't hit). And if use_all_groups doesn't list something, the node hasn't seen the graph yet; a reload or re-run usually fixes it. Note it targets groups as ComfyUI knows them in the current prompt - it's a live controller, not a persistent setting.

Install

It's part of AUN ComfyUI Nodes (loz2754). Install once, get all of it:

cd ComfyUI/custom_nodes
git clone https://github.com/loz2754/AUN-ComfyUI-Nodes

or search "AUN ComfyUI Nodes" in ComfyUI Manager, then restart. The pack's deps (piexif, opencv-python-headless, imageio-ffmpeg, requests) install automatically with Manager; no model files involved. If your workflow is a loose pile of nodes instead of a tidy group collection, the same logic lives in AUN Node Controller (by node ID/title), and Multi Bypass/Mute Index covers pure index switching by ID.
