Node State Controller

Sometimes you don't want a 20-slot control panel. You want to say "collapse this refiner and mute it," once, and move on. Node State Controller is the AUN pack's single-target version of that: one node, no outputs, that sets bypass/mute and collapse state for nodes addressed by ID, by group title, or by a list of titles. Think of it as the manual override the big controllers don't give you - it's a light switch, not a smart-home app.

How it works

You pick a target_mode (Node IDs, Group Title, or Node Titles), fill in the matching field, and the node pushes the state to ComfyUI's frontend via PromptServer events when it executes - no data flows through it, which is why it has zero outputs and you wire it into nothing. It's a state setter, not a data node; you drop it anywhere in the graph and it does its job on run.

The useful part is the interaction between combined, use_mute, collapse, and active:

• combined ON - collapse and disable in one action, so active is ignored. The "I'm done with this branch" button.
• combined OFF - collapse and active are independent. collapse hides/shows the body; active enables the nodes or bypasses/mutes them (depending on use_mute).

When use_mute is ON it mutes; otherwise it bypasses. The node even cleans up after itself by resetting the other state - if you mute a node it also clears any stale bypass so the two don't fight.

Targeting options

• Node IDs - comma-separated, e.g. 5,12,23. Fastest for a handful of specific nodes, but fragile if the graph is edited (IDs shift).
• Group Title - the whole group, with optional group_exclude_titles to exempt specific node titles inside it. Partial matching supported.
• Node Titles - newline/comma/semicolon separated titles; !/- prefixes exclude. This is the friendliest option because titles survive most edits.

When to reach for it

• One-off cleanup - mute + collapse a branch you're testing without deleting it.
• As a "condition" gate - wire a boolean into active from a controller or switch node, and the state becomes conditional: a node set that's only disabled when some other node says so.
• Inside a shared workflow - a single explicit state setter is easier for someone else to read than six hidden bypasses.

It's strictly less flexible than AUN Node Controller (no labels, no boolean outputs, no per-slot logic) - but that's the point. When you need "this one thing, off," the 20-slot panel is overkill and this is faster to set up.

Install

Standard AUN install: ComfyUI Manager, search "AUN ComfyUI Nodes", or

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

then restart. Pack dependencies (piexif, opencv-python-headless, imageio-ffmpeg, requests) install via Manager or pip install -r custom_nodes/AUN-ComfyUI-Nodes/requirements.txt. No model files.

The caveat

Since it's a setter that fires on execution, it doesn't persist through a graph reload the way a widget state does - if you expect "I set it once, it stays," you'll want the state baked into the workflow by the controller nodes' widgets instead. And like every graph-state node, it targets what's in the current graph, so a mismatched title or stale ID just does nothing silently. Check your spelling, run once, and confirm in the UI before trusting it.
