ComfyUI Wireless Link (Simple)

Wireless data transfer between nodes — no visible wires. Inspired by Blackmagic Fusion's Wireless Link.

What It Does

Two nodes. Send stores any data to a named channel. Get retrieves it. No wires needed between them.

Works with every ComfyUI data type: IMAGE, MODEL, LATENT, VAE, CLIP, CONDITIONING, STRING, INT, FLOAT — anything.

Nodes

Wireless Send

Input	Type	Description
value	ANY	Data to send (connect any output here)
channel	STRING	Channel name (case-sensitive)

Output	Type	Description
passthrough	ANY	Same data, passed through for execution order

Wireless Get

Input	Type	Description
channel	STRING	Channel name to retrieve from

Output	Type	Description
value	ANY	Data from the matching Send node

Usage

Basic: Image Transfer

[Load Image] -> [Wireless Send] -> [Preview Image]
                  channel: "photo"   (passthrough)

... elsewhere in workflow ...

[Wireless Get] -> [Save Image]
  channel: "photo"

Model Sharing

[Load Checkpoint]
   MODEL -> [Send: "model"] -> [Preview]
   CLIP  -> [Send: "clip"]  -> [Preview]
   VAE   -> [Send: "vae"]   -> [Preview]

... elsewhere ...

[Get: "model"] -> [KSampler]
[Get: "clip"]  -> [CLIP Text Encode]
[Get: "vae"]   -> [VAE Decode]

One Send, Many Gets

[Send: "base_image"] -> [Preview]

[Get: "base_image"] -> [Process A]
[Get: "base_image"] -> [Process B]
[Get: "base_image"] -> [Process C]

Important

Connect the passthrough. The Send node's passthrough output should be connected to a downstream node (Preview, Save, another node). This guarantees Send executes before Get. Without it, Send still runs (it's marked as an output node) but execution order isn't guaranteed.

Channel names are case-sensitive. "MyImage" and "myimage" are different channels.

Data persists in memory during a ComfyUI session. Restarting ComfyUI clears all channels. Stale data from previous runs is detected and warned about in the console.

Installation

cd ComfyUI/custom_nodes/
git clone https://github.com/jeremieLouvaert/comfyui-wireless-link-simple.git

Restart ComfyUI. Nodes appear under the wireless category.

No additional dependencies required.

Troubleshooting

"Channel not found" error — The Send node didn't execute before Get. Connect the Send node's passthrough output to any downstream node.

Stale data warning in console — A channel contains data from a previous execution. Check that the Send node is still in your workflow and connected.
