node-red-contrib-msg-repeater

A Node-RED node that can capture and repeat messages.

Features

• Capture any message flowing through the node
• Replay the captured message on demand
• Visual status indicator showing capture state
• Button on the node to trigger capture mode

Installation

Local Installation

cd ~/.node-red
npm install /path/to/node-red-contrib-msg-repeater

From NPM (Once Published)

cd ~/.node-red
npm install node-red-contrib-msg-repeater

Usage

The node has two modes of operation:

1. Normal mode: All messages pass through unchanged.
2. Capture mode: When a message with msg.capture = true is received, the node enters capture mode. The next message will be stored for later replay and also passed through unchanged.

To replay a captured message, send a message with msg.repeat = true.

UI Buttons

• The main button on the node triggers capture mode
• The "Repeat" button in the configuration panel triggers a replay of the captured message

Status Indicators

• No status: Normal mode, no message captured
• Blue dot "Capturing": Node is in capture mode, waiting for next message
• Green dot "Captured": A message has been captured and is available for replay
