node-red-bytes-to-float-converter

A Node-RED custom node that converts raw byte data into IEEE-754 32-bit floating-point values.
Ideal for PLCs, Modbus, industrial sensors, and binary protocol decoding.

Features

• Converts Bytes → Words → Longs → IEEE-754 Floats
• Supports Big Endian (BE) and Little Endian (LE)
  • Configurable byte order
  • Configurable word order
• Configurable decimal precision
• Accepts input as:
  • Array<number> (0–255)
  • Buffer
• Runtime overrides via msg properties
• Input validation with warnings
• Live node status for debugging

Installation

Copy the node into your Node-RED custom nodes directory (or add it to your Node-RED package): Copy this node into your Node-RED custom nodes directory or install it as part of your Node-RED package.

Typical custom node location:

~/.node-red/nodes/

After adding the node, restart Node-RED.
