# node-red-contrib-automatanexus-hvac-vibration

Professional Industrial Vibration Monitoring for Node-RED by AutomataNexus AI

## Overview

This Node-RED node provides professional-grade parsing and analysis of WitMotion WTVB01-485 vibration sensor data for industrial equipment monitoring. It supports ISO 10816-3 compliance and handles multiple equipment types including cooling towers, pumps, compressors, and more.

## Features

- **ISO 10816-3 Compliant**: Automatic vibration severity classification based on equipment type and power rating
- **Multi-Format Support**: Parses console output, JSON API data, and legacy formats
- **Equipment-Based Configuration**: Define custom settings for each piece of equipment
- **Smart Equipment Detection**: Automatically detects equipment type from naming conventions (v2.1.0+)
- **Real-time Alerts**: Generate warnings and critical alerts based on ISO standards
- **Global Variables**: Optional Node-RED global variable integration for dashboard compatibility
- **Maintenance Predictions**: Estimated remaining useful life based on vibration trends

## What's New in v2.2.0

- Direct integration with multi-port monitoring system API
- Parser trusts monitoring system's configuration instead of overriding it
- Automatic detection of monitoring API JSON format
- Equipment configuration from API is preserved (HP, voltage, phase)

## What's New in v2.1.0

- Support for equipment name-based identification (e.g., "Cooling_Tower_1")
- Auto-detection of equipment type from equipment names
- Better handling of new multi-port monitor output format
- Improved parsing for both sensor addresses and equipment names

## Installation

```bash
npm install node-red-contrib-automatanexus-hvac-vibration
```

Or install directly from Node-RED's palette manager.

## Configuration

### Node Properties

- **Output Format**: Standard (full industrial data structure)
- **Global Variables**: Enable/disable global variable setting
- **Global Prefix**: Prefix for global variable names (default: "industrial")
- **Sensor Mappings**: Configure equipment details for each sensor

### Sensor Mapping Configuration

Each sensor can be configured with:
- **Address**: Sensor address (hex or decimal)
- **Name**: Equipment name (e.g., "Cooling_Tower_1")
- **Type**: Equipment type from supported list
- **Location**: Physical location
- **Power (HP)**: Motor horsepower
- **Foundation Type**: rigid or flexible
- **RPM**: Nominal operating RPM
- **Custom Zones**: Override ISO zones if needed

}
```

## ISO 10816-3 Classifications

The node automatically determines ISO class based on:
- Equipment power rating (HP/kW)
- Foundation type (rigid/flexible)
- Equipment type specific requirements

### Vibration Zones:
- **Zone A**: Good condition (newly commissioned)
- **Zone B**: Acceptable for long-term operation
- **Zone C**: Unsatisfactory for long-term operation
- **Zone D**: Vibration levels likely to cause damage

## Global Variables

When enabled, sets variables like:
- `industrial_cooling_tower_1_temperature_f`
- `industrial_cooling_tower_1_vibration_velocity`
- `industrial_cooling_tower_1_iso_zone`
- `industrial_cooling_tower_1_condition`
- `industrial_cooling_tower_1_alerts`

## Example Flow

Import the test flow from the package:
```bash
