Integrate with N8N - Rhombus Developer Documentation

Self-hostable, open-source workflow automation with advanced AI capabilities. Integrate Rhombus using webhooks and HTTP nodes for custom automation workflows.

n8n doesn’t have a native Rhombus connector. Use Webhook and HTTP Request nodes to integrate with Rhombus API.

Why n8n for Rhombus

Feature	Benefit for Developers
Self-Hostable	Deploy on your infrastructure; full data control
Open Source	Fork, modify, extend; inspect all code
AI Agents	Build intelligent workflows with LLMs (OpenAI, Anthropic, etc.)
Code Nodes	Write JavaScript/Python directly in workflows
400+ Integrations	Connect Rhombus to databases, cloud services, business apps
No Rate Limits	Self-hosted = unlimited executions

Quick Start

Deploy n8n

Self-host via Docker or use n8n Cloud: docker run -it --rm --name n8n -p 5678:5678 n8nio/n8n

Get Rhombus API Key

Generate at Rhombus Console

Create Workflow

Add Webhook trigger → HTTP Request to Rhombus API → Process response

Integration Methods

Method 1: Webhook Trigger → Rhombus API

External Event → n8n Webhook → HTTP Request to Rhombus
Example: Form submission triggers door unlock

{
  "path": "rhombus-unlock",
  "method": "POST",
  "authentication": "headerAuth"
}

Method 2: Rhombus Webhook → n8n Processing

Rhombus Event → n8n Webhook → AI Processing → Actions
Example: Camera alert triggers AI analysis and notifications

Set Rhombus webhook URL to: https://your-n8n.com/webhook/rhombus-events

AI Agent Workflows

Conversational Security Assistant

Build chatbot that queries Rhombus data:

User Message → AI Agent
  ↓
Agent Tools:
  ├─→ Get Camera Status (HTTP → Rhombus)
  ├─→ List Recent Events (HTTP → Rhombus)
  ├─→ Create Video Clip (HTTP → Rhombus)
  └─→ Query Database
  ↓
AI Response with Actions

Use Case: Slack bot that answers “Show me camera feed from lobby” by creating live stream URL.

Anomaly Detection

Schedule (Every 15 min)
  ↓
Get Recent Door Events (HTTP → Rhombus)
  ↓
AI Agent (Analyze patterns)
  ↓
IF Anomaly Detected

Use Case: Detect unusual access patterns (e.g., door accessed 20 times in 5 minutes).

Credential Setup

Store Rhombus API Key

n8n Settings → Credentials → Add Credential
Choose “Header Auth”
Configure:
- Name: x-auth-apikey
- Value: Your Rhombus API key
Save as “Rhombus API”

Use in HTTP Nodes

Select credential in HTTP Request node → Authentication → Predefined Credential Type → Select “Rhombus API”

docker run -it --rm \
  --name n8n \
  -p 5678:5678 \
  -v ~/.n8n:/home/node/.n8n \
  n8nio/n8n

Access at http://localhost:5678

version: '3.8'
services:
  n8n:
    image: n8nio/n8n
    restart: always
    ports:
      - "5678:5678"
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=admin

    volumes:
      - ~/.n8n:/home/node/.n8n

npm install n8n -g
n8n start

Rhombus Webhook Configuration

Set Up in Rhombus Console

Go to Rhombus Console
Add webhook URL: https://your-n8n.com/webhook/rhombus-events
Select events to forward
Configure authentication if needed

Handle in n8n

Code Node (Parse Rhombus Webhook)

// Rhombus webhook payload
const event = $input.all()[0].json;

return {
  eventType: event.type,
  cameraUuid: event.camera?.uuid,
  timestamp: event.timestamp,
  severity: event.severity || 'medium',
  metadata: event.metadata
};

Performance Optimization

Strategy	Implementation
Batch API Calls	Use Loop node with delay between requests
Cache Responses	Store camera/door lists in n8n database
Rate Limiting	Add Wait node between Rhombus API calls (1000/hr limit)
Error Handling	Use Error Trigger to retry failed Rhombus API calls
Queue Processing	Use n8n queue mode for high-volume webhooks

Troubleshooting

Issue	Solution
Webhook not receiving	Check firewall; verify webhook URL in Rhombus Console; test with curl
API auth fails	Verify `x-auth-apikey` header set correctly; check key active in Console
Rate limit errors	Add delays between requests; cache data; use bulk endpoints
Timeout errors	Increase workflow timeout in n8n settings; optimize API calls
AI costs high	Cache AI responses; use smaller models for simple tasks; batch requests

n8n vs Other Platforms

Choose n8n When	Choose Zapier/Make When
Need self-hosting/data control	Want managed service
Building AI-powered workflows	Simple trigger-action patterns
Have development resources	Non-technical team
Want unlimited executions	Low volume automations
Need custom code in workflows	Visual-only workflows
Integrating with internal systems	Connecting SaaS apps only

Advanced: Custom Rhombus Node

For teams using n8n extensively, build a custom Rhombus node:

// Custom n8n node structure
export class Rhombus implements INodeType {
  description: INodeTypeDescription = {
    displayName: 'Rhombus',
    name: 'rhombus',
    icon: 'file:rhombus.svg',
    group: ['transform'],
    version: 1,
    description: 'Interact with Rhombus API',
    defaults: {
      name: 'Rhombus',
    },
    inputs: ['main'],
    outputs: ['main'],
    credentials: [
      {
        name: 'rhombusApi',
        required: true,
      },
    ],
    properties: [
      {
        displayName: 'Resource',
        name: 'resource',
        type: 'options',
        options: [
          { name: 'Camera', value: 'camera' },
          { name: 'Door', value: 'door' },
          { name: 'Clip', value: 'clip' },
        ],
        default: 'camera',
      },
      // ... operations and parameters
    ],
  };
  // ... execute method
}
