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
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
Webhook Trigger Node
HTTP Request Node
{ "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
Common Workflows AI-Powered Security Alerts Rhombus Webhook (Camera Alert) ↓ Extract Event Data ↓ OpenAI Agent (Analyze severity) ↓ IF High Priority ├─→ Create PagerDuty Incident ├─→ Send SMS via Twilio └─→ Create Video Clip ELSE └─→ Log to Database
Nodes Used : Webhook, Code, OpenAI, HTTP Request (Rhombus), PagerDuty, Twilio, PostgreSQLAutomated Access Management Google Sheets (Employee List) ↓ Schedule Trigger (Daily 6 AM) ↓ Loop Through Rows ↓ HTTP Request → Rhombus API ├─→ Add to Access Group └─→ Assign Credential ↓ Update Sheet with Status
Nodes Used : Schedule, Google Sheets, HTTP Request (Rhombus), CodeIntelligent Video Archival Rhombus Webhook (New Clip) ↓ Get Clip Details (HTTP Request) ↓ AI Vision Analysis (OpenAI GPT-4V) ↓ Extract Metadata & Tags ↓ Store in S3 + Metadata to Database ↓ Update Search Index
Nodes Used : Webhook, HTTP Request (Rhombus), OpenAI, AWS S3, PostgreSQL, ElasticsearchHTTP Request Examples Get Camera List HTTP Request Node
Code Node (Process Response)
{ "method" : "POST" , "url" : "https://api2.rhombussystems.com/api/camera/getMinimalCameraStateList" , "authentication" : "predefinedCredentialType" , "sendHeaders" : true , "headerParameters" : { "parameters" : [ { "name" : "x-auth-apikey" , "value" : "={{$credentials.rhombusApiKey}}" } ] } }
Create Video Clip { "method" : "POST" , "url" : "https://api2.rhombussystems.com/api/camera/createClip" , "sendBody" : true , "bodyParameters" : { "parameters" : [ { "name" : "cameraUuid" , "value" : "={{$json.cameraUuid}}" }, { "name" : "startTime" , "value" : "={{$json.startTime}}" }, { "name" : "durationSecs" , "value" : "30" }, { "name" : "title" , "value" : "AI-Detected Incident" } ] } }
Stream Live Video { "method" : "POST" , "url" : "https://api2.rhombussystems.com/api/camera/createSharedLiveVideoStream" , "bodyParameters" : { "parameters" : [ { "name" : "cameraUuid" , "value" : "={{$json.cameraUuid}}" }, { "name" : "name" , "value" : "Security Monitor Stream" }, { "name" : "expiresAt" , "value" : "={{DateTime.now().plus({hours: 24}).toISO()}}" } ] } }
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 ├─→ Create Incident └─→ Alert Security Team
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-apikeyValue : 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”

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 };
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
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 }
See n8n custom nodes documentation for full implementation.
