Create IoT architecture diagrams using PlantUML syntax with device and sensor stencil icons. Best for smart home, industrial IoT (IIoT), fleet management, edge…
IoT Architecture Diagram Generator
Quick Start: Select device/sensor icons → Place edge gateways → Connect to cloud services → Group into zones → Wrap in ```plantuml fence.
⚠️ IMPORTANT: Always use ```plantuml or ```puml code fence. NEVER use ```text — it will NOT render as a diagram.
Critical Rules
Every diagram starts with @startuml and ends with @enduml
Use left to right direction for typical IoT data flows (Device → Edge → Cloud)
Use mxgraph.aws4.* stencil syntax for IoT service and device icons
Default colors are applied automatically — you do NOT need to specify fillColor or strokeColor
Use rectangle "Zone" { ... } or package "Site" { ... } for grouping
Directed flows use -->, async/event-driven flows use ..> (dashed)
Full stencil reference: See stencils/README.md for 9500+ available icons.
