| description | Create IoT architecture diagrams using PlantUML syntax with device/sensor stencil icons. Best for smart home, industrial IoT (IIoT), fleet management, edge computing, and sensor network diagrams. NOT for general cloud infra (use cloud skill) or simple flowcharts (use mermaid). |

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.

Quick Example
@startuml
left to right direction
rectangle "Factory Floor" {
mxgraph.aws4.sensor "Temp\nSensor" as s1
mxgraph.aws4.iot_thing_plc "PLC" as plc
}
mxgraph.aws4.greengrass "Greengrass\nEdge" as gg
mxgraph.aws4.iot_core "IoT Core" as core
mxgraph.aws4.iot_analytics "IoT\nAnalytics" as analytics
s1 --> gg : MQTT
plc --> gg
gg --> core
core --> analytics
@enduml
