Skills iot

Create IoT architecture diagrams using PlantUML syntax with device and sensor stencil icons. Best for smart home, industrial IoT (IIoT), fleet management, edge computing, and sensor network layouts.

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"  { ... }

package "Site" { ... }

for grouping

Directed flows use
```
-->
```
, async/event-driven flows use
```
..>
```
(dashed)

Full stencil reference: See stencils/README.md for 9500+ available icons.

Connection Types

Syntax	Meaning	Use Case
`A --> B`	Solid arrow	Sync API / data flow
`A ..> B`	Dashed arrow	Async telemetry / MQTT publish
`A -- B`	Solid line	Physical / bidirectional link
`A --> B : "label"`	Labeled connection	Describe protocol or data

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
