# 使用 的 AWS IoT Core 規則引擎 AWS IoT Events
<a name="iotevents-commented-examples-iot-rules-examples"></a>

下列規則會將 AWS IoT Core MQTT 訊息重新發佈為影子更新請求訊息。我們假設為由偵測器模型控制的每個區域定義了供暖單位和冷卻單位的 AWS IoT Core 物件。在此範例中，我們定義了名為 `"Area51HeatingUnit"`和 的物件`"Area51CoolingUnit"`。

CLI 命令：

```
aws iot create-topic-rule --cli-input-json file://ADMShadowCoolOffRule.json
```

檔案： `ADMShadowCoolOffRule.json`

```
{
  "ruleName": "ADMShadowCoolOff",
  "topicRulePayload": {
    "sql": "SELECT topic(3) as state.desired.command FROM 'hvac/Cooling/Off'",
    "description": "areaDetectorModel mqtt topic publish to cooling unit shadow request",
    "ruleDisabled": false,
    "awsIotSqlVersion": "2016-03-23",
    "actions": [
      {
