Input definitions for an HVAC system in Amazon IoT Events

A seedTemperatureInput is used to create a detector instance for an area and define its operational parameters.

Configuring inputs for HVAC systems in Amazon IoT Events is important for effective climate control. This example shows how to set up inputs that capture parameters such as, temperature, humidity, occupancy, and energy consumption data. Learn to define input attributes, configure data sources, and set up preprocessing rules to help your detector models receive accurate and timely information for optimal management and efficiency.

CLI command used:

aws iotevents create-input --cli-input-json file://seedInput.json

File: seedInput.json

{
  "inputName": "seedTemperatureInput",
  "inputDescription": "Temperature seed values.",
  "inputDefinition": {
    "attributes": [
      { "jsonPath": "areaId" },
      { "jsonPath": "desiredTemperature" },
      { "jsonPath": "allowedError" },
      { "jsonPath": "rangeHigh" },
      { "jsonPath": "rangeLow" },
      { "jsonPath": "anomalousHigh" },
      { "jsonPath": "anomalousLow" },
      { "jsonPath": "sensorCount" },
      { "jsonPath": "noDelay" }
    ]
  }
}

Response:

{
    "inputConfiguration": {
        "status": "ACTIVE", 
        "inputArn": "arn:aws:iotevents:us-west-2:123456789012:input/seedTemperatureInput", 
        "lastUpdateTime": 1557519620.736,

        "inputName": "seedTemperatureInput", 
        "inputDescription": "Temperature seed values."
    }
}

A temperatureInput should be sent by each sensor in each area, as necessary.
