IoT

AWS IoT lets you invoke a Lambda function in response to messages published to the AWS IoT message broker. osls creates an IoT topic rule whose SQL statement selects matching MQTT messages and invokes your function. See the AWS IoT documentation.

Simple event definition

This will enable your Lambda function to be called by an AWS IoT rule.

functions:
  myIoT:
    handler: myIoT.handler
    events:
      - iot:
          sql: "SELECT * FROM 'some_topic'"

Enabling / Disabling

Note: iot events are enabled by default.

This will create and attach a disabled iot event for the myIoT function.

functions:
  myIoT:
    handler: myIoT.handler
    events:
      - iot:
          sql: "SELECT * FROM 'some_topic'"
          enabled: false

Specify Name and Description

Name and Description can be specified with the help of the name and description properties.

functions:
  myIoT:
    handler: myIoT.handler
    events:
      - iot:
          name: 'myIotEvent'
          sql: "SELECT * FROM 'some_topic'"
          description: 'My IoT Event Description'

Specify SQL Versions

SQL Versions can be specified for an iot event. However the sqlVersion is not a required property.

functions:
  myIoT:
    handler: myIoT.handler
    events:
      - iot:
          sql: "SELECT * FROM 'some_topic'"
          sqlVersion: 'beta'
