Requirements for alarm notifications in AWS IoT SiteWise
AWS IoT Events uses an AWS Lambda function in your AWS account to send alarm notifications. You must create this Lambda function in the same AWS Region as your alarms to enable alarm notifications. This Lambda function uses Amazon Simple Notification Service (Amazon SNS) to send text notifications and Amazon Simple Email Service (Amazon SES) to send email notifications. When you create the AWS IoT Events alarm, you configure the protocols and settings that the alarm uses to send notifications.
Note

AWS IoT Events provides an AWS CloudFormation stack template that you can use to create this Lambda function in your account. For more information, see Alarm notification Lambda function in the AWS IoT Events Developer Guide.
