HAP - AWS Setup

Here you'll find the resources for setting up the AWS Services needed for managing the Home Alarm Project.

  1. Edit the *json files replacing the following parameters:
    • 01.sns-params.json:
      • SubscriptionEmail
        it's the email address you want to be subscribed to the SNS topic for notifications
    • 02.iot-params.json:
      • IoTCertName
        it's the THING certification name you should have from previous steps (see prerequirements )
    • 04.rest-api-params.json:
      • IOTSubdomain
        it's the IOT Subdomain. You can get it running the following command:

        aws iot describe-endpoint --endpoint-type iot:Data-ATS --output text | cut -d "-" -f 1

  2. Setup your preferred profile:

AWS_PROFILE=<MY_PROFILE>

  1. Create the SNS Stack:

aws --profile $AWS_PROFILE cloudformation create-stack --stack-name simple-home-alarm-resources-sns --template-body file://01.sns.yaml --parameters file://./01.sns-params.json

  1. Create the IOT Stack:

aws --profile $AWS_PROFILE cloudformation create-stack --stack-name simple-home-alarm-resources-iot --template-body file://02.iot.yaml --parameters file://./02.iot-params.json

  1. Setup Cognito user parameters:

USERNAME=<MY_USERNAME>

PASSWD=<MY_PASSW>

REGION=<MY_REGION>

  1. Create the Cognito Stack

aws --profile $AWS_PROFILE cloudformation create-stack --stack-name simple-home-alarm-resources-cognito --template-body file://03.cognito.yaml --parameters file://./03.cognito-params.json --capabilities CAPABILITY_NAMED_IAM

  1. Get back some useful parameters and create the AndroidApp User:

UPID=$(aws --profile $AWS_PROFILE cognito-idp list-user-pools --query "UserPools[?Name == 'simpleCognito-user-pool'].{Id:Id}" --max-results 10 --output text)

UPCID=$(aws --profile $AWS_PROFILE cognito-idp list-user-pool-clients --user-pool-id $UPID --query "UserPoolClients[?ClientName == 'simpleCognito-client'].{Id:ClientId}" --max-results 10 --output text)

IPID=$(aws --profile $AWS_PROFILE cognito-identity list-identity-pools --max-results 10 --query "IdentityPools[?IdentityPoolName == 'simpleCognito-identity-pool'].{Id:IdentityPoolId}" --output text)

aws --profile $AWS_PROFILE cognito-idp admin-create-user --user-pool-id $UPID --username $USERNAME --temporary-password "$PASSWD"

aws --profile $AWS_PROFILE cognito-idp admin-set-user-password --user-pool-id $UPID --username $USERNAME --password "$PASSWD" --permanent

aws cognito-idp initiate-auth --region $REGION --auth-flow USER_PASSWORD_AUTH --client-id $UPCID --auth-parameters USERNAME=$USERNAME,PASSWORD="$PASSWD"

  1. Create the API-Gateway Stack:

aws --profile $AWS_PROFILE cloudformation create-stack --stack-name simple-home-alarm-resources-restapi --template-body file://04.rest-api.yaml --parameters file://./04.rest-api-params.json --capabilities CAPABILITY_NAMED_IAM

  1. Create the empty dummy record into the DynamoDB Table

aws --profile $AWS_PROFILE dynamodb put-item \

--table-name simpleAlarmStatusTable \

--item \

'{"iotTopic": {"S":"esp32/pub"},"lastAlarmNotificationTmsMs":{"N":"1663512656619"}, "alarmStatus":{"S": ""}, "alarmMode":{"S": "OFF"},"sensors":{"L":[{"M":{"alarm":{"BOOL":false},"lastCheck":{"N":"0"},"deviceCode":{"S":"PROX_1"},"value":{"S":"0.0000"},"enabled":{"BOOL":false}}},{"M":{"alarm":{"BOOL":false},"lastCheck":{"N":"0"},"deviceCode":{"S":"PROX_2"},"value":{"S":"0.0000"},"enabled":{"BOOL":false}}},{"M":{"alarm":{"BOOL":false},"lastCheck":{"N":"0"},"deviceCode":{"S":"PROX_3"},"value":{"S":"0.0000"},"enabled":{"BOOL":false}}},{"M":{"alarm":{"BOOL":false},"lastCheck":{"N":"0"},"deviceCode":{"S":"PROX_4"},"value":{"S":"0.0000"},"enabled":{"BOOL":false}}},{"M":{"alarm":{"BOOL":false},"lastCheck":{"N":"0"},"deviceCode":{"S":"PROX_5"},"value":{"S":"0.0000"},"enabled":{"BOOL":false}}},{"M":{"alarm":{"BOOL":false},"lastCheck":{"N":"71"},"deviceCode":{"S":"PIR_1"},"value":{"S":"2099.9433"},"enabled":{"BOOL":true}}},{"M":{"alarm":{"BOOL":false},"lastCheck":{"N":"0"},"deviceCode":{"S":"PIR_2"},"value":{"S":"0.0000"},"enabled":{"BOOL":false}}},{"M":{"alarm":{"BOOL":false},"lastCheck":{"N":"0"},"deviceCode":{"S":"PIR_3"},"value":{"S":"0.0000"},"enabled":{"BOOL":false}}}]}, "lastUpdateTmsMs":{"N":"1663512656619"}}'

  1. Deploy the Lambda handler using Serverless framework:

sls deploy --aws-profile $AWS_PROFILE
