AWS SAM (lambda) function to scrape real time glucose values from dexcom every 5 minutes.

This aws lambda function impersonates a share app, and asks for the most recent blood glucose value.

Yes! There is! Check it out here: http://www.nightscout.info/
The reason I decided to make this was for a couple reasons:

• Fun aws lambda project
• data goes in dynamo instead of mlab, which is what nightscout uses
• app is serverless, so may be cheaper than running the full nightscout app on heroku.

• 1 AWS Python Lambda Function
• 1 Dynamo DB Table

• Navigate to the cron foler, there you should see a file called app.py. That is where the logic lies.

• AWS Acct
• AWS CLI installed
• AWS SAM CLI
• Note: If you run aws --version from your terminal, your executable versions should be at least at these versions: aws-cli/1.16.161 Python/3.7.3 Darwin/18.5.0 botocore/1.12.151

• make sure your aws credentials are set up, you can type aws configure to ensure this.
• git clone https://github.com/dddiaz/dexcom-lambda.git
• navigate to the root dir
• create a s3 bucket to put your code into:

aws s3 mb s3://dev-dexcom-lambda

• Package and deploy: (Make sure you update your dexcom user name and password)

aws cloudformation package --template-file /Users/danieldiaz/github/dexcom-lambda/.aws-sam/build/template.yaml --s3-bucket dev-dexcom-lambda --output-template-file packaged.yaml
 aws cloudformation deploy --template-file /Users/danieldiaz/github/dexcom-lambda/packaged.yaml --stack-name dev-dexcom-lambda --parameter-overrides DEXCOM_ACCOUNT_NAME=<YOUR-DEXCOM-USERNAME-HERE> DEXCOM_PASSWORD=<YOUR-DEXCOM-PASSWORD-HERE>

• Done!
• Navigate to your lambda console to see it executing, or go to the dynamodb table Glucose, to check out the data.

• make sure you have the aws extension,
• clone the project, right click on the template,
• click deploy serverless template,
• update the two parameters for dexcom username and password,
• then Done!

• python
• aws lambda
• aws DynamoDB
• Eventually switch to aws timetream?

• Add License?
• Add launchstack url?
• lower read write capacity units for dynamodb
