A LaMetric skill(?) to push DarkSky information to your alarm clock.


Configuration/set up

  • Sign up for Dark Sky API
  • Sign up for LaMetric as a developer
  • Create an app. Specify a basic thing for it to display (like a weather icon and "Hello" text). The content to display is pushed by the code when it updates, so you don't need to worry about including enough cards or anything.
  • Create (or already have) an S3 bucket which will store the code package during deployment. Doesn't need to be public.
  • Install jq and sam-local

Create params.json as a standard CloudFormation parameters JSON file.

Specify the following keys:

  • DarkskyApiKey: your Dark Sky API key
  • Latitude: the latitude to fetch weather for
  • Longitude: the longitude
  • LaMetricToken: your API token for LaMetric
  • LaMetricKey: your app key for LaMetric


Something like:

pip3 install -r requirements.txt in the darksky directory.

In the sam-app directory, sam package --template-file template.yaml --s3-bucket YOUR_S3_BUCKET --output-template-file output.yaml

This pushes the code up to S3 for the deployment to pick up later, and outputs the template for CloudFormation to use.


aws cloudformation deploy --template-file output.yaml --stack-name darksky-function --capabilities CAPABILITY_IAM --parameter-overrides $(jq -r '.[] | [.ParameterKey, .ParameterValue] | join("=")' params.json)

Note that deploy doesn't take a params file parameter so we have to fudge it with jq.

Every 30 mins (0/30 mins past the hour) the code will run and update your LaMetric. It doesn't run overnight. Modify the cron(...) property in the CloudFormation template to adjust.

You can’t perform that action at this time.
