WMATA NextBus Predictor for Amazon's Echo

Branch Build Status
Master Build Status
Develop Build Status

This app provides real-time bus arrival information on a Amazon's Echo, using WMATA's public API.

It is intended to be deployed as a Lambda function on AWS and uses DynamoDB to store users' home stop ID, based on their Amazon Echo user ID.

Before the initial "Get stop" request is made, a home stop ID must be set, using the SetHomeIntent intent.

Note that you will need the following environment variables to be set for the app to function:

Variable Purpose
WMATA_API_KEY Your developer's API key from https://developer.wmata.com/
ALEXA_APP_ID The ID of your Alexa application. This is found at https://developer.amazon.com/

If you save these env vars in your Lambda config, I highly recommend that you use KMS to encrypt them, as they are both potentially sensitive pieces of information.

Disclaimer: This is an independently developed app and is in no way, shape or form connected to, affiliated with, or maintained by the Washington Metropolitan Area Transit Authority
