Alfred – Virtual Butler

An alexa app that knows where you put stuff using Amazon echo, web server, and bluetooth beacons

 

Have you ever stayed in an airbnb room, a hotel, or even crashing to a friend’s place and found yourself knowing nothing about where things are? Well now, with an echo and a bunch of bluetooth beacons you could label every corner of your house and let our AI, Alfred, tells you or your guests where things are when you need it

 

Bluetooth beacons have NFC that points to a web app. By tapping your phone to the beacon, a webpage will pop up where you can give label to each beacons. And whoever needs to know where, say the spoons are, you could just ask Alfred through echo and it will point you to the respective beacon

 

We programmed each of the bluetooth beacon to beam URL through NFC, so any phone that taps it could be taken to the website. We have a dedicated nodejs server running in Salesforce’s Heroku that handles APIs and talks to a mongodb database hosted in MongoDB Atlas. We also have an Amazon Alexa app deployed in AWS Lambda that handles the natural language processing that acts as a voice interface
