Inspiration

Alexa struggles to send requests across varies networks and on its own local network without dedicated hardware.

What it does

Talk to Alexa, this the communicates with AWS and sends a HTTP request to a node.js server (Also on AWS), This request then updates a server side variable which can then be read by a raspberry pi in order to change it GPIO from any internet connected network.

How I built it

I started with learning to program a basic Alexa skill. I then attempted to allow Alexa to communicate directly with Raspberry Pi on local network (Alexa doesn’t like doing this). I then created a node.js server on AWS which could route requests from Alexa to the Raspberry Pi. I enabled Alexa to send HTTP requests to the node.js server. The raspberry Pi was then programmed to use a GET request to get data from the server. I then built a basic circuit to demonstrate the functionality

Challenges I ran into

Alexa doesn’t like to communicate locally, instead Alexa likes to run all commands as if external (running from AWS). Accessing a raspberry Pi from the internet on the university network isn’t possible so I created a node.js server hosted at AWS to allow me to get information from Alexa.

Accomplishments that I'm proud of

Getting Alexa to send a HTTP request

What I learned

Alexa isn’t very good for debugging.

What's next for AlexaIO

Size down and increase functionality.
