This project is quite simple: Whenever the Dash button configured in environment variables is pressed, play or pause is sent to Amazon via a REST service, and whatever you were listening to last restarts, or pauses.
You're going to need some information to get this running.
- A login cookie from alexa.amazon.com in the variable
COOKIE - Your device ID in the variable
DEVICE - Your device serial in the variable
SERIAL - The MAC address of your Dash button in the variable
MAC - The CSFR token in the variable
CSFR
If in doubt, just put those variables in the start.sh script, and use that to launch the server.
The first three should be easy to find. Install Postman for Chrome, go to Amazon's Alexa SPA, login and capture a few commands with Postman. (You might need the standalone version of Postman to capture the cookie, but there are other ways of getting that cookie. Google it.)
The MAC address of your Dash is a little more complicated, but (https://medium.com/@edwardbenson/how-i-hacked-amazon-s-5-wifi-button-to-track-baby-data-794214b0bdd8#.y2pjafhf2)[this article] by (https://medium.com/@edwardbenson)[Ted Benson] should be enough to get you started.
You might need to run the script as root in order to get the privileges necessary to intercept ARP probes. Fair warning: this is dumb, and the reason I want to run the server in Docker ASAP!
The Dockerfile does not currently work. It runs the script, but does not detect any ARP probes. This is probably not a networking issue, but rather an issue with the library I’m using to detect them. I will try switching to Scapy when I get the chance.
