An small amazon dash golang program to send web requests on button press.
The program itself works well, but the Dockerfile and build for Raspberry Pi is a work in progress.
You should be able to compile it like this:
git clone https://github.com/chrisgilbert/godash/
cd godash/godash
go get github.com/google/gopacket
go build
You can then do mv conf-example.json conf.json and edit that file to add the appropriate details.
I haven't provided a program to do this, but this will help (an example on Mac, it's probably eth0 on Linux):
tcpdump -i en0 -e | grep who-has
This will show some arp traffic for anything requesting an IP mac translation from the switch/router.
You should be able to figure out what address is attached to the button fairly easily. (Mine starts with ac:)
I've only tested on Go 1.7.1.
