How I Hacked Amazon’s $5 WiFi Button to track Baby Data
Ted Benson

Ted, its awesome to see the write up. I’ve been using dnsmasq on a router running TomatoUSB (similar to DD-WRT) to just reroute the traffic to a Raspberry Pi that toggles a light (a la except using these — $5 wifi/radio light switches, basically.

However, the dnsmasq approach is slow — clicking the dash takes 5–7 seconds to reach the pi. What sort of speed does your approach have? Would the ARP approach save much time? In theory I should be able to build some ESP8266 buttons (a la which should be about the same cost (in $, not in time) and get the time down to 2 sec or so, but I like the idea of repurposing the Dash Buttons.

Lastly, It’s still pretty new and doesn’t seem to be widely known about yet, but it really does utterly open up what one can do with these.
