Check out Ted Benson’s great Amazon Dash hack to use the device for logging baby activity to a spreadsheet. Ted investigated how the Dash works and found he can detect button presses by watching for the Dash to turn on and join his WiFi network. This is a clever hack since the Dash doesn’t need to be taken apart and reprogrammed, instead a script running on a computer watches for the Dash to join the network before it takes action. The post goes into a lot of great detail about how to use Scapy to detect network traffic from the Dash and Magic Form to update the spreadsheet. Awesome hack!
