A simple utility daemon for monitoring dash buttons on a local network and calling webhooks associated with them. Press button, call URL. Easy. This was written originally to create a poo button, which then got written up in Wired.

Get the code from GitHub and install dependencies. You'll need a recent version of nodejs installed. You'll also need to install libpcap on your system.

brew install libpcap # For OSX, your system may vary
git clone https://github.com/Floppy/dashmonitor.git
cd dashmonitor
npm install

curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install nodejs libpcap-dev
git clone https://github.com/Floppy/dashmonitor.git
cd dashmonitor/
npm install

sudo node_modules/node-dash-button/bin/findbutton

Press the button, and the MAC address will appear in the list.

cp config.json.example config.json
nano config.json

Create a line for each dash button, with the MAC address from the previous step and the webhook URL you want to call. You can use requestb.in if you're just testing, otherwise hooking up to a Zapier webhook is a good approach to then configure other services.

npm start

You can run this anywhere, but if you're using OSX, there is a plist file for running it as a system daemon. First, edit dashmonitor.plist and set the paths in the ProgramArguments and WorkingDirectory keys correctly for your system. Then:

cp dashmonitor.plist /Library/LaunchDaemons
sudo launchctl load /Library/LaunchDaemons/dashmonitor.plist

If you have problems with the system daemon, I highly recommend debugging it with LaunchControl.

There is a systemd startup script for Raspbian or other Debian-ish systems:

sudo cp boot-scripts/systemd/dashbuton.service /etc/systemd/system/
sudo systemctl enable dashbutton.service
sudo start dashbutton.service

dashmonitor should now kick-off at boot-time
