Connecting a Dash Button to IFTTT

README.md

Earlier in the week, I saw a Medium piece about using Dash buttons as a cheap connected device, and decided to play with it. I decided the most flexible solution was to wire it to IFTTT, so I did that.

He has instructions, but here’s what I did.

1. Create a virtualenv and install Scapy.
2. Then install Requests.
3. Follow the instructions on Medium to get the MAC address of your device.
4. Learn how to use the Maker channel and create a URL for this trigger.
5. Modify your dash-button.py file to match the one below and fill in the right information.
6. Create an IFTTT recipe and go to town.

dash-button.py

from scapy.all import *
import requests

def arp_display(pkt):
  if pkt[ARP].op == 1: #who-has (request)
    print "aye"
    if pkt[ARP].psrc == '0.0.0.0': # ARP Probe
      if pkt[ARP].hwsrc == '{MAC ADDRESS OF BUTTON}':
        r = requests.post("https://maker.ifttt.com/trigger/{event_name}/with/key/{secret_key}")
        print r

print sniff(prn=arp_display, filter="arp", store=0, count=30)

This is my result... <Sniffed: TCP:0 UDP:0 ICMP:0 Other:0>
