At home, I have several Amazon Dash Buttons throughout the house with a Raspberry Pi listening for clicks. I mainly use these buttons to track whether I have completed a specific task near the Amazon dash button. For example, I have have a button in my bathroom I click when I have flossed my teeth at night. Clicking this button would then mark the corresponding daily task completed.
Below is the script I use to mark a task done (some details omitted).
from scapy.all import *
import requests
# it takes a minute for the scapy sniffing to initialize, so I print this to know when it's actually ready to go
print('Init done.')
USER_ID = ""
API_TOKEN = ""
mac_address_to_task_data = {
"40:b1:cd:24:e2:1d": ("task_id", "task_name"),
"18:74:fd:eb:82:17": ("task_id", "task_name"),
"38:f7:3d:ca:32:dd": ("task_id", "task_name")
}
def execute_task(task):
url = "https://task-management-app.com/tasks/%s/%s" % (task[0], "up")
headers = {
"x-api-user": USER_ID,
"x-api-key": API_TOKEN,
}
requests.post(url, headers=headers)
print "Executed '%s'" % task[1]
def detect_button(pkt):
if pkt.haslayer(DHCP):
if pkt[Ether].src in mac_address_to_task:
task_data = mac_address_to_task.get(pkt[Ether].src)
execute_task(task)
else:
print "Unknown: " + pkt[Ether].src
sniff(prn=detect_button, filter="(udp and (port 67 or 68))", store=0)
