Hello, I’ve recently built an Amazon Dash doorbell, which is basically an Tide Amazon dash which I connected to my home WIFI… I have a Pogoplug running Debian Linux, and I used an ARP probe python script which I placed in my cron jobs (it just run in a loop waiting for the Dash to connect to the WIFI) like this script:

from scapy.all import *

def arp_display(pkt):
if pkt[ARP].op == 1: #who-has (request)
if pkt[ARP].psrc == ‘0.0.0.0’: # ARP Probe
print “ARP Probe from: ” + pkt[ARP].hwsrc

print sniff(prn=arp_display, filter=”arp”, store=0, count=10)

once the Dash is pressed, it connects to the WIFI and disconnects, of which my Pogoplug detects the MAC address and executes a bash script… The Bash script basically just emails a screen grab from my CCTV using RTSP, sends the JPG to Flickr, and posts it to my facebook page… I also attached a USB speaker to my Pogoplug, and it then plays a WAV file (DING-DONG.WAV) which notifies people at home that there is someone at the door…

I planned on using a bluetooth button instead as the Dash is limited to 1000 presses before it dies and the battery is hardwired…

I was thinking that all I need is to figure out the button press from Bluetooth, but as you say, the bluetooth button goes to sleep mode, and wakes up on first press?
