Alarm Logger w/ Email Notification

Postby danimal1228 » Tue Jan 21, 2014 3:22 pm

I wrote this because I do not have a PC running 24/7 in which to run the GUI. I wanted something that can run headless on a Raspberry Pi or any linux computer. Currently I have no need to communicate with the alarm via this program so it just logs information and sends out emails as needed. Eventually I will implement a web interface. You can set this up as a daemon to run in the background. It doesn't output anything to stdout, it just continuously appends logging information to the logfile and will send out emails for different events. Most cellular providers have a free email to sms gateway. For example, if you send an email to XXXXXXXXXX@txt.att.net, where you substitute your 10 digit phone number for the Xs, you will receive it as a text message.

I started with some of the examples that came with the software and just went from there. Many thanks to the developers for the source code and the forum. Feel free to use/modify/make suggestions. I pasted this code using the "code" tag but it might look funky. Does anyone have a better way to attach an in-line file?

Code: Select all
[size=85]
import time, logging, smtplib
from email.mime.text import MIMEText
from alarmdecoder import AlarmDecoder
from alarmdecoder.devices import SerialDevice

SERIAL_DEVICE = '/dev/ttyAMA0'      # Location of your AD2device
BAUDRATE = 115200         # Default Baud Rate
LOG_FILE = '/var/log/alarm.log'      # Make sure you have permission to write this file
EMAIL_USERNAME = 'user@server.com'   # Username to login to your SMTP server
EMAIL_PASSWORD = 'password'      # Password for your SMTP account
EMAIL_HOST = 'mail.pop.com'      # SMTP server
EMAIL_FROM = 'user@server.com'      # Your email address
EMAIL_TO = 'user@server.com'      # Destination email
SMS_TO = 'XXXXXXXXXX@txt.att.net'   # Email to SMS gateway address
EMAIL_SUBJECT = 'Alert from House Alarm!'

def main():
    try:
   # Set up logging of all INFO (or more) messages using specified format for timestamp

   logging.basicConfig(filename=LOG_FILE, level=logging.INFO, format='%(asctime)s %(message)s', datefmt='%m/%d/%Y %H:%M:%S')
   logging.info('---------- Starting log ----------')
   

   # Set up an event handler and open the device
   # I believe that AD2serial & AD2pi use a serial interface
   # and the AD2USB uses a USB interface
   
   device = AlarmDecoder(SerialDevice(interface=SERIAL_DEVICE))
   device.on_zone_fault += handle_zone_fault

      pStatus = 'Panel on Battery Power'

   logging.warning(pStatus)
   Send_Email(EMAIL_FROM, SMS_TO, EMAIL_SUBJECT, pStatus)

def handle_alarm(sender, status):
   if status:   #if alarm was just triggered
      aStatus = 'Alarm Triggered'
   else:      #if alarm was just cancelled
      aStatus = 'Alarm Cancelled'

   logging.warning(aStatus)
   Send_Email(EMAIL_FROM, SMS_TO, EMAIL_SUBJECT, aStatus)

def handle_low_battery(sender, status):
   logging.warning('Low Battery:'+str(status))
   Send_Email(EMAIL_FROM, EMAIL_TO, EMAIL_SUBJECT, 'Alarm-Low Battery')

I updated this script to include the option of ignoring certain zones. For example, I have 3 doors and 2 motions on my alarm. One of the motions is the main living area and it sees motion constantly throughout the day. There is no point of constantly logging that zone so I included the option to exclude zones of your choice.

Add this line at the top near the variable declarations:
Code: Select all
IGNORE_ZONE_LIST = [4,5]


Change the "handle_zone_fault" function to the following:
Code: Select all
def handle_zone_fault(sender, zone):
        for z in IGNORE_ZONE_LIST:
                if zone == z: return
       
        logging.info('Zone Fault:'+str(zone))


Change the "handle_zone_restore" function to the following:
Code: Select all
def handle_zone_restore(sender, zone):
        for z in IGNORE_ZONE_LIST:
                if zone == z: return
       
        logging.info('Zone Restore:'+str(zone))

I am currently running the base PI Raspbian Image downloaded from teh NuTech site. I would like to add this Email capability to my system. I need the Alarmdecoder running so I can use my tablet as a kepad but I would like to add this email functionality to the PI. Any guidance on how to do this? I am a windows developer but don't have a lot of experience with the Linux platform.

Howdy.

Since you're running our pre-configured image the device is already exposed on port 10000 through ser2sock so you can use it from multiple applications. You can make a couple easy tweaks to danimal's code to have it use a SocketDevice instead of directly talking to the serial port.

Take a look at this for an example.

As an aside, if you're running the 2013-12-31 version of our image I'd recommend upgrading the alarmdecoder python package from 0.5 to 0.6, as it fixes an ugly cpu-use issue:

Code: Select all
sudo pip install alarmdecoder --upgrade

Thanks for this great contribution!

You can add a neat feature to this using the LRR messages by adding

Code: Select all
device.on_lrr_message += handle_lrr_message


to main() and a handler that pulls the disarm code used to identify who disarmed (or armed) the system. I use a big gnarly if statement for matching a code number to a real name, but there's probably a cleaner way of doing that.

Something along these lines:
Code: Select all
def handle_lrr_message(sender, message):
   if message.event_type == 'OPEN':
      if message.event_data == '000':
         USERNAME = 'keypad'
      elif message.event_data == '001':
         USERNAME = 'installer'
      elif message.event_data == '002':
         USERNAME = 'Me'
      elif message.event_data == '003':
         USERNAME = 'Wife'
      elif message.event_data == '004':
         USERNAME = 'KidA '
      elif message.event_data == '005':
         USERNAME = 'KidB'
      else:
         USERNAME = 'Unknown'
      lrrText = "Alarm disarmed by {0}".format(USERNAME) 
      logging.warning(str(lrrText))
      Send_Email(EMAIL_FROM, SMS_TO, EMAIL_SUBJECT, lrrText)

Well, I tried this and am oh so close. I get a couple of my email messages and then it just locks up at the point it is trying to log into the email account. Any ideas? I put in the logout as a last ditch attempt. Not sure if it is required or not.
Code: Select all
import time, logging, smtplib
from email.mime.text import MIMEText
from alarmdecoder import AlarmDecoder
from alarmdecoder.devices import SocketDevice
#from smtplib import SMTP
#from smtplib import SMTP_SSL
#from smtplib import SMTPException

# Configuration values
HOSTNAME = 'localhost'
PORT = 10000

LOG_FILE = '/var/log/alarm.log'      # Make sure you have permission to write this file
EMAIL_USERNAME = 'myemail@yahoo.com'   # Username to login to your SMTP server
EMAIL_PASSWORD = 'password'      # Password for your SMTP account
EMAIL_HOST = 'smtp.mail.yahoo.com'      # SMTP server
EMAIL_FROM = 'myemail@yahoo.com'      # Your email address
EMAIL_TO = '5555555555@vtext.com'      # Destination email

It worked for me with a few exceptions.

1. I had to remove the .logout() this function did not work with the following exception
('Exception', AttributeError("SMTP_SSL instance has no attribute 'logout'",))
2. I had to uncomment out the Exception import from the lib for this error
('Exception', NameError("global name 'SMTPException' is not defined",))


You say you got a few messages then it stopped. I think your debugging is good it should show all steps in sending the email. If its stopping at logging in then I suspect something is blocking your email or yahoo is using a tar pit.

Try a different host such as gmail to confirm or use tcpdump to capture the traffic and see what is going on.

If I run it and then arm my security system, I get the Text Message that it was armed. I then disarm the system and it gets to the point where it says SMTP server created. It hangs for a while and then eventually gives me an error, 4.3.2 Internal server error (6530). It will then send a valid Armed text message. I can do this serveral times and it may be the Arm or the disarm message that gets the failure. Any ideas? By the way, I removed the items you mentioned such as the SMTPException and the Logout.

I have a couple ideas:

You might try .quit() instead of .close(). Using .close() will just close the socket while .quit() sends a QUIT to the server. Yahoo may not like the fact that you aren't shutting your sessions down correctly in addition to the fact that not conforming to the RFC for SMTP is generally indicative of spam.

If that doesn't fix it, a little googling says that an SMTP 4.3.2 error typically indicates that you should try sending the email again. Seems to occur for a variety of reasons, but I'm guessing yahoo is likely throttling sends to prevent spam.

If you're running this on a Raspberry Pi (or another linux box) you might try installing sendmail and sending via localhost to see if you see the same issue. You could also set up an email account on gmail and try sending through them.

If you want to go a little more crazy you could handle the exceptions and queue it up for sending later, or set up an account with Twilio and skip the email gateway entirely.
