How to send a boot email from your Raspberry PI?

Let your Raspberry PI automatically send you an email with it’s current IP-address whenever it starts. Very handy for Remote Desktops or SSH connections and such!

• create a Python script, for instance ‘/home/pi/Code/startup_mailer.py’
  sudo mkdir /home/pi/Code
  sudo nano /home/pi/Code/startup_mailer.py
  
• Paste the following code in the new file and replace the red text with your own data:
  import subprocess
  import smtplib
  import socket
  import os
  from email.mime.text import MIMEText
  import datetime
  # Change to your own account information
  to = ‘‘
  gmail_user = ‘‘
  gmail_password = ‘mygmailpassword‘
  smtpserver = smtplib.SMTP(‘smtp.gmail.com’, 587)
  smtpserver.ehlo()
  smtpserver.starttls()
  smtpserver.ehlo
  smtpserver.login(gmail_user, gmail_password)
  today = datetime.date.today()
  # Very Linux Specific
  arg=’ip route list’
  p=subprocess.Popen(arg,shell=True,stdout=subprocess.PIPE)
  data = p.communicate()
  split_data = data[0].split()
  ipaddr = split_data[split_data.index(‘src’)+1]
  # Get the current CPU speed
  f = os.popen(‘/opt/vc/bin/vcgencmd get_config arm_freq’)
  cpu = f.read()
  mail_body = “CPU speed: ” + cpu + “IP address: %s” % ipaddr
  msg = MIMEText(mail_body)
  msg[‘Subject’] = “RasPI @ “+ipaddr+” started up on %s” % today.strftime(‘%b %d %Y’)
  msg[‘From’] = gmail_user
  msg[‘To’] = to
  smtpserver.sendmail(gmail_user, [to], msg.as_string())
  smtpserver.quit()
  
• make it automatically run whenever the RPi is booting:
  sudo nano /etc/rc.local
• add a new line:
  if [ “$_IP” ]; then
  printf “My IP address is %s\n” “$_IP”
  python /home/pi/Code/startup_mailer.py
  fi
