raspberry pi - send email on startup (will need gmail account to send from)
import subprocess
import smtplib
import socket
from email.mime.text import MIMEText
import datetime
# Change to your own account information
to = 'me@example.com'
gmail_user = 'test@gmail.com'
gmail_password = 'yourpassword'
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]
my_ip = 'Your ip is %s' % ipaddr
msg = MIMEText(my_ip)
msg['Subject'] = 'IP For RaspberryPi on %s' % today.strftime('%b %d %Y')
msg['From'] = gmail_user
msg['To'] = to
smtpserver.sendmail(gmail_user, [to], msg.as_string())
smtpserver.quit()

create code dir

mkdir ~/code

save in /home/pi/code/startup_mailer.py

make it executable

cd ~/code
sudo chmod +x startup_mailer.py

add to boot.rc

sudo nano /boot/boot.rc

this...

#Script to email ip address upon reboot
python /home/pi/Code/startup_mailer.py

and if on raspbian

sudo nano /etc/rc.local

this...

# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
  python /home/pi/code/startup_mailer.py
fi
exit 0

This is awesome, might use it for something, can't think of a use yet.

or via a cronjob

crontab -e

then

@reboot python /home/pi/code/startup_mailer.py

looking at it the cron job is more reliable, placing it in the rc.local file fails on wifi

Thanks for the code you posted. On Raspberry Pi 3, Model B, I had to slightly change your startup_mailer.py script when I invoke it using Cron at booting time:

tries = 0
while True:
    if (tries > 60):
        exit()
    try:
        smtpserver = smtplib.SMTP('smtp.gmail.com', 587, timeout=30) # Server to use.
        break
    except Exception as e:
        tries = tries + 1
        time.sleep(1)

anassar's workaround worked for me. Then I realized I was calling the script from cron @reboot - without allowing for additional tries, apparently everything the python script needed had not loaded when the script ran and the script failed.
Another solution that works (and if leave anassar's code in the script and print out tries, it ALWAYS only needs 1 try) is to delay the running of the script. Can do in the cron command:
@reboot sleep 300 && python /path/to/python_script.py

Hey There. Thanks for this. Will make remote monitoring of my Pi much easier. Having an issue though.
Gmail refused the sign-in attempt. Sent me an email saying an app without modern security protocols is accessing my account.
Anyone experienced this or found a workaround?

Hey @bereshr1! Is there any chance you are using two step verification on your gmail account? That could be the issue.

nikmart commented Aug 23, 2016

@bereshr1, I just had this issue and needed to allow less secure devices to access gmail. You can look here for that setting: here
