motion.py

Python
This is similar to the motion detector code with the addition of adding support for the raspberry pi camera. There are a lot of options you can add to adjust your camera settings, but I just used the defaults.

report2.sh

SH
This script should be placed in a cron job to run once a day. It will make a internet connection using the Nova Modem, run the report and then disconnect.

Once the report is sent, it will move the images from the images folder to the archive folder.
#/bin/bash

sudo hologram network connect
python emailreport.py
sudo hologram network disconnect

mv images/*.jpg archive

report.sh

SH
This is the script that is run every night at 11:55pm, it does a count of all the jpg images taken and send that number to holograms cloud where it will format a message, emailing it to me to let me know how many images were taken that day.

I wanted to send all the file names, but I keep running into issue around the size of the message. If I can figure that out, I will update the script to send the image file names.
#/bin/bash
value=$(ls -l *jpg | wc -l)
sudo hologram send -v --cloud --devicekey 'YOUR KEY' --topic 'report' $value
mv *.jpg archive

emailreport.py

Python
This will generate a list of images in the images directory and email them out to you

You will need to update the following properties to your specific values
SMTPserver = 'smtp.sendgrid.net'
sender = 'youremail@somewhere.com'
destination = ['someemail@somewhere.com']
USERNAME = "your username"
PASSWORD = "your password"
#! /usr/local/bin/python
import sys
import os
import re
import glob

from smtplib import SMTP_SSL as SMTP       # this invokes the secure SMTP protocol (port 465, uses SSL)
# from smtplib import SMTP                  # use this for standard SMTP protocol   (port 25, no encryption)
from email.mime.text import MIMEText

SMTPserver = 'smtp.sendgrid.net'
sender =     'youremail@somewhere.com'
destination = ['someemail@somewhere.com']
USERNAME = "your username"
PASSWORD = "your password"

# typical values for text_subtype are plain, html, xml
text_subtype = 'plain'

subject="Sent from Trail Cam 1"

try:
    files = glob.glob("images/*.jpg")
    files.sort(key=os.path.getmtime)
    #print("\n".join(files))

    if len(files) > 0:
        content="There were " + str(len(files)) + " images taken today:\n\n" + str("\n\r".join(files)).replace("images/", "").replace(".jpg", "") + "\n\nThank you"
    else:
        content="There were no images taken today\n\n\nThank you."

    msg = MIMEText(content, text_subtype)
    msg['Subject']=subject
    msg['From']=sender # some SMTP servers will do this automatically, not all

    conn = SMTP(SMTPserver)
    conn.set_debuglevel(False)
    conn.login(USERNAME, PASSWORD)
    try:
        conn.sendmail(sender, destination, msg.as_string())
    finally:
        conn.quit()

except Exception, exc:
    sys.exit( "mail failed; %s" % str(exc) ) # give a error message

emailimage.py

Python
This will listen for an imcomming SMS message from the Nova modem, take the message, which should be a filename from the email report, compress the image then email to you.

You will need to update the following properties for your email provider
SMTPserver = 'smtp.sendgrid.net'
sender = 'youremail@somewhere.com'
destination = ['someemail@somewhere.com']
USERNAME = "your username"
PASSWORD = "your password"

It should also be noted you will need root privileges in order to run it.
You will need Python Image Library installed to do the image compression
#! /usr/local/bin/python
import sys
import os

from Hologram.HologramCloud import HologramCloud

from smtplib import SMTP_SSL as SMTP       # this invokes the secure SMTP protocol (port 465, uses SSL)
from email.mime.text import MIMEText
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email import Encoders

#Used for image compression, requires Python Image Library Installed
import StringIO
from PIL import Image


#Setup email properties
SMTPserver = 'smtp.sendgrid.net'
sender =     'youremail@somewhere.com'
destination = ['someemail@somewhere.com']
USERNAME = "your username"
PASSWORD = "your password"

# typical values for text_subtype are plain, html, xml
text_subtype = 'plain'

subject="Image requested from Trail Cam 1"

def sendEmail(filename):
    #Compress the image requested before emailing it out
    #filename="test"
    im1 = Image.open("archive/" + filename + ".jpg")
    buffer = StringIO.StringIO()
    im1.save(buffer, "JPEG", quality=50)
    with open("tmp/" + filename + "X.jpg", "w") as handle:
        handle.write(buffer.getvalue())

    try:
        #msg = MIMEText(content, text_subtype)
        msg = MIMEMultipart()
        msg['Subject']=       subject
        msg['From']   = sender # some SMTP servers will do this automatically, not all

        part = MIMEBase('application', "octet-stream")
        #part.set_payload(open("2018-01-10_20:23:23.189189.jpg", "rb").read())
        part.set_payload(open("tmp/" + filename + "X.jpg", "rb").read())
        Encoders.encode_base64(part)

        part.add_header('Content-Disposition', 'attachment; filename="2018-01-10_20:23:23.189189.jpg"')

        msg.attach(part)

        conn = SMTP(SMTPserver)
        conn.set_debuglevel(False)
        conn.login(USERNAME, PASSWORD)
        try:
            conn.sendmail(sender, destination, msg.as_string())
        finally:
            conn.quit()

        os.remove("tmp/" + filename + "X.jpg")
    except Exception, exc:
        #sys.exit( "mail failed; %s" % str(exc) ) # give a error message
        print "Failed to send email\n " + str(exc) 



# this function now pops the received message and prints it out.

def sayHelloReceivedAndPopMessage():
  print "hello! I received something!"
  sms_obj = hologramCloud.popReceivedSMS()
  print sms_obj.message
  sendEmail(sms_obj.message)


hologramCloud = HologramCloud(dict(), network='cellular')
print hologramCloud.version # Prints 0.7.0
print hologramCloud.network_type # Prints either 'Network Agnostic Mode' or 'Cellular'

hologramCloud.event.subscribe('sms.received', sayHelloReceivedAndPopMessage)

# someone sends a "this is the payload" message
# prints "hello! I received something!"
# prints "this is the payload"

while (1):
  time.sleep(100)
  sms_obj = hologramCloud.popReceivedSMS() # prints None
