Schematics

RE: Switches and the BBBW

This is the schematic, although mundane, it is for your viewing simplicity.

Code

The emailer.py file...

Python
Use this file alone or w/ the other script to send yourself emails or send your friends the emails. We will call the alertMe function in another Python file w/ a Flask microframework to make sure we can get real time happening.
import smtplib
from email.mime.text import MIMEText

def alertMe(subject, body):
    myAddress = "YourEmail@gmail.com"
    msg = MIMEText(body)
    msg["Subject"] = subject
    msg["From"] = "YourEmail@gmail.com"
    #msg["Reply-to"] = "YourEmail@gmail.com"
    msg["To"] = "YourEmail@gmail.com"

    server = smtplib.SMTP("smtp.gmail.com", 587)
    server.starttls()
    server.login("YourEmail@gmail.com", "YourPassword")
    server.sendmail("YourEmail@gmail.com", "YourEmail@gmail.com", msg.as_string())
    server.quit()

alertMe("Hello!", "The front door has been opened!")

RE: DoorAlert.py

Python
This will tell you whether the switch has been completed or broken w/ a nice Flask App online at your BBBW address with the port of 5000. You can try this one separately for fun!
from flask import Flask, render_template
import Adafruit_BBIO.GPIO as GPIO
app = Flask(__name__)

GPIO.setup("P8_8", GPIO.IN)

@app.route("/")

def hello():
    if GPIO.input("P8_8"):
        doorStatus = "open"
    else:
        doorStatus = "closed"
    templateData = {
        "doorStatus": doorStatus,
    }
    return render_template("mainDoor.html", **templateData)

if __name__=="__main__":
    app.run(host="0.0.0.0", port=5000, debug=True)

RE: DoorAlert.py is our software to use w/ the emailer.py file from before.

Python
Hello...there is a lot going on in the source. At least for me, it is a bit difficult to explain. If you have any questions, do not hesitate to reply or let me know how you would go about it.
import Adafruit_BBIO.GPIO as GPIO
import time
from emailer import alertMe

GPIO.setup("P8_8", GPIO.IN)

alertTime = 0

while True:
    if GPIO.input("P8_8"):
        if alertTime == 0:
            alertTime = time.time() + 15
            print("The door has been opened! This message will alert you in 15 seconds if left open!")
        else:
            if time.time() > alertTime:
                alertMe("Alert, Alert!", "The door has been left open!")
                print("The door has been left open for 15 seconds. The email has been sent.")
                while GPIO.input("P8_8"):
                    time.sleep(0.5)

    else:
        alertTime = 0
    time.sleep(0.5)
