Newbie with Pi3

[buran]

After your last post yesterday I was thinking how to minimize the false edge detections
So I change the code to use callback function. Now only event it detects is change in light sensor ans I also increased bounce time to 200 ms, i.e. it will not detect new event within 200 ms of the last one

import RPi.GPIO as GPIO
import time
from datetime import datetime
from twilio.rest import Client

GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)
GPIO.setup(7,GPIO.IN)   #LDR (Light Dependent Resistor)
  
GPIO.setup(11, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) #top switch
GPIO.setup(12, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # bottom switch
  
GPIO.setup(15,GPIO.OUT) # Door Open
GPIO.setup(13,GPIO.OUT) # Door Close
  
  
def send_sms(sms_text="Hello from Python!"):
    twilio_client = Client("ACxxxxxxxxxxxxxx", "zzzzzzzzzzzzz")
    client.messages.create(to="+19732644152", 
                           from_="+12023351278", 
                           body=sms_text)


def operate_door():
    if not GPIO.input(7) and not GPIO.input(11): # it's day and door is not open
        print ("Day. Open door")
        print ("Start motor. Time is {}".format(datetime.now().strftime('%d %b %Y %H:%M:%S.%f')))
        GPIO.output(15,True)
        while True:
            if GPIO.input(11):
                GPIO.output(15,False)
                print ("STOP. Door open. Time is {}".format(datetime.now().strftime('%d %b %Y %H:%M:%S.%f')))
                break
        #send_sms("sms_text='Door opened'")
            
    elif GPIO.input(7) and not GPIO.input(12): # it's night and door is not closed
        print ("Night. Close door")
        print ("Start motor. Time is {}".format(datetime.now().strftime('%d %b %Y %H:%M:%S.%f')))
        GPIO.output(13,True) 
        while True:
            if GPIO.input(12):
                GPIO.output(13,False)
                print ("STOP. Door closed. Time is {}".format(datetime.now().strftime('%d %b %Y %H:%M:%S.%f')))
                break
        #send_sms("sms_text='Door closed'")
           

# add events detection, using separate thread
GPIO.add_event_detect(7, GPIO.BOTH, callback=operate_door, bouncetime=200)
delay = 1 # 1 sec. delay
print('Start monitoring')
while True:
    try:
        time.sleep(delay) # you may change this or replace it with just pass
        #pass #uncomment this if you decide to remove time.sleep above
    except KeyboardInterrupt:
        print('Stop monitoring and quit')
