Smart Intercom

Gonna get rid of RPi 1 and NFC in favor of fingerprint scanner connected to RPi3.
Updates are coming...

In order to disable entrance in specific hours via push-button, i made the following  bash script:

#!/bin/bash

H=$(date +%H)
if (( 7 <= 10#$H && 10#$H < 19 )); then 
    echo between 7AM and 19PM
sh /home/pi/action.sh
elif (( 19 <= 10#$H && 10#$H < 7 )); then 
    echo between 19PM and 7AM
sh /home/pi/error.sh
else
    echo go to bed
fi

action.sh - opens the door between 7 am and 19 pm

error.sh - displays restriction image between 19 pm and 7 am

error.sh script

#!/bin/bash
DISPLAY=:0.0 XAUTHORITY=/home/pi/.Xauthority /usr/bin/feh --hide-pointer -x -q -D 5 -B black -F /home/pi/error.png &
ping -c 4 localhost 2>/dev/null
DISPLAY=:0.0 XAUTHORITY=/home/pi/.Xauthority xdotool key "x"

P.S to run this script you will need to install xdotool

sudo apt install xdotool

Temporary solution for any visitors, push the button and enter.
In my case it is needed in day time, because of many visitors throughout the day.
Gonna make it schedule to enable/disable in day/night time.

feh --hide-pointer -x -q -D 5 -B black -F /path/to/image.png

I know it's ugly. Want to hide all that with some pretty sticker.

Made telegram bot for Smart Intercom. It sends last pic when buttons is pressed and can open the door.

Added pushbutton to Smart Intercom.

It sends you last photo to telegram bot and sends notification to Ubuntu Desktop PC.

Adding pushbutton to smart intercom.

Got some ideas what should it execute, still deciding 

Working on WEB interface for Smart Intercom.

Now it has only open and close buttons. Planning to add photo upload to register new people for recognition.
