• Adding timing to push-button

  Evghenii • 09/12/2017 at 12:15 • 0 comments

  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

  Evghenii • 09/11/2017 at 14:24 • 0 comments

  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

• That is how it looks now

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

• Telegram bot

  Evghenii • 08/01/2017 at 07:10 • 0 comments

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

  Face.py

  # -*- coding: utf-8 -*-
  import config
  import telebot
  import os
  import time
  import requests
  import subprocess
  import simplejson
  import sys
  from telegram import InlineKeyboardButton, InlineKeyboardMarkup

  bot = telebot.TeleBot(config.token)
  @bot.message_handler(content_types=["text"])
  def any_msg(message):
      keyboard = types.InlineKeyboardMarkup()
      keyboard2 = types.ReplyKeyboardMarkup(row_width=2, resize_keyboard=True)
      callback_button1 = types.InlineKeyboardButton(text="Open", callback_data="open")
  #    callback_button2 = types.InlineKeyboardButton(text="Last Photo", callback_data="photo")
      keyboard.add(callback_button1)
      bot.send_message(message.chat.id, "Welcome!", reply_markup=keyboard)
  @bot.callback_query_handler(func=lambda call: True)
  def callback_inline(call):
      if call.message:
          if call.data == "open":
              script1 = subprocess.check_output("sshpass -p a ssh root@10.14.0.63 sh /home/pi/Documents/open.sh 2>/dev/null", shell=True)
              bot.edit_message_text(chat_id=call.message.chat.id, message_id=call.message.message_id, text=script1)
  #        if call.data == "photo":
  
  #            bot.edit_message_text(chat_id=call.message.chat.id, message_id=call.message.message_id, text=script2)
  if __name__ == '__main__':
      bot.polling(none_stop=True)
  def run(self):
          while True:
              self.updates()
              time.sleep(1)
  if __name__ == '__main__':
      bot.polling(none_stop=True)
