Smart-Doorbell

A wifi-connected raspberry pi doorbell with video chat

Github repository for the Smart Doorbell Hackershack video

This project was run on a Raspberry Pi 3 with Raspbian Buster. The video call wasn't as smooth as I would've liked, so it would probably be better to run this on a Pi 4. However, I haven't run this on the Pi 4, so I can't guarantee that it works.

Instructions

Enable the Camera

Enable the camera with raspi-config

In the terminal, type:

sudo raspi-config

Navigate to Interfacing Options

Navigate to camera

Select yes and reboot

Test that the camera is working by running the following command in the terminal to save an image to your home directory

sudo raspistill -o test.jpg

Enable the Microphone

Open the sound input settings

alsamixer -c l

Press F4 to open the capture settings and bump the level up to 100. Press Esc to exit.

Test the audio capture with the following command:

arecord --device=hw:1,0 --format S16_LE --rate 44100 -c1 test.wav -V mono

press control-c to stop. It will generate a audio file in your local directory called test.wav

You can play the file with

aplay test.wav

Store the settings so that they persist on reboot

sudo alsactl store

Enable Video Calls

Visit Jitsi Meet and configure the site to use your camera/microphone

My settings were:

Camera: mmal service 16.1
Microphone: USB PnP Sound Device, USB Audio-Default Audio Device

Download the Code

I navigated to the repo from my Raspberry Pi in the browser and clicked "Download Zip". I extracted the package to my home directory and them moved the doorbell.py file to /home/pi/doorbell.py.

You can test that the program works by running

python doorbell.py

from /home/pi.

To edit the file, install vim and open the file

apt-get install vim

vim doorbell.py

press, i to enter edit mode then make your changes. To exit, press esc then upper-case ZZ to save.

The variables for the code are documented at the top. Feel free to change any of these for your program.

Rotate the Screen

Open the boot.txt file with vim

sudo vim /boot/config.txt

press i to enter insert mode then add a line

display_rotate=1

press esc then ZZ to save and exit. Reboot.

Start the Program on Boot

Create a autostart directory

mkdir /home/pi/.config/autostart

Create a file to run the doorbell program

vim /home/pi/.config/autostart/doorbell.desktop

press i, then add the following to the file

[Desktop Entry]
Type=Application
Name=Doorbell
Exec=python /home/pi/doorbell

press esc and ZZ to save and exit.

*WARNING: This will make your local display unusable. Make sure you have a way to connect to the pi through VNC or SSH to remove this file if you want to stop the program from starting at boot.

Reboot.

If you have any issues getting the doorbell to start, please leave an issue on this repository and the community will help you get it working.

Jitsi now start with a 'Join meeting' page

If you go to a meeting link you will now get a 'Join meeting' page instead of immediately joining the meeting.
This breaks the whole system as the raspberry does not joins the meeting without clicking the 'Join' button...

Camera Config and code issues

Hello, first of all I would like to thanks you for your project.
Even if had some difficulties making ti works, seems that it do not like to run over ssh...

I may have a little request and im kind of stuck.

Due to civid 19 my shop isn't allowed to welcome more than a few people at the time, there is a lot of personne waiting outside and that why I was interested in this sytem.
Being able to start a conf call from outside and trying to serve them at our best.
In this situation I'm not able to use a define sleep time as every client is different.
I could not manage to find a solution at my problem, I would like to stop and loop the program from a distant computer, I'm thinking about remote button, or button but I'll find myself with 40m of wire.
I would like to know if you could think about something easy to do it right ?
