Doorbell Ding Dong Ring Ring Doorbell

A doorbell chime controller for my house. Runs on a Raspberry Pi and talks to wifi Unifi G4 Doorbells.

Setup

Misc

Set up user account, add user to sudo, adm, gpio groups.

Set up wifi:

$ sudo raspi-config
- System Options -> Wireless LAN -> Canada
- Enter wifi credentials
- Reboot

If wifi doesn't work, you're on your own.

For the watchdog to work, we need write access to /dev/watchdog/.

Configure /etc/udev/rules.d/60-watchdog.rules:

KERNEL=="watchdog", MODE="0666"

Change the hostname:

$ sudoedit /etc/hostname
$ sudoedit /etc/hosts

Script

Install dependencies:

$ sudo apt update
$ sudo apt install python3 python3-pip python-virtualenv python3-virtualenv supervisor python3-rpi.gpio

Make sure you have at least Python 3.9 installed.

Clone this repo:

$ cd
$ git clone https://tanner@git.tannercollin.com/tanner/doorbelldingdongringringdoorbell.git
$ cd doorbelldingdongringringdoorbell/
$ virtualenv --system-site-packages -p python3 env
$ source env/bin/activate
(env) $ pip install -r requirements.txt

Edit settings for your setup:

$ cp settings.py.example settings.py
$ vim settings.py

Now you can run the script to test:

$ source env/bin/activate
(env) $ DEBUG=true python main.py  # no watchdog
(env) $ python main.py             # uses watchdog

The watchdog will activate if a doorbell is pressed. It will reboot the Pi if the script stops.

Process management

The script is kept alive with supervisor.

Configure /etc/supervisor/conf.d/doorbell.conf:

[program:doorbell]
user=tanner
directory=/home/tanner/doorbelldingdongringringdoorbell
command=/home/tanner/doorbelldingdongringringdoorbell/env/bin/python -u main.py
stopasgroup=true
stopsignal=INT
autostart=true
autorestart=true
stderr_logfile=/var/log/doorbell.log
stderr_logfile_maxbytes=10MB
stdout_logfile=/var/log/doorbell.log
stdout_logfile_maxbytes=10MB

Then run:

$ sudo supervisorctl reread; sudo supervisorctl reload

Script logs to /var/log/doorbell.log. Remove -u from the above command when you're done testing to save SD card writes.
