This program aims to use a Raspberry Pi (B+ or 2) into a complete and consistent home alarm, monitoring and automation system. It is written in javascript for Node.js has an https web interface using ReST and sockets to communicate between client and server. It's features include burglar alarm, fire alarm, environmental alerts (CO, gas leak, air quality), https interface, mongodb local user authentication, sockets, webcams, and real-time monitoring.
Current status is that the security alarm functionality is complete, environmental systems are still in progress, specifically:
Web interface, https, sockets, authentication, sends notifications, reads digital (PIR, reed, glass break, mechanical fire/temp., etc) sensors,
receives pictures from external webcams (via ftp using vsftpd), uses onboard camera, displays a real-time 'floorplan' image
showing active zones.
Wire the MQ-7(CO), MQ-135(smoke & air quality) and MQ-2(Propane/Gas Leak) sensors to their appropriate heating
circuits and ADC and write interface module. (Fairly trivial but delayed due to Intl shipping of the sensors)
Wire, install and test door striker code (for keyless entry). Goes: Pi 2 -> logic level shifter -> relay -> door striker
Still to do is :
add GPRS/GSM module for backup connection for SMS alerts
Document hardware configuration/wiring for this page. (schematics for: Battery, power supply, ADC, sensors, level shifters, relays, etc.)
Document software prerequisites and installation, including: Mongodb, Node.js, openssh, vsftpd, Node modules, etc.
Build the hardware - https://hackaday.io/project/6390-node-pi-alarm
Install and configure Raspbian -
Install dependencies - 'sudo apt-get install vsftpd openssh'
Install Mongodb, insructions here -http://andyfelong.com/2016/01/mongodb-3-0-9-binaries-for-raspberry-pi-2-jessie/
Install Node.js 0.12.6 - Install this *.deb - http://node-arm.herokuapp.com/node_archive_armhf.deb via 'sudo dpkg -i'
configure vsftpd (edit conf file in /etc)
create ftpcam user with home dir in ./public/pictures/{camera name}
configure any external webcams to connect to your Pi via ftp using the ftpcam user
install Node-Pi-Alarm - 'cd /opt && git clone https://github.com/alphacharlie/Node-Pi-Alarm.git'
configure permissions - 'chown -R pi:pi /opt/Node-Pi-Alarm'
configure openssh as CA and generate cert/key for web server, install to ./cert (I have provided a 'test' key, but it's ONLY for testing!!!)
npm install necessary global modules - '/usr/local/bin/npm -g install node-gyp nodemon mongodb'
npm install necessary modules to Node-Pi-Alarm... 'cd /opt/Node-Pi-Alarm && /usr/local/bin/npm install'
configure Node-Pi-Alarm by editing app.js and providing credentials for Nodemailer and paths to SSL key/cert.
plan out your sensors for zones and entries. (each 'zone' or entry has it's own IO pin. All sensors on the same
zone should be wired in parallel so that any one sensor tripping will light up that zone.)
edit ./config/secret.js (you can generate a random string at https://www.random.org/strings/
configure number of zones and entry circuits and their GPIO pins on server by editing app.js.
configure 'zones' display by editing ./public/js/index.js html canvas code to create your own zone floor plan images!
install nodemon so that it'll restart itself when you change it - 'sudo npm -g install nodemon'
set up and configure iptables for additional security (Block all incoming on eth0 except for ports 80/443)
Please report any bugs to info@boffinry.org
To Michael Herman for his excellent article - http://mherman.org/blog/2013/11/11/user-authentication-with-passport-dot-js which helped TREMENDOUSLY getting local authenticaton up and running!
To Marco Schwartz as this project uses a MODIFIED version of his 'pi-arest' module. It has been edited to move the root 'REST' directory from '/' to '/rest/' (so that the entire service can be secured with middleware in one route...). It has also had the GPIO read/write access REMOVED for security reasons. If you are developing a Node.js app which requires REST, check out his full node module 'pi-arest'!
