garage-door

Project under development. READ DISCLAIMER ON THE BOTTOM

https://news.ycombinator.com/item?id=23174493

A garage door remote control system, that can open / close / freeze the door through a mobile app or physical wall (up & down) pushbuttons (NO or 'normally open').

A breadboard prototype

Features

• User accounts, authentication & authorization, email verification
• Role assignments & permissions
• Garage door & UI responsiveness via realtime communication & connection/signal status.
• Works locally only, via WLAN (it's a feature, not a bug!)

Installation instructions

$ git clone https://github.com/evzaboun/garage-door.git

$ cd garage-door

$ npm install

$ cd client

$ npm install

$ cd ..

Setting the environment variables

$ touch .env

$ nano .env

Add the following

NODE_ENV=development
IP = "YourRaspberryPiIP"
HOSTNAME = `${os.hostname() + ".local"}`
JWT_KEY = "SetYourJWTKeyHere"  # Can be any string as your secret
SENDGRID_API_KEY = "YourSendgridAPIKey" # Used for user email verification
SENDGRID_FROM_EMAIL = "yourVerifiedSendgridSenderEmail@example.com"
REGISTER_LINK = "http://YourRaspberryPiIP:AndPort/activate"

Save the .env file, and run:

$ npm run dev

Used the following tools

Hardware

• Raspberry Pi Zero WH (1x)
• 2 channel relay module (with optocoupler isolation & snubber circuitry, compatible with raspberry pi, the one I use for the project is "active low") (1x)
• A 5v DC power supply in order to use the relay optocoupler isolation (for safety reasons!) (1x)
• Magnetic reed switches (future implementation) (2x)

Software stack & tools

Server

Node.js, Express.js (REST API), socket.io, lowdb (JSON DB), Sendgrid API

Client

HTML/CSS/JS & React & Material UI, socket.io

TODO

• Simplify wiring (utilizing built in raspberry pi's pull up resistors)
• HTTPS (self-signed cert)
• Add laser beam switches with reflector (stops & reverses the door when interrupted, for safety reasons)
