Raspberry Pi garage door opener

garage-door

(Project under development)

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').

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!)

Fritzing schematic:

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:

• HTML/CSS/JS & React, Node.js, Express.js (REST API), socket.io, lowdb (JSON DB), Sendgrid API

TODO:

• HTTPS (self-signed cert)
• Add laser beam switches with reflector (stops & reverses the door when interrupted, for safety reasons)
