Garage Door Remote Control

Introduction

The Garage Door Remote Control Project is intended to primarily provide a secure method for the Board of Directors, Committee Chairs and select other members to remotely open or close the ramp garage door.

Use cases include closing the door when it is open. It is often left open by members who get distracted after they bring in their projects. We don’t need to be airconditioning all of Carrollton, or letting in humidity and mosquitoes. Another use case would be letting in trades people to fix building issues if no one is available inside the building.

Requirements

Software

• Software for accessing the garage door camera feeds for safety checks
• Software for accessing Active Directory for login control
• Active Directory Group for users

Hardware

• Network connectivity to the DMS network
• Hardware for powering the device via Power over Ethernet (802.3af)
• PoE Wiring to garage door
• Case to protect device from dust
• Hardware for simulating pressing the garage door switches (Relays)
• Maintenance disconnect key switch

Completed Steps

Software

• Demoed early alpha software that displays a fixed camera image and toggles relays
• Created AD Group “CN=Garage Door Controller Access”
• Created AD Service User
• Added Board of Directors group to access
• Added Committee Chairs group to access
• Onsite & Offsite access thru https://physical.dallasmakerspace.org:4444/

Hardware

• Decided on Raspberry Pi 2/3 for cost and ease of prototyping (RPi3 for processor overkill and WiFi)
• Decided on RB-Wav-62 relay board by Waveshare (3 5A relays w/ NO and NC contacts)
• Decided on PoE to 5v Micro USB adapter (UCTRONICS IEEE 802.3af Active PoE to Micro USB 5V 2.4A for Raspberry Pi)
• Installed PoE to garage door
• Installed system in box underneath the switch

Next Steps

Software

• Config page for web page port, relay timing and relay pin number
• Bought/Built icons for screen buttons
• Added buttons to Open, Close and Stop garage door
• Added static camera image
• Added refresh button for camera image
• Active Directory login
• Active Directory RFID (Employee ID) lookup
• Active Directory Member of Group lookup
• Live camera images
• Removed refresh button for camera images
• Hall Effect sensor
• EMail alarm to list if door open x minutes
• Pinhole in firewall for HTTPS://garagedoor.local
• Add option to lockout the door that holds open the “Stop” relay
• Add detail log to existing SQL database

Hardware

• Raspberry Pi 3
• RPi relay board
