HomeManager

HomeManager is an Android client which unlock my arduino powered door via bluetooth and my raspberry pi security camera via internet. For now.

Components

Three main components in HomeManager for now :

• client - Android widget client to control the security system
• door - Arduino bluetooth server controlling the door lock
• motioneye - patch for the raspberry pi OS to control the system via an API

Client process

The Android client is a simple widget used to control the door and camera, the application in itself is a blank UI.

Schematic

• JY-MCU for bluetooth
• Relay 5V
• Solenoid door lock
• Arduino UNO
• Transformer 9V

Notes

The bluetooth communication is "secured" by a system of token, AES being hard to implement on both Arduino and Android without rewriting a few things I've taken a much simpler solution with tokens and MD5 : it's easy to use and has a good enough security.

As for motionEye, a hotfix has been made to allow external call to use a custom API to toggle the alarm system of the camera, in the future it should be taken off since it was in the TODO list of the maintainer.
