Synthia is an intelligent assistant that sends you off in the morning with helpful reminders, then welcomes you home at the end of each day. This is done using motion detection triggered by a camera built into a Raspberry Pi. If motion is detected within a certain time range in the morning or evening, it will trigger functions to play a customized message.

Synthia is written in Python 2.7.

1. Raspberry Pi 3 Model B with Raspbian Jessie
2. Pi NoIR camera
3. Bluetooth speaker (or 3.5mm powered speaker)
4. Optional: PIR Sensor (to only process images when movement is detected)

1. Install Python 2.7 on Raspberry Pi
2. Install OpenCV on the Raspberry Pi with OpenCV-for-Pi (or if you want to compile OpenCV on the Pi: http://www.pyimagesearch.com/2016/04/18/install-guide-raspberry-pi-3-raspbian-jessie-opencv-3)
3. Install virtualenv for Python if you have not already done so by running sudo pip install virtualenv.
4. Run the following commands to setup virtualenv within this repository folder on the Raspberry Pi:

   sudo apt-get install python-dev python-all-dev libjpeg-dev vlc libffi-dev libssl-dev flac
   
   # Setup virtualenv (change directory to repository directory if you haven't already)
   pip install virtualenv
   virtualenv --no-site-packages synthia-virtualenv
   source synthia-virtualenv/bin/activate
   
   # Install pip modules (this could take a while):
   pip install -r requirements.txt
   
   # Install OpenCV in virtualenv (OpenCV-for-Pi does not work in virtualenv by default)
   wget "https://github.com/jabelone/OpenCV-for-Pi/raw/master/latest-OpenCV.deb"
   dpkg -x latest-OpenCV.deb ./OpenCV
   cp OpenCV/usr/local/lib/python2.7/dist-packages/cv2.so synthia-virtualenv/local/lib/python2.7/site-packages/
   rm latest-OpenCV.deb

5. Configure the desired audio output device as the system's default on the Raspberry Pi
6. Set the correct timezone on the Raspberry Pi

Execute the following line on the Raspberry Pi:

# or with a custom config:
python synthia.py --config=my-config.json --user=<YOUR_NAME>

Execute the following line on the Raspberry Pi:

python synthia.py

# or with a custom config:
python synthia.py --config=my-config.json

The default configuration is to each day execute exactly one morning event between 6:00 and 10:00 and exactly one welcome home event between 18:00 and 23:00. These times are relative to the current time on the Raspberry Pi.
