Smart Bed

See working prototype at www.zack.land

This app is running on a RaspberryPi 3 B+. There are 5 independent RGBWWCW LED strips to set multiple lighting configurations. There are 4 load cells (2 for each side of the bed) that dectect user presence. There are rocker switches on each side of the bed to toggle built in night lamps.

Installation

Open Lighting Project

OLA installation instructions for Ubuntu here

OLA is not python 3 compatable, so in order to install what is needed, run:

python3 -m pip install

in main directory, create a file called status.json.

Also in main directory, create a file called environment.py, and fill out the following fields:

import os

os.environ['DEVICE_ROOM'] = 'Your Bedroom name'

# for sun tracking
os.environ['DEVICE_LATITUDE'] = ''
os.environ['DEVICE_LONGITUDE'] = ''

# pin mapping of the 4 load cells
os.environ['LOAD_CELL_LEFT_DT'] = ''
os.environ['LOAD_CELL_LEFT_SCK'] = ''
os.environ['LOAD_CELL_RIGHT_DT'] = ''
os.environ['LOAD_CELL_RIGHT_SCK'] = ''

# pin mapping of the rocker switches
os.environ['ROCKER_LEFT_UP'] = ''
os.environ['ROCKER_LEFT_DOWN'] = ''
os.environ['ROCKER_RIGHT_UP'] = ''
os.environ['ROCKER_RIGHT_DOWN'] = ''

os.environ['API_PORT'] = '8080'

os.environ['HOME_AUTOMATION_URL'] = ''

Start App

to start the app run:

nohup python3 smart_bed &

You can now open status.json and be able to see all the data that the bed tracks:

{
    "room": "Your Room Name",
    "is_occupied_left": false,
    "time_last_occupied_left": null,
    "is_occupied_right": false,
    "time_last_occupied_right": null,
    "context": "night",
    "time_lamp_on_left": null,
    "time_lamp_on_right": null,
    "is_fun_mode": false,
    "volume_change": 0
}

End App

to end the app, first get the pid by running:

ps -ef |grep smart_bed

then end it:

kill <pid>
