Hardware

• Raspberry Pi
• Microswitch
• DHT22 Temperature and Humidity sensor

Using Docker

Prepare

sudo apt-get update && sudo apt-get upgrade -y

# Required for docker-compose and git
sudo apt-get install -y git python3-pip

# Install docker
curl -sSL https://get.docker.com | sh
sudo usermod -aG docker pi

# Install docker-compose
sudo pip3 install docker-compose

Run sensor_monitor

git clone https://github.com/ilirb/sensor_monitor.git
cd sensor_monitor

docker-compose up

# to run in background and start on boot
docker-compose up -d

# to update
docker-compose pull && docker-compose up -d

# to stop and remove
docker-compose stop
docker-compose down

Run without docker-compose

docker run -p 5000:5000 --privileged ilirb/sensor-monitor:latest

Running without docker

Prepare environment

sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install -y git supervisor authbind python3 python3-pip python3-venv
git clone https://github.com/ilirb/sensor_monitor
cd sensor_monitor

# On non Rasbperry Pi machine (dev)
pip3 install -r requirements.txt

# On Raspberry Pi
pip3 install -r requirements.txt -r requirements-RPi.txt

Setup gunicorn

This is required to allow listening on port 80 without sudo

sudo touch /etc/authbind/byport/80
sudo chmod 500 /etc/authbind/byport/80
sudo chown pi /etc/authbind/byport/80

Supervisor

This makes sensor_monitor run as a service and on boot

sudo ln -s $PWD/sensor_monitor.conf /etc/supervisor/conf.d/sensor_monitor.conf
sudo supervisorctl reread
sudo service supervisor restart

Run manually without supervisor

authbind gunicorn --bind 0.0.0.0:80 run:app

Configuration

Edit application/config.py and adjust pins to sensors/devices connected to Raspberry Pi GPIO

Sensor logic resides in application/devices.py

TODO

• Add multiplatform docker builds (armv7,armv8,arm64)
• Notifications
• Alerts (IFTTT like)
• InfluxDB
• Web authentication
• Web configuration (Sensors, notifications, etc)
