IoT Server (v0.9.0)

Simple IoT Server, Configuration Tool & Dashboard

Requirements

• Python 3.9+
• Git
• Mosquitto
• PostgreSQL
• PostGIS
• gdal

Installation

git clone https://github.com/hacklabza/iotserver.git
cd iotserver/
pyenv local 3.10.*
poetry install
poetry run pre-commit install

Run the server to test your installation

poetry run ./manage.py migrate
poetry run ./manage.py runserver

Testing

poetry run pytest -s . --cov

Getting Started

To create a super user which you can use to populate your devices and users, execute the following command in your terminal and follow the prompts.

./manage.py createsuperuser

Deployment (Docker)

The recommended way to install the API and it's service dependancies is with docker, however the docker-compose config can also be used in development. I've found that this is best done if you're using a PC or Server.

Doesn't play well with RPi!

System Dependancies

sudo apt update && sudo apt upgrade
sudo apt install libffi-dev libssl-dev python3-dev python3 python3-pip git

Docker Compose Setup

Setting up docker

curl -fsSL test.docker.com -o get-docker.sh && sh get-docker.sh
sudo usermod -aG docker ${USER}
sudo systemctl enable docker
sudo reboot now  # or logout of the pi user account

Setting up docker-compose, the project and environment

pip3 install docker-compose
git clone https://github.com/hacklabza/iotserver.git
cd iotserver/
curl -#fLo- 'https://raw.githubusercontent.com/hyperupcall/autoenv/master/scripts/install.sh' | sh  # install autoenv - optional
cp .env.example .env  # update as required
mkdir -p docker/mqtt
cp mosquitto.conf.example docker/mqtt/mosquitto.conf
docker compose -f docker-compose.yml up

Deployment (Manual)

Recommend for 64bit/32bit rasbian installation, in my case a raspberrypi zero.

System Dependancies

sudo apt update && sudo apt upgrade
sudo apt install -y --no-install-recommends git vim python3-pip python3-dev gdal-bin libgdal-dev libffi-dev openssl

PostGIS Setup

sudo apt install -y postgresql
sudo chown postgres:postgres /var/lib/postgresql/13/main
sudo apt install -y postgresql-13-postgis-3-scripts
sudo su - postgres
createdb iotserver
psql -d iotserver
$postgres-# CREATE EXTENSION postgis;
$postgres-# ALTER USER postgres WITH PASSWORD '<your-postgres-password>';

Memcached Setup

sudo apt install -y --no-install-recommends memcached

MQTT Setup

sudo apt install -y --no-install-recommends mosquitto

Add the following lines to /etc/mosquitto/mosquitto.conf and restart the service

persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log
listener 1883
max_keepalive 0  # Remove if this causes startup issues
allow_anonymous true

API Setup

You may need to install the rust toolchain for RPi 32 bit OS versions due to cryptography.

git clone https://github.com/hacklabza/iotserver.git
cd iotserver/

pip install --upgrade pip
curl -sSL https://install.python-poetry.org | python3 -
poetry install

curl -#fLo- 'https://raw.githubusercontent.com/hyperupcall/autoenv/master/scripts/install.sh' | sh  # install autoenv - optional but recommended
cp .env.example .env  # update as required
cp manage.py ~/.local/bin/
chmod +x ~/.local/bin/manage.py

poetry run manage.py migrate
poetry run manage.py collectstatic
poetry run manage.py createsuperuser

sudo cp systemd/iot.api.service /etc/systemd/system/iot.api.service
sudo cp systemd/iot.mqttsubscriber.service /etc/systemd/system/iot.mqttsubscriber.service

sudo systemctl start iot.api.service
sudo systemctl start iot.mqttsubscriber.service

sudo systemctl enable iot.api.service
sudo systemctl enable iot.mqttsubscriber.service

Make a SD Card Backup

Read more here: https://howchoo.com/pi/create-a-backup-image-of-your-raspberry-pi-sd-card-in-mac-osx. this pretty useful as cards can become corrupt if power is cut or the device is not powered down correctly.
