DataHubHel is an IoT platform for Helsinki.
Work on progress. Come back in a few weeks or so.
The project consists of the following parts:
- API backend powered by Django Rest Framework.
- React app for testing log-in flows and Thing/Service registration.
- Docker containers for running a SensorThings Server and a MQTT Broker.
First create a Python virtualenv:
virtualenv -p python3.6 venv . venv/bin/activate
Then install the Python packages to the virtualenv:
pip install prequ prequ sync backend/requirements*.txt
And create a PostgreSQL database:
sudo -u postgres createuser -d -P datahubhel sudo -u postgres createdb -O datahubhel datahubhel
SensortThings Server and MQTT Broker
The SensorThings Server (STS) and the Mosquitto MQTT Broker can be run using Docker:
cd docker docker-compose up
The command will create two docker images "sts" and "mqttbroker" and run containers using them.
The STS is configured to expose it's HTTP SensorThings API (running on Tomcat) on local port 8080 and the STS's own MQTT broker on port 11883. The STS is also configured to connect to a PostgreSQL server in the host machine. (db: sensorthings, username: sensorthings, password: sensorthings) The database tables can be created by visiting
The mosquitto service is configured to expose itselft on local port 1883. It's also configured to bridge the STS's MQTT Broker. The mosquitto will query authentication and authorization from the local datahubhel backend on port 8000.
