Python program to subscribes to the MQTT broker of The Things Network (v3 stack) and saves incoming data into InfluxDB.

TTN (The Things Network) is building a global open LoRaWAN™ network.

Configuration file

The configuration file contains the basic parameters to establish a connection to The Things Network's MQTT broker and the influxdb database. The schema of this file is as follows:

[ttn]

    app_id =
    access_key =
    broker_url = eu1.cloud.thethings.network
    broker_port = 1883

[influxdb]

    user =
    password =
    database =
    measurement =

More than one configuration file can be added to establish different connections to the MQTT broker.

Setup

Clone the repository and create a new python virtual environment in which to install the ttn2influxdb package.

git clone https://github.com/AngelJMC/agriot-ttn-influxdb-connector
cd agriot-ttn-influxdb-connector
sudo python3 -m venv /opt/ttn2influxdb/pyenv
source /opt/ttn2influxdb/pyenv/bin/activate
sudo /opt/ttn2influxdb/pyenv/bin/python3 setup.py install

Copy the configuration file to the installation directory and add the configuration parameters.

# Copy configurations
sudo mkdir /opt/ttn2infuxdb/connections
sudo cp connections/config-example.ini /opt/ttn2influxdb/connections

# Edit configuration file
sudo nano /opt/ttn2influxdb/connections/config-example.ini

Configure program execution

sudo cp etc/systemd/ttn2influxdb.service /opt/ttn2influxdb
ln -sr /opt/ttn2influxdb/ttn2influxdb.service /usr/lib/systemd/system/

systemctl enable ttn2influxdb
systemctl start ttn2influxdb
systemctl status ttn2influxdb
journalctl -u ttn2influxdb -f
