ttn2influxdb

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.
