Since today, the LoRa Server project integrates with InfluxDB (open-source time series database). On top of InfluxDB you can use Grafana for creating dashboards (open-source analytics and alerting platform).

When using the CayenneLPP encoding, LoRa Server can directly decode the sensor data :-) The only thing you need to do is when creating an application (in LoRa App Server) is to select the Cayenne LPP codec and create an InfluxDB application integration.

I've created a couple of examples for the PyTracker and PySense which you can find here: https://github.com/brocaar/pycom-examples

More about this feature can be found here: https://forum.loraserver.io/t/lora-app-server-influxdb-integration-with-grafana/1318

LoRa Server documentation (and downloads) can be found here: https://www.loraserver.io

I hope this will be helpful!
