I am about to try an "MVP open alpha" for https://sensetif.net, a capture, storage, visualization platform for IoT streaming data.

Visualization by Grafana. Storage by Cassandra.

Create Projects with Subsystems that have Datapoints.

It can poll from http(s) endpoints with json or xml data, OR The Things Network (ver 3), down to every 5 minutes.

What do YOU think?
