I wrote a telegraf plugin that takes the UDP data and outputs it in a format that can be ingested by the telgraf general-purpose agent. Telegraf lets you route the data to influxdb, mqtt, sql, or a bunch of other places. It’s written in go and runs pretty reliably on most operating systems. It’s free, and so is my plug-in, if anybody is interested.
My setup is tempest_udp → telegraf → influxdb → grafana. The graph above (if it pasted correctly) shows a severe thunderstorm that just blasted through. The X axis is the time, Y is the distance to the strike event, and the color intensity indicates how many strikes. Around 8:00 PM I had 27 strikes within 1 kilometer of my house.
