About
Blitzortung is a Home Assistant integration that reports real time lightning strikes near a chosen location using Blitzortung.org data. It adds sensors for the distance and azimuth of nearby strikes and a counter of strikes. It also emits geo location events for strikes, which show on the map. Data reaches Home Assistant through a public MQTT server run for this component, which reduces the data sent to clients compared with a direct connection to Blitzortung servers. The location can be fixed coordinates, which default to the home location, or a device tracker, person or zone entity that the integration follows. Options cover the detection radius, the time window for tracked strikes and the maximum number of tracked strikes, and setting that maximum to zero turns off the strike entities while the sensors keep working. Setup is done in the UI.

From the README
Blitzortung.org is a worldwide, real time, community collaborative lightning location network. This component uses Blitzortung data and provides real time notifications about lightning strikes in a given area (by default within 100km radius of your home). Data is served through a public MQTT server (dedicated to serve requests for this component) - thanks to geohash-based topics and some other optimizations, it greatly reduces amount of data sent to clients comparing to direct websocket connection to Blitzortung servers (it is also required by Blitzortung data usage policy - third party apps must use their own servers to server data for their own clients).
- distance and azimuth sensors of lightning strikes nearby
- counter of lightning strikes
- emits geo_location events for lightning strikes (visible on the map)
- data is realtime, with average delay of few seconds
