About
Blitzer.de is a Home Assistant integration that brings road reports from the Blitzer.de cloud service into Home Assistant. It watches either an area, set by a centre point and radius, or a route drawn along waypoints, and also supports a device tracker. Reports arrive as geo location entities for the map card, covering speed and other controls as well as traffic hazards such as tailbacks, accidents and roadworks. Controls and hazards each have their own update interval, whitelist and blacklist, and can be refreshed on demand through actions. Sensors report counts, and with TomTom as routing service also travel time, traffic delay and route length. A bundled blueprint and a dashboard card come with it, and setup is done in the UI.

Actions
- Refresh controlsImmediately fetch the latest controls for one Blitzer.de area, route or tracker, instead of waiting for its next scheduled poll. Returns the controls found. Controls only - "Refresh hazards" is the counterpart for hazards.Fields: Area, route or tracker
- Refresh hazardsImmediately fetch the latest hazards for one Blitzer.de area, route or tracker, instead of waiting for its next scheduled poll. Returns the hazards found. Hazards only - "Refresh controls" is the counterpart for controls.Fields: Area, route or tracker
- RefreshImmediately fetch the latest controls and hazards for one Blitzer.de area, route or tracker in a single pass, instead of waiting for its next scheduled poll. On a route this costs one request per point for both, where "Refresh controls" and "Refresh hazards" one after the other would cost two. Returns both lists, under controls and hazards.Fields: Area, route or tracker

From the README
Unofficial. Not affiliated with, endorsed by or supported by Blitzer.de. "Blitzer.de" and its symbols belong to their owner.
No longer developed. Its successor is TomTom: blitzer.de's reports built in, plus TomTom's own jams, closures, roadworks, accidents and road weather in more than 70 countries, Lufop speed cameras, a route planner on the card and 30 languages. Blitzer.de keeps working as it is, but gets no new features.
