Reverse geocoding generates an address from a latitude and longitude of device tracker.

Note: Home Assistant's Companion App provides a built-in Geocoded Location sensor that performs reverse geocoding on-device using Apple/Google services. This integration differs by using OpenStreetMap Nominatim server-side, which gives you full control over the output format via Jinja2 templates, consistent results across all device types, richer address detail from OSM data, and works with any device_tracker entity -- not just Companion App devices. For example, OSM data includes nearby point-of-interest names like store names (e.g. "Lidl, Piątkowska 64, Winiary, Poznań") that native geocoding typically omits.

Inspired by GoogleGeocode-HASS.
