Car park availability

ha-australia-carpark brings car park data from eight Australian sources into Home Assistant: Adelaide’s UPark, Transport for NSW, Brisbane City Council, Wilson Parking, and the cities of Sydney, Perth, Canberra and Hobart.

For each car park that publishes something it creates sensors for spaces free, occupancy and total spaces, and a binary sensor for whether any space is available. It also totals an area: spaces free, total and occupied, and the number of car parks tracked. The area can be a radius around home, an existing zone, or the whole country.

Each source is a provider behind a common interface, and they are queried in parallel, so one source failing does not affect the others.

The sources differ a great deal in what they publish. That is the subject of What Australian car park data actually contains.
