Welcome to the official ZTM Warsaw Integration wiki.
This integration brings real-time and timetable-based departure data from the City of Warsaw public transport API directly into Home Assistant. Track buses, trams, metro lines, night lines, and more β all from your dashboard or automations.
Powered by data from api.um.warszawa.pl β the official Warsaw public transport data provider.
