Hey everyone 
I built a custom Home Assistant integration for SL real-time departures. No Trafiklab account, no API key — uses SL’s open API and just works.
It has three sensors per stop:
• 
Next Departure — real-time countdown (“3 min”, “Nu”, “08:42”) with line, destination and delay as attributes
• 
Departures — list of upcoming trips, great for dashboard cards and TTS automations
• 
Status — normal / delayed / cancelled, with full history and per-departure issue details
Setup is a proper config flow:
Search for your stop by name, then pick the exact line + direction combinations you want to monitor (e.g. only Line 41 → Märsta, not everything at the stop). Configure how many departures to show and how far ahead to look.
Works for all SL transport modes — bus, metro/tunnelbana, pendeltåg, tram, and ferry.
Install via HACS (custom repository for now, submitting to the default catalog soon):
Or manual install: copy custom_components/sl/ to your HA config folder and restart.
Happy to hear feedback
