I always wanted a Wiener-Linien-LED-style card for my dashboard, so I wrote an integration for it. If anyone else has always wanted one — you can download it here:

Comes with:
- One sensor per stop, state = countdown to the next departure. Full board in attributes (line, direction, platform, delay, step-free, …).
- Service disruption + elevator-outage alerts filtered to the lines you track.
- Two bundled Lovelace cards — a modern multi-stop board and the retro LED-display I actually wanted.
- Config flow only — no YAML, no API key, no RBL lookups.
Feedback, bug reports and feature ideas very welcome!
