| - | --- | + | The Stream Deck talks to these entities over the Home Assistant REST API. It runs as a container on the same Pi as the API, and it mirrors Home Assistant, so switching a preset from either place updates both. |
| - | ## Completed Projects | + | **Troubleshooting: |
| - | | + | If the sign shows "no upcoming arrivals" |
| + | |||
| + | 1. Query the API for a broken route and for a route on the same feed the sign never asks for. If the second one works, the data is fine and something is caching empty results. | ||
| + | 2. Check for a stuck feed sync: `SELECT feed_code, locked_at, now() - locked_at FROM sync_lock;` A row older than a few hours is stale, and it blocks that feed from syncing again until you clear it. | ||
| + | 3. Check the data has not aged out: `SELECT feed_code, min(start_date), | ||
| + | 4. To force a sync: `docker exec transit-tracker-api-api-1 node dist/cli sync --force --feed < | ||
| + | 5. A sync run this way is invisible to the running API for up to 12 hours, because schedule results are cached in memory as well as in Redis. Restart the API container to pick them up: `docker restart transit-tracker-api-api-1` | ||

| + | ### ESP32 Transit Tracker (WhereTrain) | ||
| + | |||
| + | |||
| + | ![](/: | ||
| + | |||
| + | A real-time transit tracker that displays Sound Transit Link Light Rail train positions on a physical LED map. The system uses an ESP32-S3 microcontroller to poll live transit data and render animated train movements across an addressable LED strip. Originally designed for /dev/hack Seattle. | ||

| + | **Hardware: | ||
| + | |||
| + | - **Microcontroller**: | ||
| + | - **Display**: | ||
| + | - **PCB**: JLCPCB-manufactured, | ||
| + | |||
| + | **How it works:** | ||
| + | |||
| + | - Polls the [OneBusAway API](https:// | ||
| + | - Renders smooth crossfade animations showing train movements between stops on the LED strip | ||
| + | - API key can be requested from Sound Transit at `oba_api_key@soundtransit.org` | ||
