Troubleshooting

• Verify the container health endpoint: curl http://localhost:${PORT:-3000}/health.
• Subscribe to the configured topic tree: mosquitto_sub -t '<topic>/#' -v.
• Confirm broker credentials and network reachability from inside the container.
• Commands are intentionally non-retained and are cleared after handling. Re-publish a valid payload if needed.
• Never paste tokens, cloud sessions, or passwords into issues or logs.
