…diefan#33) - Connection registry routes MQTT commands to correct camera by baby UID - Manager registry tracks websocket connection managers per baby - Global MQTT handler registration (moved from per-connection to app-level) - Handler signatures now include babyUID for proper multi-camera routing - ForceReconnect() with cooldown skip for failed command recovery - Pending retry queue replays failed commands after reconnection - New env vars: NANIT_MQTT_RESET_WHEN_FAILED, NANIT_WEBSOCKET_TIMEOUT
- Extend protobuf schema with brightness (Settings), duration/soundtrack (Playback) - Add MQTT subscriptions for brightness, playback (start/stop), and volume commands - Route all commands through connection registry for multi-camera support - JSON payloads for brightness, playback, and volume topics
- Publish discovery configs on MQTT connect for each registered baby - Sensors: temperature, humidity, last motion/sound, stream URL - Binary sensors: night, stream active, camera online, crying, standing, left bed, alert zone, temp/humidity/breathing alerts, low battery, asleep, in bed - Switches: night light, standby mode - Gated behind NANIT_MQTT_DISCOVERY env var (default true when MQTT enabled)
- New notification package with event poller, deduplication, and publisher - Polls Nanit REST API for events with jitter and exponential backoff - Publishes events to MQTT: motion, sound, crying, standing, left bed, alert zone, temperature/humidity/breathing alerts, camera online/offline - New env vars: NANIT_NOTIFICATIONS_ENABLED, NANIT_NOTIFICATIONS_POLL_INTERVAL, NANIT_NOTIFICATIONS_MAX_BACKOFF
