2026-01-15 + +### Added + +#### Background Polling System +- **Continuous automatic device polling** - Background service that continuously polls configured devices +- **Per-device configurable intervals** - Each device can have custom polling interval (10-3600 seconds, default 60) +- **Automatic offline detection** - Devices automatically marked unreachable after 3 consecutive failures +- **Reachability tracking** - Database fields track device health with failure counters and error messages +- **Dynamic sleep scheduling** - Polling service adjusts sleep intervals based on device configurations +- **Graceful lifecycle management** - Background poller starts on application startup and stops cleanly on shutdown + +#### New API Endpoints +- `GET /api/nl43/{unit_id}/polling/config` - Get device polling configuration +- `PUT /api/nl43/{unit_id}/polling/config` -

no code duplication +- Respects existing 1-second rate limiting per device +- Efficient resource usage - skips work when no devices configured +- WebSocket streaming remains unaffected - separate real-time data path + +#### Default Behavior +- Existing devices automatically get 60-second polling interval +- Existing status records default to `is_reachable=true` +- Migration is additive-only - no data loss +- Polling can be disabled per-device via `poll_enabled=false` + +#### Recommended Intervals +- Critical monitoring: 30 seconds +- Normal monitoring: 60 seconds (default) +- Battery conservation: 300 seconds (5 minutes) +- Development/testing: 10 seconds (minimum allowed) + +### Migration Notes + +To upgrade from v0.1.x to v0.2.0: + +1. **Stop the service** (if running): + ```bash + docker compose down slmm + # OR + # Stop your uvicorn process + ``` + +2. **Update code**: + ```bash + git pull + # OR copy new files + ``` + +3. **Run migration**: + ```bash + cd slmm + python3 migrate_add_polling_fields.py + ``` + +4. **Restart service**: + ```bash + docker compose up -d --build slmm + # OR + uvicorn app.main:app --host 0.0.0.0 --port 8100 + ``` + +5. **Verify polling is active**: + ```bash + curl http://localhost:8100/api/nl43/_polling/status | jq '.' + ``` + +You should see `"poller_running": true` and all configured devices listed. + +### Breaking Changes +None.
