Two efforts that landed together because the v2 topic work extends tables the health-telemetry effort added days earlier in the same files/functions, making them impractical to separate cleanly: Health/diagnostics telemetry (schema, Jul 13-17): - New Postgres tables: device_alert_events, device_boot_events, device_ping_samples, device_diagnostics_reports, plus a `source` column on device_logs to distinguish log origins - Query/service layer in pg_mqtt.py and database/__init__.py for inserting and listing this history, plus a "latest metrics" endpoint combining most-recent diagnostics + ping RTT per device - mqtt/router.py gains list endpoints for alert/boot/ping/diagnostics history, consumed by the upcoming Health tab MQTT v2 topic migration (Sep 21): - Heartbeat payload flattened per vesper_mqtt_topic_spec_v2.md, adding rssi/free_heap/state/ok fields - Command replies move to control/ack, device-initiated events to control/reports; mqtt/client.py subscribes to the new topic set and runs a ping_loop (wired up in main.py) for RTT sampling - mqtt/logger.py and pg_mqtt.py updated to parse and persist the new payload shape alongside the legacy fields for backwards compatibility Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

"""device_alert_events
|
|
|
|
Adds an insert-only history log of device alert transitions (WARNING/CRITICAL/
|
|
FAILED only — CLEARED is not logged here). device_alerts remains the current-
|
|
state table and is untouched; this is purely additive, used to answer "when
|
|
was the most recent issue on this device" even after it has been resolved.
|
|
|
|
Also adds an optional rssi column to heartbeats, for a signal-strength
|
|
indicator once firmware starts reporting it on the heartbeat payload.
