MeshMonitor v4.9.0

A feature release focused on keeping your mesh healthy and your automations polite. v4.9.0 adds low-battery alerts for monitored nodes and an airtime-utilization cutoff that automatically pauses bot automations (auto-traceroute, auto-announce, timers, and more) whenever the connected node's Channel Utilization climbs above a threshold — so bots back off while real people are using the channel and resume once it quiets down. The Device Info telemetry graphs gain a time-range selector (15m–7d) with averaging that scales correctly across long windows on every database backend. Automation templates pick up a new {LAST_HOP} variable that resolves the last relay node. The per-source ignore list is now authoritative, re-applying the ignore flag (and re-pushing it to the radio) when a device drops it. On the fixes side, MQTT environment telemetry is visible again (keys now match serial ingestion, with a migration to repair history), and a PostgreSQL GROUP BY bug in the new averaged telemetry query — which returned HTTP 500 on Postgres deployments — was caught by the release system tests and fixed, with a Postgres regression test added to standard CI so it can't recur.

Features

• Low-battery alerts for monitored nodes (#3310, closes #3305) — notify via Apprise / Web Push / Desktop when a monitored node's battery drops below a configurable threshold.
• Airtime-utilization cutoff (#3311) — a "Cutoff Airtime Utilization Threshold" on the Automation page pauses all transmitting automations while the mesh is busy; live status banner, manual sends never blocked.
• Telemetry time-range selector + scalable averaging (#3312) — 15m–7d window selector on the Device Info graphs, remembered per browser, with averaging that no longer truncates long windows.
• {LAST_HOP} automation variable (#3320, closes #3318) — resolves the last relay node (short name → hex byte → unknown) in autoresponder/auto-ack templates.
• Ignored-node auto-reapply (#3313, closes #2601) — the per-source ignore list is authoritative; re-applies and re-pushes the ignore flag when a device's node DB drops it.
• MeshCore chat date separators (#3319, closes #3316) — separators between messages from different days.

Bug Fixes

• Averaged telemetry graph query on PostgreSQL (#3327) — fixed an HTTP 500 from GET /api/telemetry/:nodeId on Postgres (GROUP BY functional-dependency error); added a Postgres regression test to pr-tests CI.
• MQTT telemetry key normalization (#3315, closes #3314) — MQTT environment metrics now use the canonical keys serial uses, with a migration to repair existing rows, so they show in the graphs.
• Unified source node count (#3323, closes #3321) — include MeshCore nodes in the count.
• Apprise configuration (#3325, closes #3324) — fixed a UNIQUE constraint error when configuring Apprise for a second source.
• MeshCore packet-log timestamps (#3317) — widened meshcore_packet_log timestamp/createdAt to BIGINT.
• API rate limiter (#3309, closes #3308) — exempt RFC 1918 / loopback IPs so local/reverse-proxy traffic isn't throttled.
• PWA chat input (#3307) — removed dead space below the chat input in the installed PWA.
• MeshCore sidebar icons (#3306) — use lucide icons matching the MQTT/Meshtastic styling.
