MeshMonitor v4.9.1

A small follow-up to v4.9.0 that adds voltage-based low-battery alerts for MeshCore companions and a neighbour-averaged source for the airtime cutoff, and fixes two regressions: MQTT broker sources showing no nodes on the dashboard/map, and the Auto Traceroute match-list preview ignoring its "Last Heard Within" and "Hop Range" filters.

Features

• MeshCore low-battery alerts (voltage-based) (#3332) — Low-battery notifications now work for MeshCore sources. MeshCore devices report battery as a voltage (mV) rather than a 0–100 percentage, so a new per-user voltage threshold (default 3300 mV) is compared against each monitored node's batteryMv. The Notifications settings expose both thresholds — percentage for Meshtastic, mV for MeshCore — and the monitored-node picker now lists all MeshCore nodes (not just those with a GPS fix). Resolves #3331.
• Airtime cutoff — neighbour-averaged source (#3328) — The airtime-utilization cutoff (Automation page) can now measure Channel Utilization from nearby infrastructure instead of the local node. In "Nearby infrastructure" mode it averages the Channel Utilization of the 3 strongest-RSSI directly-heard (0-hop) router/repeater nodes — useful when a well-placed node under-reports the wider mesh. The live banner shows which source is in use and how many neighbours were sampled.

Bug Fixes

• MQTT broker source dashboard/map showed no nodes (#3333) — MqttBrokerManager was missing the getAllNodesAsync / getConnectionStatus / getDeviceConfig methods that the consolidated /api/poll endpoint calls, so those endpoints returned HTTP 500 for mqtt_broker sources and the dashboard/map received no node data despite positions being ingested and stored correctly. The broker manager now implements the same DB-backed read methods as MqttBridgeManager.
• Auto Traceroute match-list preview ignored filters (#3330) — The Auto Traceroute match-list preview now honours the "Last Heard Within" and "Hop Range" filters instead of showing every node. Resolves #3329.

Issues Resolved

• #3331 — low-battery alerts for MeshCore
• #3329 — Auto Traceroute "Last Heard Within" and "Hop Range" filters not affecting the match list
