MeshMonitor v4.15.0 is a large feature release with no breaking changes. It reaches past Meshtastic and MeshCore to a third network, adds tools to plan and survey RF coverage, and tells you far more about what happened to each message you send.

Highlights below. The full list — every feature and fix — is in the CHANGELOG.

Reticulum support

MeshMonitor can now bridge to and monitor a Reticulum network: LXMF messaging, node position and telemetry, own-mode radio, and full topology / remote monitoring — the same views you already use for Meshtastic and MeshCore.

Plan and survey your RF

Two new tools answer "how far does this node reach?":

• Predictive coverage & Site Planner — model expected reach from a node or any point on the map using a Fresnel-zone and path-loss model, seeded from the node's live LoRa config, and draw it as a map layer.
• Passive network survey — reach, neighbours, and hop distribution computed entirely from traffic you already received, so it costs the mesh no extra airtime.

Know what happened to every message

Richer maps

• 3D terrain on the Mesh Map, Unified Map, and classic map, with 3D node markers that match the 2D view — color, type glyphs, age dimming, and clickable popups.
• GNSS satellite overlay — a live sky plot and DOP map for a node's fix.
• A satellite + labels hybrid tile option and a non-linear age filter that reaches out to week/month ranges.

And more

Prometheus metrics for Grafana and alerting, Node Status Messages, telemetry CSV export, an automation Run Now action, completed MeshBeacon + XEdDSA support, and MeshCore ⭐ favorites that sync to the firmware — plus a long list of fixes.

Upgrade the usual way. See the CHANGELOG for the complete notes.
