MeshMonitor v4.15.0

A large feature release with no breaking changes. MeshMonitor 4.15 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 every message you send. Reticulum joins as a first-class monitored network — LXMF messaging, position and telemetry, own-mode radio, and full topology / remote monitoring. A new predictive RF coverage model and Site Planner estimate a node's reach from a Fresnel-zone + path-loss model, while a passive network survey derives reach, neighbours, and hop distribution from traffic you already received. Click any message for Delivery Details: the exact routing result, a per-message event timeline, and a Heard-By correlation of which nodes relayed it. Maps gain 3D terrain across every surface with markers that match the 2D view, a GNSS satellite overlay, and a hybrid satellite tile. Rounding it out: a Prometheus metrics endpoint, Node Status Messages, telemetry CSV export, completed MeshBeacon + XEdDSA support, and a long list of fixes.

Full notes live in the CHANGELOG.
