Reading Network Statistics in the Meshtastic App
Reading Network Statistics in the Meshtastic App Understanding what your Meshtastic network is actually doing requires knowing how to read the statistics the app surfaces. The mobile app (Android and iOS) and the web client all expose channel utilization, air...
Using the Meshtastic Python CLI for Diagnostics
The Meshtastic Python package ships both a library and a command-line interface (CLI). The CLI is the fastest way to interrogate a connected node, export its configuration, watch live packet traffic, and run one-off diagnostic commands from a laptop. This page...
Mesh Topology and Path Analysis
Knowing how your messages travel through the mesh is essential for identifying bottleneck nodes, optimizing relay placement, and diagnosing delivery failures. Meshtastic exposes hop-count information in every received packet, and community tools like meshmap.n...
Common Network Problems and Solutions
Common Network Problems and Solutions Meshtastic networks are remarkably self-organizing, but they are not self-diagnosing. When the mesh stops working well - messages drop, nodes disappear, delivery becomes unreliable - there are a small number of root cause...
Getting Started with the Meshtastic Python Library
The Meshtastic Python library (meshtastic on PyPI) provides a clean API for connecting to Meshtastic devices, reading their state, sending messages, and reacting to received packets via callbacks. This page covers installation, all three connection methods (se...
Automating Meshtastic: Practical Scripts
The Meshtastic Python library enables powerful automation workflows. This page provides four complete, ready-to-use scripts: a position logger, a message forwarder to Telegram, a battery monitor with alerts, and an automated network health reporter. Each scrip...
Meshtastic Python API Reference
This page documents the key classes, methods, and patterns of the Meshtastic Python library. It covers the four interface classes, the event system, protobuf message types, and error handling. Refer to the library's source on GitHub for the full method signatu...
Telemetry Module: Device, Environment, and Power
The Telemetry module broadcasts sensor data from your node across the mesh - battery voltage, temperature, humidity, barometric pressure, and more. Other nodes receive this data and display it in the app, and it can be forwarded to external systems via MQTT. ...
Store and Forward Module
The Store and Forward module lets a designated node buffer messages for clients that were offline when a message was sent. When the offline client reconnects to the mesh, it can request the message history and receive messages it missed. How Store and Forward...
Range Test Module
The Range Test module automates signal strength measurement for deployment validation - letting you map exactly where in your coverage area packets arrive successfully, and at what SNR and RSSI values. What the Range Test Module Does Range Test operates as a ...
External Notification and Canned Messages
External Notification Module The External Notification module triggers a visual or audio alert on the node hardware when a message is received - useful for heads-up awareness without constantly watching a screen. Configuration meshtastic --set external_notifi...
Serial, MQTT, and Ambient Light Modules
Serial Module The Serial module lets external hardware send and receive Meshtastic messages over a UART serial connection - enabling integration with microcontrollers, GPS units, custom sensors, and computer software. Modes of Operation ModeDescriptionUse Ca...
PKC Direct Messaging (v2.5+)
Meshtastic v2.5 introduced Public Key Cryptography (PKC) encrypted direct messages - a significant security upgrade that makes DMs genuinely end-to-end encrypted rather than just channel-scoped. Note on terminology: This feature is officially called "PKC Dire...
Meshtastic Managed Mode and Admin Channels
For deployed infrastructure nodes - community repeaters, fixed gateways - you want to prevent unauthorized configuration changes while still being able to administer the node remotely. Meshtastic provides two tools for this: Managed Mode and Admin Channels. M...

Why isn't my GPS getting a fix?
GPS fix time expectations Getting a GPS fix takes time - particularly on a cold start (first power-on or after being stored). Under normal outdoor conditions: ConditionExpected fix time Cold start, outdoors, clear sky30 seconds - 5 minutes Warm start (powere...
Can I use my node inside my house or vehicle?
Short Answer Yes, with significant range reduction. Interior use is practical for connecting to a nearby outdoor repeater or for testing. It's not suitable as a repeater location. What Signal Loss to Expect LocationTypical Signal LossNotes Near a window, wo...
Ski Patrol and Mountain Safety
Why Ski Resorts Are a Communications Challenge A modern ski resort is one of the most punishing RF environments imaginable. Hundreds of vertical metres of complex terrain create deep shadow zones behind ridgelines, cliff bands, and the thick concrete-and-st...
