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 c...

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 aut...

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 G...

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. ...

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...

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 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 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...

Every Meshtastic channel uses AES-256-CTR symmetric encryption. Understanding how this works — and what it protects against — is essential for deploying Meshtastic for any sensitive use. How Channel Encryption Works A channel is defined by two parameters: its...

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...

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...

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...

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...
