The fastest way to grow a mesh community is to let people experience the network firsthand. Events and demonstrations convert curious bystanders into active participants in a way that no amount of documentation can match. The Mesh Meetup Format A mesh meetup r...

A community mesh network that isn't documented is one resignation or one hardware failure away from being unrecoverable. Documentation is not overhead - it's the infrastructure that makes the physical infrastructure maintainable. What to Document For every per...

A Meshtastic network that works well with five nodes may behave poorly at fifty. Managing growth proactively - rather than reacting after congestion degrades performance - is what separates a durable community network from one that works great until it doesn't...

Meshtastic's MQTT module extends a LoRa mesh network over the internet by bridging packets between the radio air interface and an MQTT message broker. A gateway node - a Meshtastic device with a working Wi-Fi or Ethernet connection - uplinks packets it hears o...

Any Meshtastic device with a direct internet connection can act as an MQTT gateway. This includes ESP32-based boards with onboard Wi-Fi (such as the LILYGO T-Beam or Heltec WiFi LoRa 32) and the nRF52-based RAK4631 paired with the RAK13800 Ethernet module. A n...

Eclipse Mosquitto is the de-facto standard open-source MQTT broker, widely used with Meshtastic for private mesh deployments. This guide installs Mosquitto on a Raspberry Pi or Ubuntu/Debian server, secures it with TLS, adds authentication, and optionally brid...

Node-RED is a browser-based visual programming tool built on Node.js, ideal for wiring together MQTT data streams from Meshtastic with downstream services such as dashboards, databases, and messaging platforms. This page covers installing Node-RED, subscribing...

If you have ever used Wi-Fi at home, you are already familiar with the most common type of wireless network: the star topology. Every device in your house - your phone, your laptop, your smart TV - talks to one central access point (your router), and the route...

LoRa stands for Long Range. It is a wireless radio modulation technique invented by a French startup called Cycleo and acquired by Semtech in 2012. LoRa chips appear in millions of devices worldwide today, from smart utility meters to wildlife trackers to comm...

One of the most common sources of confusion when starting out is the alphabet soup of acronyms: LoRa, LoRaWAN, Meshtastic, MeshCore. People use them interchangeably, but they are four very different things operating at four different layers. This page explains...

Nearly all LoRa mesh devices sold for North America operate in the 915 MHz ISM band (902 - 928 MHz). (A few 433 MHz LoRa devices also exist and are usable here, but they are uncommon.) Understanding what that means - and what the rules are - will help you choo...

This guide will take you from zero to sending a LoRa mesh message on Meshtastic, step by step. No prior RF or networking experience is required. If you get stuck, the What to Check sections at the end will help you diagnose the most common problems. Step 1: B...

MeshCore is a newer peer-to-peer LoRa mesh platform that differs from Meshtastic in some important ways. This guide walks you through buying hardware, flashing firmware, and sending your first message - including a plain-language explanation of what makes Mesh...

Having a single node transmitting into the void is technically functional, but the real magic of a mesh network only appears when you are connected to other people. This page explains how to find out whether there is already an active mesh in your area, what t...
