My node is flooding the channel with repeated messages If you notice unusually high channel utilization, see the same message appear many times in quick succession, or other mesh users report your node is hammering the airwaves, your node may be contributing t...

My Meshtastic node and MeshCore node cannot communicate This is one of the most common points of confusion for new mesh users: both Meshtastic and MeshCore run on similar LoRa hardware, operate in the same 915 MHz band, and can even share the same physical cha...

RF Interference Is Affecting My Node — How to Diagnose It LoRa spread-spectrum modulation gives it excellent resistance to narrowband interference, but it is not immune. If your node is experiencing unexplained packet loss, poor RSSI from nearby nodes, or erra...

What Is the Difference Between a Repeater and Room Client in MeshCore? MeshCore ships two primary firmware variants for end-user nodes, each optimized for a different role in the network. Choosing the wrong one is a common source of confusion. This page explai...

How Do I Connect to a MeshCore Room Server From the App? A MeshCore room server stores messages for offline nodes and enables larger-group conversations that persist beyond the RF range of any single transmission. Connecting to one from the MeshCore app is str...

Can I Run MeshCore and Meshtastic Simultaneously on the Same Hardware? The short answer is: no. You can only run one firmware at a time on a given LoRa node. However, there are practical workarounds if you need coverage of both protocols at one location. Why ...

Day 1: Getting Your Node Online Welcome to the mesh. Today goal is simple: get your node powered on, flashed with current firmware, and visible to other nodes in your area. Follow this checklist from top to bottom. If you hit a snag, the troubleshooting notes ...

Day 2–7: Exploring the Mesh Now that your node is online, spend the rest of your first week learning what the mesh can do and how to read what it is telling you. Each day below has a focused activity — nothing takes more than 15–20 minutes. Day 2: Send your f...

Understanding What You Are Seeing in the App The Meshtastic app surface area can seem dense at first. This page decodes the most important numbers and indicators you will encounter day-to-day, so you can read the mesh like a map instead of a wall of jargon. S...

Understanding how Meshtastic actually routes messages helps you make better configuration decisions and troubleshoot problems faster. Flooding: The Core Mechanism Meshtastic uses a flooding broadcast approach to message delivery. When you send a message: Y...

Understanding how Meshtastic nodes are identified helps you interpret the node list, configure direct messaging, and troubleshoot network issues. Node ID Format Every Meshtastic node has a unique 32-bit node ID derived from its hardware MAC address. The ID is...

When you get a new Meshtastic node, running through a standard configuration checklist ensures it's properly set up for your network before deployment. This guide covers every setting that matters for a production deployment. Step 1: Flash Latest Stable Firmw...

Infrastructure nodes (routers, backbone repeaters) require additional configuration beyond the defaults to operate efficiently and reliably in a production network. Power Management Infrastructure nodes should never sleep — they need to receive and relay traf...

The Meshtastic Python CLI provides the most comprehensive access to node configuration and data. This reference covers all major command categories. Installation pip install meshtastic # or for latest development version: pip install meshtastic --pre Connect...

Meshtastic's power management settings control how your node balances battery life against responsiveness. Understanding these settings is essential for field deployments and battery-powered infrastructure. Key Power Settings SettingDefaultDescription power...

Overview Integrating Meshtastic into Home Assistant unlocks powerful home automation possibilities: track family members on a mesh map, get alerts when a node goes offline, and trigger smart-home actions based on mesh events. The integration uses MQTT as the t...

A yagi antenna provides significant directional gain for point-to-point links — ideal for connecting two backbone nodes across a valley, mountain, or city. Building your own 915 MHz yagi is a rewarding project that costs $10-20 in materials vs. $50-150 for a c...

A collinear vertical antenna provides omnidirectional coverage with moderate gain (3-6 dBd) — a significant improvement over the stock rubber duck antennas included with most LoRa boards. A 3-element collinear is straightforward to build with basic tools. How...
