Meshstellar ✨ - Monitor your Meshtastic constellation

Welcome to Meshstellar, an open-source tool designed for monitoring and analyzing your local Meshtastic network. Meshtastic is a powerful platform that uses long-range, low-power radio mesh networking, ideal for communication beyond the reach of traditional connectivity. Meshstellar aims to complement this by offering insights into network traffic and node health, helping you keep your network running smoothly.

Features

• Traffic Monitoring: Track the flow of packets within your network, including their origin, destination, and payload, to better understand network activity.
• Health Analysis: View critical metrics such as battery levels, signal strength, and channel utilization for each node to quickly spot and resolve potential issues.
• Node Overview: Gain a quick summary of all nodes in your network, including their status and location, to maintain a clear view of your network's layout.
• Neighbor Insights: Understand how nodes are interconnected by using Neighborinfo packets.
• Device Metrics: Access important device performance indicators, including voltage and airtime utilization, to make informed decisions about node management.
• Off-grid support: The application can run fully local (no external resources).

Technical overview

Meshstellar is a straightforward project aimed at Meshtastic network users. It's written in Rust and stores data in a SQLite database. Its frontend tries to use as little JavaScript as possible, and uses HTMX and _hyperscript.

How it works

Meshstellar listens for data from Meshtastic devices sent over MQTT, like messages or node stats. This data, packed in Protocol Buffers, is then decoded and stored in a SQLite database (which by design stays as close to the source data as possible). It's a simple approach to log and keep track of what's happening in your network.

Prerequisites

To run Meshstellar you need a Linux or Windows system and a MQTT broker to connect to. The Meshtastic node you want to monitor needs to be configured to uplink the mesh packets to this broker.

Node configuration

Make sure the node is configured to send data to the MQTT broker and 'Encryption Enabled' is turned off so Meshstellar can parse the unencrypted packets.

Configuration

There are a few configuration file examples in this repository.

On Windows you can configure it using the meshstellar.toml file (rename it from meshstellar.toml.example and put it in the same directory as the .exe file).

On Linux / Docker it's easiest to configure it using environment variables (see .env.example for a list of environment variables you can configure). However it is also possible to use the file-based configuration.

The following locations are checked for the file-based configuration:

1. meshstellar.toml in the current working directory
2. $XDG_CONFIG_HOME/meshstellar/meshstellar.toml or %APPDATA%/meshstellar/meshstellar.toml on Windows
3. $HOME/.meshstellar.toml
4. /etc/meshstellar/meshstellar.toml

How to run

Windows

Make sure the configuration (the meshtastic.toml file) is updated and saved in the same directory as the meshstellar.exe file. Double click the .exe to start meshstellar.

Use docker-compose

See docker-compose.yml.example for an example deployment. This is a more robust deployment running separate containers for the MQTT connection, packet parsing and web interface.

Use docker

It's also possible to use docker directly to try out Meshstellar. This setup uses a single docker container to run Meshstellar. See .env.example for all environment variables that can be set.

docker volume create meshstellar_data
docker run \
  --name meshstellar \
  --user 65532:65532 \
  --restart on-failure \
  -p 3000:3000 \
  -e MESHSTELLAR_HTTP_ADDR='0.0.0.0:3000' \
  -e MESHSTELLAR_DATABASE_URL="sqlite:///home/meshstellar/meshstellar.db?mode=rwc" \
  -e MESHSTELLAR_MQTT_HOST="mqtt-host-here" \
  -e MESHSTELLAR_MQTT_AUTH="true" \
  -e MESHSTELLAR_MQTT_USERNAME="username" \
  -e MESHSTELLAR_MQTT_PASSWORD="password" \
  -e MESHSTELLAR_MQTT_TOPIC="msh/#" \
  -v meshstellar_data:/home/meshstellar:z \
  ghcr.io/jurriaan/meshstellar:latest

Manually on command line

Meshstellar can be run in different modes based on the command-line argument provided when starting the application.

The simplest mode is the all mode, which starts the MQTT processing and web server in a single process:

meshstellar [all]

A more robust setup has separate processes for the mqtt ingestion, packet importing and web service functionality.

meshstellar mqtt
meshstellar import
meshstellar web
