Project Overview
In an increasingly Wi-Fi-dependent world, resilient long-range radio networks are still often overlooked. For quite a while until now I have been fascinated by the idea of offgrid communication. A small entry level project with Meshtastic radios would be the perfect opportunity to get hands-on experience in this field. This project focuses on a fully autonomous Meshtastic router node designed to operate off-grid and strengthen decentralized communication infrastructure.
The system is built around a LilyGo T-Beam Supreme and configured as a dedicated LoRa router, continuously relaying traffic across the mesh. By running entirely on a 12V bettery continuesly charged by a solar panel, the node can remain deployed without sun for upto 5 days and more than a week on power-saving mode.
To improve visibility and accessibility, the router is also connected to MQTT, enabling telemetry and position data to be forwarded to internet-based tools. This creates a practical bridge between low-power radio networking and live web-based monitoring.
Key Features
Dedicated Meshtastic router role for reliable packet forwarding
MQTT integration with position broadcasting for real-time data streaming
Long-range LoRa communication with minimal power consumption
Autonomous, solar-powered operation. Designed for off-grid and remote deployments
Humidity, temperature, and pressure sensors for telemetry packets
Installed on the campus of Eindhoven University of Technology to expand local coverage and support portable node testing
Live Mesh Map
This node publishes telemetry and position data through MQTT, making it visible on a public mesh map in real time. The live map provides a simple way to monitor presence, placement, and coverage within the wider network.
