About DFTZ
Distributed Field Technology Zone - an experimental mesh network platform for remote monitoring and control.
What This Is
DFTZ is a hobby project exploring mesh networking for remote sensor monitoring. It uses Meshtastic LoRa radios to create a self-healing mesh network.
The dashboard you see here connects to a gateway node that bridges mesh traffic to MQTT, storing telemetry in InfluxDB and displaying it via this Next.js application.
Hardware designs are works in progress. Nothing is for sale. This is a personal project shared publicly for anyone interested in similar applications.
Technology Stack
Meshtastic
Open-source firmware for LoRa radios. Handles mesh routing, encryption, and device management.
meshtastic.org →MQTT + InfluxDB
Gateway publishes to Mosquitto MQTT broker. Telemetry stored in InfluxDB for time-series queries.
Next.js + PostgreSQL
Web dashboard built with Next.js. User accounts and node metadata stored in PostgreSQL.
