Texting When the Grid Isn't Available

Off-Grid Mesh Radio Workshop

Learn to build and deploy LoRa mesh radio networks that work without internet or cell service. These low-power devices communicate over miles of range, automatically relaying messages through the network to extend coverage across farms, forests, and neighborhoods.

What You'll Learn

  • Hardware setup - Working with affordable microcontrollers like ESP32 and Raspberry Pi Pico
  • Firmware flashing - Installing and updating mesh radio software on your devices
  • Network configuration - Setting up channels, encryption, and multi-device networks
  • Sensor integration - Connecting environmental sensors and sending data over the mesh
  • Custom functionality - Building modules for your specific monitoring needs

Applications

  • Farm monitoring - Track soil moisture, weather stations, and livestock across large properties without cellular coverage
  • Grid-down communications - Maintain text messaging and location sharing when power and internet are unavailable
  • Remote sensing - Monitor water levels, temperature, and other conditions in areas without infrastructure
  • Asset tracking - Keep tabs on equipment, vehicles, or animals across wide areas
  • Community networks - Build neighborhood communication systems independent of commercial infrastructure

How It Works

LoRa (Long Range) radio technology enables communication over several miles using minimal power. When multiple devices form a mesh network, messages automatically hop from node to node, extending range far beyond what a single radio could achieve. Each device can act as both an endpoint and a relay.

Workshop Details

Perfect for farmers, homesteaders, emergency preparedness enthusiasts, and anyone interested in resilient communications. No prior radio or electronics experience necessary - we'll start from the basics and have you sending messages by the end of the session.
