An AI bot runs on a Meshtastic node with internet access and serves the entire mesh via a hub-and-spoke model. Network users send messages prefixed by a command marker (for example "!") to request information and the hub forwards queries to OpenAI's API. The hub runs a Python application with a GUI, processes incoming commands, manages response length to meet Meshtastic payload limits, and broadcasts AI-generated answers back across the mesh. Use cases include emergency medical or survival guidance, remote expedition support like plant identification and weather observations, field technical support, and outdoor education. The approach centralizes connectivity and avoids running large local models or complex routing.
Adrelien inMeshtastic -Bring ChatGPT AI to your Meshtastic mesh network with a simple Python bot. One internet connected node serves the whole mesh, enabling instant answers for survival, field ops, education, and more showcasing just how flexible and extensible Meshtastic can be. A few months back, I shared my experiments with sending voice messages over Meshtastic networks. That project got a lot of attention
and showed me just how eager the community is to push these mesh devices beyond their traditional boundaries. Today, I'm sharing something new: a complete AI bot system that brings GPT-powered responses directly to your mesh network. Emergency situations where you need instant medical or survival advice Remote expeditions where identifying plants, weather patterns, or troubleshooting equipment matters Technical support for field operations Educational applications for outdoor groups General knowledge access when you're off-grid but still connected to your mesh
