Mesh System Pager
April 06, 2026
A small daemon that reads live system metrics from a Linux machine and broadcasts them over a Meshtastic LoRa mesh network, one message per category, every 60 seconds.
Three reports are sent in sequence on each cycle: CPU (per-core usage, temperature sensors, uptime), RAM (used/total, swap, top 5 processes by memory), and network (RX/TX rates, totals, active interface IPs, disk usage). Each report is packed into a compact pipe-delimited string and truncated to fit within Meshtastic’s 228-byte text payload limit.
The tool connects via serial to a locally attached Meshtastic device, then loops indefinitely. Signal handlers for SIGINT and SIGTERM close the interface cleanly on exit.
The use case is remote monitoring of a machine, such as a home server, a Raspberry Pi in the field, or any headless box. It does not need Wi-Fi, cellular, or an internet connection. As long as a Meshtastic node is within LoRa range, you can pull stats from anywhere.
