Meshtastic Turns Off-Grid Mesh Into Home Assistant Alarm

Hackaday reports on a project where Meshtastic is used beyond simple text messaging: an off-grid, long-range mesh connects a shed alarm to Home Assistant via Heltec ESP32 LoRa modules. A remote node watches an infrared beam and publishes alerts over Meshtastic, while a second module bridges to Wi‑Fi and MQTT for Home Assistant integration, showcasing Meshtastic’s potential for distributed sensing and automation beyond chat."
