RAK Gateway

Working

The bridge between your mesh network and the internet. Listens to all mesh traffic and forwards it to the cloud via WiFi, so you can see your data on the dashboard from anywhere.

Without a gateway, data stays local to the mesh. With one, everything flows to your dashboard, database, and automations.

MQTT Topics

Meshtastic publishes to standard MQTT topics. The gateway service subscribes and processes incoming messages.

msh/+/json/+/!nodeId

JSON-formatted messages from specific node

msh/+/json/LongFast/!nodeId

Channel messages with telemetry

Terminal
$ mosquitto_sub -t "msh/#" -v

msh/US/json/LongFast/!a1b2c3d4 {
  "type": "telemetry",
  "payload": {
    "deviceMetrics": {
      "batteryLevel": 85,
      "voltage": 4.1
    }
  }
}

Configuration Notes

  • Meshtastic MQTT Module: Enable in device config. Set broker address, username, password, and root topic.
  • JSON Mode: Enable JSON output for structured messages instead of protobuf.
  • Encryption Key: Must match other nodes on the mesh for decryption to work.
  • WiFi: Gateway needs reliable WiFi connection to MQTT broker. Static IP recommended.
