Become an observer

An observer listens to the mesh and forwards every packet it hears to the FWA Mesh analyzer over MQTT. It does not change how your repeater behaves on the air.

What you need

A MeshCore repeater (or observer) running firmware built with MESH_PACKET_LOGGING=1. LetsMesh token auth (optional, below) needs v1.8.0 or newer.
An always-on Linux or macOS machine (a Raspberry Pi is fine) with Python 3.11+, connected to the repeater over USB.
Internet access from that machine to mqtt.fwamesh.net port 1883.

Broker settings

Server	`mqtt.fwamesh.net`
Port	`1883`
Transport	TCP, no TLS
Auth	None
IATA region code	`FWA`

Setup with meshcoretomqtt

Install meshcoretomqtt on the machine attached to your repeater:

curl -fsSL https://raw.githubusercontent.com/Cisien/meshcoretomqtt/main/install.sh | sudo bash

Create /etc/mctomqtt/config.d/99-user.toml:

[general]
iata = "FWA"

[serial]
ports = ["/dev/ttyACM0"]   # or /dev/ttyUSB0

[[broker]]
name = "fwamesh"
enabled = true
server = "mqtt.fwamesh.net"
port = 1883
transport = "tcp"

[broker.tls]
enabled = false

[broker.auth]
method = "none"

Restart the service: sudo systemctl restart mctomqtt, then check it with journalctl -u mctomqtt -f.
Within a few minutes your observer should appear on the observers page under region FWA.

Also feeding LetsMesh?

You can publish to FWA Mesh and LetsMesh at the same time. Add a second [[broker]] block to the same file:

[[broker]]
name = "letsmesh-us"
enabled = true
server = "mqtt-us-v1.letsmesh.net"
port = 443
transport = "websockets"

[broker.tls]
enabled = true

[broker.auth]
method = "token"
audience = "mqtt-us-v1.letsmesh.net"
