Meshtastic Nodes via MQTT for Home Assistant

Meshtastic MQTT Client

• Integration uses Protobuf MQTT outputs, available through the HA MQTT Server. No JSON outputs are needed
• Supports encrypted outputs
• Exposes various sensor values available from Meshtastic nodes
• Implements Device Tracker showing latest reported position

Installation

• Install this repo via HACS (custom integration repository)

Configuration

• In order to register new node in your Home Assistant, you need 2-3 things:
  • Node ID: e.g. !aabbccdd
  • Protobuf MQTT topic: e.g. msh/EU_868/2/c/LongFast/!aabbccdd
  • Optionally, Base64 encoded encryption key as it appears in the mobile app (copy/paste)
  • Optionally, stat MQTT topic: e.g. msh/EU_868/2/stat/!aabbccdd

How to make Meshtastic public MQTT server data available in your local MQTT server?

• You can utilize MQTT Bridge functionality
• I'm using Mosquitto, and I have the following lines in my configuration file (with real node IDs):

connection meshtastic
address mqtt.meshtastic.org

topic +/+/!e2e2xxxx in 0 meshtastic/ msh/EU_868/2/
topic +/+/!3032yyyy in 0 meshtastic/ msh/EU_868/2/

topic !3032xxxx in 0 meshtastic/stat/ msh/EU_868/2/stat/
topic !e2e2yyyy in 0 meshtastic/stat/ msh/EU_868/2/stat/

• Using that, all topics are available in my local MQTT server under meshtastic/ root topic
