mqtt_things

status: working but very coupled to my own personal projects

This repo is mostly Go, with a little bit of Rust and some Arduino-flavoured C++.

It's pretty tightly coupled to my home automation setup, but there might be a few useful things in there for you; of note:

• cmd
  • aircons_cli
    • Limited MQTT integration of my old Fujtsi aircon and Mitsubishi aircon via Zmote
  • arp_cli
    • Linux-only MQTT integration that reports whether or not specific MAC addresses / IP addresses are present on the local network
    • I was using this as a "home or not" sensor
  • circumstances_cli
    • Some bespoke stuff I was using in the pre-home-assistant days to publish composed states for me to do things with
      • e.g. it's after this time of day and OpenWeather says its sunny
  • heater_cli
    • MQTT integration w/ res/arduino for controlling a relay that turns on / off the gas heater in my living room
  • http_cli
    • A generalized thing to expose the state of an MQTT broker's topics as a JSON HTTP API

  • lights_cli

    • Limited MQTT integration of Philips Hue lights
  • mqtt_to_glue_bridge
    • Bridge between MQTT and Glue (my own brokerless pub-sub lib)
  • sensors_cli
    • Limited MQTT integration of Philips Hue presence / temperature sensors
  • smart_aircons_cli
    • Limited MQTT integration of my old Fujitsi aircon, Mitsubishi aircon and new Fujitsu aircons via Zmote and Broadlink RM4 Mini
      • There's a reasonable Broadlink RM4 Mini library you can use here
  • sprinklers_cli
    • MQTT integration w/ res/arduino for controlling two relays that turn on / off my banks of sprinklers

  • switches_cli

    • Limited MQTT integration for switching on / off some smartplugs running Tasmota firmware
  • topic_cli
    • Handy debugging tool for subscribing to / publishing to MQTT topics
  • topic_exporter_cli
  • A generalized thing to expose the state of an MQTT broker's topics as a Prometheus exporter
  • open_weather_cli
    • MQTT integration for OpenWeather
      • NOTE: This uses the 2.5 API which they're apparently deprecating sometime in 2024, so it's basically just garbage now
