Build Status

MQTT::Homie

A ruby interface for creating a device conforming to the MQTT Homie convention. This gem builds upon the ruby-mqtt ruby gem.

The Homie convention defines a standardized way of how IoT devices and services announce themselves and their data to a MQTT broker.

Installation

Add this line to your application's Gemfile:

gem 'mqtt-homie'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mqtt-homie

Quick Start

require 'rubygems'
require 'mqtt/homie'

# Set up a device, with a node and properties
device = MQTT::Homie.device_builder(id: 'device', name: 'Device')
  .node(id: "gate", name: "Front gate", type: "Gate")
  .property(id: "state", name: "Gate state", enum: [:open, :closed, :opening, :closing], value: :closed)
  .property(id: "position", name: "Gate position", datatype: :integer, unit: "%", value: 0)
  .property(id: "command", name: "Send gate command", settable: true, enum: [:open, :close]).build

# Create a client and connect to a MQTT broker
client = MQTT::Homie::Client.new(device: device, host: 'localhost')
client.connect

# access nodes and properties of the device
node = device.node('gate')
state = node.property('state')
state.value = :open  # publishes new state to MQTT

# listen for changes to properties via the Observer interface
node.property('command').add_observer(self)
