🏁 Basic usage

Listener

defmodule MyListener do
  @moduledoc """
  DemoListener module.
  """
  require Logger

  use GenServer

  def start_link(_) do
    GenServer.start_link(__MODULE__, [])
  end

  @impl true
  def init([]) do
    {:ok, %{listeners: []}}
  end

  @impl true
  def handle_cast({:event, event}, state) do
    Logger.info("#{event.node_identifier}: #{event.event_type}")

    {:noreply, state}
  end
end
{:ok, pid} = ZWave.DemoListener.start_link([])
ZWave.EventBus.register(pid)

Start a network

ZWave.start("/dev/tty.usbmodem142401", "stick1")

Send a command to a node

ZWave.send_command("stick1", "node_3", {:basic_set, 1})
