Add NervesHub to your project

The first step is to add nerves_hub to your target dependencies in your project's mix.exs. Since NervesHub uses SSL certificates, the time must be set on the device or certificate validity checks will fail. If you're not already setting the time, add nerves_time to your dependencies. For example:
  defp deps(target) do
    [
      {:nerves_runtime, "~> 0.9"},
      {:nerves_hub, "~> 0.1"},
      {:nerves_time, "~> 0.2"},
      ...
    ] ++ system(target)
  end
Next, update your config.exs so that the nerves_hub library can help provision devices. Do this by adding provisioning: :nerves_hub to the :nerves, :firmware option like this:
config :nerves, :firmware,
  provisioning: :nerves_hub
The library won't connect to nerves-hub.org unless requested. The easiest way is to add NervesHub.Supervisor to your main application supervisor:
  defmodule Example.Application do
    use Application
​
    def start(_type, _args) do
​
      opts = [strategy: :one_for_one, name: Example.Supervisor]
      children = [
        NervesHub.Supervisor
      ] ++ children(@target)
      Supervisor.start_link(children, opts)
    end
  end
SSL options can be configured by passing them into the NervesHub supervisor. This is useful for applications that store their ssl credentials in different places, such as NervesKey.
  defmodule Example.Application do
    use Application
​
    def start(_type, _args) do
      {:ok, engine} = NervesKey.PKCS11.load_engine()
      {:ok, i2c} = ATECC508A.Transport.I2C.init([])
      nerves_key_socket_opts = [
        key: NervesKey.PKCS11.private_key(engine, {:i2c, 1}),
        cert: X509.Certificate.to_der(NervesKey.device_cert(i2c)),
        cacerts: [X509.Certificate.to_der(NervesKey.signer_cert(i2c)) | NervesHub.Certificate.ca_certs()],
      ]
​
      opts = [strategy: :one_for_one, name: Example.Supervisor]
      children = [
        {NervesHub.Supervisor, nerves_key_socket_opts}
      ] ++ children(@target)
      Supervisor.start_link(children, opts)
    end
  end
