Discovergy

A client for the Discovergy REST API, providing access to meters and measurements.

Installation

Add :discovergy and :finch to your list of dependencies in mix.exs:

def deps do
  [
    {:discovergy, "~> 0.6"},
    {:finch, "~> 0.16"}
  ]
end

Usage

Create a Discovergy.Client and authenticate with the Discovergy API using your email address and password.

iex> {:ok, client} = Discovergy.Client.new() |> Discovergy.Client.login(email, password)
{:ok, %Discovergy.Client{}}

Then pass the client to the respective endpoint function. For example, to list all meters the user has access to:

iex> Discovergy.Metadata.get_meters(client)
{:ok, [%Discovergy.Meter{
  administration_number: "",
  current_scaling_factor: 1,
  first_measurement_time: 1563286659367,
  full_serial_number: "1ESY1161229886",
  internal_meters: 1,
  last_measurement_time: 1593949473598,
  load_profile_type: "SLP",
  location: %Discovergy.Location{
  city: "Greven",
   country: "DE",
   street: "Sedanstr.",
   street_number: "8",
   zip: "48268"
  },
  manufacturer_id: "ESY",
  measurement_type: "ELECTRICITY",
  meter_id: "c1972a89ce3a4d58aadcb7908a1d31c7",
  scaling_factor: 1,
  serial_number: "61229886",
  type: "EASYMETER",
  voltage_scaling_factor: 1
}]}

Or to obtain the last measurement of a particular meter:

iex> Discovergy.Measurements.get_last_reading(client, "c1972a89ce3a4d58aadcb7908a1d31c7")
{:ok, %Discovergy.Measurement{
  time: ~U[2019-07-16 22:00:00.000Z],
  values: %{
    "energy" => 441576730000,
    "energyOut" => 2154853000,
    "power" => 205980,
    "power1" => 63090,
    "power2" => 53780,
    "power3" => 89100,
    "voltage1" => 234100,
    "voltage2" => 234000,
    "voltage3" => 233800
  }
}}
