HADotNet

Nuget

A simple, straightforward .NET Standard library for the Home Assistant API.

Fork

This repository is the fork of original one by qJake.

Aim of the fork is to provide maintenance & feature updates as part of HASS.Agent development.

Features

  • .NET 8 cross-platform library
  • DI-friendly client initialization (suitable for ASP.NET Core)
  • Home Assistant data is represented by strongly-typed, commented model classes

Supported Home Assistant APIs

  • Root API (Verifies the HA API is responding)
  • Automation API
  • Google Calendar API (Unofficial)
  • Discovery API
  • Config API
  • Camera Proxy API
  • Entity API
  • Error Log API
  • Events API
  • History API
  • Logbook API
  • Services API
  • States API
  • Supervisor API (Supervisor-based installations only)
  • Template API

Getting Started

Nuget

Install Amadeo.HADotNet.Core from NuGet:

Install-Package Amadeo.HADotNet.Core

From Source

Clone this repo and either include the Amadeo.HADotNet.Core library in your project, or build the project and include the DLL as a reference.

Examples

Initializing The Client Factory

The ClientFactory class is reponsible for initializing all other clients in a reusable way, so you only have to define your instance URL and API key once.

To initialize the ClientFactory, pass in your base Home Assistant URL and a long-lived access token that you created on your profile page.

ClientFactory.Initialize("https://my-home-assistant-url/", "AbCdEf0123456789...");

Integrating into an ASP.NET Core Site

First, call ClientFactory.Initialize(...); to ensure that your Home Assistant instance is connected. You can do this in ConfigureServices, or using middleware.

Just be sure that the client factory has been initialized before any page/controller requests are made.

You can add individual clients to the DI container like so:

services.AddScoped(_ => ClientFactory.GetClient<EntityClient>());
services.AddScoped(_ => ClientFactory.GetClient<StatesClient>());
services.AddScoped(_ => ClientFactory.GetClient<ServiceClient>());
services.AddScoped(_ => ClientFactory.GetClient<DiscoveryClient>());

Since there are no interfaces, simply add the instance(s) directly into the container. Add as few or as many clients as you need, and then simply retrieve each client via the DI container as-needed.

public class MyController : Controller
{
	private IOtherService SampleService { get; }
	private EntityClient EntityClient { get; }

	public MyController(IOtherService sampleService, EntityClient entityClient)
	{
		SampleService = sampleService;
		EntityClient = entityClient;
	}

	// ...
}

Getting Home Assistant's Current Configuration

Get a ConfigClient and then call GetConfiguration():

var configClient = ClientFactory.GetClient<ConfigClient>();
var config = await configClient.GetConfiguration();
// config.LocationName: "Home"
// config.Version: 0.96.1

Retrieving All Entities

Get an EntityClient and then call GetEntities():

var entityClient = ClientFactory.GetClient<EntityClient>();
var entityList = await entityClient.GetEntities();

Retrieving Entities By Domain

Get an EntityClient and then call GetEntities("domainName"):

var entityClient = ClientFactory.GetClient<EntityClient>();
var filteredEntityList = await entityClient.GetEntities("light");

Retrieving All Entity States

Get a StatesClient and then call GetStates():

var statesClient = ClientFactory.GetClient<StatesClient>();
var allMyStates = await statesClient.GetStates();

Retrieving State By Entity

Get a StatesClient and then call GetState(entity):

var statesClient = ClientFactory.GetClient<StatesClient>();
var state = await statesClient.GetState("sun.sun");
// state.EntityId: "sun.sun"
// state.State: "below_horizon"

Retrieving All Service Definitions

Get a ServiceClient and then call GetServices():

var serviceClient = ClientFactory.GetClient<ServiceClient>();
var services = await serviceClient.GetServices();

Retrieving Calendar Events

Get a CalendarClient and then call GetEvents(calEntity):

var calClient = ClientFactory.GetClient<CalendarClient>();
var myEvents = await calClient.GetEvents("calendar.my_calendar");

Calling a Service

Get a ServiceClient and then call CallService():

var serviceClient = ClientFactory.GetClient<ServiceClient>();

var resultingState = await serviceClient.CallService("homeassistant", "restart");
// Or
var resultingState = await serviceClient.CallService("light", "turn_on", new { entity_id = "light.my_light" });
// Or
var resultingState = await serviceClient.CallService("light.turn_on", new { entity_id = "light.my_light" });
// Or
var resultingState = await serviceClient.CallService("light.turn_on", @"{""entity_id"":""light.my_light""}");

Retrieving History for an Entity

Get a HistoryClient and then call GetHistory(entityId):

var historyClient = ClientFactory.GetClient<HistoryClient>();
var historyList = await historyClient.GetHistory("sun.sun");

// historyList.EntityId: "sun.sun"
// historyList[0].State: "above_horizon"
// historyList[0].LastUpdated: 2019-07-25 07:25:00
// historyList[1].State: "below_horizon"
// historyList[1].LastUpdated: 2019-07-25 20:06:00

Rendering a Template

Get a TemplateClient and then call RenderTemplate(templateBody):

var templateClient = ClientFactory.GetClient<TemplateClient>();
var myRenderedTemplate = await templateClient.RenderTemplate("The sun is {{ states('sun.sun') }}");

// myRenderedTemplate: The sun is above_horizon

Retrieving a Camera Image

Get a CameraProxyClient and then call GetCameraImage, or for a ready-to-go HTML Base64 string, GetCameraImageAsBase64:

var cameraClient = ClientFactory.GetClient<CameraProxyClient>();
var myCameraImage = await cameraClient.GetCameraImageAsBase64("camera.my_camera");

// myCameraImage: "data:image/jpg;base64,AAAAAAAAA..."

To run the unit tests, you must first set two environment variables:

  • HADotNet:Tests:Instance = https://my-home-assistant-url/
  • HADotNet:Tests:ApiKey = AbCdEf0123456789...
