Installing Home Assistant on Hyper-V

Mon, 25 May 2020 00:00:00 +0000

This post is a quick tutorial you can follow to get Home Assistant working on Hyper-V so you can take advantage of your PC’s compute power instead of running it on a Raspberry Pi. This installation method is really quick and doesn’t require any command line setup.

**Important**: If you want to use USB devices in Home Assistant, please this different tutorial -> [USB Support for Home Assistant on Hyper-V](https://www.dvlup.com/2020/10/23/usb-in-hyper-v/). The approach used in this article doesn't allow for USB devices.

Step 1 - Create Hyper V Machine

Download the VHDX file (hassos_ova-[version].vhdx.gz) from the home-assistant GitHub Releases page .
- I recommend only using the latest non-beta release so you won’t have trouble with HA’s built-in updater. As of writing this, that is version 3.13:
Right-click on the downloaded .gz file, select “Properties”, check the “Unblock” checkbox and click OK.
Extract the .vhdx file from the.gz file (you can use 7-Zip to do this). Don’t worry about where you extract it to, Hyper-V will make a copy.
Open Hyper-V Manager app on Windows 10.
In the right pane, select Quick Create (at the top right).
Choose “Local Installation Source” option for an OS and use the extracted .vhdx file.
You’ll be presented with the VM’s Settings window before starting it up. Here are some recommendations:
- In the Memory tab, set the RAM to at least 2048 MBs or higher and disable Dynamic Memory
- Under the Security tab, make sure Secure Boot is disabled:
- Under the Automatic Stop Action tab, change the setting to “Shut down the guest operating system”:
- Finally, select the Automatic Start Action tab and set your preferred option:
Start the machine and wait for initial setup to complete and you see the Welcome to HassOS prompt.

Using PowerShell to Install an SDK in a DevOps Build Pipeline

Fri, 04 Jan 2019 00:00:00 +0000

I have an open source UWP project that relies on the Ad SDK and Engagement SDK to be installed to Visual Studio. This normally isn’t a problem, because you can just run the MSI on your PC (see installation instructions here and here ).

I decided to move the project into DevOps so that I get some of that CI/CD goodness to build and publish new releases automatically to the Microsoft Store. However, there was a problem, when trying to build the project in a DevOps build pipeline, you’ll get the following error:

LoginDialog for easy Live SDK OAuth

Thu, 06 Dec 2018 00:00:00 +0000

Almost every developer I speak with agrees that getting a nicely working OAuth flow can be difficult. After much trial and error, I’ve built a UWP ContentDialog that makes this easy and has built-in refresh token support.

Using the LoginDialog

This is very simple to use, when the app launches, instantiate the dialog by passing your Live SDK ClientID and let the LoginDialog do the heavy lifting:

// Pass your app's OAuth ClientId (sometimes called an AppId)
var loginDialog = new LoginDialog("YourAppClientId");

// *** Perform login **** //
// Case 1 - If the user was previously signed in, there is a refresh_token stored and no user-entered credentials are needed.
// Case 2 - If the access token fails, or if it's the first sign-in, the user will see a popup to enter credentials.
await loginDialog.SignInAsync();

if(!string.IsNullOrEmpty(loginDialog.Authentication))
{
 // This will be the access token you can use for API calls.
 var accessToken = loginDialog.Authentication;

 // Make your API calls with the accessToken, for example:
 var user = await apiService.GetUserProfileAsync(accessToken);
}

This works just like a MessageDialog, but instead will show a WebView for the user to sign in, or automatically sign them in silently if they were previously logged in.

The RS5 Update Resources and Tutorials

Wed, 03 Oct 2018 00:00:00 +0000

My friends at Microsoft have put together an amazing compilation of resources of all the new stuff available in the Windows 10 October 2018 Update (aka RS5). Below is a list of some of those resources relevant to developers and enthusiasts, enjoy!

SDK Downloads

EXE - http://go.microsoft.com/fwlink/?LinkID=2023014
ISO - http://go.microsoft.com/fwlink/?LinkID=2022797 You can also install the
Visual Studio Installer - Choose the UWP workload and select 17763 SDK under additional components

New Samples and Sample Updates

XAML Hosting API Sample uses the new XAML hosting API and C++/WinRT to demonstrate usage of XAML controls within a Win32 application.
Customer Orders Database Sample has been updated to use the new Data Grid and other new controls in RS5.
Photo Editor C++/WinRT Sample has been updated to build with the RS5 SDK and to use the new single_threaded_observable_vector function to create an IObservableVector for data binding. An additional performance update will be coming out in a couple weeks.
Data binding and MVVM is a new topic that was identified as a need based on the Code First program. The topic describes the benefits of using the MVVM design pattern and how it has been applied to the sample apps.

Creating 3D Icons for your Mixed Reality UWP app

Wed, 06 Sep 2017 00:00:00 +0000

Microsoft has opened up the ability to have a 3D app launcher to all developers in the Fall Creator’s Update. In this blog post, I’m going to show you how to build your own 3D app launcher from scratch (accompanying YouTube tutorial video embedded below).

What is a 3D app launcher?

App Launchers

Up until now, you’ve only been able to have a regular 2D tile in the Start menu and the user could place a 2D frame of your app on a surface in the Cliff House (the Mixed Reality home) or on a surface in your HoloLens mapped area. Clicking the app frame would launch the app in the same frame.

"Cannot download Windows Mixed Reality software" error fix!

Thu, 03 Aug 2017 00:00:00 +0000

Did you just get a new Mixed Reality headset? Were you so excited that you ripped open the box and plugged it in only to to find that after setting up your floor and boundaries that you got the following error:

Cannot download Windows Mixed Reality software

Screeching halt!

I spent a lot of time digging around the Hololens forums and long conversations on the Holodevelopers Slack and it seemed there was a wide variety of reason for this. However, after looking at my Developer Mode settings page (in Windows Settings), there was an incomplete dev package installation.

Easy XamlCompositionBrushBase

Sun, 18 Jun 2017 00:00:00 +0000

The upcoming Windows 10 update, the Fall Creator’s Update, introduces a new design system, Microsoft Fluent Design System . The design system has 5 major building blocks:

Light
Depth
Motion
Material
Scale

You can use any of these in a multitude of ways, however Microsoft has made it very easy to use in the latest Preview SDK (16190). Some of the things that used to be relatively hard, or at the least verbose, can now be done with a few lines of code.

Adding Telerik Universal

Mon, 10 Nov 2014 00:00:00 +0000

Telerik has released a new toolset, UI for Windows Universal . You can now use many components like Charts and Calendars in a shared XAML page in your application. If you already have the Telerik Windows Phone or Windows 8.1 XAML controls, you now have a license for the Universal controls, too.

It is very simple to add it to your project. Let me show you in a quick File > New example:
