    deployHA

Wanted to deploy Home Assistant to a Windows 2016 Nano Server. For fun I figured I'd create a script to deploy it effortlessly. This script would probably work for any newer version of Windows although I haven't tested that.
You should have the x64 version of Python 3.5. I tested this version specifically. If you changed the install path from the default you should specify the install path as the second argument.
.\deployHA.ps1 servername-or-ip path-2-Python-3.5(optional) "Time Zone"

# Example Usages:

.\deployHA.ps1 ha C:\Python-Custom-Path\Python35 "Pacific Standard Time"

.\deployHA.ps1 ha C:\Python-Custom-Path\Python35

.\deployHA.ps1 10.30.50.25

.\deployHA.ps1 
.\restartHA.ps1 servername-or-ip

# Example Usages:

.\restartHA.ps1 ha

.\restartHA.ps1 10.30.50.25

.\restartHA.ps1 

If you haven't deployed a Nano Server here's a generic jist
Domain version

Need to run from domain joined computer in administrator powershell prompt
Assumes D:\ is a mounted Server 2016 ISO
$VMName = "ComputerName"
$InstallDisk = "D:\"
$Domain = "corp.contoso.com"

Djoin.exe /provision /domain $Domain /machine $VMName /savefile "$env:temp\blobNano-$VMName"

Import-Module "$InstallDisk\NanoServer\NanoServerImageGenerator\NanoServerImageGenerator" -Verbose

New-NanoServerImage -Edition Standard -DeploymentType Guest -MediaPath $InstallDisk -TargetPath "$($(Get-VMHost).VirtualHardDiskPath)$VMName.vhdx" -DomainBlobPath "$env:temp\blobNano-$VMName"

Workgroup version

Assumes D:\ is a mounted Server 2016 ISO
Import-Module D:\NanoServer\NanoServerImageGenerator\NanoServerImageGenerator -Verbose

New-NanoServerImage -Edition Standard -DeploymentType Guest -MediaPath

Then create a new Generation 2 VM in Hyper-V using the disk you just created. Start it up and run the powershell script.
