Home Assistant config :

Generate id_rsa and id_rsa.pub in /config/

add Switch config :

add Shell Command config :

Windows 10 config :

Manage optional features > Add a feature > OpenSSH Server > Install
Open “services.msc” , select “OpenSSH SSH Server” > Startup type > Automatic
Restart Windows 10.

Enable Wake-On-LAN in the BIOS

Enable Wake-On-LAN in the “Devices Manager”
Network Adapters > Select the WiFi card > right click Properties > Power Management > Allow this device to wake the computer + Only allow a magic packet to wake the computer -> CHECK BOTH

Allow HA to ping Windows, for HA to see the Windows state : Windows Defencer Firewall > Advanced settings > File and Printer Sharing (Echo Request - ICMPv4-In) (TWO RULES) > right click and “Enable rule”

Open Notepad as Administrator, add the content of id_rsa.pub in C:\ProgramData\ssh\administrators_authorized_keys with no extension
Set the permissions with PowerShell as Admin :

$acl = Get-Acl C:\ProgramData\ssh\administrators_authorized_keys
$acl.SetAccessRuleProtection($true, $false)
$administratorsRule = New-Object system.security.accesscontrol.filesystemaccessrule("Administrators","FullControl","Allow")
$systemRule = New-Object system.security.accesscontrol.filesystemaccessrule("SYSTEM","FullControl","Allow")
$acl.SetAccessRule($administratorsRule)
$acl.SetAccessRule($systemRule)
$acl | Set-Acl
