    Name: Get-TeamsStatus.ps1
    Author: Danny de Vries
    Requires: PowerShell v2 or higher
    Version History: https://github.com/EBOOZ/TeamsStatus/commits/main
.SYNOPSIS
    Sets the status of the Microsoft Teams client to Home Assistant.
.DESCRIPTION
    This script is monitoring the Teams client logfile for certain changes. It
    makes use of two sensors that are created in Home Assistant up front.
    The status entity (sensor.teams_status by default) displays that availability 
    status of your Teams client based on the icon overlay in the taskbar on Windows. 
    The activity entity (sensor.teams_activity by default) shows if you
    are in a call or not based on the App updates deamon, which is paused as soon as 
    you join a call.
.PARAMETER SetStatus
    Run the script with the SetStatus-parameter to set the status of Microsoft Teams
    directly from the commandline.
.EXAMPLE
    .\Get-TeamsStatus.ps1 -SetStatus "Offline"
#>
# Configuring parameter for interactive run
Param($SetStatus)

# Import Settings PowerShell script
. ($PSScriptRoot + "\Settings.ps1")
