+	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.
+    sensor.teams_status displays that availability status of your Teams client based 
+    on the icon overlay in the taskbar on Windows. sensor.teams_activity 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.
