PowerShell script for sending laptop battery level from Windows10 via UDP to some other host

battery_level.ps1

# ABOUT:
# I needed to have a battery level percentage of my Windows laptop reported to a linux host somehow.
# I am then able to monitor this value and automate switching ON/OFF power supply to keep the laptop
# battery charged in ranges about 20-80%, totaly automatically

# first you need to download this helper script for sending UDP:

# the scripts neeed to be "unblocked" to be able to run from PowerShell using this method:
#dir .\battery_level.ps1|block-File
#dir .\Send-UdpDatagram.ps1|Unblock-File

# I also added this script to be called every minute from Windows task scheduler
# I needed to checkbox to run even on battery (but keep in mind that it won't run anyway if the
# battery level is below ~20% !)
