Genmon XFCE panel to show phone battery level via adb

ACTION=="add|remove", SUBSYSTEM=="usb", ATTRS{idVendor}=="XXXX", ATTRS{idProduct}=="XXXX", RUN+="/usr/bin/su YOUR_USER_NAME /path/to/refresh-genmon-udev.sh"
# replace YOUR_USER_NAME with your actual user name (hardcoded, this is ran by root, it's possible to determin your user name
# by finding out who is the owner of xfce4-panel
# You'll also have to replace XXXX with the output from lsusb
# for example:
# Bus 001 Device 094: ID 046d:c05a Logitech, Inc. M90/M100 Optical Mouse
# After the term ID this is the code we're after, 046d is the idVendor code while c05a is the idProduct code
# Better have that hardcoded as well
# This file should be in /etc/udev/rules.d (at least on RedHat based and Arch based) and requires root permissions to edit.

#!/bin/bash

# First add a genmon item to the XFCE panel.

# This script is checking for connectivity, on no connectivity a red N/A message will appear.
# If there is connectivity the script will show the battery precentage in a color varying from 
# red (empty) to green (full) and a bar next to it (can be more granular but that's highly
# unnecessary, yet possible).
# The output is formated to also display a tooltip showing some more data like phone type.
# A click can also be implemented but I didn't find any use for it.
