"""
Philips Hue lamp
----------------
Very important:
It seems that the device needs to be connected to in the official Philips Hue Bluetooth app
and reset from there to be able to use with Bleak-type of BLE software. After that one needs to
do a encrypted pairing to enable reading and writing of characteristics.
ONLY TESTED IN WINDOWS BACKEND AS OF YET!
