#  @package        :   Pi Admin Package
#  @description    :   Got way too many Raspberry Pi's and this package is to
#                      help me with managing them via Home Assistant.
#
#  How Does It Work?
#
#  Each Raspberry Pi runs a service (a python program) locally that listens for
#  commands via MQTT on a pre-defined topic. This package publishes commands
#  to MQTT requesting each Raspberry Pi to respond and or return data.
#  When the responses are received (on a differet topic), the sensors gets
#  updated automatically and are displayed.
