# Version: 0.01 2014-11-28 GE
# Original.
#===========================================================================
# This script polls LMS at a regular interval to determine the current
# status of the Squeezelite process on piCorePlayer. i.e. play or stop.
#
# A GPIO is then set/reset depending on the result of this status check.
#
# There is an adjustable relay off delay that can be used as an inactivity
# timing.
#---------------------------------------------------------------------------
#===========================================================================
# Possible issues
#---------------------------------------------------------------------------
# 1. Initial relay status during booting. It is probably better to start
# this script before starting Squeezelite. Also, a pull-up or pull-down
# resistor may be needed to ensure initial state of GPIO.
# 2. If setting MAC address manually, pay close attention to the physical,
# wireless and fake MAC addresses.
# 3. This script hasn't been tested on synced players.
