Thanks for that, but no I am on GPIO 13 (Pin 33)
The script that works fine is:-
Code:
--------------------
#!/bin/sh
# 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.
#---------------------------------------------------------------------------
#===========================================================================
# Test procedure
#---------------------------------------------------------------------------
# sudo killall relay.sh
# sudo sh -c 'echo "17" > /sys/class/gpio/unexport'
# sudo ./relay.sh > /dev/null &
#---------------------------------------------------------------------------
#Wait 1 minute on initial start for pcp_variables to become available
sleep 60

# Set the following according to your setup
#---------------------------------------------------------------------------
#MAC_ADDR=xx:xx:xx:xx:xx:xx # Raspberry Pi MAC
address
MAC_ADDR=$(pcp_controls_mac_address) # Set by pCP
#LMS_IP=xxx.xxx.xxx.xxx # LMS IP address

#---------------------------------------------------------------------------
sudo sh -c 'echo '"$GPIO"' > /sys/class/gpio/export'

# My relay is active low, so this reverses the logic

echo "1" > /sys/class/gpio/gpio$GPIO/value
