- Examples of the ON & OFF scripts:
(don't forget to give "chmod 755" to the files)
/root/on1.sh
#!/bin/sh
# switch on relay 1
/bin/echo 1 > /sys/devices/platform/leds-gpio.0/leds/DGND3700v1_3800B:blue:wifi5g/brightness
# Insert channel status (1=on, 0=off) for channel recovering after a reboot/crash
/bin/rm /root/status-relay1
/bin/cat /sys/devices/platform/leds-gpio.0/leds/DGND3700v1_3800B:blue:wifi5g/brightness >> /root/status-relay1
/root/off1.sh
#!/bin/sh
# swith off relay 1
/bin/echo 0 > /sys/devices/platform/leds-gpio.0/leds/DGND3700v1_3800B:blue:wifi5g/brightness
# Insert channel status (1=on, 0=off) for channel recovering after a reboot/crash
/bin/rm /root/status-relay1
/bin/cat /sys/devices/platform/leds-gpio.0/leds/DGND3700v1_3800B:blue:wifi5g/brightness >> /root/status-relay1
- Script to extract channel status and restore it at reboot
(put the line: "/bin/sh /root/extract_and_restore-status-relay1.sh" in "/etc/rc.local" right before the "exit 0" line)
/root/extract_and_restore-status-relay1.sh
#!/bin/sh
# extract and restore status of relay1
#
while IFS=: read relay1
do
/bin/echo ${relay1} > /sys/devices/platform/leds-gpio.0/leds/DGND3700v1_3800B:blue:wifi5g/brightness
done < /root/status-relay1
