I wish to awake my touchpanel via Alexa voice command from backlite off state to on.
I think is a nice idea to control backlight if i need to read something from display for a while and after timetout the screen puts blacklight off.
please how should be correct inserted for executeCommandLine statement:
**shell cmd line:** sudo sh -c 'echo "0" > /sys/class/backlight/rpi_backlight/bl_power' **Rule line not working for me:** executeCommandLine("sudo@@sh@@-c@@'echo@@0@@>@@/sys/class/backlight/rpi_backlight/bl_power")
Thanks for help.
