K5 How to keep kindle alive? without physical touch? (using xdotool)

hi, i control my kindle via ssh, to turn the pages, this is done via xdotool.
after 10 minutes or so, the paperwhite goes to sleep, since it has not recieve any touch. because the 'touch' it is getting is form xdotool, not the screen.

i do not want to disable the kindle from sleeping because, i still want my kindle to sleep. i do not want to have to remember to disable and then renable the sleeping each time i want to use my kindle remotely.

is there any command that can be sent by terminal to keep the kindle alive?
as in, send the command, and then the kindle thinks it just received input, and won't sleep for 10 minutes, unless you send this again.

thanks a lot, i appreciate it :)
