I would assume that this is not an application that needs to output a
100% correct pulse train every time. (Based on the assumption that the
telegrams for on and off are different enough.)
You may just repeat the pattern ten times to be safe enough.
Combine it with a light sensor for feedback ;-)
Btw. you may want to increase the priority of your task. I'm using this
code on my Raspi to reduce the interference of other processes with my
media player using Python with gstreamer:
os.system( "sudo renice -15 -p %d"%os.getpid() )
Anyway, Micropython on a microcontroller would probably be the best
solution.
