Re: Powering a raspberry pi 4 on a PC monitor without USB?

most TV USB sockets will not give enough power to power a raspberry pi, [pizero excluded]
use a proper USB power supply - like the raspberry pi one to power your RPi , from a 2nd wall socket

Re: Loss of power to RPi and rc.local not running

also in rc.local you are already running as root so no need to do that
you code should not need sudo so don't use it unless you need to
a systemd.service file is the way to do this properly that way you can enable to restart the program if it crashes for what ever reason during the day
