I’m using an esp-01 1m to turn on and off my PC from my phone. I’ve got it mostly working, but when it first starts up gpio0 and gpio2 ride high on boot, causing my PC to turn on, on boot. I tried using RX (gpio3) but that also rides high (also flickers). Is there any work around for this? Firmware: micropython.

as gpio0 and gpio2 have to be high to boot into your usercode ...
if you are young, have good eyesight and a steady hand you can try to use gpio4 or gpio5 as they are "corner" pins and it should be possible to contact them.
You can use an pulldown to have them low during reset and bootup.
see here for gpios during reset, deepsleep and boot
